ALPROSTADIL vs TRAVATAN Z
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Alprostadil is a synthetic prostaglandin E1 (PGE1) that causes vasodilation by binding to prostanoid EP receptors, increasing intracellular cAMP, and relaxing smooth muscle. It also inhibits platelet aggregation.
Selective FP prostanoid receptor agonist; increases uveoscleral outflow of aqueous humor by binding to FP receptors in the ciliary muscle and trabecular meshwork, leading to matrix metalloproteinase activation and remodeling of extracellular matrix.
Initial: 20-40 mcg IV bolus over 1-2 seconds; then 30-70 mcg/min continuous IV infusion for erectile dysfunction via intracavernosal injection: 2.5-10 mcg; for patent ductus arteriosus: 0.05-0.1 mcg/kg/min continuous IV infusion.
One drop in the affected eye(s) once daily in the evening. Ophthalmic solution 0.004% (travoprost 0.04 mg/mL).

Clinical Note
moderateAlprostadil + Limaprost
"Alprostadil may increase the antiplatelet activities of Limaprost."
Clinical Note
moderateAlprostadil + Epoprostenol
"Alprostadil may increase the antiplatelet activities of Epoprostenol."
Clinical Note
moderateTiaprofenic acid + Alprostadil
"The therapeutic efficacy of Alprostadil can be decreased when used in combination with Tiaprofenic acid."
Clinical Note
moderateCarprofen + Alprostadil
5-10 minutes; rapidly metabolized in the lungs, clinical effect lasts longer due to continuous infusion.
Terminal elimination half-life is 45 minutes; due to rapid hydrolysis to active acid, the clinical effect duration is longer than the half-life suggests.
Primarily via urine (90%) as metabolites; 10% unchanged; minimal fecal excretion.
Primarily eliminated via hepatic metabolism; renal excretion of metabolites accounts for approximately 20% of the dose; fecal excretion is minimal.
