Oxyfedrine, sold under the brand names Ildamen and Myofedrin among others, is a sympathomimetic agent and coronary vasodilator which is used in the treatment of coronary heart disease, angina pectoris, and acute myocardial infarction.
[1][7] It may also act as a norepinephrine releasing agent via its major active metabolite norephedrine.
[6][7] Oxyfedrine has been marketed in Europe, Hong Kong, India, Central America, and elsewhere.
[2] It has been found to depress the tonicity of coronary vessels, improve myocardial metabolism (so that heart can sustain hypoxia better) and also exert a positive chronotropic and inotropic effects,[1] thereby not precipitating angina pectoris.
The latter property (positive chronotropic and inotropic effects) is particularly important, because other vasodilators used in angina may be counter productive causing coronary steal phenomenon.
