Lenoir C, Rollason V, Desmeules JA, Samer CF. Influence of Inflammation on Cytochromes P450 Activity in Adults: A Systematic Review of the Literature. Front Pharmacol 2021; 12:733935. [PMID: 34867341 PMCID: PMC8637893 DOI: 10.3389/fphar.2021.733935] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 10/13/2021] [Indexed: 12/15/2022] Open
Abstract
Background: Available in-vitro and animal studies indicate that inflammation impacts cytochromes P450 (CYP) activity via multiple and complex transcriptional and post-transcriptional mechanisms, depending on the specific CYP isoforms and the nature of inflammation mediators. It is essential to review the current published data on the impact of inflammation on CYP activities in adults to support drug individualization based on comorbidities and diseases in clinical practice. Methods: This systematic review was conducted in PubMed through 7th January 2021 looking for articles that investigated the consequences of inflammation on CYP activities in adults. Information on the source of inflammation, victim drugs (and CYPs involved), effect of disease-drug interaction, number of subjects, and study design were extracted. Results: The search strategy identified 218 studies and case reports that met our inclusion criteria. These articles were divided into fourteen different sources of inflammation (such as infection, autoimmune diseases, cancer, therapies with immunomodulator…). The impact of inflammation on CYP activities appeared to be isoform-specific and dependent on the nature and severity of the underlying disease causing the inflammation. Some of these drug-disease interactions had a significant influence on drug pharmacokinetic parameters and on clinical management. For example, clozapine levels doubled with signs of toxicity during infections and the concentration ratio between clopidogrel's active metabolite and clopidogrel is 48-fold lower in critically ill patients. Infection and CYP3A were the most cited perpetrator of inflammation and the most studied CYP, respectively. Moreover, some data suggest that resolution of inflammation results in a return to baseline CYP activities. Conclusion: Convincing evidence shows that inflammation is a major factor to be taken into account in drug development and in clinical practice to avoid any efficacy or safety issues because inflammation modulates CYP activities and thus drug pharmacokinetics. The impact is different depending on the CYP isoform and the inflammatory disease considered. Moreover, resolution of inflammation appears to result in a normalization of CYP activity. However, some results are still equivocal and further investigations are thus needed.

Simultaneous determination of five alkaloids from Rauvolfia vomitoria in rat plasma by LC-MS/MS: Application to a comparative pharmacokinetic study in normal and type 2 diabetic rats. J Sep Sci 2021; 44:1391-1403. [PMID: 33470534 DOI: 10.1002/jssc.202000914] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 12/27/2020] [Accepted: 01/16/2021] [Indexed: 11/06/2022]
Abstract
Rauvolfia vomitoria is widely distributed in the tropical regions of Africa and Asia, and has been used in traditional folk medicine in China. Indole alkaloids were found to be major bioactive components, while the effects of diabetes mellitus on the pharmacokinetic parameters of the components have not been reflected in vivo. In this study, an efficient and sensitive liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous determination of five ingredients of R. vomitoria in rats. Detection was implemented in multiple-reaction-monitoring mode with an electrospray positive-ionization source. Validation parameters were all in accordance with the current criterion. The established method was effectively employed to compare the pharmacokinetic behaviors of five alkaloids (reserpine, yohimbine, ajmaline, ajmalicine, and serpentine) between normal and type 2 diabetic rats. The single-dose pharmacokinetic parameters of the five alkaloids were determined in normal and diabetic rats after oral administration of 100 and 200 mg/kg body weight. The results indicated that diabetes mellitus significantly altered the pharmacokinetic characteristics of yohimbine, ajmaline, and ajmalicine after oral administration in rats. This is an attempt to provide some evidence for clinicians that may serve as a guide for the use of antidiabetic medicine in clinical practice.

Abstract
Supplemental Digital Content is available in the text. Biochemical drug screening by liquid chromatography-tandem mass spectrometry in plasma is an accurate method for the quantification of plasma concentrations of antihypertensive medications in patients with hypertension. Trough concentrations could possibly be used as drug-specific cutoff values in the biochemical assessment of (non-)adherence. We performed a literature review and meta-analysis of pharmacokinetic studies to determine plasma trough concentrations of amlodipine, hydrochlorothiazide, and valsartan. PubMed was searched for pharmacokinetic studies up to September 2020. Eligible studies reported steady-state mean trough concentration and their variance. Pooled trough concentrations were estimated using a three-level random effects meta-analytic model. Moderator analyses were performed to explore sources of heterogeneity. One thousand three hundred eighteen potentially relevant articles were identified of which 45 were eligible for inclusion. The pooled mean trough concentration was 9.2 ng/mL (95% CI, 7.5–10.8) for amlodipine, 41.0 ng/mL (95% CI, 17.4–64.7) for hydrochlorothiazide, and 352.9 ng/mL (95% CI, 243.5–462.3) for valsartan. Substantial heterogeneity was present for all 3 pooled estimates. Moderator analyses identified dosage as a significant moderator for the pooled trough concentration of amlodipine (β1=0.9; P<0.05), mean age, and mean body weight for the mean trough concentration of hydrochlorothiazide (β1=2.2, P<0.05, respectively, β1=−4.0, P<0.05) and no significant moderators for valsartan. Plasma trough concentrations of amlodipine, hydrochlorothiazide, and valsartan, measured with liquid chromatography-tandem mass spectrometry, are highly heterogeneous over the different studies. Use of the pooled trough concentration as a cutoff in the biochemical assessment of adherence can result in inaccurate diagnosis of (non-)adherence, which may seriously harm the patient-physician relationship, and is therefore not recommended.

Population pharmacokinetics of gabapentin in patients with neuropathic pain: Lack of effect of diabetes or glycaemic control. Br J Clin Pharmacol 2020; 87:1981-1989. [PMID: 33118231 DOI: 10.1111/bcp.14594] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 09/22/2020] [Accepted: 09/23/2020] [Indexed: 12/12/2022] Open
Abstract
AIMS Gabapentin (GBP) is widely used to treat neuropathic pain, including diabetic neuropathic pain. Our objective was to evaluate the role of diabetes and glycaemic control on GBP population pharmacokinetics. METHODS A clinical trial was conducted in patients with neuropathic pain (n = 29) due to type 2 diabetes (n = 19) or lumbar/cervical disc herniation (n = 10). All participants were treated with a single oral dose GBP. Blood was sampled up to 24 hours after GBP administration. Data were analysed with a population approach using the stochastic approximation expectation maximization algorithm. Weight, body mass index, sex, biomarkers of renal function and diabetes, and genotypes for the main genetic polymorphisms of SLC22A2 (rs316019) and SLC22A4 (rs1050152), the genes encoding the transporters for organic cations OCT2 and OCTN1, were tested as potential covariates. RESULTS GBP drug disposition was described by a 1-compartment model with lag-time, first-order absorption and linear elimination. The total clearance was dependent on estimated glomerular filtration rate. Population estimates (between-subject variability in percentage) for lag time, first-order absorption rate, apparent volume of distribution and total clearance were 0.316 h (10.6%), 1.12 h-1 (10.7%), 140 L (7.7%) and 14.7 L/h (6.97%), respectively. No significant association was observed with hyperglycaemia, glycated haemoglobin, diabetes diagnosis, age, sex, weight, body mass index, SLC22A2 or SLC22A4 genotypes. CONCLUSION This population pharmacokinetics model accurately estimated GBP concentrations in patients with neuropathic pain, using estimated glomerular filtrationrate as a covariate for total clearance. The distribution and excretion processes of GBP were not affected by hyperglycaemia or diabetes.

Clin Exp Pharmacol Physiol 2020; 47:1545-1553. [PMID: 32323339 DOI: 10.1111/1440-1681.13329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 04/01/2020] [Accepted: 04/20/2020] [Indexed: 10/24/2022]
Abstract
Hypertension and coronary events are becoming more prevalent in aging societies, and myocardial infarction usually occurs in calcium channel blocker (CCB)-treated hypertensive patients. We herein compared the effects of cilnidipine, an L/N-type CCB and amlodipine, an L-type CCB, on post-infarct left ventricular (LV) remodelling in spontaneously hypertensive rats (SHRs). Male SHRs were subjected to 30 minutes of left coronary artery occlusion followed by reperfusion (MI group). The administration of cilnidipine (10 mg/kg/d; MI + Cil group) or amlodipine (10 mg/kg/d; MI + Aml group) was initiated one week before surgery and continued for five weeks. Both CCBs decreased blood pressure. Four weeks after surgery, cilnidipine, but not amlodipine, attenuated LV dilatation, fractional shortening impairments, end-diastolic pressure elevations, and tau elongation. In the non-infarct region, myocyte hypertrophy and brain natriuretic peptide (BNP) mRNA levels were similarly attenuated by both CCBs. On the other hand, interstitial fibrosis, the mRNA expression of collagen type III and transforming growth factor (TGF) β and immunohistological TGF β protein expression in the non-infarct region were reduced more in the MI + Cil group than in the MI + Aml group. Additionally, elevated angiotensin-converting enzyme activity and interstitial noradrenaline concentrations in the non-infarct region were reduced by cilnidipine. These results suggest that cilnidipine reduced cardiac noradrenaline concentrations and inhibited the renin-angiotensin system, which attenuated post-infarct remodelling more than amlodipine in hypertensive rats.

Abstract
AIM To investigate the influence of gestational diabetes mellitus (GDM) on the kinetic disposition and transplacental and amniotic fluid distribution of metoprolol and its metabolites O-desmethylmetoproloic acid and α-hydroxymetoprolol stereoisomers in hypertensive parturients receiving a single dose of the racemic drug. METHODS The study was conducted on hypertensive parturients with well-controlled GDM (n = 11) and non-diabetic hypertensive parturients (n = 24), all receiving a single 100 mg oral dose of racemic metoprolol tartrate before delivery. Serial maternal blood samples (0-24 h) and umbilical blood and amniotic fluid samples were collected for the quantitation of metoprolol and its metabolite stereoisomers using LC-MS/MS or fluorescence detection. RESULTS The kinetic disposition of metoprolol and its metabolites was stereoselective in the diabetic and control groups. Well-controlled GDM prolonged tmax for both enantiomers of metoprolol (1.5 vs. 2.5 h R-(+)-MET; 1.5 vs. 2.75 h S-(-)-MET) and O-desmethylmetoproloic acid (2.0 vs. 3.5 h R-(+)-AOMD; 2.0 vs. 3.0 h S-(-)-OAMD), and for the four stereoisomers of α-hydroxymetoprolol (2.0 vs. 3.0 h for 1'S,2R-, 1'R,2R- and 1'R,2S-OHM; 2.0 vs. 3.5 h for 1'S,2S-OHM) and reduced the transplacental distribution of 1'S,2S-, 1'R,2R-, and 1'R,2S-OHM by approximately 20%. CONCLUSIONS The kinetic disposition of metoprolol was enantioselective, with plasma accumulation of the S-(-)-MET eutomer. Well-controlled GDM prolonged the tmax of metoprolol and O-desmethylmetoproloic acid enantiomers and the α-hydroxymetoprolol stereoisomers and reduced by about 20% the transplacental distribution of 1'S,2S-, 1'R,2R-, and 1'R,2S-OHM. Thus, well-controlled GDM did not change the activity of CYP2D6 and CYP3A involved in metoprolol metabolism.

Abstract
BACKGROUND Neonatal effects of drugs administered to mothers before delivery depend on the quantity that crosses the placental barrier, which is determined by the pharmacokinetics of the drug in the mother, fetus, and placenta. Diabetes mellitus can alter the kinetic disposition and the metabolism of drugs. This study investigated the placental transfer of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women with gestational diabetes mellitus (GDM) submitted to peridural anesthesia. PATIENTS AND METHODS A total of 10 normal pregnant women (group 1) and 6 pregnant women with GDM (group 2) were studied, all at term. The patients received 200 mg 2% lidocaine hydrochloride by the peridural locoregional route. Maternal blood samples were collected at the time of delivery and, after placental expulsion, blood samples were collected from the intervillous space, umbilical artery, and vein for determination of lidocaine and MEGX concentrations and analysis of the placental transfer of the drug. RESULTS The following respective lidocaine ratios between the maternal and the fetal compartments were obtained for groups 1 and 2: umbilical vein/maternal peripheral blood, 0.60 and 0.46; intervillous space/maternal blood, 1.01 and 0.88; umbilical artery/umbilical vein, 0.77 and 0.91; and umbilical vein/intervillous space, 0.53 and 0.51. The following MEGX ratios for groups 1 and 2 were, respectively, fetal/maternal, 0.43 and 0.97; intervillous space/maternal blood, 0.64 and 0.90; umbilical artery/umbilical vein, 1.09 and 0.99; and umbilical vein/intervillous space, 0.55 and 0.78. CONCLUSION Gestational diabetes mellitus did not affect the transplacental transfer of lidocaine but interfered with the transfer of MEGX, acting as a mechanism facilitating the transport of the metabolite.

Abstract
Abstract
Objectives
The aim of this study was to evaluate the influence of poorly controlled type 1 (T1DM) and type 2 diabetes mellitus (T2DM) on the pharmacokinetics and metabolism of tramadol enantiomers in patients with neuropathic pain.
Methods
Nondiabetic patients (control group, n = 12), patients with T1DM (n = 9) or T2DM (n = 9), all with neuropathic pain and phenotyped as cytochrome P450 2D6 extensive metabolizers, received a single oral dose of 100 mg racemic tramadol. Serial blood samples were collected over a 24-h period.
Key findings
Patients with T1DM showed reduced Cmax of both tramadol enantiomers. The plasma concentrations of the active (+)-M1 were significantly reduced in T1DM (area under the curve plasma concentration versus time (AUC∞): 313.1 ng·h/ml) when compared with nondiabetic patients (AUC∞: 1246.6 ng·h/ml). The fraction unbound of (+)-M1 was increased in patients with T1DM. Patients with T1DM and T2DM showed reduced AUC and increased fraction unbound of (−)-M1.
Conclusions
The reduced total plasma concentrations of the active (+)-M1 in patients with T1DM may not be of clinical relevance because they are counterbalanced by the increased fraction unbound.

Abstract
The objective of the present study was to assess the influence of type 1 and type 2 diabetes mellitus on the enantioselective pharmacodynamics and pharmacokinetics of fenoprofen. Patients with diabetes mellitus type 1 (n = 7) or type 2 (n = 7) and healthy volunteers (n = 13) received orally a single 600-mg dose of racemic fenoprofen. Monocompartmental analysis of (+)-(S)-fenoprofen showed a significant difference (P < .05, Kruskal-Wallis test) in area under the curve (AUC) values (153.68 vs 243.50 microg x h/mL) and oral clearance (1.95 vs 1.23 L/h) only between patients with diabetes mellitus type 2 and healthy volunteers. The inhibitory activity of cyclooxygenases was evaluated indirectly by the determination of prostaglandin E2 (COX-2) and thromboxane B2 (COX-1) using the sigmoidal inhibitory Emax model. The patients with type 2 diabetes mellitus presented lower IC50 (3.29 vs 6.0 microg/mL) and g (0.73 vs 2.01) values for COX-1 activity compared to healthy volunteers (P < .05, Kruskal-Wallis test). These results show that diabetes mellitus type 2, but not type 1, influences the pharmacokinetics and pharmacodynamics of (+)-(S)-fenoprofen.

Abstract
BACKGROUND Peridural blockade with lidocaine, bupivacaine, and fentanyl is an anesthetic procedure extensively used in obstetrics, justifying the pharmacokinetic study of these drugs during labor. OBJECTIVE To investigate the influence of the physiopathological changes of gestational diabetes mellitus (GDM) on the pharmacokinetics of lidocaine and its metabolite monoethylglycinexylidide (MEGX) in pregnant women subjected to peridural anesthesia. PATIENTS AND METHODS Ten normal pregnant women (group 1) and six pregnant women with GDM (group 2) were studied, all of them at term. The patients received 200 mg 2% lidocaine hydrochloride without a vasoconstrictor by the peridural locoregional route. Maternal blood samples were collected at predetermined times for the analysis of lidocaine and MEGX by chromatography and pharmacokinetic analysis. RESULTS The median pharmacokinetic parameters of lidocaine for groups 1 and 2 (P </= 0.05), respectively, were as follows: for Cmax 879.11 and 1,145.58 ng/ml, AUC(0-infinity) 256.01 and 455.95 mug min(-1) ml(-1), Cl/f/kg 10.61 and 5.64 ml min(-1) kg(-1), and Vd/f/kg 3.26 and 2.19 L/kg. The median pharmacokinetic parameters of MEGX for groups 1 and 2 (P </= 0.05), respectively, were as follows: for Cmax 82.71 and 141.38 ng/ml, Tmax 44.71 and 193.14 min, t(1/2)alpha 7.64 and 59.77 min, alpha 0.097 and 0.012/min, and AUC(0-infinity) 29.91 and 108.23 mug min(-1) ml(-1). CONCLUSION The present data permit us to conclude that the apparent clearance of lidocaine and MEGX was reduced in diabetic patients compared to normal women, suggesting that GDM inhibits the CYP1A2/CYP3A4 isoforms responsible for the metabolism of this drug and its metabolite.
