Brief Summary  
A randomised, open label, two-treatment, two-period, cross-over, single dose oral bioequivalence study between test product, Nirmatrelvir 300mg (2 x 150 mg) tablets and Ritonavir 100 mg tablet (Cipla Ltd., India) and the reference product,
PAXLOVID (Nirmatrelvir 300mg [2 x 150 mg] tablets and Ritonavir 100 mg tablet) (Distributed By: Pfiznr labs, Division of Pfizer Inc. New York, NYl0017) in healthy adult human subjects under fasting conditions.

To compare the rate and extent of absorption of the test product and reference product. Secondary objective is to assess the safety and tolerability of single dose of Nirmatrelvir and Ritonavir 300/100 mg Tablet in healthy adult human subjects.
Bioequivalence will be concluded if the confidence interval so constructed fall within the range of 80–125% for (ln-transformed) Cmax and AUC0-t for nirmatrelvir.
