Abstract: Maraviroc is the first inhibitor of CCR5 co-receptors to be marketed as an antiretroviral. The pre-clinical studies and phase III trials have shown that it has a very favourable safety profile. No characteristic adverse effect of maraviroc has been identified. Unlike with aplaviroc, where its clinical development was stopped due to serious hepatoxicity, no increase in liver toxicity has been demonstrated in patients treated with maraviroc even if they are co-infected by hepatotropic virus. Nor was there any evidence of an increase in the incidence of neoplasms or serious infections in patients treated with maraviroc. In a study on naive patients, maraviroc produced nonsignificant changes in total cholesterol, LDL, HDL and triglycerides. Although CCR5 co-receptors play a role in the immune response of the body, it has not been shown whether individuals homozygote for its deletion (delta-32 mutation) have an increased risk of serious infections, with the possible exception of encephalitis due to the West Nile virus. However, long-term follow up is required on patients treated with to be able to rule out any increased susceptibility to infections or neoplasms.
