Tenofovir hydrate is an inhibitor of reverse transcriptase used for the treatment of the human immunodeficiency virus 1(HIV-1) and hepatitis B [1].

Tenofovir hydrate is an antiviral pro-drug and the class of nucleoside reverse transcriptase inhibitor. In addition, Tenofovir hydrate has been reported to have a dependent relation between intracellular the drug concentrations and prevent function of HIV-1infection with EC50 values of 29 fmol/106, 40 fmol/106 , 77 fmol/106 and 411 fmol/106 cells for inoculum size 1, 5, 20 and 100 respectively. And the EC90 values of tenofovir hydrate are 267 fmol/106, 348 fmol/106, 640 fmol/106 and 2866 fmol/106 cells for virus inoculums size 1, 5, 20 and 100, respectively [1].
