Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Latanoprost is a prostaglandin F2α analogue that reduces intraocular pressure by increasing the outflow of aqueous humor through the uveoscleral pathway.
One drop of 0.01% ophthalmic solution in the affected eye(s) once daily in the evening.
One drop (1.5 mg/mL) in the affected eye(s) once daily in the evening.

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.
Terminal elimination half-life of latanoprost acid is approximately 17 minutes; clinically, intraocular pressure reduction persists for 24 hours due to long receptor residence time.
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.
Renal (approximately 50% as metabolites, <1% as unchanged drug); biliary/fecal (remainder).
