Clinical Overview
Vitamin A Capsules (25,000 IU, 600mcg) is a fat-soluble retinoid on the WHO Model List of Essential Medicines. Retinol is converted to retinal (essential for rhodopsin formation in retinal rod cells for night vision) and retinoic acid (which regulates gene expression for epithelial differentiation, mucous membrane integrity, and cell-mediated immunity). Indicated for prevention and treatment of vitamin A deficiency, night blindness (nyctalopia), xerophthalmia, keratomalacia, and supportive treatment during measles in children.
