The inhibitory activity of tea against tumorigenesis has been demonstrated in many animal models and has been suggested by some epidemiological studies. Such activity has generally been attributed to tea catechins. To understand the bioavailability of tea catechins in humans, we gave 18 individuals different amounts of green tea and measured the time-dependent plasma concentrations and urinary ...

Quantitative whole-body autoradiography was used to assess the distribution and tissue penetration of isavuconazole in rats following single and repeated oral-dose administration of radiolabeled isavuconazonium sulfate, the prodrug of isavuconazole. Following a single-dose administration of radiolabeled isavuconazonium sulfate (labeled on the active moiety), radioactivity was detectable within ...

In a previous contribution to this journal (Froese et al. 2012), we refuted criticism of a simple method (Froese and Kesner-Reyes 2002) that derives information about the status of global stocks from global catch data. This method assumes that, for a given stock, the ratio of current catches to previous maximum catches (Cmax) is indicative of the likely current exploitation status of the stock....

Glimepiride/metformin(2/500mg) is an oral antihyperglycemic agent for the treatment of type 2 diabetes. A generic glimepiride/metformin(2/500mg) fixed-dose combination(FDC) tablet was developed recently. This study was designed to collect data for submission to Korean regulatory authorities to allow the marketing of the test formulation. We evaluated the comparative bioavailability and tolerabi...

The pharmacokinetic parameters of domestic and imported ranitidine hydrochloride tablets (Ranitidine, formulated and manufactured by Kharazmi Pharmaceuticals, Iran, and Zantac ? manufactured by Glaxo, UK) were measured in 14 healthy subjects following oral administration of a single 300-mg dose of each brand and compared for bioequivalence evaluation. The pharmaceutical equivalency of both fo...

OBJECTIVE To establish the bioequivalence of a 500 mg film-coated tablet of saquinavir mesylate (FCT SQV) to the 200 mg hard-capsule saquinavir mesylate (HC SQV), both boosted with ritonavir and administered under fed conditions. METHODS We carried out a multi-centre, open-label, randomized, two-sequence, four-period, two-treatment, replicated crossover study in 93 healthy men and 7 healthy w...

Hypericins, hyperforin and flavonoids are discussed as the main components contributing to the antidepressant action of St. John's wort (Hypericum perforatum). Therefore, the objective of the two open phase I clinical trials was to obtain pharmacokinetic data of these constituents from a hypericum extract containing tablet: hypericin, pseudohypericin, hyperforin, the flavonoid aglycone querceti...
