Abstract Objective The objectives of this study were to investigate the antifungal susceptibility and genetic diversity Candida albicans isolated from HIV + patients with oropharyngeal candidiasis. A total 50 C. isolates cultured on Sabouraud glucose agar containing chloramophenicol. against fluconazole, clotrimazole, nystatin, amphotericin B, ketoconazole flucytosine was assessed using disc di...

The effects of the cytochrome P450 inhibitors clotrimazole, ketoconazole, and 1-aminobenzotriazole (1-ABT) on native delayed rectifier (K(DR)) and cloned Kv1.5 (RPV Kv1.5) K+ channels of rabbit portal vein (RPV) myocytes were determined using whole-cell and single channel patch-clamp analysis. Clotrimazole reduced K(DR) and RPV Kv1.5 whole-cell current with respective Kd values of 1.15 +/- 0.39...

Ketoconazole is a potent CYP3A4/5 inhibitor and, until recently, recommended by the Food and Drug Administration (FDA) and the European Medicines Agency as a strong CYP3A4/5 inhibitor in clinical drug-drug interaction (DDI) studies. Ketoconazole sporadically causes liver injury or adrenal insufficiency. Because of this, the FDA and European Medicines Agency recommended suspension of ketoconazol...

Variable interindividual expression of cytochrome P450 3A presents a challenge in dosing drugs. The use of potent inhibitors of CYP3A such as ketoconazole has been explored to reduce the clearance of CYP3A substrates, thereby resulting in smaller dose requirements; however, the impact of CYP3A inhibition on interindividual variability has not been well characterized. Our objective was to examin...

A direct study evaluating whether differential drug uptake of topical 2% miconazole and 2% ketoconazole from cream formulations into human stratum corneum correlated with differential pharmacological activity against Candida albicans was investigated in healthy human subjects. A single 24-h topical dose of 2% ketoconazole cream or 2% miconazole cream was applied unoccluded, at the same dose (2....

CONTEXT Although transsphenoidal surgery remains the first-line treatment in Cushing's disease (CD), recurrence is observed in about 20% of cases. Adjunctive treatments each have specific drawbacks. Despite its inhibitory effects on steroidogenesis, the antifungal drug ketoconazole was only evaluated in series with few patients and/or short-term follow-up. OBJECTIVE Analysis of long-term horm...

      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...
