New sex lubricant
could block HIV, herpes

Australian researchers have engineered a sex lubricant that could block HIV and herpes, reports The [Sydney] Daily Telegraph's Web site.

The microbicide gel, called Viva Gel, was tested on lab animals. Recent trials have shown the gel to be 85% to 100% effective, according to the article.

Viva Gel's central ingredient is the molecule dendrimer, which can bind itself to the AIDS virus as well as the virus responsible for genital herpes, preventing their ability to infect healthy cells.

The first trials of humans are under way. Initial reports call the lubricant "safe and well-tolerated" in healthy men. The lubricant is also being tested as a contraceptive for women. (The Advocate)
