- Latanoprost, an analog of prostaglandin F2alpha, is a prodrug used to reduce elevated intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension. Studies have shown that latanoprost administered once daily is at least as effective as timolol in lowering intraocular pressure.12 When latanoprost and timolol were used in combination, a complete or almost complete additive effect in reducing intraocular pressure has been observed. Treatment has been associated with increased pigmentation of the iris, periorbital tissue (eyelid) and eyelashes.
- Latanoprost is a selective agonist at a subtype of prostaglandin receptors known as the FP receptor. By acting on the FP receptor, latanoprost increases the outflow of aqueous humor thereby reducing intraocular pressure. According to the manufacturer, studies in both animals and man suggest that increased uveoscleral outflow is the primary mechanism of action.
