Drug-delivering tampons could offer women protection against HIV

Drug-delivering tampons could offer women protection against HIVResearchers at the University of Washington have developed a tampon made of rapidly dissolving fibers to deliver topical drugs that prevent women from contracting HIV. "This could offer women a potentially more effective, discreet way to protect themselves from HIV infection by inserting the drug-loaded materials into the vagina before sex," says lead author Cameron Ball, a UW doctoral student in bioengineering. Now that a recipe exists for such topical drugs that prevent HIV, called microbiocides, delivering them has been a quandary due to the quantity required, which creates a high probability of leakage. The tampons are fabricated by a process called electrospinning, which is roughly comparable on the large scale to the traditional spinning of yarn from wool.
