Washington, D.C ? A new drug to treat HIV won federal approval Friday.

The Food and Drug Administration said it approved Prezista for the treatment of the human immunodeficiency virus. The drug is the first approved HIV medication for its maker, Johnson & Johnson. It’s also the first new HIV drug approved since June 22, 2005.

The drug, also known as darunavir, is a member of the protease inhibitor class of drugs. They work by blocking protease, a protein the virus needs to make more copies of itself. Since 1995, FDA has approved 10 other protease inhibitors.

Prezista is meant for use in patients who don’t respond to treatment with other antiretroviral drugs, the FDA said.
