Описание: Nitrates have been for many years the cornerstone of cardiovascular therapy for various indications. The primarily used nitrates in clinical practice are nitroglycerin and the com- plex organic nitrates, mainly isosorbide dinitrate.

Описание: Although nitroglycerin is one of the oldest drugs in cardiology the problem of tolerance is a scientific challenge of today. The proceedings of this symposium highlight the most re- cent questions related to this topic. Apparently, partial tolerance, or rather partial decrease in sensitivity, can arise during nitrate therapy. Probably this is the consequence of a partial readjustment of the vascular system. This readjustment refers particularly to the arterial system, i.e., to the hypoten- sive effect of nitrates in the standing position. A similar effect on the venous side is not present. On the other hand, the results assembled in this volume confirm the experience of many decades that long-term antianginal therapy with nitrates remains effective even when high doses are applied. Thus partial tolerance which also occurs after other vasodilators such as prazosin, does not imply tolerance against antianginal effectiveness. From the information available to- day it is reasonable to treat patients with angina pectoris acutely as well as chronically with nitrates in individually adjusted doses. Frankfurt, November 1982 M.

Описание: Pharmacological and clinical research on nitrates continues to be of growing interest in many centers. Although most investigators agree that intracellular sequestration of calcium is probably the main mechanism by which nitrates lead to the reduction of vascular smooth muscle tone, the exact site of their action still remains undefined.
