Semax is a nootropic drug with a pronounced antioxidant, cerebroprotective and antihypoxic effect.

Release form and composition

Semax is produced in the form of nasal drops of 0.1% and 1%: transparent, colorless (3 ml in vials, in a cardboard box 1 vial complete with a pipette stopper).

Active ingredient: methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline, in 1 ml drops - 1 or 10 mg.

Excipients: methyl parahydroxybenzoate, purified water.

Pharmacological properties

Pharmacodynamics

Semax is a synthetic peptide drug, the active component of which is an analogue of a fragment of adrenocorticotropic hormone (ACTH _4-10) methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline. This substance completely lacks hormonal activity. All amino acids included in it belong to the L-form.

Methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline is distinguished by an original mechanism of neurospecific action on the central nervous system. Semax is a synthetic analogue of corticotropin, characterized by nootropic properties and practically not showing hormonal activity. The drug affects the processes associated with learning and memory formation. Semax promotes concentration of attention during training and information collection, ensures the adaptation of the body to anesthesia, cerebral ischemia, hypoxia and other traumatic influences, improves the consolidation of the memory footprint in patients with cerebrovascular diseases (including discirculatory encephalopathy), as well as after traumatic brain injury and neurosurgical interventions.

The drug does not exhibit toxic properties both with single and multiple administration. Also, mutagenic, teratogenic, embryotoxic and allergic properties are uncharacteristic for it. Methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline does not have a local irritating effect.

Pharmacokinetics

The absorption of methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline occurs from the nasal mucosa, and up to 60–70% of the substance is fully absorbed. It is distributed at a high speed to all organs and tissues, and also penetrates the blood-brain barrier. When it enters the bloodstream, the drug undergoes rapid biotransformation and is excreted from the body through the kidneys.

Reviews about Semax
