Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in infants, children, and adolescents worldwide; however, despite sufficient evidence of the beneficial effects of NSAIDs in children and adolescents, there is a lack of comprehensive data in infants. The present review summarizes the current knowledge on the safety and efficacy of various NSAIDs used in infants for which data are available, and includes ibuprofen, dexibuprofen, ketoprofen, flurbiprofen, naproxen, diclofenac, ketorolac, indomethacin, niflumic acid, meloxicam, celecoxib, parecoxib, rofecoxib, acetylsalicylic acid, and nimesulide. The efficacy of NSAIDs has been documented for a variety of conditions, such as fever and pain. NSAIDs are also the main pillars of anti-inflammatory treatment, such as in pediatric inflammatory rheumatic diseases. Limited data are available on the safety of most NSAIDs in infants. Adverse drug reactions may be renal, gastrointestinal, hematological, or immunologic. Since NSAIDs are among the most frequently used drugs in the pediatric population, safety and efficacy studies can be performed as part of normal clinical routine, even in young infants. Available data sources, such as (electronic) medical records, should be used for safety and efficacy analyses. On a larger scale, existing data sources, e.g. adverse drug reaction programs/networks, spontaneous national reporting systems, and electronic medical records should be assessed with child-specific methods in order to detect safety signals pertinent to certain pediatric age groups or disease entities. To improve the safety of NSAIDs in infants, treatment needs to be initiated with the lowest age-appropriate or weight-based dose. Duration of treatment and amount of drug used should be regularly evaluated and maximum dose limits and other recommendations by the manufacturer or expert committees should be followed. Treatment for non-chronic conditions such as fever and acute (postoperative) pain should be kept as short as possible. Patients with chronic conditions should be regularly monitored for possible adverse effects of NSAIDs.

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
Objective: To evaluate the analgesic and antipyretic efficacy and safety of ibuprofen compared to acetaminophen in children and adults. Data Sources: Literature searches were performed using PubMed/MEDLINE (through August 2009) and EMBASE (through January 2008) and were restricted to the English language. In PubMed/MEDLINE, search terms used were ibuprofen, acetaminophen, paracetamol, clinical trials, and randomized controlled trials. EMBASE search terms included ibuprofen and acetaminophen, restricted to human and clinical trials. Study Selection And Data Extraction: All English-language articles identified from the data sources were reviewed. Multiple review articles were studied for any pertinent references and this yielded additional articles. Only articles that directly compared ibuprofen and acetaminophen were eligible for this review. Data Synthesis: Eighty-five studies that directly compared ibuprofen to acetaminophen were identified; 54 contained analgesic efficacy data, 35 contained antipyretic/temperature reduction data, and 66 contained safety data (some articles contained more than 1 type of data). Qualitative review of the literature revealed that, for the most part, ibuprofen was more efficacious than acetaminophen for the treatment of pain and fever in both pediatric and adult populations, and that these 2 drugs were equally safe. Meta-analyses on the subset of randomized clinical trial articles that reported sufficient quantitative information to calculate either an odds ratio (adverse event [AE]) or standardized mean difference (pain and fever) confirmed the qualitative results for adult (standardized mean difference [SMD] 0.69; 95% CI 0.57 to 0.81) and pediatric (SMD 0.28; 95% CI 0.10 to 0.46) pain at 2 hours postdose and pediatric fever (SMD 0.26; 95% CI 0.10 to 0.41) at 4 hours postdose. Conclusions regarding adult fever/temperature reduction could not be made due to a lack of evaluable data. The combined odds ratio for the proportion of adult subjects experiencing at least 1 AE slightly favored ibuprofen; however, the difference was not statistically significant (1.12; 95% CI 1.00 to 1.25). No significant difference between drugs in AE incidence was found for pediatric patients (0.82; 95% CI 0.60 to 1.12). Conclusions: Ibuprofen is as or more efficacious than acetaminophen for the treatment of pain and fever in adult and pediatric populations and is equally safe.

Abstract
OBJECTIVE To evaluate the antipyretic effects and safety of ibuprofen compared with acetaminophen in febrile children. DATA SOURCES Searches of MEDLINE (1966-November 2003) and EMBASE (1988-November 2003) were conducted using the terms ibuprofen and acetaminophen. Bibliographies of selected articles were reviewed. DATA SYNTHESIS Ibuprofen was significantly more effective than acetaminophen in reducing fever after a single dose. Ibuprofen was found to be more effective after 6 hours, but not after a longer period of time. Studies with multiple doses have also failed to show that one drug is better than the other. CONCLUSIONS The efficacy and effectiveness of acetaminophen and ibuprofen in their recommended dosages are similar, with slightly more beneficial effects shown with ibuprofen.

Abstract
Community health practitioners frequently prescribe or advise parents on antipyretic medications for children with fevers. This mini-review sets out to examine the evidence for the relative effectiveness of two of the most widely available and commonly used over-the-counter medicines - paracetamol and ibuprofen. A systematic literature search was undertaken to identify all studies comparing the effects of the two drugs. The Medline, Embase, Cinahl and RCN databases were searched. Eight randomized controlled trials that reported temperature differences at time-points between 1 and 6 hours after administration were identified. Statistical meta-analysis showed no clear benefit for one drug over another 1 hour after administration. However, by 6 hours after administration ibuprofen was clearly superior resulting in a mean temperature 0.58 degrees C lower than paracetamol. Both drugs appeared well tolerated and no evidence of difference in short-term adverse effects was observed. Both drugs are effective antipyretics but the longer action of ibuprofen may make it preferable in some circumstances.

Abstract
Fever is an important symptom of underlying disease condition and in general is considered harmful in pediatric age group as it may lead to febrile seizures, stupor, dehydration increase work of breathing, discomfort and tachycardia. The increase metabolic demands stress the patient with marginal cardiac and cerebral vascular supply. The hypothalamus controls the body temperature. The fever results due to resetting of the hypothalamus that occur from the prostaglandins produced by the pyrogens. Fever is treated variedly by the pediatricians. The physical therapy offers a simple and cost effective way of lowering the body temperature. The drugs as paracetamol, nimesulide and ibuprofen lower the temperature by inhibiting the prostaglandin synthesis. Paracetamol is considered the safest of all the antipyretic drugs. It is recommended that a combination of physical therapy such as tepid sponging and paracetamol is best way of controlling temperature.

Abstract
The antipyretic activity of ibuprofen in the Sparklets form was compared, in an equivalence study, with that of paracetamol in the same formulation. The study was conducted as a double-blind multicenter trial, with random allocation of the treatments. One hundred sixteen children of both sexes, aged 4.1 +/- 2.6 years, with a fever related to an infectious disease and a mean temperature of 39 degrees +/- 0.5 degrees C at the time of inclusion, were treated with single doses of either 10.3 +/- 1.9 mg/kg of ibuprofen or 9.8 +/- 1.9 mg/kg of paracetamol. The subjects' rectal temperature was regularly monitored for 6 hours. The statistical analysis of the results confirmed that ibuprofen and paracetamol are equivalent with respect to the following criteria (1) time elapsed between dosing and the lowest temperature: 3.61 +/- 1.34 hours for ibuprofen and 3.65 +/- 1.47 hours for paracetamol (95% confidence interval [CI] of the difference: -0.48; +0.56); (2) extent of the temperature decrease: 1.65 degrees C +/- 0.80 degrees C for ibuprofen and 1.50 degrees C +/- 0.61 degrees C for paracetamol, (95% CI of the difference: -0.41; +0.11); (3) rate of temperature decrease: 0.52 +/- 0.32 degrees C/hr for ibuprofen and 0.51 degrees C +/- 0.38 degrees C/hr for paracetamol (95% CI of the difference: -0.45; +0.55); (4) duration of temperature below 38.5 degrees C: 3.79 +/- 1.33 hours for ibuprofen and 3.84 +/- 1.22 hours for paracetamol (95% CI of the difference: -0.14; +0.12).

Abstract
Two hundred and twenty-four children aged 6 months to 5 years, with rectal temperatures greater than or equal to 30 degrees (104 degrees F), were randomly treated with sponging alone or with medication including a single oral dose of aspirin 15 mg/kg, or paracetamol 15 mg/kg, or ibuprofen 8 mg/kg. Twenty-three children were excluded from the final analysis because they did not complete the study. Demographic characteristics of the patients were found to be comparable in all groups. Rectal temperatures were recorded every 30 min for a 3 h period. During the first 30 min of intervention, sponging was found to be more effective than all of the three medications. After 60 min, the effects of each medication became superior to sponging with tepid water in reducing body temperature. Twenty-three children were excluded from the final analysis because they did not complete the study. Comparing the effect of the three different medications, it was seen that the antipyretic efficacy of aspirin and ibuprofen were significantly more than paracetamol 3 h after intervention (P < 0.05). For the management of fever over 39 degrees C, it is therefore recommended to give children an antipyretic drug, preferably ibuprofen, and at the same time to begin sponging to provide a rapid and sustained antipyresis

Abstract
Two hundred and nineteen children (boys: 56%, girls: 44%) were included in a randomized, double-blind, multicentre (4 centres) controlled trial designed to assess the efficacy and safety of ibuprofen (IBU) in the treatment of 1 to 6 year-old children with otoscopically proven acute otitis media (AOM), either unilateral or bilateral. They randomly received 10 mg/kg IBU (n = 71), or acetaminophen (PARA) (n = 73) or placebo (PLA) (n = 75), orally, tid, for 48 hours. All received oral cefaclor (Alfatil, Lilly, France) for seven days. They were evaluated before (D0) and at the end of treatment (D2). The main criterion of response was the aspect (landmarks and color) of the tympanic membrane assessed on a semi-quantitative scale from 0 to 6. Other criteria, assessed on semi-quantitative scales, included relief of pain (0 or 1), rectal temperature (0 to 2), and overall evaluation by parents of the improvement of quality of life on three items: appetite (0 to 2), sleep (0 to 2), and playing activity (0 to 2). The results at D2 were as follows: there was no significant difference between treatment groups as to the main criterion, but only a trend for IBU and PARA to do better than PLA but not for IBU to do better than PARA. From these data there is no argument to emphasize the utility of non-steroidal anti-inflammatory drugs (NSAIDs) in treating the inflammatory signs of the tympanic membrane in otitis. There was a statistically significant difference between treatment groups at D2 for pain, IBU being superior to PLA (P < 0.01): 7%, 10% and 25% of the children were still suffering at D2 in the IBU, PARA and PLA treatment groups, respectively. The difference between PARA and PLA for pain was not statistically significant. There was no significant difference between treatment groups for the other criteria. All treatments were well and equally tolerated. Although no significant difference was found between the treatment groups on the aspect of the tympanic membrane, the efficacy of IBU was evidenced on the relief of pain, the symptom that most disturbs the child.

Abstract
A double-blind, randomised, parallel group study has been done comparing the efficacy and tolerability of 7.5 mg/kg ibuprofen syrup (n = 77) and 10 mg.kg-1 acetaminophen syrup (n = 77) in 154 children (6 months to 5 years) with fever (> or = 38 degrees C) associated with infectious diseases and treated with antibiotic therapy. The area under the percentage reduction in temperature curve captured the net effect of each drug and provided the best estimate for comparison of efficacy during a defined period. Temperature evolution over time was not significantly different between the two groups. Nevertheless, the temperature reduction over the first 4 h of treatment (H0-H4) was significantly higher after ibuprofen (60%) than acetaminophen (45%). Both ibuprofen and acetaminophen were well tolerated. In conclusion, significant antipyretic activity, good tolerability and its availability as a syrup make ibuprofen an effective means of fever control in children.

Abstract
Ibuprofen was evaluated as an antipyretic agent in 178 children (aged 3 months to 12 years) to compare dosage (5 vs 10 mg/kg), establish absolute efficacy (with a placebo control group), determine relative efficacy (ibuprofen vs acetaminophen), evaluate maximum efficacy, and identify potential confounding variables. Ibuprofen 5 mg/kg was minimally effective in children less than 6 years of age who had an initial temperature of at least 38.8 degrees C (101.9 degrees F). Ibuprofen 10 mg/kg was more effective for febrile children. The area under the curve for temperature (or change in temperature) captured the net effect of each drug and provided the best estimate for efficacy comparison during a defined period. A linear correlation between initial temperature and measures of efficacy was observed. A twofold increase in efficacy was observed for children with an initial temperature less than 38.8 degrees C. A similar effect was noted for each treatment group. Age was also found to have confounding effects on antipyretic response. A complex interaction between antipyretic response, initial temperature, and age raises questions about the pharmacodynamics of the antipyretic response. We conclude that the most important variable in antipyretic study design is initial temperature. The influence of initial temperature on the magnitude of the response to an antipyretic drug is a previously unappreciated finding with potential impact on pharmacodynamic investigations of antipyretic medications. We describe this finding as nonlinear pharmacodynamics.

Abstract
A double blind trial was conducted to determine the dose of ibuprofen suspension, which is effective in reducing the body temperature. The principal measure of efficacy was a reduction in axillary temperature of 1 degree C or more three hours after dosing. A second objective of the trial was to compare the incidence and severity of side effects and the palatability of a range of ibuprofen doses. Ninety three children were included in the analysis. All four doses of ibuprofen studied (0.625 mg/kg-5 mg/kg) were associated with temperature reduction and only the lowest dose failed to satisfy the principal measure of efficacy. The influence of dose on the magnitude of the body temperature reduction was significant and the 5 mg/kg dose achieved the largest mean reduction in body temperature (2 degrees C). The tolerability and palatability of all doses studied were excellent. These findings suggest that ibuprofen is a good alternative to paracetamol as an antipyretic.

Abstract
Antiinflammatory therapy with ibuprofen has been proposed to retard the progression of lund disease in cystic fibrosis (CF). The pharmacokinetics and toxicity of ibuprofen were investigated in a randomized, double-blind, placebo-controlled, 3-month dose-escalation study in 19 children with CF, 6 to 12 years of age. The subjects received orally and twice daily 300 mg of drug during the first month, 400 mg in the second month, and 600 mg in the third month. Ibuprofen pharmacokinetics and evaluation for adverse effects were performed at the beginning and end of each month. The dose of ibuprofen was increased if peak plasma concentration (Cmax) was less than 50 micrograms/ml. To preserve the blind nature of the study, the dose in matched subjects taking placebo was also increased. The subjects randomly assigned to receive ibuprofen (n = 13) completed 26 months of treatment; placebo subjects (n = 5) completed 12 months. With dose escalation, Cmax and the area under the concentration-time curve from zero to infinity significantly increased (p less than 0.01). The pharmacokinetics of ibuprofen in 13 children with CF who received 13.4 +/- 4.1 mg/kg (mean +/- SD) were compared with those in four healthy children who received a similar dose. Peak plasma concentration (48 +/- 17 micrograms/ml) was decreased by 27% (p = 0.06), the area under the concentration-time curve (6.1 +/- 1.7 mg.min/ml) was decreased by 46% (p less than 0.001), apparent total clearance (2.3 +/- 0.6 ml/min.kg-1) was increased by 77% (p less than 0.01), and apparent volume of distribution during terminal phase (291 +/- 91 ml/kg) was increased by 84% (p = 0.01) in the children with CF. Time to Cmax (66 +/- 20 minutes) and elimination half-life (92 +/- 27 minutes) were not significantly different. No subjects were withdrawn from the study because of side effects. No adverse effects could be attributed to ibuprofen. Thus ibuprofen administration has no significant toxic effects, but Cmax will need to be monitored for effective dosing in patients with CF.

Abstract
Antipyretics, in particular acetaminophen, aspirin and ibuprofen, constitute the single most important class of drugs used therapeutically for an effect on body temperature. Hallucinogens exert prominent actions on the central nervous system, and it is not surprising that, like so many other centrally-acting agents, they too often affect temperature. This compilation primarily covers the considerable amount of data published from 1981 through 1985 on the interactions of these drugs and thermoregulation, but data from many earlier papers not included in a previous compilation are also tabulated. The effects of agents not classically considered as antipyretics on temperatures of febrile subjects are also covered. The information listed includes the species used, the route of administration and dose of drug, the environmental temperature at which experiments were performed, the number of tests, the direction and magnitude of change in body temperature and remarks on special conditions, such as age or brain lesions. Also indicated is the influence of other drugs, such as antagonists, on the response to the primary agent.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) have become the principal mode of therapy for rheumatic diseases and their use has continued to increase despite concern expressed recently regarding potential hazards (Figure 1). Prior to 1969, a limited number of NSAID drugs were available. Aspirin and indomethacin became the mainstay of treatment but tolerability, particularly gastric irritation, at doses necessary to control rheumatic symptoms limited the usefulness of these valuable agents. The pyrazolone, phenylbutazone, showed slightly better gastro-intestinal (GIT) tolerability but has since been associated with an increased risk of blood dyscrasiae and is now only available for restricted use in most countries. Ibuprofen was the first of a new breed of NSAIDs originally introduced into the United Kingdom in 1969. Chemically quite distinct from its forerunners it was the first of the propionic acid derivatives to be used in rheumatic practice. The propionics have since become the largest, single and most important group of NSAIDs accounting for 50% of NSAID prescriptions in the United Kingdom. It is estimated that over 100 million patients worldwide have received ibuprofen which is now available in over 100 countries throughout the world including all the major markets. Ibuprofen was developed directly as a result of the problems associated with the use of corticosteroids in the treatment of rheumatoid arthritis and also because of the gastro-intestinal irritation and general intolerability of the established NSAIDs, at that time. Ibuprofen was readily accepted because, unlike the previous drugs, its therapeutic efficacy was easily seen to outweigh the severity of its side-effects. Ibuprofen was the first new drug with the potency of aspirin but without its major disadvantages.
