ACTIONS AND CLINICAL PHARMACOLOGY
Didanosine is a synthetic, purine nucleoside analogue of
deoxyadenosine, active against the
Human Immunodeficiency Virus (HIV).
Didanosine inhibits the _in vitro_ replication of HIV in human primary
cells cultures and in
established cell lines. The active antiviral metabolite,
dideoxyadenosine-triphosphate (ddATP),
is formed in several steps by phosphorylation of didanosine by
cellular enzymes. Inhibition of
HIV reverse transcriptase by ddATP is through competition with
endogenous deoxyadenosine
triphosphate (dATP) for binding to the active site of the enzyme. In
addition, ddATP is a
substrate for reverse transcriptase and is incorporated into the
growing DNA chain. The
resulting nucleoside, dideoxyadenosine (ddA) lacks a 3'-hydroxyl
group, which normally is the
acceptor for covalent attachment of subsequent nucleoside
5'-monophosphates in DNA chain
extension. Thus, ddA incorporated in the DNA prevents further chain
extension and aborts
proviral DNA synthesis. (See CLINICAL PHARMACOLOGY).
INDICATIONS AND CLINICAL USE
VIDEX (didanosine) is indicated for the treatment of HIV-infected
patients in appropriate
antiretroviral regimens.
Clinical benefit of VIDEX was demonstrated in several important
clinical trials (see Clinical Use
subsection of CLINICAL PHARMACOLOGY).
The duration of clinical benefit from antiretroviral therapy may be
limited. Alteration in
