Triple Combination Therapies Based on Olmesartan: A Personalized Therapeutic Approach to Improve Blood Pressure Control.

Recent epidemiological surveys have demonstrated that effective and sustained blood pressure (BP) control is achieved in a relatively small proportion of treated hypertensive patients. Indeed, treatment of hypertension represents a key strategy for preventing coronary artery disease, stroke, congestive heart failure and cardiovascular death. Several interventions have been proposed by international guidelines for ameliorating hypertension management and control, mostly including integrated and multi-dimensional pharmacological and non-pharmacological strategies. In particular, numerous evidence demonstrated that a more extensive use of combination therapy may represent a valid therapeutic option for treating hypertensive patients at different risk profile. This strategy has been definitely strengthened by the availability of single pill fixed-dose combinations. Among potential combination therapies, those based on the association of renin-angiotensin system antagonists, thiazide diuretics and calcium channel blockers are very effective in lowering BP levels and well tolerated. We will provide here an overview of clinical evidence supporting the use of triple combination therapy, with a focus on that based on olmesartan medoxomil, a thiazide diuretic (hydrochlorothiazide) and a calcium channel blocker (amlodipine besylate), which is available in multiple dosages. Finally, in view of the recognised importance of single-pill combination therapy for treating hypertension, we will examine the potential benefits of dual (fixed) combination therapy based on olmesartan medoxomil with either thiazide diuretic hydrochlorothiazide or calcium channel blocker amlodipine in terms of efficacy, safety and tolerability profile.
