Drug 'can greatly reduce risk of HIV infection'

Truvada, which is made by California-based Gilead Sciences, combines two antiretroviral drugs

 

A drug used to treat HIV-positive patients may offer gay and bisexual men some protection against contracting the virus, the authors of a new study say.

Trials of the combination drug Truvada among nearly 2,500 men suggested it could reduce the chances of male-to-male HIV infection by 44%.

Those using the drug regularly could further reduce the risk of infection, it was claimed.

The study is published in the New England Journal of Medicine.

Truvada is the trade name of a drug manufactured by the California-based company Gilead Sciences Inc which combines two antiretroviral drugs, used to treat Aids.

But this new study looks at whether it could be used to prevent HIV infection in the first place.
