Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nitroglycerin is converted to nitric oxide (NO) in vascular smooth muscle, which activates guanylyl cyclase, increasing cGMP levels. This leads to dephosphorylation of myosin light chains and vasodilation, particularly in venous capacitance vessels and coronary arteries, reducing preload and afterload.
Nitroglycerin is converted to nitric oxide (NO) in vascular smooth muscle, activating guanylate cyclase and increasing cyclic guanosine monophosphate (cGMP), leading to vasodilation of peripheral arteries and veins. This reduces preload and afterload, decreasing myocardial oxygen demand.
Minitran (nitroglycerin transdermal) is applied as a transdermal patch. Initial dose: 0.2-0.4 mg/hour applied once daily. Titrate based on response and tolerance. Maximum dose: 0.8 mg/hour. The patch is worn for 12-14 hours daily with a 10-12 hour nitrate-free interval to prevent tolerance.
1-2 sprays sublingually at onset of angina; may repeat every 5 minutes up to 3 doses in 15 minutes. Prophylaxis: 1 spray 5-10 minutes before activity.

Terminal half-life is approximately 1-4 minutes for nitroglycerin; clinical effect duration is longer due to tissue distribution.
Terminal elimination half-life of nitroglycerin is 1–4 minutes; however, clinical hemodynamic effects last longer due to active metabolites and tissue distribution.
Primarily renal excretion of inactive metabolites; less than 1% excreted unchanged. Biliary/fecal elimination is minimal.
Renal excretion of inactive metabolites (nitrate ions) accounts for approximately 80% of elimination; biliary/fecal excretion is minimal (less than 5%).
