Each mL contains Active: 20 mcg of cenegermin (0.002% w/v); Inactives: disodium hydrogen phosphate anhydrous (2.87 mg), hydroxypropylmethyl cellulose (1.0 mg), L-methionine (0.01 mg), mannitol (12.22 mg), polyethylene glycol 6000 (10.0 mg), sodium dihydrogen phosphate dihydrate (1.22 mg), trehalose dihydrate (47.03 mg), Water for Injection, USP, and hydrochloric acid and/or sodium hydroxide to adjust pH.

Mechanism of Action

Nerve growth factor is an endogenous protein involved in the differentiation and maintenance of neurons, which acts through specific high-affinity (i.e., TrkA) and low-affinity (i.e. p75NTR) nerve growth factor receptors in the anterior segment of the eye to support corneal innervation and integrity.
