Drug Delivery and Dosage Form Deployment

in the Female Reproductive Tract

Research Focus

Our research focuses on analysis of drug delivery to the lower female reproductive tract for purposes of prophylaxis against sexually transmitted diseases and/or for contraception. The primary motivation is delivery of topical microbicides to prevent infection with HIV. We study the distribution and retention ("deployment") of topical microbicidal formulations (e.g. gels or creams) over epithelial surfaces (where infection can begin). We also assess "delivery" of microbicidal molecules from those formulations to target fluids, tissues and pathogens in the vaginal environment. Fundamental studies integrate fluid and solid mechanics, rheology, surface science and mass transport processes, to understand the biophysical mechanisms of deployment and delivery. These basic studies are linked to direct measurements, using new instruments we are developing, of formulation distributions in the lower female reproductive tracts of women. We are also analyzing the adequacy of coating and drug delivery in neutralizing semen-borne HIV and inhibiting of early events of viral replication.

Our multidisciplinary research interfaces with developments, in the public and private sectors, of new molecules and products for use by women in preventing sexually transmitted diseases and/or for contraception. Support for our work has been received from the National Institutes of Health, the CONRAD program, the FDA, the American Foundation for AIDS Research, and the Institute for Reproductive Health.
