ALPROSTADIL vs TRAVOPROST
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.
Travoprost is a synthetic prostaglandin F2α analog that acts as a selective FP receptor agonist. By binding to FP prostanoid receptors, it increases uveoscleral outflow of aqueous humor, reducing intraocular pressure.
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 of 0.004% ophthalmic solution in the affected eye(s) once daily in the evening.

Clinical Note
moderatePirlindole + Travoprost
"Pirlindole may increase the hypotensive activities of Travoprost."
Clinical Note
moderateTiaprofenic acid + Travoprost
"The therapeutic efficacy of Travoprost can be decreased when used in combination with Tiaprofenic acid."
Clinical Note
moderateCarprofen + Travoprost
"The therapeutic efficacy of Travoprost can be decreased when used in combination with Carprofen."
Clinical Note
moderateBosentan + Travoprost
5-10 minutes; rapidly metabolized in the lungs, clinical effect lasts longer due to continuous infusion.
Terminal elimination half-life is approximately 45 minutes (range 17–86 minutes) for travoprost free acid in plasma; clinical effect (IOP reduction) persists longer due to prolonged receptor binding.
Primarily via urine (90%) as metabolites; 10% unchanged; minimal fecal excretion.
Renal (approximately 20% as unchanged drug and free acid metabolites); biliary/fecal (about 60% as metabolites)
