Avost Eye Drops
Avost, an isopropyl ester prodrug, is a synthetic prostaglandin F2 alpha analogue that is rapidly hydrolyzed by esterases in the cornea to its biologically active free acid. The travoporst free acid is potent and highly selective for the FP prostanoid receptor.
Avost free acid is a selective FP prostanoid receptor agonist and is believed to reduce intraocular pressure by increasing the drainage of aqueous humor, which is done primarily through increased uveoscleral outflow and to a lesser extent, trabecular outflow facility.
Avost Eye Drops is used for the reduction of elevated intraocular pressure in patients with open-angle glaucoma or ocular hypertension who are intolerant of or insufficiently responsive to another intraocular pressure lowering medication, as monotherapy or as adjunctive therapy.
Avost is also used to associated treatment for these conditions: Increased Intra Ocular Pressure (IOP)
