Abstract: Disclosed are compositions for inhibiting transmission of a sexually transmitted infection that contain one or more polyanionic microbicides, such as carrageenans, including lambda carrageenan, as well as water-soluble metal salts and specified lectins. Also disclosed are methods for making and using the compositions.

Abstract: Methods for treating neurodegeneration and/or myelination in patients are disclosed comprising treating the patient with a progestin compound which exerts binding to progesterone receptors and elicits progesterone-receptor-induced biological responses without interacting with the androgen receptor and without inducing androgen or glucocorticoid biological responses at a dosage sufficient to prevent or reduce neurodegeneration. The progestin compound preferably comprises 16-methylene-17?-acetoxy-19-norpregn-4-ene-3,20-dione, and the methods include combining the progestin compound with an estrogen compound to provide both contraception and treatment for myelin repair and neurodegeneration, and include effects on stroke and TBI.

Abstract: Methods for effective remyelination in patients are disclosed comprising treating the patient with an androgen receptor ligand which exerts binding to androgen receptors and elicits androgen-receptor-induced biological responses at a dosage sufficient to induce remyelination. The androgen compound preferably comprises MENT in an androgen targeting both androgen and estrogen receptors, and the methods include combining the androgen compound with a progestin compound in order to provide both contraception in men and treatment for neurodegeneration.

Abstract: A process ethynylates 16-methylene-17-keto steroids to the corresponding 16-methylene-17?-ethynyl-17?-hydroxy steroids by treatment with silyl-protected lithium acetylides followed by further desilylation. The resulting products are useful intermediates in the preparation of several pharmaceutically active agents, such as e.g. Nestorone® or melengestrol acetate.

Abstract: Multi-layered vaginal rings 2 comprising silicone elastomers and pharmaceutically active ingredients are disclosed. The rings comprise a number of layers, at least one of which contains a pharmaceutically active ingredient, and each of which is a silicone elastomer. The multiple layers preferably are produced from these layers of different compositions, including an inner layer 4, a middle layer 5, and an outer layer 6. After extrusion and simultaneous curing, however, the ring 2 includes a contiguous body which comprises a continuous silicone body providing unimpeded diffusion of the pharmaceutically active ingredient from the inner layer (s) 4 to the outer layer (s) 6. Methods of producing these vaginal rings and of using them are also disclosed.

Abstract: Disclosed are compositions for inhibiting transmission of a sexually transmitted infection that contain one or more polyanionic microbicides, such as carrageenans, including lambda carrageenan, as well as water-soluble metal salts and specified antiretroviral agents comprising NNRTIs and NRTIs. Also disclosed are methods for making and using the compositions. Also disclosed are intravaginal rings for delivering water-soluble compounds, and preferably high molecular weight water-soluble polymers at essentially a zero order rate. The rings include an outer layer of non-water-swellable elastomer, and preferably high molecular weight water-soluble polymer and an inner layer of the water-soluble polymer, which is imbedded in the outer layer, and an aperture through the outer layer for release thereof only through that aperture.

Abstract: Methods for treating neurodegeneration and/or myelination in patients are disclosed comprising treating the patient with a progestin compound which exerts binding to progesterone receptors and elicits progesterone-receptor-induced biological responses without interacting with the androgen receptor and without inducing androgen or glucocorticoid biological responses at a dosage sufficient to prevent or reduce neurodegeneration. The progestin compound preferably comprises 16-methylene-17?-acetoxy-19-norpregn-4-ene-3,20-dione, and the methods include combining the progestin compound with an estrogen compound to provide both contraception and treatment for myelin repair and neurodegeneration, and include effects on stroke and TBI.

Abstract: The invention discloses compositions and methods for ensuring in both women of fertile age where it ensures also a contraception with additional health benefits and in postmenopausal women where it offers a hormonal therapy with additional medical benefits such as the potential for lower risk of thrombosis. The aforementioned compositions comprising NES as a potent progestational and antiovulatory agent with no androgenic nor estrogenic nor glucocorticoid effect, and combined with estradiol formulated for non-oral transdermal administration as specific daily doses.
