Abstract
The present invention provides a composition and use of a composition comprising a bioadhesive cross-linked polycarboxylic acid polymer formulation that enables the use of relatively low mounts of anti-STD infectants, such as N-9, to be used to prevent infection by STDs without causing the irritation to genital tissue that often accompanies higher doses of anti-STDs. The bioadhesive polymer maintains greater contact between the anti-STD agent and the infectant for a much greater period of time, enabling a lower concentration to act longer on the infectant, when compared to currently-available commercial applications containing N-9. Such delivery will enable a safe and non-irritating decrease in the risk of infection with STDs, including HIV.
