Online published on 21 July, 2018. Abstract Two simple method was developed for the simultaneous determination of tenofovir alafenamide fumarate (TAF) and emtricitabine (EMT) in combined tablets. The method involves the Simultameous equation method (Method A) and Q-Absorabnce Method (Method B). Tenofovir (TEF) has λmax 260nm and Emtricitabine (EMT) shows λmax at 237nm and 280nm both. Tenofovir and 280nm shows linearity in a concentration range of 5–30 μg/mL and employs formation and solving of simultaneous equation using wavelengths for both drugs using Distilled water. Method B employs measurement using 237nm (λmax of EMI) and 251nm as Iso-absorptive Point.
