Abacavir (ABC)
Abacavir (ABC) is a nucleoside analog reverse transcriptase inhibitor (NRTI) used to treat HIV and AIDS. It has been well tolerated: the main side effect is hypersensitivity, which can be severe, and in rare cases, fatal. Viral strains that are resistant to zidovudine (AZT) or lamivudine (3TC) are generally sensitive to abacavir (ABC), whereas some strains that are resistant to AZT and 3TC are not as sensitive to abacavir. Abacavir tablets and oral solution, in combination with other antiretroviral agents, are indicated for the treatment of HIV-1 infection. Abacavir should always be used in combination with other antiretroviral agents. Abacavir should not be added as a single agent when antiretroviral regimens are changed due to loss of virologic response. ABC is an analog of guanosine (a purine). Its target is the viral reverse transcriptase enzyme.
