2. INTRODUCTION: There is great need of an antiretroviral agent with an innovative mechanism to treat patients who have infected with HIV 1 and have very little available treatment option with them. Raltegravir is new agent of a pharmaceutical class of antiretroviral drug known as integrase inhibitor. It has shown vital activity against HIV-1 and different variants of HIV-1 which has shown resistance to Result of phase antiretroviral. one studies has proven tolerated, has a limited other available It has alsothat beenraltegravir regarded is aswell class one HIV integrase inhibitors. tendancy Metabolism of raltegravir takes place with the help of glucuronidation. for drug-drug interaction, and has pharmacokinetic effect that supports twice a daily dosing irrespective of food intake. Atazanavir helps in inhibition of UAT32C, the basic pathway of clearance of raltegravir and enhance process of pharmacokinetic. Study will also focus on combination dose of raltegravir with other antiretroviral drug.

Raltegravir basically targets an HIV enzyme that integrates viral genetic material into human chromosome. Raltegravir and other integrase inhibitors are also know as strand transfer inhibitor. Raltegravir block the strand transfer step of integration and thus blocks viral replication Result of the pre-clinical study has proven that raltegravir had a guarantee to be clinically effective HIV integrase inhibitor with wide activity against circulating variants of HIV-1. Raltegravir inhibits final, integrase strand transfer reaction and hence has a novel mechanism of Biomedically raltegravir action than other drugs. has proven its efficacy; it shows less than 1000 fold selectivity for integrase with respect to human DNA polymerase. Study on mechanism of raltegravir by which it hinders HIV-1 replication has been carried out in cell culture. Early and late HIV-1 reverse transcriptase and various integrated and unintegrated forms of HIV1 DNA have been studied with the help of quantitative PCR assay. Mutation in integrase either in vitro or inpharmacokinetic vivo may result and in change in susceptibility drug. Pre-clinical toxicological studies ofofraltegravir have been carried out on rat, dog, rabbit and other species. In addition to this toxicological effect has been studied in rodents, rats and dogs.
