A Khavinson-class retina and eye bioregulator. Marketed as eye drops for retinal function and age-related visual decline. As with the whole class, the evidence is Russian-language, unreplicated, and does not meet the standard applied elsewhere in this database.
Peptide bioregulators are built on a specific claim: that very short peptides extracted from — or synthesised to match — a particular organ can travel to that same organ and restore its normal function as it ages. Normoftal is the retinal version, sold as eye drops and promoted for age-related macular changes and general visual function. The proposed route is direct interaction with DNA to switch tissue-specific genes back on. That mechanism has been demonstrated to the satisfaction of the group that proposed it and essentially nobody else.
A retinal peptide preparation formulated for topical ocular use, reported by the originating group to influence retinal pigment epithelium function and photoreceptor survival in animal models. The class hypothesis holds that di-, tri- and tetrapeptides penetrate cell and nuclear membranes and bind directly to specific promoter sequences in double-stranded DNA, modulating tissue-specific transcription — a mechanism supported by molecular modelling and gel-shift work from the originating institute but not independently corroborated. Products are marketed in two chemically distinct forms: "Cytomax" preparations, which are peptide fractions extracted from the corresponding animal organ, and "Cytogen" preparations, which are defined synthetic short peptides. Published clinical evaluation is limited to small Russian studies, generally without blinding, placebo control or independent statistical review.
Research areas
Every protocol below is reproduced from a published study or approved labelling, with its source named. These are records of what was studied — not recommendations, and not a suggestion that any of them is appropriate for any person.
| Protocol as reported | Source |
|---|---|
| One to two drops in each eye, two or three times daily, taken as a 10–30 day courseThis describes what is marketed, not a validated regimen. No dose-finding study has been published. | Russian supplier protocol |
Small Russian studies from the originating institute. No registered Western trials, no independent replication, and no published randomised placebo-controlled evidence meeting international standards.
There is no controlled evidence that it does anything for AMD, and AMD has treatments with real trial support. Substituting an unproven eye drop for anti-VEGF therapy in wet AMD would be a serious mistake.
