BACKGROUND: Xenoestrogens and antifungal azoles probably share a common route of metabolism, through hepatic cytochrome P450 (CYP) enzymes. Chemical interactions with metabolic pathways may affect clearance of both xenobiotics and endobiotics. This study was carried out to identify possible chemical interactions by those substances on CYP1A and CYP3A, in Atlantic cod liver. We investigated effe...

Prostate cancer is the most common nonskin cancer in American men, and androgen-deprivation therapy is the cornerstone of treatment for advanced prostate cancer. Unfortunately, the median duration of response to initial androgen deprivation is limited to 18–24 months. After failing primary therapy, many individuals respond to multiple secondary hormonal interventions, such as ketoconazole. A po...

Twelve Spanish laboratories collected 325 yeast clinical isolates during a 30 day's period, among them 224 Candida albicans, 30 Candida glabrata, and 27 Candida parapsilosis. In vitro antifungal susceptibility to amphotericin B, ketoconazole, fluconazole and itraconazole was determined by an agar diffusion test (Neo-Sensitabs, Rosco, Denmark). All the isolates tested were susceptible in vitroto...

Objective: The present research was aimed to develop ketoconazole (KT) loaded microemulsion-based gel formulation for effective topical delivery through enhanced drug solubility, improved skin permeation and reduced side effects overcoming drawbacks of conventional dosage forms. Methods: For the selection oil, surfactant co-surfactant mixture (Smix) ratio, phase titration method used pseudo-ter...

ABT-384 [1-piperazineacetamide, N-[5-(aminocarbonyl) tricyclo[3.3. 1.13,7]dec-2-yl]-a,a-dimethyl-4-[5-(trifluoromethyl)-2-pyridinyl]-, stereoisomer] is a potent and selective inhibitor of 11b-hydroxysteroid dehydrogenase type 1 (HSD-1). ABT-384 has been shown to be safe and well tolerated in humans at doses up to 100 mg daily, and to fully inhibit both peripheral and brain HSD-1 at a dose of 2 ...

resistance to drug such as metronidazole is one the commonest causes of treatment failure while eradicating helicobacter pylori . considering the safety of ketoconazole and fluconazole and their inhibitory activity on biosynthesis of fatty acids from cholesterol in cell membrane of h.pylori , the idea of their efficacy against h.pylori is raising . the aim of this study is to evaluate susceptib...

abstract background: in order to evaluate the role ofketoconazole in the prevention of ovarian hyperstimulation syndrome (ohss) in women with polycystic ovary syndrome (pcos) undergoing ovarian stimulation with gonadotropins, a prospective, randomized, double-blind, placebo controlled study was done on one-hundred and nine pcos women that had been refeited to be treated by gonadotropins. method...

This study investigated the relationship among estrogen, placental blood flow and placental weight gain in rats treated with ketoconazole. Oral administration of ketoconazole (25mg/kg/day) on Days 12-14 of pregnancy induced reduction of plasma estradiol-17β (E2) concentration, transient decrease in placental blood flow and increased intensity of a hypoxia-related marker in the placenta on Day 1...

Ketoconazole, a widely used fungicide in patients, has been associated with Q-T prolongation and torsade de pointes when co-administered with terfenadine (Seldane). Both compounds use the same cytochrome-P450 metabolic pathway, resulting in an increase in plasma concentration of terfenadine. We previously showed that terfenadine blocked HERG (Human Ether-a-Gogo Related Gene), an important compo...

AIMS Two clinical studies were conducted to determine possible drug-drug interactions between apremilast and a strong CYP3A4 inhibitor, ketoconazole, or a potent CYP3A4 inducer, rifampicin. The main objectives of these two studies were to evaluate the impact of multiple doses of ketoconazole on the pharmacokinetics of apremilast and its metabolites, and the effect of multiple oral doses of rifa...
