Optical Activity UNSPECIFIED

Abacavir is a nucleoside reverse transcriptase inhibitor used for treatment of HIV infection (either alone or in combination with other antiviral drugs). It was shown that abacavir exerts its antiviral activity through its active metabolite, carbovir triphosphate. Carbovir triphosphate is a guanine analogue and a potent and selective inhibitor of viral reverse transcriptases. Upon administration, abacavir is first converted to abacavir monophosphate by ADK, then the monophosphate is deaminated to carbovir monophosphate, which is then anabolized by cellular kinases to carbovir diphosphate and then finally to carbovir triphosphate. Abacavir causes hypersensitivity reaction in patients with HLA-B*57:01 allele.

Sample Use Guides

Adults: 600 mg daily, administered as either 300 mg twice daily or 600 mg once daily. Pediatric Patients Aged 3 Months and Older: Administered either once or twice daily. Dose should be calculated on body weight (kg) and should not exceed 600 mg daily.
Route of Administration: Oral
In order to study the inhibitory effect of abacavir on HIV strains, MT-2 cell line was infected with HIV-1 strain IIIB and was treated with increasing concentrations of the drug (up to 100 uM).
