About

The purpose of this study is to study the pharmacokinetics profiles of generic lopinavir/ritonavir and Pediatric Aluvia® at reduced dose by assessing safety, tolerability and efficacy.

Full description

This is a prospective, 2 arms, randomized intensive PK study with cross over design. This design will provide us optimal information to answer our research question. First and most important, we can assess the PK when lopinavir/r is used in a dose reduced form. By randomizing the patients to either Abbott's pediatric Aluvia dose reduction or India generic LPV/r dose reduction will allow us to assess the differences in AE severity and frequency. Using the standard abbott product as a control our study will provide important information about the bioavailability of the generic product. Although it's not an original BE design we must be able to make preliminary comparisons.
