Pirenoxine is a preparation of 1-hydroxy-5-oxo-5H-pyrido(3,2-α)-phenoxazine-3-carboxylic acid, a compound having a chemical structure similar to xanthommatin, an eye pigment of the insect, with a pyridophenoxazone nucleus.

The solvent is isotonic, buffered solution containing 0.02% methylparaben, 0.01% propylparaben and 0.0001% thimerosal as preservatives.

Mechanism of action
Though the pathogenesis of cataract has not yet been clearly determined, conversion of water-soluble protein in the lens to insoluble protein by quinone substances produced as the result of abnormal metabolism of aromatic amino acid, is said to be responsible for cataract according to "Quinoid Theory" established as the result of biochemical study on lens protein in the Dept. of Ophthalmology, Osaka University Medical School. Pirenoxine is found to competitively inhibit the action of the quinone substances. Extensive experiments, both basic and clinical, have proven that this agent prevents the progress of cataract.

Ophthalmic soln 0.75 mg/tab x 15 mL x 1's.
