FDA approves Truvada as HIV preventive
San Francisco Chronicle

The U.S. Food and Drug Administration on Monday approved the marketing of the first drug shown to curb the transmission of the HIV virus, a development heralded by AIDS advocates and physicians as a turning point in the battle against the decades-long epidemic.

Truvada, made by Gilead Sciences in Foster City, was approved in 2004 to treat people already infected with HIV, but studies have shown the drug is also effective at reducing the risk of contracting the virus.
