Diltiazem In The Treatment Of Hypertension

Does A Lower Heart Rate Mean You’re Fitter? | GTN Does Science

Hypertension or high blood pressure is a chronic condition in which the blood force against the arteries walls is persistently elevated. Untreated hypertension is a major risk factor for a number of cardiovascular disorders. In this regard, calcium antagonists are a first-line treatment for hypertension . Many studies have demonstrated the effectiveness of diltiazem for the treatment of high blood pressure. Diltiazem can be used as monotherapy or in association with other antihypertensive drugs. The usual starting doses are 120240 mg/day, and it may be increased up to 540 mg/day based on individual patient needs. The dosage range studied in clinical trials was 120540 mg/day, although current clinical experience with the 540 mg dose is limited .

Thus, two independent multicenter studies assessed the safety and efficacy of various once-daily doses of diltiazem in patients with mild-to-moderate hypertension . In one study, patients were randomly treated with once-daily diltiazem or placebo for 4 weeks, and in the second study, patients were assigned to escalating dosages . The data demonstrated that once-daily doses higher than 120 mg significantly lower systolic and diastolic blood pressure compared to placebo. Additionally, adverse events were mild and with an incidence similar to placebo.
