BACKGROUND AND OBJECTIVE Nefazodone inhibits CYP3A; therefore coadministration with CYP3A substrates such as terfenadine or loratadine may result in increased exposure to these drugs. A potential pharmacodynamic consequence is electrocardiographic QTc prolongation, which has been associated with torsade de pointes cardiac arrhythmia. Therefore a clinical(More)
OBJECTIVE To evaluate the accumulated information from genetic association studies investigating the impact of variants of the cytochrome P450 (CYP) 2C19 genotype on the clinical efficacy of clopidogrel. DESIGN Systematic review and meta-analysis with a structured search algorithm and prespecified eligibility criteria for retrieval of relevant studies;(More)
An open-label study was conducted to characterize the pharmacokinetics and antihypertensive response to irbesartan in children (1-12 years) and adolescents (13-16 years) with hypertension. Patients received single once-daily oral doses of irbesartan 2 mg/kg (maximum of 150 mg once daily) for 2 to 4 weeks (+/- nifedipine or hydrochlorothiazide). Plasma(More)
The safety, pharmacokinetics, and pharmacodynamics of single and multiple doses of the angiotensin II (AII) AT1 blocker irbesartan were assessed in healthy subjects. In this single-center, placebo-controlled, double-blind within dose group, sequential, dose-ascending study, 48 men were randomized to receive irbesartan at doses of 150 mg, 300 mg, 600 mg, or(More)
The effect of hepatic impairment on the clinical pharmacology of the angiotensin II (AII) receptor antagonist irbesartan was assessed by comparing pharmacokinetic and pharmacodynamic parameters in 10 patients with hepatic cirrhosis with a matched group of 10 healthy volunteers. The pharmacokinetics and pharmacodynamics of irbesartan, 300 mg taken orally(More)
The phosphinyl ester prodrug fosinopril, a new angiotensin converting enzyme (ACE) inhibitor, is fully hydrolysed after oral administration to the pharmacologically active diacid, fosinoprilat. This metabolite is cleared by both hepatic and renal routes, while most other ACE inhibitors are cleared exclusively by the kidney. In the present study, after(More)
The objective of this matched case-control study was to determine whether women with Même or Replicon polyurethane-covered silicone breast implants are exposed to clinically significant levels of free 2,4-TDA from biodegradation of the polyurethane foam. Urine and serum samples were obtained from 61 patients with Même or Replicon breast implants and 61(More)
Objective: The single-dose and steady-state pharmacokinetics of the HMG CoA reductase inhibitor pravastatin and its two metabolites, SQ 31 906 and SQ 31 945, were evaluated in 12 hemodialysis patients. A single 20-mg i.v. dose was employed, followed by daily oral dosing of 20 mg over four hemodialysis intervals. Results: No statistical differences in the(More)
