GENERIC NAME: abacavir, lamivudine, zidovudine

BRAND NAME: Trizivir

DRUG CLASS AND MECHANISM: Trizivir is a combination oral medication that is used for treating infections with the human immunodeficiency virus (HIV). Trizivir contains abacavir (Ziagen), lamivudine (Epivir) and zidovudine (Retrovir), which are three different anti-HIV drugs with different mechanisms of action. Anti-HIV drugs are often used in combination to increase HIV suppression and to reduce the chance of the HIV virus developing resistance to any single drug. Combining these three drugs into one pill reduces the number of individual medications that a patient has to take, which makes it easier for patients to comply with therapy. Administration of one tablet of Trizivir is equal to giving 300 mg of abacavir, 150 mg of lamivudine and 300 mg of zidovudine together. Trizivir does not reduce the transmission of HIV among individuals, and it does not cure HIV or AIDS. Trizivir was approved by the FDA in November, 2000.
