Similarly, the influence of race on the pharmacological effects of ARVs deserves further investigation. Although, there is no reason to believe based on available evidence that racial differences exist in the pharmacological effects of ARVs, the need however exists to explore the influence of race on ARVs pharmacokinetics and treatment outcomes. This is so because data on race related differences on ARV effects is limited, and in addition, people of ethnic minority have been disproportionately under represented in clinical trials involving these drugs in spite of the fact that they bear a larger burden of the HIV epidemic.
