Nitroglycerin dosing consisted of 2,000 mcg every 3 minutes, to a maximum of 20,000 mcg. Differences between nitrates: role of isosorbide 2-mononitrate These data suggest that 2MN is able to induce a lower cGMP increase and less tolerance induction; since these observations seem to be correlated, the vasodilator effect of 2MN probably also involves mechanisms other than stimulation of guanylate cyclase.
