There is scarce information about the effects of danazol and its derivatives at cardiovascular level. In addition, to date the cellular site and mechanism of action of danazol at the cardiovascular level is very confusing. In order to clarify those phenomena in this study, a danazol derivative was synthesized with the objective of evaluating its activity on perfusion pressure and coronary resis...

OBJECTIVE The responses of 32 patients with paroxysmal nocturnal hemoglobinuria (PNH) were assessed after the patients were put on various combinations of danazol, prednisolone, and cyclosporine. MATERIALS AND METHODS Nineteen males and 13 females aged between 14 and 60 years with confirmed diagnosis of PNH were treated with danazol (4), danazol + cyclosporine (7), cyclosporine (1), and predn...

Investigating the interference of danazol in testosterone radioimmunoassays, we measured serum testosterone concentrations in the serum of women receiving danazol, with three testosterone radioimmunoassay kits. All of these showed positive interference by danazol or its metabolites (or both). Values for testosterone obtained with two of the methods (Diagnostic Products Corp. and Farmos Diagnost...

Hereditary angio-oedema is characterised by recurrent episodes of laryngeal, intra-abdominal, facial or peripheral oedema. Danazol can be used as prophylaxis for recurrent attacks. Hepatotoxicity is a recognised adverse effect of danazol. We report an exceptional case of a danazol-induced hepatocellular carcinoma in a 75-year-old patient with hereditary angio-oedema.

Pseudotumor cerebri (PTC) is a seldom seen entity characterized by signs and symptoms associated with the intracranial hypertension (IH) without obvious causes. Some medical disorders and exogenous agents have been implicated in the development of PTC. Danazol is a popular gonadotropin inhibitor used for the treatment of endometriosis, breast disease and hereditary angioedema. While PTC has bee...

This double-blind, randomized, crossover study compared the efficacy and safety of danazol (100 mg twice daily) with matching placebo in the treatment of severe premenstrual syndrome. Nineteen patients were randomly allocated to receive danazol for 3 months followed by placebo, and 18 to receive treatment in the reverse order. Assessments of overall condition showed improvement to be statistica...

BACKGROUND The purpose of this study was to evaluate the efficacy and safety of nafarelin, a gonadotropin-releasing hormone (GnRH) analogue, versus danazol in the treatment of women with endometriosis in Taiwan. METHODS Fifty-nine women with laparoscopically and pathologically confirmed endometriosis were randomized to receive nafarelin or danazol for 180 days. Efficacy was assessed from mean...

1. Danazol elevates plasma insulin, plasma glucagon and serum low-density lipoprotein concentrations and reduces the serum high-density lipoprotein concentration. 2. Associations between these disturbances were studied in 17 women receiving danazol therapy for endometriosis. Eleven women underwent intravenous glucose tolerance tests with measurement of plasma glucose, insulin, C-peptide and glu...

BACKGROUND The 17-alpha-alkylated derivatives of testosterone are often used for the prevention of oedematous episodes in hereditary angioedema with C1-inhibitor deficiency (C1-INH-HAE). However, these agents can have many adverse effects, including erythrocytosis and polyglobulia. Our aim was to investigate occurrence of erythrocytosis and polyglobulia after long-term danazol prophylaxis in C1...

Eleven simulated intestinal fluids (SIF) were designed using a Design of Experiment (DoE) approach. The DoE SIF covered range compositions fasted state human fluid (FaHIF) with regard to pH, bile salt (BS), and phospholipid (PL). Using the model compound danazol, apparent crystalline solubility (aCS) amorphous (aAS), as well supersaturation propensity was determined in media. aCS danazol depend...
