BACKGROUND Pityriasis versicolor (PV), also known as tinea versicolor, is caused by Malassezia species. This condition is one of the most common superficial fungal infections worldwide, particularly in tropical climates. PV is difficult to cure and the chances for relapse or recurrent infections are high due to the presence of Malassezia in the normal skin flora. This review focuses on the clin...

in this study, the pharmacokinetic parameters of two marketed tablet formulations of ketoconazole were studied, and the relative bioavailability of the test formulation was compared with a reference formulation. a single dose (12x2) double blind randomized cross-over study of a generic formulation of ketoconazole tablet (2x200 mg), and a commercial brand, nizoral tablet (2x200 mg, janssen pharm...

Eumycetoma is a chronic progressive disabling and destructive inflammatory disease which is commonly caused by the fungus Madurella mycetomatis. It is characterized by the formation of multiple discharging sinuses. It is usually treated by antifungal agents but it is assumed that the therapeutic efficiency of these agents is reduced by the co-existence of Staphylococcus aureus co-infection deve...

: For the determination of ketoconazole in bulk and pharmaceutical dosage form accordance with ICH guidelines, a new, economical, precise, sensitive, linear, accurate, quick UV-Spectrophotometric approach has been developed Methylene chloride. The UV-visible spectrum Ketoconazole was examined to determine its maximum absorption wavelength that is λ max at 255.2 nm. Linearity, accuracy, precisio...

Glucuronidation of morphine in humans is predominantly catalyzed by UDP-glucuronosyltransferase 2B7 (UGT2B7). Since our recent research suggested that cytochrome P450s (P450s) interact with UGT2B7 to affect its function [Takeda S et al. (2005) Mol Pharmacol 67:665-672], P450 inhibitors are expected to modulate UGT2B7-catalyzed activity. To address this issue, we investigated the effects of P450...

Saquinavir, a potent human immunodeficiency virus protease inhibitor, is extensively metabolized by CYP3A4. Saquinavir is coadministered with ritonavir, a strong CYP3A4 inhibitor, to boost its exposure. Ketoconazole is a potent CYP3A inhibitor. The objectives of this study were to investigate the effect of ketoconazole on the pharmacokinetics of saquinavir/ritonavir and vice versa using the app...
