Mode of Action
Tenofovir disoproxil fumarate, a diester prodrug of tenofovir, is a nucleotide reverse transcriptase inhibitor. After oral absorption, tenofovir disoproxil fumarate is rapidly converted to tenofovir and then undergo subsequent phosphorylation by cellular enzymes to the active tenofovir diphosphate, which inhibits the activity of HIV-1 reverse transcriptase.
