Didanosine

Overview

A dideoxynucleoside compound in which the 3'-hydroxy group on the sugar moiety has been replaced by a hydrogen. This modification prevents the formation of phosphodiester linkages which are needed for the completion of nucleic acid chains. Didanosine is a potent inhibitor of HIV replication, acting as a chain-terminator of viral DNA by binding to reverse transcriptase; ddI is then metabolized to dideoxyadenosine triphosphate, its putative active metabolite.

Indication

For use, in combination with other antiretroviral agents, in the treatment of HIV-1 infection in adults.

Associated Conditions

Human Immunodeficiency Virus Type 1 (HIV-1) Infection
