N-Acetylcarnosine Prevents and Reverses Cataracts

According to the latest estimates of the World Health Organization, about 284 million people are visually impaired worldwide: 39 million are blind and 245 have low vision.

In a new report, HPLC analysis was used to search the pathways of ocular metabolic activities for a 1% N-acetylcarnosine eye drop solution and the bioactivation of this molecule for the promotion of transcorneal uptake of L-carnosine in the aqueous humor.1 When a meta-analysis of phase 2 of a randomized double-blind placebo-controlled clinical trial data was conducted, the intraocularly absorbed L-carnosine demonstrated a number of pharmacological mechanisms for the prevention and reversal of cataracts.

The systemic absorption of L-carnosine results in hypothalamic activation that regulates neuronal functions such as the promotion of sensory input in the primary vision perceptual pathway. The discovery of naturally-occurring carnosine derivatives such as N-acetylcarnosine have been found to be an effective treatment for sight-threatening eye disorders.
