Efavir (dideoxyinosine, ddI) is an oral nucleoside reverse transcriptase inhibitor (NRTI). It is a synthetic purine derivative and, similar to zidovudine, zalcitabine, and stavudine. Efavir was originally approved specifically for the treatment of HIV infections in patients who failed therapy with zidovudine.
