Curator's Comment: description was created based on several sources, including https://www.ott.nih.gov/sites/default/files/documents/pdfs/VidexCS.pdf

Didanosine was developed by Bristol-Myers Squibb in collaboration with the NIH for the treatment of HIV-1 infections. Upon administration the drug is metabolized to the active metabolite which inhibits HIV-1 reverse transcriptase both by competing with deoxyadenosine 5'-triphosphate and by its incorporation into viral DNA. Didanosine was approved by FDA under the name Videx (among the other names).

Sample Use Guides

In Vivo Use Guide

In adult patients didanosine should be administered on an empty stomach at least 30 minutes before eating at the dose of 200 mg twice daily (body weight is at least 60 kg) or 125 mg twice daily (body weight is less than 60 kg). Pediatric patients (2 weeks old to 18 years old): the drug should be administered on an empty stomach at least 30 minutes before or 2 hours after eating at the dose of 100-120 mg per m2 twice daily.

The anti-HIV-1 activity of didanosine was evaluated in a variety of HIV-1 infected lymphoblastic cell lines and monocyte/macrophage cell cultures. The concentration of drug necessary to inhibit viral replication by 50% (EC50) ranged from 2.5 to 10 uM (1 uM = 0.24 ug/mL) in lymphoblastic cell lines and 0.01 to 0.1 uM in monocyte/macrophage cell cultures.
