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 increases the growth of eyelashes by prolonging the anagen (growth) phase and increasing the number of hairs. The exact molecular mechanism is thought to involve binding to prostamide receptors, leading to modulation of intracellular signaling pathways that regulate hair follicle cycling.
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.
One drop applied to the upper eyelid margin at the base of the eyelashes once daily using the provided sterile applicators.
One drop in the affected eye(s) once daily in the evening. Ophthalmic solution 0.004% (travoprost 0.04 mg/mL).

The terminal elimination half-life of bimatoprost in plasma is approximately 45 minutes (range 30-60 minutes) after topical ocular application in humans. This short half-life reflects rapid systemic clearance, but the drug's ocular hypotensive effect persists for 24 hours due to tissue binding.
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 renal elimination of metabolites; less than 5% of unchanged bimatoprost is excreted in urine. Fecal excretion accounts for approximately 25% of the dose, predominantly as metabolites. Biliary excretion is minimal.
Primarily eliminated via hepatic metabolism; renal excretion of metabolites accounts for approximately 20% of the dose; fecal excretion is minimal.
