In this text we evaluated the in vitro antifungal activities of terbinafine combined with caspofungin, miconazole, ketoconazole, and fluconazole against 17 Pythium insidiosum strains by using the microdilution checkerboard method. Synergistic interactions were observed with terbinafine combined with caspofungin (41.2% of the strains), fluconazole (41.2%), ketoconazole (29.4%), and miconazole (1...

Dihydrotestosterone (DHT) binding to androgen receptors (AR) in hair follicles is commonly accepted as the first step leading to the miniaturizing of follicles associated with androgenetic alopecia (AGA). Testosterone is converted to DHT by the enzyme 5alpha-reductase. Finasateride a 5alpha-reducase inhibitor blocks the production of DHT and is currently used to treat AGA. The inhibition is not...

Ketoconazole topical is an antifungal medication. Ketoconazole topical prevents fungus from growing on your skin. The aim of the present investigation was to design and formulate an appropriate microspheres loaded gel (MLG), and explore the parameters affecting the morphology and other characteristics of the resultant products employing scanning electron microscopy (SEM). Microspheres loaded to...

Antifungal azoles inhibit ergosterol biosynthesis by interfering with lanosterol 14α-demethylase. In this study, seven upregulated and four downregulated ergosterol biosynthesis genes in response to ketoconazole treatment were identified in Neurospora crassa. Azole sensitivity test of knockout mutants for six ketoconazole-upregulated genes in ergosterol biosynthesis revealed that deletion of on...

Without treatment, Cushing's disease has significant morbidity and mortality. Where a surgical approach may not be feasible, or is refused by the patient, medical therapy becomes the only option. In this case report, we discuss the effects of two years of ketoconazole treatment on diabetes regulation and insulin resistance in a patient reluctant to agree to surgery. A 62 year-old female patient...

In vitro screening for drug-drug interactions is an integral component of drug development, with larger emphasis now placed on the use of in vitro parameters to predict clinical inhibition. However, large variability exists in Ki reported for ketoconazole with midazolam, a model inhibitor-substrate pair for CYP3A. We reviewed the literature and extracted Ki for ketoconazole as measured by the i...

UNLABELLED Medical therapy for Cushing's syndrome due to bilateral macronodular adrenal hyperplasia (BMAH) is generally administered for a limited time before surgery. Aberrant receptors antagonists show inconsistent efficacy in the long run to prevent adrenalectomy. We present a patient with BMAH, treated for 10 years with low doses of ketoconazole to control cortisol secretion. A 48-year-old ...

A new triazole, Bay R 3783, was compared with ketoconazole, itraconazole, and fluconazole, which were given via the alimentary tract at three dosages, and amphotericin B, which was given at 1 mg/kg intraperitoneally, in murine models of the systemic mycoses coccidioidomycosis, histoplasmosis, and blastomycosis. In a pulmonary coccidioidomycosis model, Bay R 3783, fluconazole, and itraconazole w...
