Riboflavin sodium phosphate is widely used in the pharmaceutical and healthcare industries. It is primarily employed as a source of vitamin B2, essential for treating deficiencies that can lead to conditions like ariboflavinosis, characterized by sore throat, redness of the tongue, and cracked lips. In ophthalmic applications, it is utilized in corneal cross-linking procedures to treat keratoconus, a condition where the cornea thins and bulges into a cone shape. The compound acts as a photosensitizer when exposed to ultraviolet light, strengthening the corneal collagen and improving vision stability. Additionally, it is incorporated into multivitamin formulations and dietary supplements to support overall health, energy metabolism, and cellular function. Its water-soluble nature makes it suitable for intravenous administration in clinical settings, particularly for patients with malabsorption issues.
