Islatravir (EFdA, or MK-8591) is an investigational drug for the treatment of HIV infection developed by company Merck. It is classified as a nucleoside reverse transcriptase translocation inhibitor (NRTTI). 

Islatravir has activity against HIV in animal models and is being studied clinically for HIV treatment and prophylaxis. Islatravir is a nucleoside analog reverse transcriptase translocation inhibitor that, unlike other such inhibitors, inhibits HIV through multiple mechanisms, providing rapid suppression of the virus, when tested in macaques and mice.
