What do you Understand by Myocardial Oxygen Requirement

pharmacy

All these drug groups useful in angina both decrease myocardial oxygen requirement (by decreasing the determinations of oxygen demand) and increase myocardial oxygen delivery (by reversing coronary arterial spasm), EXCEPT:

a) Nitrates and nitrite drugs (Nitroglycerin, Isosorbide dinitrate)

b) Calcium channel blockers (Nifedipine, Nimodipine)

c) Beta-adrenoceptor-blocking drugs (Atenolol, Metoprolol)

d) Potassium channel openers (Minoxidil)
