Description Ripasudil (Glanatec TM, Kowa Pharmaceutical), a close derivative of fasudil, is another Rho kinase inhibitor approved in Japan at the end of 2014 for the treatment of glaucoma and ocular hypertensionwhen other therapeutic agents are not effective or cannot be administered. Additionally, ripasudil has been tested in diabetic retinopathy clinical trials and shown to promote corneal endothelial cell proliferation, endothelium regeneration, and wound healing.
