Ketoprofen, a potent nonsteroidal anti-inflammatory drug, is clinically administered as a racemic mixture. One of the possible metabolism routes of ketoprofen is the inversion of the R- to S-enantiomer in the gastrointestinal tract. Ketoprofen, as a weak acid drug, might undergo recirculation through pancreatic/intestinal juices. The aim of the work was to(More)
Sixteen healthy volunteers (8 women and 8 men) participated in a 2-period, 2-treatment crossover study. A delayed-release gastroresistant formulation of ketoprofen was administered under fasting and fed conditions. Cmax , AUC, Cmax /AUC, and kel obtained after food coadministration did not differ from those calculated under fasting administration.(More)
Although sex-related differences in gastrointestinal physiology have been vastly reported, its impact on drug oral bioavailability and bioequivalence (product discrimination) is often ignored. On this work results from an average bioequivalence study between tablets containing 600mg of the antiretroviral efavirenz (EFV), carried out with 14 healthy subjects(More)
Valproic acid, a branched short-chain fatty acid, has numerous action mechanisms which turn it into a broad spectrum anticonvulsant drug and make its use possible in some other pathologies such as bipolar disorder. It is extensively metabolized in liver, representing β -oxidation in the mitochondria one of its main metabolic route (40%). Carnitine is(More)
The objective of the current study was to examine safety and pharmacokinetic data obtained from a bioequivalence study of two brands of efavirenz carried out in healthy volunteers in order to assess the relationship between concentrations and appearance of adverse events. Drowsiness was reported in almost all the subjects 1 or 2 hours post dosing and(More)
The aim of this work was to study the effect of the sex and the smoking status on the pharmacokinetics and the bioequivalence assessment of a branded and a generic cyclosporine A microemulsion formulation in soft-gelatin capsule. Sixteen healthy volunteers (eight women and eight men) participated in a CyA bioequivalence study, with nine of the volunteers(More)
The efavirenz pharmacokinetic raw data presented in this article was obtained in an average bioequivalence study between a local brand and Stocrin (Merck Sharp & Dohme, purchased from Australia, batch H009175, expiration date November 2013). Dose was administered at night (9:00 p.m.) two hours after food intake. Fourteen healthy subjects, 8 women and 6 men,(More)
