IV PERSANTINE vs TRANSDERM-NITRO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits adenosine deaminase and phosphodiesterase, increasing intracellular cAMP and adenosine; causes coronary vasodilation and inhibits platelet aggregation.
Nitroglycerin is converted to nitric oxide (NO), which activates guanylate cyclase, increasing cGMP in vascular smooth muscle, leading to vasodilation.
0.14 mg/kg/min intravenous infusion over 4 minutes for myocardial perfusion imaging.
Initial dose 0.2-0.4 mg/hour transdermally once daily. Titrate to 0.4-0.8 mg/hour. Maximum 0.8 mg/hour.

Terminal elimination half-life is approximately 10-12 hours in adults; may be prolonged in patients with hepatic impairment.
Terminal elimination half-life is approximately 1-4 minutes after IV administration due to rapid metabolism. After transdermal application, the apparent half-life is 3-4 hours due to continued absorption from the skin depot, resulting in a prolonged clinical effect.
Primarily hepatic metabolism (glucuronidation) with enterohepatic recirculation; renal excretion of unchanged drug is minimal (<1%); biliary/fecal elimination accounts for approximately 90% of the dose.
Renal (primarily) and biliary; ~60-80% of the dose is excreted renally as metabolites, with <1% unchanged. Fecal excretion accounts for ~10-20%.
