Abstract
PURPOSE OF REVIEW: To summarise the advances that have been made from 2017 in dual, triple, and quadruple low-dose combination therapy for treating high blood pressure. RECENT FINDINGS: Many people require multiple blood pressure lowering medicines to achieve target blood pressures, and initiating treatment with combination blood pressure lowering therapy is being increasingly investigated and recommended. Low-dose combinations of blood pressure lowering provide more effective blood pressure lowering, with fewer adverse events. Recent advances include listing of four dual combinations on the WHO Essential Medicines List, completion of a triple half-dose combination trial, and a pilot of quadruple quarter-dose combination, and recent cardiovascular polypill trials have included two blood pressure lowering medicines at low dose. These trials all demonstrated improvements in achieving blood pressure targets with low-dose combination therapy. Low-dose combination therapy is a promising option for initial treatment of hypertension that appears to be safe and effective. Larger trials of triple and quadruple low-dose combination therapy in multiple locations are underway and should provide stronger evidence of efficacy as well as information on the side effect profile.
