What is abacavir, lamivudine, zidovudine, and how does it work (mechanism of action)?
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 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.

What are the side effects of abacavir, lamivudine, zidovudine?
Trizivir causes the same side effect as its component drugs, abacavir, lamivudine and zidovudine. The most common side effects are:
Serious and sometimes fatal hypersensitivity reactions involving several organs have been associated with abacavir, a component of Trizivir. Symptoms include fever, rash, nausea, vomiting, diarrhea, abdominal pain, fatigue, aches, shortness of breath, cough, and sore throat. Patients should discontinue Trizivir if a hypersensitivity reaction is suspected. Patients who carry a certain genetic marker called HLA-B 5701 are at high risk for experiencing a hypersensitivity reaction to abacavir. Screening for the HLA-B 5701 allele is recommended prior to initiating therapy with abacavir.
Other important side effects of the abacavir component include:
- liver failure
- metabolic disturbance (lactic acidosis)
- decrease in blood cells,
- muscle pain
- weakness and nerve damage in the extremities (peripheral neuropathy).
