A randomized two-way crossover bioequivalence study in healthy adult volunteers of paediatric zidovudine/lamivudine/nevirapine fast-disintegrating fixed-dose combination tablet.

Objective: The bioequivalence study was conducted to compare the developed paediatric fixed-dose combination (FDC) zidovudine/lamivudine/nevirapine (60/30/50 mg) tablet - the test formulation - with the combined mixture of single-entity innovator products (reference product).

Methods: A single-dose open-label randomized two-way crossover study was conducted in healthy adult African volunteers after an informed consent was obtained. The 24 volunteers, divided into two groups, were administered the products after an overnight fast on two treatment days with 14 days of washout period.
