Catrix is a sterile eye drops containing Adenosine, Nicotinamide, Cytochrome C and Sodium Succinate. Cytochrome C helps in the oxidative phosphorylation for synthesizing ATP from ADP. Sodium Succinate (intermediate substance) promotes the production of ATP. Adenosine plays essential role in producing energy required for the vital function of the lens. Nicotinamide is involved in the process of creating ATP.
