The current focus on simplifying treatment regimens for patients with human immunodeficiency virus (HIV) infection has contributed to the interest in once-daily therapy. The triphosphate of didanosine (2',3'-dideoxyinosine or DDI) has a long intracellular half-life, which supports the use of

Didanosine is a dideoxynucleoside analogue, which is phosphorylated to the active metabolite dideoxyadenosine triphosphate (ddATP) intracellularly. At therapeutic concentrations, ddATP inhibits HIV replication by inhibiting HIV reverse transcriptase. Didanosine is established as a first-line treatment for patients with HIV disease

To evaluate the pharmacokinetic interaction between tenofovir and didanosine when used in combination as a highly active antiretroviral therapy regimen. Literature retrieval was accessed through MEDLINE (1966-January 2003) using the terms tenofovir and didanosine. Abstracts from recent meetings, including the

The combination of tenofovir and didanosine results in an increase in the didanosine plasma exposure and might augment the risk for didanosine toxicity. Although pharmacokinetic studies support a didanosine dose reduction to 250 mg when used concurrently with tenofovir in
