Description

Sepetaprost is a dual agonist of the FP and EP3 receptors. After ocular instillation, it is rapidly hydrolyzed by corneal esterases to its active metabolite, ONO-AG-367, which exhibits potent agonist activity at both FP and EP3 receptors. Unlike conventional FP receptor agonists (e.g., latanoprost), which selectively activate only the FP receptor, sepetaprost lowers intraocular pressure by simultaneously activating both pathways.
