Abstract
: HIV/ AIDS is a global pandemic, one of the most challenging; with no cure for the disease, various therapies available in the form of regimens as Highly Active Anti-Retroviral Therapy (HAART) or simply Anti-Retroviral Therapy (ART) are the only way to manage the disease. The Fixed Dose Combinations (FDCs) concept has been a well-recognised improvement in pharmacotherapy for the treatment of a variety of chronic maladies like hypertension, diabetes, HIV/AIDS, and several FDC products consisting of HIV drugs are approved. These single-tablet regimens have been essential in streamlining ART, lowering pill burden and increasing adherence. Adherence to HAART is the most vital factor to ensure medication success and virologic suppression. However, adherence is faced with several barriers including adverse effects of drugs, the complexity of ART, social-cultural factors, and pill burden among others. This writing reviews the concept of adherence to ART, and its barriers while stressing pill burden as a significant one which we suggest would be solved by using Fixed Dose Combinations (FDCs).
