BIMATOPROST vs LATISSE
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 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.
One drop of 0.01% or 0.03% ophthalmic solution instilled into the affected eye(s) once daily in the evening.
One drop applied to the upper eyelid margin at the base of the eyelashes once daily using the provided sterile applicators.

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
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.
Renal: <67% (unchanged and metabolites), Biliary/fecal: ~25%
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.
