Abstract
BACKGROUND Enteral ibuprofen was first approved as a prescription drug in 1974 for the US market. An intravenous (IV) ibuprofen formulation is approved for use in children older than 6 months of age, but there are limited studies specifically evaluating the pharmacokinetics and safety in children 1-6 months of age. AIMS The primary purpose of this study was to evaluate the pharmacokinetics of IV ibuprofen in infants younger than 6 months of age. The secondary objective was to evaluate the safety of single and repeated doses of IV ibuprofen in infants younger than 6 months of age. METHODS This was an industry-sponsored multi-center study. Institutional Review Board approval and informed parental consent were obtained prior to enrollment. Hospitalized neonates and infants younger than 6 months of age with fever or expected postoperative pain were eligible. Enrolled patients received 10 mg/kg of IV ibuprofen every 6 h, with up to four doses per day. Patients were randomized to two sparse sampling technique pharmacokinetic sample time groups. Group 1 samples were drawn at 0, 30 min, and 2 h, while group 2 samples were drawn at 0 min, 1, and 4 h after administration. RESULTS A total of 24 children were enrolled in the study, with 15 male patients and 9 female patients. The median age of the cohort was 4.4 months (range 1.1-5.9 months), and the median weight was 5.9 kg (range 2.3-8.8 kg). The arithmetic mean and standard error for peak plasma ibuprofen concentration was 56.28 ± 2.77 µg/mL. Plasma levels declined rapidly with a mean elimination half-life of 1.30 h. Time to peak ibuprofen effect and concentration were similar when compared with older pediatric patients. Clearance and volume of distribution were also similar to those reported in older pediatric patients. No drug-related adverse events were reported. CONCLUSIONS The pharmacokinetic and short-term safety profiles of IV ibuprofen in pediatric patients 1-6 months of age are comparable to those in children older than 6 months of age. TRIAL REGISTRATION Clinicaltrials.gov Trial Registration number and date: NCT02583399-Registered July 2017.

Chiral pharmacokinetics of ibuprofen enantiomers in Chinese preterm neonates with patent ductus arteriosus using a validated UHPLC-MS/MS method. J Chromatogr B Analyt Technol Biomed Life Sci 2023; 1227:123765. [PMID: 37454407 DOI: 10.1016/j.jchromb.2023.123765] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 05/17/2023] [Accepted: 05/22/2023] [Indexed: 07/18/2023]
Abstract
Persistent patent ductus arteriosus (PDA) is generally observed in preterm neonates. Oral ibuprofen is the standard treatment for closing PDA in China. To investigate the chiral pharmacokinetics of ibuprofen enantiomers in Chinese premature infants with PDA, a simple, fast, and sensitive analytical enantioselective technology was developed with ultra-performance liquid chromatography (UPLC) - tandem mass spectrometry (MS/MS). Chromatographic separation of (R)-ibuprofen and (S)-ibuprofen was accomplished on a Lux® 3 µm Cellulose-3 (150 mm × 2.0 mm, 3 μm) at a flow rate of 0.2 mL/min within 6 min. UPLC separation was achieved by isocratic elution with a mobile phase consisting of formic acid:water (75:1000000, v/v) and acetonitrile:methanol (1:1, v/v). Only 50 µL of plasma samples were pre-treated with acetonitrile precipitation. Ibuprofen-d3 was used as an internal standard. The standard curves of both enantiomers were linear over a concentration range of 0.0500 μg/mL to 50.00 μg/mL. The method has been validated for selectivity, carryover effect, lower limit of quantification, precision, accuracy, matrix effect, extraction recovery, dilution integrity, and stability based on the existing guidelines of the National Medical Products Administration, the United States Food and Drug Administration, and the European Medicines Agency. This method has been successfully applied to investigate the pharmacokinetics of ibuprofen enantiomers in 9 preterm infants with PDA. Our results showed that a high chiral inversion ratio of (R)- to (S)-ibuprofen exists in Chinese preterm neonates. Further studies should be conducted to monitor drug concentration following oral administration of ibuprofen and to consider the effect of individual variations and ethnic differences in metabolizing enantiomers of ibuprofen in premature neonates with PDA.

CHILDREN (BASEL, SWITZERLAND) 2023; 10:926.

Abstract
Hyperbilirubinemia is a common pathological condition in neonates. Free bilirubin can penetrate the blood-brain barrier (BBB), which can lead to bilirubin neurotoxicity. In the context of predicting the risk of bilirubin neurotoxicity, although the specificity and sensitivity of free bilirubin levels are higher than those of total serum bilirubin (TSB), free bilirubin is not widely monitored in clinical practice. The threshold TSB levels at which phototherapy must be administered have been established previously. However, TSB levels are not well correlated with neurodevelopmental outcomes. Currently, TSB levels are commonly used to guide phototherapy for neonatal hyperbilirubinemia. Some clinical drugs can displace bilirubin from its albumin-binding sites, and consequently upregulate plasma bilirubin. Daily dosages play a vital role in regulating bilirubin levels. A drug with both a high protein binding capacity and high daily dosage significantly increases bilirubin levels in infants. Premature or very low birth weight (VLBW) infants are vulnerable to the upregulation of bilirubin levels as they exhibit the lowest reserve albumin levels and consequently the highest bilirubin toxicity index. Because bilirubin is involved in maintaining the balance between pro-oxidant and antioxidant agents, the downregulation of bilirubin levels is not always desirable. This review provides insights into the impact of protein binding capacity and daily dosage of drugs on the bilirubin levels in susceptible infants.

Abstract
OBJECTIVE Exploration of a novel therapeutic drug monitoring (TDM) strategy to personalise use of ibuprofen for closure of patent ductus arteriosus (PDA) in preterm neonates. DESIGN Prospective, single-centre, open-label, pharmacokinetics study in preterm neonates. SETTING Neonatal intensive care unit at McMaster Children's Hospital. PATIENTS Neonates with a gestational age ≤28+6 weeks treated with oral ibuprofen for closure of a PDA. METHODS Population pharmacokinetic parameters, concentration-time profiles and exposure metrics were obtained using pharmacometric modelling and simulation. MAIN OUTCOME MEASURE Association between ibuprofen plasma concentrations measured at various sampling time points on the first day of treatment and attainment of the target exposure over the first 3 days of treatment (AUC0-72h >900 mg·hour/L). RESULTS Twenty-three preterm neonates (median birth weight 780 g and gestational age 25.9 weeks) were included, yielding 155 plasma ibuprofen plasma samples. Starting from 8 hours' postdose on the first day, a strong correlation between ibuprofen concentrations and AUC0-72h was observed. At 8 hours after the first dose, an ibuprofen concentration >20.5 mg/L was associated with a 90% probability of reaching the target exposure. CONCLUSION We designed a novel and practical TDM strategy and have shown that the chance of reaching the target exposure (AUC0-72h >900 mg·hour/L) can be predicted with a single sample collection on the first day of treatment. This newly acquired knowledge can be leveraged to personalise ibuprofen dosing regimens and improve the efficacy of ibuprofen use for pharmacological closure of a PDA.

Abstract
BACKGROUND Developmental physiology can alter pharmacotherapy in preterm populations. Because of ethical and clinical constraints in studying this vulnerable age group, physiologically based pharmacokinetic models offer a viable alternative approach to predicting drug pharmacokinetics and pharmacodynamics in this population. However, such models require comprehensive information on the changes of anatomical, physiological and biochemical variables, where such data are not available in a single source. OBJECTIVE The objective of this study was to integrate the relevant physiological parameters required to build a physiologically based pharmacokinetic model for the preterm population. METHODS Published information on developmental preterm physiology and some drug-metabolising enzymes were collated and analysed. Equations were generated to describe the changes in parameter values during growth. RESULTS Data on organ size show different growth patterns that were quantified as functions of bodyweight to retain physiological variability and correlation. Protein binding data were quantified as functions of age as the body weight was not reported in the original articles. Ontogeny functions were derived for cytochrome P450 1A2, 3A4 and 2C9. Tissue composition values and how they change with age are limited. CONCLUSIONS Despite the limitations identified in the availability of some tissue composition values, the data presented in this article provide an integrated resource of system parameters needed for building a preterm physiologically based pharmacokinetic model.

Abstract
BACKGROUND Preterm neonates are usually not part of a traditional drug development programme, however they are frequently administered medicines. Developing modelling and simulation tools, such as physiologically based pharmacokinetic (PBPK) models that incorporate developmental physiology and maturation of drug metabolism, can be used to predict drug exposure in this group of patients, and may help to optimize drug dose adjustment. OBJECTIVE The aim of this study was to assess and verify the predictability of a preterm PBPK model using compounds that undergo diverse renal and/or hepatic clearance based on the knowledge of their disposition in adults. METHODS A PBPK model was developed in the Simcyp Simulator V17 to predict the pharmacokinetics (PK) of drugs in preterm neonates. Drug parameters for alfentanil, midazolam, caffeine, ibuprofen, gentamicin and vancomycin were collated from the literature. Predicted PK parameters and profiles were compared against the observed data. RESULTS The preterm PBPK model predicted the PK changes of the six compounds using ontogeny functions for cytochrome P450 (CYP) 1A2, CYP2C9 and CYP3A4 after oral and intravenous administrations. For gentamicin and vancomycin, the maturation of renal function was able to predict the exposure of these two compounds after intravenous administration. All PK parameter predictions were within a twofold error criteria. CONCLUSION While the developed preterm model for the prediction of PK behaviour in preterm patients is not intended to replace clinical studies, it can potentially help with deciding on first-time dosing in this population and study design in the absence of clinical data.

Abstract
S(+)-ibuprofen (S-IBU) and R(-)-ibuprofen (R-IBU) concentrations were measured in 16 neonates with patent ductus arteriosus during a cycle of therapy (three intravenous doses of 10-5-5 mg kg-1 at 24-h intervals), at the end of the first infusion and 6, 24, 48, and 72 h later. Data were analyzed with a PK model that included enantiomer elimination rate constants and the R- to S-IBU conversion rate constant. The T½ of S-IBU in the newborn was much longer than in adults (41.8 vs. ≈2 h), whereas the T½ of R-IBU appeared to be the same (2.3 h). The mean fraction of R- to S-IBU conversion was much the same as in adults (0.41 vs. ≈0.60). S-IBU concentrations measured 6 h after the first dose were higher than at the end of the infusion in 10 out of 16 cases, and in five cases, they remained higher even after 24 h. This behavior is unprecedented and may be attributable to a rapid R-to-S conversion overlapping with a slow S-IBU elimination rate. In 13 of the 16 neonates, S-IBU concentrations at 48 and/or 72 h were lower than expected, probably due to the rapid postnatal maturation of the newborn's liver metabolism.

Abstract
Background The optimal management of PDA in very low birth weight (VLBW) infants is still controversial. Aim of our study was to investigate the management of PDA in the Italian neonatal intensive care units (NICU). Methods We conducted an on-line survey study from June to September 2017. A 50-items questionnaire was developed by the Italian Neonatal Cardiology Study Group and was sent to Italian NICUs. Results The overall response rate was 72%. Diagnosis of PDA was done by neonatologists, cardiologists or both (62, 12 and 28% respectively). PDA significance was assessed by a comprehensive approach in all centers, although we found a heterogeneous combination of parameters and cut-offs used. None used prophylactic treatment. 19% of centers treated PDA in the first 24 h, 60% after the first 24 h, following screening echocardiography or clinical symptoms, 18% after the first 72 h and 2% after the first week. In the first course of treatment ibuprofen, indomethacin and paracetamol were used in 87, 6 and 7% of centers respectively. Median of surgical ligation was 3% (1–6%). Conclusions Significant variations exist in the management of PDA in Italy. Conservative strategy and targeted treatment to infants older than 24 h with echocardiographic signs of hemodynamic significance seemed to be the most adopted approach.

Abstract
In this review of analgesic and sedation medication in neonates, important classes of old and newer medications commonly used in the neonatal intensive care unit setting are discussed. In addition to drug metabolism, efficacy, and safety for individual drugs, new insights into multimodal analgesic approaches suggest ways in which multiple analgesic drug classes can be combined to maximize efficacy and minimize toxicity. Opiate pharmacogenetics and the potential for a precision therapeutics approach is explored, with a final description of gaps in knowledge and a call for future research of pain and sedation control in the neonatal population.

Abstract
BACKGROUND Ibuprofen is widely used for ductus arteriosus closure in premature neonates and for analgesia in children and adults. There are no maturation descriptors of clearance. This lack of maturation understanding limits dosing recommendations from premature neonates to adulthood. METHODS Published clearance estimates from different aged patients determined after administration from time-concentration profiles were used to construct a maturation model based on size and age. Curve fitting was performed using nonlinear mixed-effects models. A target concentration strategy was used to estimate maintenance dose at different ages. RESULTS There were three publications reporting an estimate of individual clearance estimates in premature neonates, three reporting population clearances in infants, 11 in children 2-15 years (1 with individual and 9 with population clearances), and 13 adult studies (1 with individual and 12 with population clearances). Clearance maturation, standardized to a 70 kg person was described using the Hill equation. Mature clearance was 3.81 (CV 15.5%, 95%CI 3.72, 3.92) L/h/70 kg. The maturation half-time was 36.8 (CV 9.2%, 95%CI 34.7, 40.9) weeks postmenstrual age and the Hill coefficient 11.5 (95%CI 8.1, 15). A target effect of four units (visual analogue scale 0-10) correlated with an effect site concentration of 6.3 mg/L: a concentration achieved at trough after 400 mg 8 hourly in adults. CONCLUSION Previously published pharmacokinetic parameters can be used to develop maturation models that address gaps in current knowledge regarding the influence of age on a drug's disposition. Maturation of ibuprofen clearance was rapid and was 90% of adult values by the first month of life in term neonates (ie, 44 weeks postmenstrual age) and 98% of standardized adult estimates by 3 months of age (53 weeks postmenstrual age). Clearance informed dosing predictions in all ages (premature neonate to adult) and matched those doses in common use in children older than 3 months.

Simulation-based suggestions to improve ibuprofen dosing for patent ductus arteriosus in preterm newborns. Eur J Clin Pharmacol 2018; 74:1585-1591.

Abstract
Purpose Ibuprofen is the drug of choice for treatment of patent ductus arteriosus (PDA). There is accumulating evidence that current ibuprofen-dosing regimens for PDA treatment are inadequate. We aimed to propose an improved dosing regimen, based on all current knowledge. Methods We performed a literature search on the clinical pharmacology and effectiveness of ibuprofen. (R)- and (S)-ibuprofen plasma concentration-time profiles of different dosing regimens were simulated using a population pharmacokinetic model and evaluated to obtain a safe, yet likely more efficacious ibuprofen exposure. Results The most effective intravenous ibuprofen dosing in previous clinical trials included a first dose of 20 mg kg−1 followed by 10 mg kg−1 every 24 h. Simulations of this dosing regimen show an (S)-ibuprofen trough concentration of 43 mg L−1 is reached at 48 h, which we assumed the target through concentration. We show that this target can be reached with a first dose of 18 mg kg−1, followed by 4 mg kg−1 every 12 h. After 96 h postnatal age, the dose should be increased to 5 mg kg−1 every 12 h due to maturation of clearance. This twice-daily dosing has the advantage over once-daily dosing that an effective trough level may be maintained, while peak concentrations are substantially (22%) lower. Conclusions We propose to improve intermittent ibuprofen-dosing regimens by starting with a high first dose followed by a twice-daily maintenance dosing regimen that requires increase over time and should be continued until sufficient effect has been achieved.

Abstract
Nonsteroidal antiinflammatory drugs (NSAIDs) and acetaminophen are used in young infants and newborns for pain and fever control, patent ductus closure, prevention of intraventricular hemorrhage, and potentially for prevention of retinopathy of prematurity. These drugs inhibit cyclooxygenase 1 (COX-1), COX-2, and peroxidases, thus, blocking prostaglandin (PG) synthesis. PGs are eicosanoids that regulate several physiologic, pathologic, and cellular processes, including vasomotor tone, platelet aggregation, sensitization of neurons to pain, and many molecular events critical to physiologic homeostasis. NSAIDs inhibit caspases and cell death. Increasing knowledge of these molecular entities may allow targeted drug development to prevent or minimize neonatal morbidities.

Abstract
Ibuprofen is a non-steroidal anti-inflammatory drug frequently administered to children of various ages for relief of fever and pain and is approved as an over-the-counter medication in many countries worldwide. Although there are extensive data on its efficacy and safety in children and adults, there are divergent dosing recommendations for analgesia and treatment of fever in infants, especially in the age group between 3 and 6 months of age. In this article, we have assessed the safety and efficacy of ibuprofen use in infants in an attempt to find the optimal method of pain and fever management in this specific age group. Based on the current evidence, short-term use of ibuprofen is considered safe in infants older than 3 months of age having a body weight above 5-6 kg when special attention is given to the hydration of the patient. Ibuprofen should be prescribed based on body weight using a dose of 5-10 mg/kg. This dose can be administered 3-4 times a day resulting in a maximum total daily dose of 30-40 mg/kg. The rectal route has been shown to be less reliable because of erratic absorption, especially in young infants. Since most efficacy and safety data have been derived from trials in infants with fever, future studies should focus on the efficacy of ibuprofen in young infants with pain.

Abstract
Total serum/plasma bilirubin (TB), the biochemical measure currently used to evaluate and manage hyperbilirubinemia, is not a useful predictor of bilirubin-induced neurotoxicity in premature infants. Altered bilirubin-albumin binding in premature infants limits the usefulness of TB in premature infants. In this article, bilirubin-albumin binding, a modifying factor for bilirubin-induced neurotoxicity, in premature infants is reviewed.

Abstract
OBJECTIVE To compare the efficacy of intravenous ibuprofen at high (20-10-10mg/kg/dose) and low doses (10-5-5mg/kg/dose) the closure of patent ductus arteriosus in preterm newborns. METHODS A cohort study with historical control of newborns that received high- and low-dose intravenous ibuprofen, from 2010 to 2013 in a neonatal intensive care unit, for closure of the patent ductus arteriosus, documented by echocardiography. Secondary outcomes included the number of ibuprofen cycles, incidence of bronchopulmonary dysplasia, necrotizing enterocolitis, changes in renal function, and death. RESULTS Seventy-seven patients received three doses of ibuprofen for the treatment of patent ductus arteriosus, with 33 receiving high-dose and 44 low-dose therapy. The ductus closed after the first cycle in 25 (56.8%) low-dose patients and in 17 (51.5%) high-dose patients (p>0.99). Sixteen patients received a second cycle of ibuprofen, and the ductus closed in 50% after low-dose and in 60% after high-dose therapy (p>0.99). Seven patients required surgery for ductus closure, 13.6% in the low-dose group and 3% in the high-dose group (p=0.22). Thirty-nine patients developed bronchopulmonary dysplasia, 50% in the low-dose group and 51.5% in the high-dose group (p>0.99). Twenty-two (50%) low-dose patients died vs. 15 (45.5%) high-dose patients (p=0.86). CONCLUSIONS There was no difference in closure of the ductus arteriosus or occurrence of adverse effects between the two dose regimens.

Abstract
Opinions are divided regarding the management of a persistently patent ductus arteriosus (PDA). Some of the adverse effects associated with a large hemodynamically significant duct, including prolonged ventilation, pulmonary hemorrhage, bronchopulmonary dysplasia (BPD), necrotizing enterocolitis (NEC), intraventricular hemorrhage (IVH), and mortality, indicate that active management of infants with large ductal shunts may sometimes be necessary. Indomethacin and ibuprofen are the two US FDA-approved cyclooxygenase (COX) inhibitors used for the closure of a ductus in preterm babies. Both these drugs are effective in 70-80% of extremely low birthweight infants. Treatment with COX inhibitors may be associated with renal impairment, gastrointestinal hemorrhage, NEC, and spontaneous intestinal perforation when given concurrently with steroids, as well as changes in cerebrovascular auto-regulation. Ibuprofen appears to be a better choice for PDA closure, with a better side effect profile and efficacy that equals that of indomethacin. However, long-term outcome studies of ibuprofen are lacking, and prophylactic ibuprofen is ineffective in decreasing severe IVH. The choice of one drug over the other also depends on local availability of both drugs and the intravenous or enteral preparation. The oral preparation of ibuprofen appears as effective as the intravenous preparation. The use of paracetamol to close a hemodynamically significant PDA has increased in recent years. Paracetamol also decreases prostacyclin synthesis; however, unlike COX inhibitors, it does not have a peripheral vaso-constrictive effect and can be given to infants with contraindications to non-steroidal anti-inflammatory drugs. It appears to have similar efficacy based on limited data available from randomized trials. Until more data are available on efficacy, safety, and long-term outcomes, it cannot be recommended as the first choice.

Abstract
Patent ductus arteriosus (PDA) is a common clinical condition in preterm infants which is inversely related to birth weight and gestational age. Cyclooxygenase inhibitors such as indomethacin and ibuprofen which block the prostaglandin conversion from arachidonic acid are the most commonly used drugs for ductal closure. This review focuses on the safety and efficacy oral medications in the management of PDA in preterm infants. Ibuprofen seems to be the first choice due to its higher safety profile, as it is associated with fewer gastrointestinal and renal side effects when compared to indomethacin. PDA closure rates are better with oral than with intravenous ibuprofen probably due to the pharmacokinetic of the drug. However, these medications were reported to be associated with several adverse including transient renal failure, gastrointestinal bleeding and perforation, hyperbilirubinemia and platelet dysfunction. Paracetamol seems be an alternative to PDA therapy with lower adverse events and side effects.

Abstract
The kidney is one of the key organs in clearing foreign compounds. The effects of drugs on the developing kidney are relatively unknown. We studied the direct effect of furosemide, hydrochlorothiazide, ibuprofen, and indomethacin on kidney development in an ex vivo embryonic kidney model. At embryonic day 13, metanephroi were dissected from mice and cultured in control media or media supplemented with various clinically relevant concentrations of drugs. The ureteric tree was visualized by whole-mount staining and branching was evaluated by counting. Additionally, gene expression levels of Wt1, Sox9, Bmp7, Fgf8, and Gdnf were investigated. No distinct differences were noted on either ureteric tip development or gene expression analysis for each drug after 24 hr of exposure. Even though short-term exposure to clinically relevant concentrations seems not to disturb renal development, future research is needed to study prolonged or repeated exposures.

Abstract
BACKGROUND Ibuprofen (IBU) has proved as effective as indomethacin in the pharmacological closure of hemodynamically significant patent ductus arteriosus (HsPDA), with an efficacy inversely related to gestational age (57-89%). OBJECTIVE This study aimed to establish whether continuous infusions of IBU could be more effective in very low birth weight infants with no additional adverse effects and reduce the need for surgical ligation. METHODS A prospective, randomized, double-dummy study was conducted on 112 very low birth weight infants (mean gestational age 27.2 weeks, SD 2; birth weight 1,019 g, SD 330) with HsPDA, 56 of whom were given IBU in conventional 15-min intermittent boluses, while the other 56 were administered IBU as a 24-hour continuous infusion, both at standard doses (10/5/5 mg/kg). Extensive echocardiography was performed before and after treatment, and adverse effects were monitored. RESULTS Pharmacological PDA closure was achieved after 1 or 2 IBU courses in 36 of 56 infants (64.3%) after bolus administration and in 46 of 55 (83.6%) after continuous infusion (p = 0.020), and in 9 of 26 (34.6%) and 24 of 30 (80.0%), respectively, in the infants with a gestational age of 23-27 weeks (p = 0.006). Sustained pharmacological closure was observed in 38 of 56 infants (67.9%) after bolus IBU and in 47 of 55 (85.5%) after continuous infusion (p = 0.029). Surgical ligation was used less after continuous infusion than after bolus IBU (5.5 vs. 19.6%; p = 0.024). The continuous infusion group had fewer symptoms of necrotizing enterocolitis (NEC), especially in the more preterm infants, while other neonatal morbidity and mortality rates were similar. CONCLUSION Continuous IBU infusion is more effective than standard boluses for sustained closure of HsPDA, with fewer NEC symptoms and less need for surgical ligation in very low birth weight infants.

Patent ductus arteriosus in preterm infants: do we have the right answers? BIOMED RESEARCH INTERNATIONAL 2013; 2013:676192.

Abstract
Patent ductus arteriosus (PDA) is a common clinical condition in preterm infants. Preterm newborns with PDA are at greater risk for several morbidities, including higher rates of bronchopulmonary dysplasia (BPD), decreased perfusion of vital organs, and mortality. Therefore, cyclooxygenase (COX) inhibitors and surgical interventions for ligation of PDA are widely used. However, these interventions were reported to be associated with side effects. In the absence of clear restricted rules for application of these interventions, different strategies are adopted by neonatologists. Three different approaches have been investigated including prophylactic treatment shortly after birth irrespective of the state of PDA, presymptomatic treatment using echocardiography at variable postnatal ages to select infants for treatment prior to the duct becoming clinically significant, and symptomatic treatment once PDA becomes clinically apparent or hemodynamically significant. Future appropriately designed randomized controlled trials (RCTs) to refine selection of patients for medical and surgical treatments should be conducted. Waiting for new evidence, it seems wise to employ available clinical and echocardiographic parameters of a hemodynamically significant (HS) PDA to select patients who are candidates for medical treatment. Surgical ligation of PDA could be used as a back-up tool for those patients who failed medical treatment and continued to have hemodynamic compromise.

Abstract
AIM The aim of this study was to explore the effects of early oral ibuprofen administration on the incidence of hemodynamically significant patent ductus arteriosus (hsPDA) and define the association between serum ibuprofen levels and ductal closure. METHOD Preterm infants with a gestational age of <28 weeks and/or birth weight of <1,000 g were randomized either to the intervention (ibuprofen prophylaxis) or control group. The intervention group received oral ibuprofen 10 mg/kg within 12-24 h after birth followed by 5 mg/kg at 24 and 48 h. Serum ibuprofen levels after the treatment were analyzed in the intervention group, and the incidence of hsPDA and complication rates were compared between two groups. RESULTS Nineteen infants who received one course (three doses) of prophylactic ibuprofen in the intervention group and 17 infants in the control group who underwent an echocardiographic examination on the fourth day of life were analyzed. hsPDA was observed in five (26 %) infants in the intervention group and ten (58 %) infants in the control group (p = 0.09). In the intervention group two infants experienced gastrointestinal bleeding two infants had spontaneous intestinal perforation, and two infants developed acute kidney failure. Mean serum ibuprofen level was 28.7 ± 16.9 mg/L in the intervention group, and there was no correlation between ibuprofen level obtained on the fourth day and ductal closure. CONCLUSION Oral ibuprofen prophylaxis reduces the rates of hsPDA even it is not statistically significant. The ductal closure rate did not correlate with serum ibuprofen levels. Due to high prevalence of adverse events observed, our data do not support the use of oral ibuprofen for prophylaxis of hsPDA.

Abstract
Indomethacin and ibuprofen are potent inhibitors of prostaglandin synthesis. Neonates have been exposed to these compounds for more than 3 decades. Indomethacin is commonly used to prevent intraventricular hemorrhage (IVH), and both drugs are prescribed for the treatment or prevention of patent ductus arteriosus (PDA). This review examines the basis for indomethacin and ibuprofen use in the neonatal intensive care population. Despite the call for restrained use of each drug, the most immature infants are likely to need pharmacologic approaches to reduce high-grade IVH, avoid the need for PDA ligation, and preserve the opportunity for an optimal outcome.

Abstract
Our aim was to assess the hypothesis that a high-dose regimen of ibuprofen is more effective than the standard-dose regimen in closing patent ductus arteriosus (PDA) without increasing adverse effects. Infants of gestational age <29 weeks, with respiratory distress syndrome (RDS) and echocardiographic evidence of significant PDA at 12-24 h of life, were randomized to receive a standard (10-5-5 mg/kg/day) or high-dose (20-10-10 mg/kg/day) course of ibuprofen. We studied 70 infants, 35 of whom received the standard dose of ibuprofen and the other 35 the high dose. Of the infants treated with the standard-dose regimen, 37% had persistent PDA as compared with 14% of those treated with the high-dose regimen (P = 0.03). No differences in the occurrence of adverse effects were observed between the two groups. The high-dose ibuprofen regimen is more effective than the standard-dose regimen in closing PDA in preterm infants <29 weeks of gestation without increasing the adverse effect rate.

Abstract
BACKGROUND Sometimes it might not be possible to conduct a pharmacokinetic (PK) study in neonates and infants. Under these circumstances, one would like to predict PK parameters in this age group. Because drug clearance is the most important PK parameter, the objective of this study was to describe an allometric method to predict drug clearance in children ≤3 months. METHODS In total, 43 drugs (107 observations) were randomly selected for this study. The age of the children ranged from 0 to 1 year. Children were divided into two groups: ≤3 months and ≥3 months to 1 year. Drug clearance (CL) in children was predicted using the following equation: CL in the child=adult CL×(weight of the child/70)(0.75 or 1.0 or 1.2). RESULTS The results of the study indicated that the exponent 1.2 performs better in the prediction of drug clearance than exponent 1.0 or 0.75 for children ≤3 months. By contrast, exponent 1.0 provided better prediction for children ≥3 months to 1 year than exponent 1.2. Exponent 0.75 provided the worst results leading to substantial prediction error in children 0-1 year (in many instances more than 1000% prediction error). CONCLUSIONS Overall, it appears that exponent 1.2 is the best method out of three methods for reasonably accurate prediction of drug clearance in children ≤3 months old. However, exponent 1.2 will underpredict drug clearance in children older than 3 months. The suggested approach could be used to support the choice of the initial dose in clinical trials for children ≤3 months old.

Abstract
Patent ductus arteriosus (PDA) is one of the most common problems in the care of premature infants, especially the extremely premature. There is no real consensus regarding the diagnostic criteria or treatment of a hemodynamically significant PDA. Its diagnosis, assessment, and treatment still remain challenges. Therefore, we investigated clinical practices in French tertiary neonatology centers regarding the management of PDA to compare their similarities and differences. We sent a questionnaire by email to the PDA specialist in every French tertiary neonatal intensive care unit. It contained 27 items regarding the unit's structure, method of diagnosing PDA, and treatment choices. The completed questionnaire were returned via email and analyzed blindly. The questionnaire response rate was 87.5%, which allowed us to draw some conclusions regarding French clinical practices in the care of neonates with PDA. Although the diagnostic criteria are quite similar, the therapeutic practices are rather different across neonatal care units. We highlight the great variability in French clinical practices when it comes to treating PDA and underscore the necessity for harmonization of these practices, which could be achieved using multicenter, randomized studies to identify the advantages of one approach compared with another.

Abstract
AIM To evaluate the effect of ibuprofen on bilirubin-albumin binding affinity and unbound bilirubin in premature infants. STUDY DESIGN A prospective study with subjects serving as their own controls was performed on <30 weeks' gestational age infants with unconjugated hyperbilirubinemia and who received ibuprofen for patent ductus arteriosus. Infants with congenital malformation, TORCH infections, and conjugated hyperbilirubinemia were excluded. Total serum bilirubin (TSB) and unbound bilirubin (modified peroxidase test) were measured prior to (baseline) and after (follow-up) initiation of ibuprofen. The bilirubin/albumin equilibrium association binding constant was calculated using albumin, TSB, and unbound bilirubin. RESULTS Ten infants were studied. The mean TSB between baseline (5.9±1.7 mg/dL) was higher than that at follow-up [4.9±1.7 mg/dL]. Mean unbound bilirubin at baseline (0.75±0.65 μg/dL) was similar to that at follow-up (0.63±0.46 μg/dL). No difference existed between mean baseline binding constant (49±50 L/μmol) and that at follow-up (44±36 L/μmol). The ratio of unbound bilirubin with and without ibuprofen, index of displacing effect, was 0.88 (95% CI 0.63-1.14). CONCLUSIONS Ibuprofen may not be associated with bilirubin displacing effect in relatively stable premature infants with mild to moderate unconjugated hyperbilirubinemia.

Abstract
BACKGROUND Patent ductus arteriosus (PDA) in extremely preterm infants remains a challenging condition with conflicting treatment strategies. Ibuprofen is currently used to treat PDA with ductal closure failure rate up to 40%. We test the hypothesis that cytochrome P450 CYP2C8/2C9 polymorphisms may predict ibuprofen response. METHODOLOGY/PRINCIPAL FINDINGS We studied extremely preterm neonates with haemodynamically significant PDA and treated with ibuprofen. One or two variant CYP2C8 and/or 2C9 alleles were found in 17% of the population, most of them were from Caucasian ethnicity (67-74%). Response to ibuprofen and clinical course of infants carrying variants CYP2C8 and CYP2C9 were similar. Comparing infants with wild type or variant CYP2C8 and CYP2C9 genotypes, response rate to ibuprofen was significantly higher in wild type than in mutated carriers in univariate analysis (73% versus 52%, p = 0.04). Comparing responders (ductus closure; n = 75) and non-responders (surgical ligation; n = 36), the only two factors significantly associated with the response to ibuprofen using multivariate analysis were higher gestational age and non Caucasian ethnicity but not CYP2C polymorphism. CONCLUSIONS CYP2C polymorphism was not associated with PDA response to ibuprofen and this factor appears not appropriate to optimize the ductal closure rate by modulating ibuprofen dosing strategy. This study points out the role for ethnicity in the interindividual variability of response to ibuprofen in extremely preterm infants.

Abstract
Ibuprofen binds to plasma albumin and could interfere with the binding of bilirubin in jaundiced newborn infants. Most clinical studies have not shown increased concentrations of unbound bilirubin (UB) in plasma from infants treated with ibuprofen for a patent ductus arteriosus. However, studies in vitro have not been equally conclusive. Plasma were obtained from routine samples from jaundiced newborn infants and pooled. Total and UB were measured with the peroxidase method after addition of ibuprofen or sulfisoxazole as a known bilirubin displacer. Final ibuprofen concentrations varied from 0.43 to 2.6 mM. Bilirubin concentrations were varied from 176 to 708 microM by adding bilirubin to plasma samples. Ibuprofen caused a linear increase in UB up to +54% at a concentration of 1.8 mM, compared with an increase of 87% by sulfisoxazole (1.32 mM). A double reciprocal plot of molar concentrations of bound versus UB at bilirubin concentrations ranging from 176 to 708 microM showed a competitive displacement of bilirubin by ibuprofen. The data indicate that ibuprofen is a competitive displacer of bilirubin in vitro. Ibuprofen should be used with caution in premature infants with a significant hyperbilirubinemia.

Effect of ibuprofen on bilirubin-albumin binding in vitro at concentrations observed during treatment of patent ductus arteriosus. Early Hum Dev 2010; 86:315-7.

Abstract
BACKGROUND In vitro studies have shown that ibuprofen (IBU) may interfere with bilirubin-albumin binding at concentrations of 100 microg/mL and above. OBJECTIVES The present study evaluates the in vitro bilirubin displacement over the range of IBU plasma concentrations observed in vivo during curative treatment of patent ductus arteriosus in preterm infants. METHODS Considering that individual plasma concentrations obtained during the clinical development of IBU in preterm infants were ranging between 10 and 70 microg/mL and exceptionally above 100 microg/mL, we used the modified peroxidase method to determine total and unbound bilirubin concentrations without IBU and with IBU over this specific concentration range. RESULTS Total bilirubin and albumin concentrations were respectively 6.6 mg/dL and 2.87 g/dL in pooled newborn plasma. No displacement of bilirubin from its albumin binding sites by IBU was observed over a range of concentrations from 10 to 100 microg/mL. Only a concentration of 200 microg/mL significantly increased the unbound bilirubin by 1.5-fold (p=0.0008). CONCLUSIONS This in vitro study confirms displacement of bilirubin by a high IBU concentration of 200 microg/mL, however it retrieves no significant displacement over a range of concentrations up to and including 100 microg/mL, i.e. within the range of in vivo concentrations at the recommended dose regimen.

Abstract
OBJECTIVE The aim of this study was to investigate whether ibuprofen exposure was associated with increased hyperbilirubinemia in preterm infants. METHODS Since 2000, ibuprofen has been administered to all infants at <30 weeks of gestation who are admitted to our unit, to prevent patent ductus arteriosus. We retrospectively compared data for 418 infants subjected to ibuprofen prophylaxis (2000-2007) and 288 infants not exposed to ibuprofen (1993-1999). RESULTS The ibuprofen group had a significantly higher peak total serum bilirubin level (9.0 +/- 2.5 mg/dL vs 7.3 +/- 3.3 mg/dL), more need for phototherapy (398 infants [95%] vs 254 infants [87.6%]), and a longer phototherapy duration (94.3 +/- 43.6 hours vs 87.2 +/- 38.6 hours). Groups did not differ with respect to gestational age, birth weight, gender ratio, glucose-6-phosphate dehydrogenase deficiency incidence, or hypoalbuminemia (<2.5 g/dL) incidence. Hemolytic isoimmunization was diagnosed with similar incidences (no-ibuprofen group: 7 of 288 infants; ibuprofen group: 8 of 418 infants). The rates of exchange-transfusion also were similar between the groups (no-ibuprofen group: 14 infants [4.8%]; ibuprofen group: 19 infants [4.5%]). CONCLUSIONS Ibuprofen administration was associated with higher peak total serum bilirubin levels, and the more-pronounced hyperbilirubinemia led to longer phototherapy. The potential role of competition between ibuprofen and bilirubin in the hepatic glucuronidation pathway is discussed.

Abstract
Premature infants are at risk for bilirubin-associated brain damage. In cell cultures bilirubin causes neuronal apoptosis and necrosis. Ibuprofen is used to close the ductus arteriosus, and is often given when hyperbilirubinemia is at its maximum. Ibuprofen is known to interfere with bilirubin-albumin binding. We hypothesized that bilirubin toxicity to cultured rat embryonic cortical neurons is augmented by coincubation with ibuprofen. Incubation with ibuprofen above a concentration of 125 microg/mL reduced cell viability, measured by methylthiazole tetrazolium reduction, to 68% of controls (p < 0.05). Lactate dehydrogenase (LDH) release increased from 29 to 38% (p < 0.01). The vehicle solution did not affect cell viability. Coincubation with 10 microM unconjugated bilirubin (UCB)/human serum albumin in a molar ratio of 3:1 and 250 microg/mL ibuprofen caused additional loss of cell viability and increased LDH release (p < 0.01), DNA fragmentation, and activated caspase-3. Preincubation with the pan-caspase inhibitor z-val-ala-asp-fluoromethyl ketone abolished ibuprofen- and UCB-induced DNA fragmentation. The study demonstrates that bilirubin in low concentration of 10 microM reduces neuron viability and ibuprofen increases this effect. Apoptosis is the underlying cell death mechanism.

Abstract
AbstractDosing pediatric drugs available on pharmaceutical markets of analgesic, antifebrile and anti-inflammatory activity to children up to 3 years of age is not precise and frequently causes problems. The aim of the study was to work out a pediatric teat form of a drug with sodium ibuprofen and to determine the effect of sorbitol content on pharmaceutical availability of the therapeutic agent. Three variants of tablets containing 50 mg of sodium ibuprofen differing in the percentage content of sorbitol (from 37% - batch I to 79% - batch III) were produced. Quality tests of the produced forms of drugs (PPVI) were performed and the tests of therapeutic agent pharmaceutical availability by spatula method and by a method with a teat. Tablets of all batches had a smooth surface and same shape. The content of the therapeutic agent was within the limit of 95-105% of the declared value. The highest value of Q coefficient in the release test by pharmacopeal method and the shortest disintegration time (12 minutes) were obtained for tablets with 79% content of sorbitol. In conclusion, teat tablets with sodium ibuprofen of the highest sorbitol content (79%) demonstrated the expected physicochemical parameters and high pharmaceutical availability.

Abstract
OBJECTIVE Ibuprofen might have advantages over indomethacin, when used to effectuate closure of a neonate's patent ductus arteriosus (PDA). Several previous studies indicate that platelet plug formation is impaired after administration of indomethacin, but it is not clear whether a similar impairment occurs following ibuprofen dosing. STUDY DESIGN We performed template bleeding times and PFA-100 tests (platelet function analyzer) on 20 neonates who had a PDA, before and again at various preset intervals following ibuprofen dosing. RESULT Patients ranged from 23 to 40 weeks gestation and weighed 511 to 2566 g. Their first dose of ibuprofen was administered at 72 h (18 to 363 h) after birth (median, range). None of the subjects had clinical bleeding problems noted during the days they received ibuprofen dosing. The template bleeding times before dosing ranged from 135 to 450 s. Repeat tests were performed in groups of four, at 2 h, 4 to 6 h, 12 to 18 h, 24 h after the first dose, and at 2 h after the third dose of ibuprofen. No changes in bleeding times were detected. (P=0.299) A PFA-100 time was performed on all 20 patients before and again after the ibuprofen administration. However, 3 of the 40 tests were unsuccessful, because of microclots in the blood sample (n=1) or failure of the analyzer for an unspecified reason (n=2). Before the dosing the PFA-100 time ranged from 52 to 300 s. A paired t-test showed a slight but statistically significant lengthening in PFA-100 time after the ibuprofen administration (P=0.019). The correlation between the bleeding time and the PFA-100 was poor (R(2)=0.212, P=0.576). CONCLUSION On the basis of our present studies, we speculate that ibuprofen lysine administration to neonates with a PDA, when used according to the manufacturer's recommendations, has little adverse effect on platelet plug formation. This information might be a factor to consider when deciding whether to select indomethacin or ibuprofen for PDA closure.

Abstract
AIM To determine whether ibuprofen use in VLBW infants is associated with increased serum bilirubin levels and impaired neurodevelopmental outcome at 2 years of age compared to indomethacin. METHODS We retrospectively evaluated bilirubin data and outcome parameters of 178 VLBW infants treated with COX inhibitors for a haemodynamically relevant patent ductus arteriosus (PDA) between 1998 and 2003 in a single institution. In our department ibuprofen replaced indomethacin for PDA treatment in 2001, while clinical and echocardiographic criteria for the indication of PDA invention have remained unchanged. RESULTS Ibuprofen and indomethacin therapy groups did not differ in their baseline clinical profile. Peak serum bilirubin concentration was 10.2 mg/dL in the ibuprofen group and 8.6 mg/dL in the indomethacin group (p < 0.01), while phototherapy duration did not differ. At 2 years of age neurodevelopmental outcome was similar in both groups. In a single case analysis, four cases of adverse neurodevelopmental outcome despite inconspicuous clinical course were identified in the ibuprofen group. CONCLUSION In VLBW infants with PDA, ibuprofen treatment was associated with higher bilirubin levels than indomethacin.

Abstract
BACKGROUND We conducted a prospective, randomized, single-masked pilot study with the principal aim of comparing efficacy and tolerance between oral and intravenous ibuprofen in early closure of patent ductus arteriosus in very low birth weight infants. The possibility of ductal closure with only 1 or 2 doses of treatment was a secondary objective. MATERIAL AND METHODS Sixty-four very low birth weight patients with echocardiographically confirmed patent ductus arteriosus and respiratory distress were studied. The patients were randomly assigned to receive either oral (group O, n=32) or intravenous (group I, n=32) ibuprofen starting on the third day of life. After the first dose of treatment in both groups, echocardiographic evaluation was performed to determine the need for a second or third dose. The rate of ductal closure, adverse effects, complications, and the patient's clinical course were recorded. RESULTS In each group, 24 (75%) patients were born after 28 weeks' gestation. The rate of ductal closure tended to increase in group O (84.3% vs 62.5%). Closure of the ductus was obtained after 1 or 2 doses of treatment in 19 (70.3%) of 27 patients in group O and 14 (70%) of 20 patients in group I. The adverse effects were increased in group I (31.2% vs 9.3%). There were no significant differences with respect to complications during the stay. Adverse effects were significantly fewer when closure was achieved after an incomplete course of treatment (23.1% vs 76.9%). CONCLUSIONS In very low birth weight infants, the rate of early ductal closure with oral ibuprofen is at least as good as with the intravenous route. Ductal closure may be obtained with an incomplete course of ibuprofen. Oral ibuprofen is associated with fewer adverse effects. However, a larger sample is needed for more definitive conclusions.

Abstract
OBJECTIVE To demonstrate, in vitro, the influence of increasing ibuprofen (IBU) concentration on bilirubin-albumin (B-A) binding. STUDY DESIGN The influence of IBU on B-A binding was measured by saturation index and horseradish peroxidase assays. B-A solutions were prepared at B:A ratios of 0.5, 1.0, 1.5 and 2.0 and bilirubin concentrations of 5 and 10 mg per 100 ml. Drug concentrations used were 142.5, 200 and 285 mg l(-1) for IBU and 100 and 200 mg l(-1) for acetyl salicylic acid (ASA). Similar tests were performed on premature newborn sera with bilirubin concentrations of 5 to 10 mg per 100 ml. RESULT By the saturation index test, significant displacement of bilirubin from albumin with IBU was demonstrated only on B-A solution with high B:A ratio of 2.0 and IBU concentration of 285 mg l(-1) and was less as compared to ASA. No displacement was observed in the sera of jaundiced neonates. By the horseradish peroxidase assay using B-A solutions, free bilirubin was significantly increased at (1) increasing concentrations of bilirubin in solution and (2) increasing B:A ratios in a solution containing 5 mg per 100 ml of bilirubin. In the sera of jaundiced neonates, significantly higher free bilirubin concentrations were observed when IBU was added to serum with bilirubin concentration of 10 mg per 100 ml as compared to 5 mg per 100 ml (0.062+/-0.004 versus 0.026+/-0.005, P<0.001 by Student's t-test). CONCLUSION Displacement of bilirubin was demonstrated only at high IBU concentration and high B:A ratio. However, free bilirubin levels were not shown to increase with increasing IBU concentration.

Abstract
WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT Ibuprofen is a nonsteroidal anti-inflammatory agent that induces closure of the patent ductus arteriosus in neonates. Few studies of ibuprofen pharmacokinetics have been performed and were limited to small groups of preterm infants, showing a large intersubject variability and an increase in clearance with either postnatal or gestational age. WHAT THIS STUDY ADDS A population pharmacokinetic study was performed on 66 neonates to characterize the concentration-time courses of ibuprofen. Ibuprofen clearance significantly increased from postnatal age day 1 to day 8, but not with gestational age. A relationship was shown between ibuprofen area under the curve (AUC) and patent ductus arteriosus closure rate, and an effective threshold AUC was evidenced. Dosing schemes were proposed as a function of postnatal age, to achieve this AUC and to improve the efficacy of treatment for patent ductus arteriosus in neonates. AIMS To describe ibuprofen pharmacokinetics in preterm neonates with patent ductus arteriosus (PDA) and to establish relationships between doses, plasma concentrations and ibuprofen efficacy and safety. METHODS Sixty-six neonates were treated with median daily doses of 10, 5 and 5 mg kg(-1) of ibuprofen-lysine by intravenous infusion on 3 consecutive days. A population pharmacokinetic model was developed with NONMEM. Bayesian individual pharmacokinetic estimates were used to calculate areas under the curve (AUC) and to simulate doses. A logistic regression was performed on PDA closure. RESULTS Ibuprofen pharmacokinetics were described by a one-compartment model with linear elimination. Mean population pharmacokinetic estimates with corresponding intersubject variabilities (%) were: elimination clearance CL = 9.49 ml h(-1) (62%) and volume of distribution V = 375 ml (72%). Ibuprofen CL significantly increased with postnatal age (PNA): CL = 9.49*(PNA/96.3)(1.49). AUC after the first dose (AUC1D), the sum of AUC after the three doses (AUC3D) and gestational age were significantly higher in 57 neonates with closing PDA than in nine neonates without PDA closure (P = 0.02). PDA closure was observed in 50% of the neonates when AUC1D < 600 mg l(-1) h (or AUC3D < 900 mg l(-1) h) and in 91% when AUC1D > 600 mg l(-1) h (or AUC3D > 900 mg l(-1) h) (P = 0.006). No correlation between AUC and side-effects could be demonstrated. CONCLUSIONS To achieve these optimal AUCs, irrespective of gestational age, three administrations at 24 h intervals are recommended of 10, 5, 5 mg kg(-1) for neonates younger than 70 h, 14, 7, 7 mg kg(-1) for neonates between 70 and 108 h and 18, 9, 9 mg kg(-1) for neonates between 108 and 180 h.

Abstract
Patent ductus arteriosus (PDA) is a common complication in preterm infants. An intravenous (IV) cyclooxygenase (COX) inhibitor is the pharmacotherapy of choice. Concerns over adverse effects associated with the traditional treatment, IV indomethacin, have led to the investigation of other COX inhibitors to assist closure of PDA. IV ibuprofen lysine is a COX inhibitor that demonstrates similar efficacy to indomethacin with few adverse effects. In addition, IV ibuprofen lysine does not cause reductions in cerebral, renal, and mesenteric blood flow that can be seen with indomethacin, and thus ibuprofen therapy is not associated with reduced renal function. Ibuprofen is primarily metabolized by cytochrome P450 (CYP) 2C9. The immaturity of neonatal biotransformation pathways has a pronounced effect on the pharmacokinetic parameters of ibuprofen, particularly because CYP2C9 enzyme activity is known to be very low at birth and to increase rapidly over the first several days of life. Ibuprofen is highly bound to albumin, raising concern that ibuprofen may displace bilirubin and subsequently increase free bilirubin concentrations. However, the ibuprofen concentrations achieved with approved dosing with IV ibuprofen lysine are lower than those expected to result in displacement of bilirubin and related adverse effects. Factors such as gestational age and CYP2C9 polymorphism may affect ibuprofen metabolism and therefore optimal dosing, but further clinical investigation is needed in these areas. Other areas for future investigation include prolonged dosing regimens, prophylactic administration, and alternate indications. At the approved dose, IV ibuprofen lysine is a safe, effective pharmacologic agent to promote closure of PDAs in preterm infants.

Abstract
When medical management is warranted for closure of a persistent patent ductus arteriosus (PDA) in premature infants, treatment with a cyclooxygenase (COX) inhibitor is indicated. Indomethacin, available since 1976, has been the conventional pharmacologic treatment for PDA, but its use is associated with vasoconstrictive effects that impair renal, mesenteric and cerebral blood flow. Intravenous (IV) ibuprofen lysine, approved in the United States in 2006, has less severe vasoconstrictive effects on these vital organs than IV indomethacin. Clinical trials have shown both of these COX inhibitors to be equally effective in closing the PDA in approximately 70%-80% of treated infants, with less vasoconstrictive and adverse renal effects occurring with IV ibuprofen lysine.1,2 Several clinical considerations are important in the process of medical decision-making when faced with the need for PDA treatment with one of these pharmacologic agents in the premature infant. This paper focuses on these clinical considerations, including cerebral, renal and mesenteric blood flow, renal function, pulmonary effects, protein-binding capacity as it relates to hyperbilirubinemia, and platelet aggregation. No differences in chronic lung disease, pulmonary hypertension, hyperbilirubinemia and coagulopathy were observed in clinical trials when comparing these 2 COX inhibitors; however, significant differences have been observed in arterial blood flow to the cerebral, renal and mesenteric organs, suggesting that IV ibuprofen lysine may be the more favorable agent.

Abstract
The non-steroidal anti-inflammatory drugs (NSAIDs) and acetaminophen (paracetamol) are the most common analgesic drugs used in neonates and infants despite limited pharmacodynamic data. Both drugs act through inhibition of cyclooxygenase enzymes. Neonatal acetaminophen clearance is reduced in premature neonates (0.7 L h(-1) x 70 kg(-1)) and increases to 5 L h(-1) x 70 kg(-1) at term (40% adult rates); adult rates are reached within the first year of life; NSAID clearance follows similar trends. Volume of distribution is increased in the neonatal period. Dosing of both drug groups is tempered by concerns about toxicity. Acetaminophen hepatotoxicity is less common in neonates than in older children and adults, possibly due to reduced oxidative enzyme activity (e.g. CYP 2E1). Data concerning NSAID adverse effects in the neonatal period are few. Renal function is reduced 20% after NSAID use for patent ductus arteriosus closure in premature neonates and there is no increased frequency of intraventricular haemorrhage. No significant difference in the change in cerebral blood volume, change in cerebral blood flow, or tissue oxygenation index was found between administration of ibuprofen or placebo in neonates. Future studies should define concentration-response relationships for these drugs that are age and pathology specific.

Abstract
Growth and development are two linked processes that distinguish children from adults. The use of size as the primary covariate during pharmacokinetic (PK) analyses allows exploration of the effects of age. Allometric scaling models have assisted understanding of the developmental clearance changes in common analgesic drugs such as paracetamol, morphine, tramadol and local anaesthetics agents. Single nucleotide polymorphisms (pharmacogenomics [PG]) and their impact on hepatic drug metabolism for opioids, tramadol, non-steroidal anti-inflammatory drugs (NSAIDs) and drug receptor responses are increasingly reported. Altered chemical structure or formulations of common analgesics alter pharmacodynamic (PD) effects enhancing safety and efficacy for NSAIDs by stereoselectivity and the addition of nitric oxide, for intravenous paracetamol by formulation and structural difference from propacetamol and for local anaesthetics through stereoselectivity. This article focuses upon recent data for analgesics used in paediatric pain management including paracetamol, NSAIDs, morphine, tramadol, amide local anaesthetics and ketamine. It centres on PK and clinical studies in neonates, infants and children. PG studies are acknowledged as potentially allowing individual drug therapy tailoring through a decrease in between-patient population variability, although the impact of PG in the very young is less certain. There are few data describing age-related PD changes in children despite recognition that the number, affinity and type of receptors or the availability of natural ligands changes with age.
