New ways to prevent HIV explored

Tablets, insertable rings, and films might deliver drugs


 

Researchers are looking into new ways that could protect women, and maybe men, from HIV infections, including tablets, insertable rings and dissolving films. Using such an approach, called a microbicide, could help overcome some risks of drug resistance that can come with taking pills that prevent infection. A flexible ring used in the vagina can continually deliver two AIDS drugs for up to a month, researchers reported, although it hasn’t been tested in people yet. Meanwhile, a vaginal tablet worked in a similar way, using a polymer that attaches to the moist vaginal lining. In another approach, a film that’s smaller and thinner than a stick of gum is used. Microbicides using HIV drugs are expected to represent a large new market for companies that make them.
