Rho kinase inhibitors (rho-associated protein kinase inhibitor or ROCK inhibitor) are a series of compounds that target rho kinase (ROCK). Clinical trials have found that inhibition of the ROCK pathway contributes to the cardiovascular benefits of statin therapy. Furthermore, ROCK inhibitors may have clinical applications for anti-erectile dysfunction, antihypertension, and tumor metastasis inhibition. More recently they have been studied for the treatment of glaucoma.
