Simultaneous determination of artemether and lumefantrine in fixed dose combination tablets by HPLC with UV detection

This paper describes the development and validation of a HPLC-UV method (210 nm) for the simultaneous quantitation of artemether and lumefantrine in fixed dose combination tablets. The method showed to be linear ( r 2 > 0.99), precise (R.S.D. < 2.0%), accurate (recovery of 101.07% for artemether and 101.58% for lumefantrine), specific and robust. Four batches of artemether–lumefantrine tablets were assayed by the validated method. The artemether contents in the tablets varied from 98.61% to 103.35%, while lumefantrine contents were 97.92–100.48%.
