nootnootpenguinnJust to add to this- one of the side effect of NG when given to patients with MI is "massive headache"! That's how I the question right!+2020-05-04T05:09:32Z

thatyummysliceNitrates i believe! NO --> increased cGMP in vessel smooth muscle --> myosin light chain dephosphorylate --> vascular smooth muscle RELAX --> Dilate (primarily in venous) AKA more venous capacitance --> LOWER preload and workload for heart.+272019-06-02T03:13:20Z
marbledocThanks! Thought it was nitrates too from the Q stem. But had no clue it was notorious for headaches (only thought of hypotension, dizziness, etc) so doubted it all together. But you’re absolutely right apparently it’s the most common side effect!+2019-06-02T03:14:20Z
dr.xxPreviously, Ferid Murad et al. described that organic nitrates, such as nitroglycerine, induce vasodilation by release of nitric oxide, activating soluble guanylyl cyclase and subsequent cyclic guanosine monophosphate formation.7 These discoveries rendered Robert Furchgott, Louis Ignarro, and Ferid Murad the Nobel Prize in Physiology or Medicine in 1998.
