    Abstract:
    Suscard is a buccally administered formulation which provides rapid introduction of nitroglycerin directly into the systemic circulation and, by virtue of its sustained-release properties, may confer protection against anginal attacks for several hours. Its efficacy has been established in angina pectoris and more recently its usefulness has been extended to include the management of unstable angina and acute heart failure. Buccal nitroglycerin combines the possibilities of short-term treatment and more extended prophylaxis. In a multicentre double-blind study the efficacy of buccal nitroglycerin and sublingual nitroglycerin were compared in patients with proven chronic stable exercise-induced angina as regards anginal attacks and capacity for physical activity. The conclusion is that the two formulations of nitroglycerin have a comparable effect in the treatment of acute attacks of angina pectoris. Buccal nitroglycerin has many advantages when used prophylactically. This is documented by less frequent anginal attacks and a more prolonged duration of effect resulting in an increased physical activity.
