Usage:
Calcium dobesilate is an antioxidant that has been used to treat diabetic retinopathy, in which it slows progression of the disease during long-term oral treatment by reducing microvascular permeability, leading to improved visual acuity. It not only acts as an antioxidant but also stimulates endothelial production of nitric oxide.
