This paper describes a sensitive spectrophotometric method developed for determination of Ketoconazole (KC) in tablets based on amplification reactions. Ketoconazole was oxidized with periodate, resulting in formation of KC2+ and iodate ions. After masking the excess periodate with molybdate, the iodate was treated with iodide to release iodine. The liberated iodine was transformed to [Formula:...

The three imidazole antimycotics clotrimazole, miconazole, and ketoconazole all inhibit the demethylation of lanosterol to ergosterol, resulting in inhibition of growth of Saccharomyces cerevisiae; this is a fungistatic action. At higher concentrations clotrimazole and miconazole are fungicidal, whereas ketoconazole is not. The fungicidal action reflects direct membrane damage by the imidazoles...

The oxidation of ketoconazole on a bare carbon paste electrode was studied voltammetrically. The results indicated that the process is irreversible and controlled by an adsorption-extraction process which allows the accumulation of the drug at the electrode surface. After the optimization of solution pH, accumulation variables and instrumental parameters, sensitive differential pulse and linear...

Background: Tinea versicolor is a superficial fungal infection caused by normal skin flora and treatable by topical and oral anti-fungal medications. Objective: To evaluate the clinical and paraclinical response and to compare possible side-effects of a single oral dose of fluconazole and ketoconazole in treatment of tinea versicolor. Patients and Methods: In this clinical trial, sixty-si...

K etoconazole, an imidazole derivative, is a broad-spectrum antifungal agent. The development of gynecomastia in some men receiving ketoconazole fostered research into the drug's inhibitory effects on the production of testosteronel 2 and, subsequently, other steroid hormones.3-5 Ketoconazole has been used in the treatment of adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (Cush...


 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 ...
