Sulrnazole (the former AR-L 115 BS) is a benzimidazole derivative with positive inotropic, positive chronotropic and vasodilator effects. Sulrnazole also has been shown to improve cardiac index and reduce pulmonary capillary wedge pressure without significant change in heart rate or arterial pressure. Intravenous administration caused a 217 per cent increase in cardiac output with a 25 per cent decrease in pulmonary wedge pressure. Short-term oral administration resulted in a 317 per cent increase in cardiac index and a 317 per cent increase in ejection fraction. Side effects have included visual blurring and transient colour blindness. Sulmazol has been demonstrated to improve regional wall motion in patients with ischemic heart disease and to abolish pacing-induced ischemia. Sulrnazole is an A1 adenosine receptor antagonist. It is also a phosphodiesterase inhibitor.

Route of Administration: Intravenous

In Vitro Use Guide

Under normoxic conditions, sulmazole displayed a positive inotropic action with acceleration of relaxation of isolated mammalian myocardium at small concentrations ( 6.4 umol/L). Increasing doses led to a negative inotropic effect with slackened relaxation and loss of its load sensitivity (up to 390 umol/L for sulmazole).
