Pharmacokinetic Study of Two Generic Co-formulations of Lopinavir/Ritonavir for HIV Infected Children (SURF)

Cipla has developed two co-formulated forms of lopinavir/ritonavir for second-line antiretroviral therapy for children: Lopimune granules and Lopimune tablets. They contain 100mg lopinavir and 25mg ritonavir.

Primary objective of this study:

To determine the pharmacokinetic profile of lopinavir and ritonavir in two different co-formulations (Lopimune granules and Lopimune tablets) after single-dose in HIV-negative, healthy adult subjects, and to compare this to the branded product.

Secondary objective:

To evaluate the safety of single-dose administration of the two generic co-formulations of lopinavir/ritonavir and compare this to the branded product.
