Treatment of variant angina pectoris with perhexilene maleate

Three patients with variant angina pectoris resistant to therapy with nitrates and propranolol were treated with perhexilene maleate. Two patients had normal coronary arteries with documented coronary artery spasm, while the third patient had a fixed coronary artery obstruction. In all three patients, attacks of variant angina pectoris disappeared following institution of therapy with perhexilene maleate. When the dose of this drug was decreased to 100 mg per day or less, symptoms reappeared in all patients. Reinstitution of therapeutic doses of perhexilene maleate once again resulted in complete control of symptoms. Perhexilene maleate is therefore a useful agent for the treatment of variant angina pectoris.
