Amyl Nitrite Inhalant USP is an organic nitrite used for the relief and prophylactic management of angina pectoris. The drug is delivered via inhalation.


The principal pharmacological action of Amyl Nitrite is relaxation of vascular smooth muscle, resulting in generalized vasodilation. Although Amyl Nitrite reflexly increases heart rate and myocardial contractility which increases myocardial oxygen consumption, the reduction in ventricular wall tension results in a net decrease in myocardial oxygen consumption. By decreasing myocardial oxygen consumption, Amyl Nitrite alters the imbalance of myocardial oxygen supply which causes angina pectoris.

James Alexander’s Amyl Nitrite Inhalant USP carries an expiration date of four years.
