BIMATOPROST vs TRAVATAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bimatoprost is a synthetic prostamide analog that selectively mimics the effects of prostamide F2α. It binds to prostaglandin F (FP) receptors on ciliary muscle cells and trabecular meshwork cells, increasing uveoscleral outflow and possibly trabecular outflow of aqueous humor, thereby reducing intraocular pressure. It also directly stimulates the prostaglandin FP receptor, leading to increased matrix metalloproteinase activity and remodeling of the extracellular matrix in the ciliary body.
Selective FP prostanoid receptor agonist; increases uveoscleral outflow of aqueous humor by relaxing the ciliary muscle and remodeling the extracellular matrix in the ciliary body.

Clinical Note
moderateBimatoprost + Unoprostone
"Bimatoprost may increase the hypotensive activities of Unoprostone."
Clinical Note
moderateBimatoprost + Hydrochlorothiazide
"Bimatoprost may increase the hypotensive activities of Hydrochlorothiazide."
Clinical Note
moderateBimatoprost + Epoprostenol
"Bimatoprost may increase the hypotensive activities of Epoprostenol."
Clinical Note
moderateVardenafil + Bimatoprost
"Vardenafil may increase the antihypertensive activities of Bimatoprost."
Terminal half-life: ~45 minutes (intravenous); after topical ocular administration, systemic half-life is similar due to rapid systemic clearance, with clinical effect lasting 24 hours due to ocular tissue binding
Terminal elimination half-life is approximately 45 minutes for travoprost acid (active metabolite). Clinical context: due to rapid systemic clearance, ocular hypotensive effect persists for 24 hours from corneal tissue binding.
Renal: <67% (unchanged and metabolites), Biliary/fecal: ~25%
Renal (primarily as metabolites): ~70%; Fecal: ~25%; Unchanged drug in urine: <1%
