The present disclosure relates to compositions and methods for contraception that also enhance the efficacy of microbicides. Such compositions serve the dual purpose of preventing pregnancy and lessening the risk of spreading sexually transmitted diseases. More specifically, the compositions and methods relate to synergistic contraceptive microbicide and antiviral compositions comprising a combination of a contraceptive microbicide and an antiviral agent in an acidic carrier that enhances the efficacy of both the contraceptive microbicide and antiviral agent.

Provided herein are compounds and compositions useful in increasing PPARδ activity. The compounds and compositions provided herein are useful for the treatment of PPARδ related diseases (e.g., muscular diseases, vascular disease, demyelinating disease, and metabolic diseases).

The present disclosure provides compositions and methods for making and using topical compositions comprised of an isotonic, biome-friendly solution containing xylose and/or a Salvia extract. The compositions are useful for, for example, maintaining or enhancing female lower reproductive tract (LRT) homeostasis and physiological function. In particular, topical compositions of this disclosure can be formulated for use as a freshening, menopausal, fertility, and/or perineal composition.

The invention relates to the preparation of estetrol of formula (I), derivatives thereof protected at positions 3,15α,16α,17β of general formula (III), and 3-hydroxy derivatives thereof protected at positions 15α,16α,17β of general formula (IV), and to the intermediates of general formulae (III) and (IV) applied in the process. Another aspect of the invention is the use of estetrol of formula (I) obtained by the process of the invention for the preparation of a pharmaceutical composition.

Provided herein are oral drug preparations including cyproterone acetate and ethinylestradiol, dosing regimen for the drug preparations, and methods of treating diseases. The methods provided include the administration of the oral drug preparation to treat one or more symptoms of hyperandrogenic conditions or hyperandrogenic activities, to provide contraception, and to reduce a risk of vascular thromboembolism (VTE) in a subject.

The present invention relates to monolithic intravaginal rings comprising progesterone, methods of making, and uses thereof. The intravaginal rings comprise progesterone, a polysiloxane elastomer, and a pharmaceutically acceptable hydrocarbon or glycerol esters of a fatty acid.

Described herein are synthetic progestogens, such as 6β,7β:15β,16β-Dimethylene-3-oxo-17α-pregn-4-ene-21,17-carbolactone, as well as pharmaceutical compositions comprising the same. Also described are methods of use.

The present disclosure relates to compositions and methods for inhibiting inflammation and reducing the risk of spreading sexually transmitted diseases using an alginic acid-based antimicrobial compound. Such compositions provide dual protection by (1) attacking and inactivating viruses and other microbes and (2) blocking the host response that viruses trigger to invade host cells. Such compositions can also be part of an acid buffering contraceptive.

A drug delivery system is provided in the form of a controlled release, bioerodible pellet for subdermal implantation. The pellet is bioerodible, and provides for the sustained release of a pharmacologically active agent over an extended time period. As such, the drug delivery system finds significant utility in chronic drug administration. Bioerosion products are water soluble, bioresorbed, or both, obviating the need for surgical removal of the implant. Methods for manufacturing and using the drug delivery system are also provided.
