Pharmacological properties

Pharmacodynamics

Complex drug that improves energy metabolism of the lens. Cytochrome C plays an important role in biochemical redox processes in the eyeball tissues and is an antioxidant. Adenosine is a precursor of adenosine triphosphate (ATP) and takes part in the metabolic processes of the lens. Nicotinamide stimulates the synthesis of nicotinamide dinucleotide (NAD), a cofactor of dehydrogenases.

Pharmacokinetics

When used topically, cytochrome C is not absorbed into the systemic bloodstream and is fully metabolized in the body. The breakdown of cytochrome C follows the same metabolic pathways as the breakdown of amino acids, and heme, which is broken down to bilirubin, is excreted in the bile.

Adenosine passes freely through the cornea. The half-life of adenosine from plasma is less than one minute, it is metabolized in almost all tissues to form inosine, xanthine and urate, which are freely excreted with the urine. Ribose, which is a constituent of adenosine, is metabolized to glyceraldehyde-3-phosphate, then to pyruvate and is burned in the Krebs cycle.

Nicotinamide is partially metabolized to nicotinic acid. Both of these compounds are methylated to N-methylnicotinamide, which is further broken down in the liver. Metabolites and unchanged nicotinamide are excreted in the urine.

Special Instructions

Benzalkonium chloride, which is often used as a preservative in ophthalmic products, can cause keratopathy and/or toxic ulcerative keratopathy. Because it contains benzalkonium chloride, close monitoring is required for frequent or prolonged use in patients with dry eye syndrome or in cases of corneal damage. Benzalkonium chloride may discolor soft contact lenses. Soft contact lenses should be removed before application and put on again 15 minutes after dosing.

Influence on driving and operating ability

Patients who have transient eye irritation after injection should not drive a vehicle or operate machinery, machines, or any other equipment requiring good visual acuity immediately after using the eye drops.

Contraindications

Individual hypersensitivity to the drug components, children under 18 years of age (due to the lack of data on the effectiveness and safety of the drug in children and adolescents under 18 years).

Side effects

Ocular side effects: transient burning and tingling of the eyes, allergic conjunctivitis, contact dermatitis.

Systemic side effects are extremely rare. Short-term nausea, arterial hypotension, dizziness and shortness of breath may be observed. Nicotinic acid has a vasodilator effect and may cause a feeling of fever, fainting, and a throbbing sensation in the temples.

Pregnancy use

There is no sufficient experience of using the drug during pregnancy and breastfeeding. It is possible to use the drug for treatment during pregnancy and during breastfeeding if the expected therapeutic effect for the mother justifies the potential risk for the fetus and child.
