BACKGROUND High dose estrogens (HDEs) were frequently used as endocrine agents prior to the introduction of tamoxifen which carries fewer side effects. Due to the development of resistance to available endocrine agents in almost all women with metastatic breast cancer, interest has renewed in the use of HDEs as yet another endocrine option that may have activity. We report our experience with o...

The newer progestogens desogestrel, norgestimate, gestodene, dienogest and nomegestrol share the common property of having weak or no androgenic effects, but there is great variation between agents in their pharmacokinetic properties and hormonal activities. Both desogestrel (acting as 3-keto-desogestrel) and norgestimate (acting mainly through levonorgestrel) are prodrugs. While nomegestrol is...

The exposure of the Venice lagoon (Italy) to endocrine-disrupting compounds (EDCs) from different sources was investigated. Spatial and time distribution of EDC concentrations were determined in four sampling sessions (December 2001-May 2002) by solid phase extraction followed by high-performance liquid chromatography separation coupled with mass spectrometry detection via electrospray interfac...

The effect of semaglutide, a once-weekly human glucagon-like peptide-1 (GLP-1) analog in development for type 2 diabetes (T2D), on the bioavailability of a combined oral contraceptive was investigated. Postmenopausal women with T2D (n = 43) on diet/exercise ± metformin received ethinylestradiol (0.03 mg)/levonorgestrel (0.15 mg) once daily for 8 days before (semaglutide-free) and during (steady...

Acne vulgaris is the most common skin disease. It affects the young adult female population and generates great impact on physical and mental health. One of the treatments with good results for affected women is combined oral contraceptive pills (COCPs). The aim of this study was to determine the clinical effect of facial acne management with ethinylestradiol 20 µg/dienogest 2 mg in a cohort of...

Ethinylestradiol (EE) induces intrahepatic cholestasis in experimental animals being its derivative, ethinylestradiol 17beta-glucuronide, a presumed mediator of this effect. To test whether glucuronidation is a relevant step in the pathogenesis of cholestasis induced by EE (5 mg/kg b.wt. s.c. for 5 consecutive days), the effect of simultaneous administration of galactosamine (200 mg/kg b.wt. i....

Abstract: Aim The aim of our study was to evaluate the contamination levels selected pharmaceutically active compounds (PAC) and their potential ecological threat forested streams. Methods Samples stream water were collected in second largest city Mato Grosso do Sul State center-west Brazil. Physicochemical parameters concentrations PAC quantified samples six field campaigns. Ecological risk as...

OBJECTIVES To examine, among young women, the association of individual hormonal contraceptives, within two broad groupings, with antidepressant therapy. METHODS In a nationwide register-based study, we examined the prescription rates of antidepressant drugs in relation to individual combined hormonal and progestin-only contraceptives among Swedish women aged 16-31 years (N = 917,993). Drug d...

The present study was designed to examine the hepatoprotective effects of curcumin (CMN), resveratrol (RSV) and ursodeoxycholic acid (UDCA) against ethinylestradiol and chlorpromazine -induced intrahepatic cholestasis. Ethinylestradiol (EE) and chlorpromazine HCl (CPZ) were administered orally once daily simultaneously with the tested compounds for one week. At the end of the experimentation pe...
