Information about Abacavir
Abacavir sulfate is a nucleoside analogue and reverse transcriptase inhibitor which is used in combination with other agents in the therapy of the human immunodeficiency virus (HIV) infection and the acquired immunodeficiency syndrome (AIDS). Abacavir is a rare cause of clinically apparent drug induced liver injury.
Mechanism of action of Abacavir
Abacavir (a bak' a vir) (cyclopropylaminopurinylcyclopentene: ABC) is a structural analogue of guanosine and acts by competing with naturally occurring nucleosides for incorporation into the HIV DNA strand during viral replication, causing inhibition of the viral polymerase and chain termination. Abacavir is indicated for the treatment of HIV infection in combination with other HIV medications such as lamivudine and zidovudine.
Dosage and administration for Abacavir
Abacavir is available generically and under the trade name Ziagen in a 20 mg/mL oral solution and a 300 mg oral tablet. Abacavir is also available in fixed combination with lamivudine as Epzicom and Kivexa, with zidovudine and lamivudine as Trizivir and with dolutegravir and lamivudine as Triumeq. The recommended dose of abacavir is 300 mg orally twice daily or 600 mg orally once daily in adults and 8 mg/kg orally twice daily in children larger than 15 kg, with a maximum daily dose of 300 mg.
