BIMATOPROST vs LUMIGAN
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.
Bimatoprost is a prostamide analog that selectively mimics the effects of prostamide F2α, activating prostaglandin F (FP) receptors. It increases aqueous humor outflow through the uveoscleral pathway and may also enhance trabecular outflow, reducing intraocular pressure.

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 78 minutes (range 54-102 minutes) in plasma after ocular administration. This short half-life reflects rapid systemic clearance, but ocular tissue levels persist longer due to local tissue binding.
Renal: <67% (unchanged and metabolites), Biliary/fecal: ~25%
Primarily via renal elimination (approximately 67% of administered dose excreted in urine as metabolites, with less than 1% as unchanged drug). The remainder is excreted in feces (approx. 25%) via biliary elimination.
