In the present investigation, antimicrobial activity of Catharanthus roseus (leaves and stem) was evaluated. The plant material extracted through maceration method results were recorded against different bacterial (Bacillus subtilis Pseudomonas flourescence) fungal (Aspergillus flavus Fusarium culmorum) strains. zones inhibition measured these strains compared with commercially available...

Ketoconazole, a potent antifungal agent, inhibits adrenal steroidogenesis in normal subjects during short term treatment. Since this drug is used in the long term prophylaxis of fungal infections in patients with haematological malignancies, we have investigated whether such patients have evidence of adrenocortical suppression. Six patients on long term prophylaxis with ketoconazole were given ...

This double-blinded noninferiority clinical trial evaluated the use of oral fluconazole for the treatment of Malassezia dermatitis in dogs by comparing it with use of an accepted therapeutic agent, ketoconazole. Dogs presenting with Malassezia dermatitis were treated with either fluconazole or ketoconazole in addition to cephalexin for concurrent bacterial dermatitis. Statistically significant ...

The antifoaming agent simethicone (Lefax), the protease inhibitor gabexate mesilate (FOY), the antimycotic ketoconazole, and the hydroxyl scavangers dimethylsulphoxide (DMSO) and allopurinol were investigated for growth inhibition of Helicobacter pylori and representative strains of other bacterial species. H. pylori were selectively inhibited by 64-128 mg/L of simethicone, 64-128 mg/L gabexate...

Two multicenter, single-arm, single-infusion, open-label studies were conducted to evaluate the effect of ketoconazole (a strong CYP3A inhibitor) or rifampin (a strong CYP3A inducer) daily for 5 days on the pharmacokinetics (PK) and safety of romidepsin (8 mg/m(2) intravenous 4-hour infusion for the ketoconazole study or a 14 mg/m(2) intravenous 4-hour infusion for the rifampin study) in patien...

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 susceptibili...

We investigated the effects of ketoconazole on the oral bioavailability of morpholine-urea-phenylalanine-homophenylalanine-vinylsulfone-phenyl (K02), a vinylsulfone peptidomimetic cysteine protease inhibitor, and a P450 3A (CYP3A) and P-glycoprotein dual substrate, in male Sprague-Dawley rats, so as to evaluate the roles of CYP3A and P-gp in K02 disposition. Male Sprague-Dawley rats (8-10 wk ol...

We investigated the efficacy of ketoconazole, an inhibitor of testicular and adrenal biosynthesis, for treating patients with progression of hormone-refractory prostate cancer. The study comprised 35 patients with progressive disease despite salvage treatment with estramustine with or without vinblastine. Treatment consisted high-doses ketoconazole (400 mg three times daily) and hydrocortisone ...

The in vitro activity of a new triazole R126638 against Malassezia yeasts was compared with that of ketoconazole. With the agar dilution technique, minimal inhibitory concentrations were lower for R126638 compared with ketoconazole against Malassezia globosa, M. obtusa, M. slooffiae, M. restricta and two strains of M. sympodialis. On human stratum corneum in vitro, both R126638 and ketoconazole...
