What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Bioavailability comparison using Cmax	7 days
Bioavailability comparison using AUC	7 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The incidence rates of AEs, TEAEs and Serious Adverse Events (SAEs)	Numbers and incidence rates of AEs, TEAEs and Serious Adverse Events (SAEs) will be tabulated using available version of Medical Dictionary for Regulatory Activities (MedDRA) preferred term (PT), system organ class (SOC), severity and relationship. A patient having the same AE will be counted only once in calculating frequency while patient having same AE with different start date then both will be considered for calculating frequency. If AE is with same start date but different criteria (severity, relationship to study medication and outcome), worst case/latest case (whichever applicable) will be considered. Incidence of AEs will be summarized with count (%).	7 days
