Binding of oral contraceptive progestogens to serum proteins and cytoplasmic receptor
1990
Abstract Some progestogens widely used in oral contraceptives are characterized at the level of high-affinity receptor binding as well as binding to sex hormone-binding globulin and corticosteroid-binding globulin. With regard to binding to sex hormone-binding globulin, gestodene, levonorgestrel, and to a lesser extent 3-ketodesogestrel (which is only formed from the prodrug desogestrel in the body), show a behavior that is manifested in the relatively high affinity to sex hormone-binding globulin, whereas desogestrel and norgestimate do not display any measurable affinity for this specific steroid-binding serum protein. Furthermore, levonorgestrel and gestodene dissociate very much more sl…
The association of serum androsterone glucuronide with inflammatory lesions in women with adult acne1
2002
Serum androsterone glucuronide (AoG) is a metabolite of circulating androgens under the influence of 5α-reductase activity and has been shown to be particularly elevated in women with acne. In this study, we wanted to evaluate changes in AoG before and after treatment with an oral contraceptive or placebo, and to assess whether changes correlated with the number and type of acne lesions. In order to accomplish these aims, we obtained sera from a completed prospective randomized trial, which was designed to assess the effectiveness of an oral contraceptive compared to placebo. Assessments were carried out in 56 women with moderate acne who were treated with Ortho Tri-Cyclen (norgestimate and…
Protrhombotic Effects of Contraceptives
2010
The use of oral contraceptives first became widespread some 40 years ago, and reports of an excess risk of cardiovascular disease among women who used these agents soon followed. Few drugs have been the object of such intensive epidemiological research, the outcome of which has provided clinicians with detailed information about risks not only of specific thrombotic diseases but also important non-contraceptive benefits from the pill. Recently, oral contraceptives have been classified by some according to "generation" (first, second, third, and most recently, fourth generation): first-generation formulations containing lynestrenol or norethindrone, second-generation formulations containing …
