PHOTREXA VISCOUS (riboflavin 5’-phosphate in 20% dextran ophthalmic solution) 0.146% and PHOTREXA (riboflavin 5’-phosphate ophthalmic solution) 0.146% are intended for topical ophthalmic administration as part of corneal collagen cross-linking with the KXL System. PHOTREXA VISCOUS and PHOTREXA are supplied as: PHOTREXA VISCOUS in a 3 mL glass syringe containing sterile 1.56 mg/mL riboflavin 5’-phosphate in 20% dextran ophthalmic solution for topical administration. PHOTREXA in a 3 mL glass syringe containing sterile 1.46 mg/mL riboflavin 5’-phosphate ophthalmic solution for topical administration. PHOTREXA VISCOUS (riboflavin 5’-phosphate in 20% dextran ophthalmic solution) 0.146% is a yellow sterile buffered viscous solution containing 1.56 mg/mL riboflavin 5’-phosphate and 20% dextran . The pH of the solution is approximately 7.1 and the osmolality is 284-368 mOsm/kg. Each 1 mL of solution contains 1.64 mg of riboflavin 5’-phosphate sodium (equivalent to 1.284 mg riboflavin). Riboflavin 5’-phosphate sodium is a mixture of the sodium salts of riboflavin, riboflavin monophosphates, and riboflavin diphosphates. The inactive ingredients are dibasic sodium phosphate dihydrate, dextran, monobasic sodium phosphate dihydrate, sodium chloride, and water for injection. Sodium hydroxide and/or hydrochloric acid may be added to adjust pH.
