Nedsætter det intraokulære tryk ved at øge outflowet af kammervæske via trabekelværket og de uveosklerale veje.
Travoprost, a prostaglandin F2α analogue, is a full agonist which is highly selective and has a high affinity for the prostaglandin FP receptor, and reduces the intraocular pressure by increasing the outflow of aqueous humour via trabecular meshwork and uveoscleral pathways.
