Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is deigned to determine if refractory hypertension is attributable to heightened sympathetic tone by quantifying the antihypertensive benefit of reserpine, a sympatholytic agent, in patients failing other classes of antihypertensive agents.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with refractory hypertension, defined as uncontrolled office blood pressure despite use of 5 or more antihypertensive agents, including a thiazide diuretic and spironolactone. After withdrawal from other centrally-acting agents if needed, enrolled patients will be randomized to open-label reserpine 0.1 mg daily for 4 weeks. Twenty-four hour ambulatory blood pressure monitoring will be done at baseline, after the initial 4-week treatment period. All other antihypertensive medications will remain unchanged during the 4-week treatment period. The primary endpoint will be change in 24-hr ambulatory systolic blood pressure.
