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 ?max 260nm and Emtricitabine (EMT) shows ?max at 237nm and 280nm both. Tenofovir (TEF) and Emtricitabine (EMT) at their respective ?max 260 nm and 280nm shows linearity in a concentration range of 5-30 µg/mL and 5-30 µg/mL respectively. Method A employs formation and solving of simultaneous equation using 260nm and 280nm as two analytical wavelengths for both drugs using Distilled water. Method B employs measurement using 237nm (?max of EMI) and 251nm as Iso-absorptive Point.
