Telmisartan 80 mg/hydrochlorothiazide 25 mg single-pill combination in the treatment of hypertension

Introduction: International guidelines emphasize the importance of blood pressure (BP) control to reduce cardiovascular risk. Telmisartan, an angiotensin II receptor blocker, provides large BP reductions and also prevents cardiovascular events in patients at high risk. The thiazide diuretic, hydrochlorothiazide (HCTZ), has a complementary mode of action, and combination with telmisartan is an established and rational treatment option for patients uncontrolled on monotherapy. A single-pill combination (SPC) of telmisartan 80 mg with high-strength HCTZ 25 mg (T80/H25) is widely available. Area covered: Clinical data on T80/H25 SPC for the management of hypertension was identified via MEDLINE searches. T80/H25 SPC provides greater BP reductions and higher goal achievement rates in patients who cannot achieve BP goal with T80/HCTZ 12.5 mg SPC, and also as initial therapy compared with T80 monotherapy. T80/H25 also reduced BP significantly more than valsartan 160 mg/H25 combination, and demonstrated favorable tolerability in clinical trials. Expert opinion: Patients with hypertension often do not achieve BP goal, even when treated, leaving them at increased cardiovascular risk. In part this is due to poor adherence, which can be exacerbated by treatment side effects. High BP goal achievement with SPC T80/H25, with maintained tolerability, provides a treatment option for increasing BP control.
