Verosudil is primarily used in the treatment of ocular conditions, particularly those involving elevated intraocular pressure (IOP). It is commonly prescribed for managing glaucoma and ocular hypertension. The compound works by inhibiting Rho kinase, which helps to relax the trabecular meshwork and increase the outflow of aqueous humor, thereby reducing pressure within the eye. This mechanism makes it effective in preventing optic nerve damage and preserving vision in patients with these conditions. It is often administered as an eye drop, ensuring targeted delivery and minimal systemic side effects. Regular use as directed by a healthcare provider can significantly improve outcomes for individuals at risk of vision loss due to high IOP.
