What Type of Medicine is Кортексин?

Кортексин is defined as a neuroprotector and nootropic drug, classifying it as a bioregulator of cerebral functions intended to support the central nervous system. This prescription-only medicine, manufactured by GEROPHARM in Russia, is supplied as a sterile lyophilisate for solution preparation for subsequent intramuscular injection. The complex is a neurotrophic drug comprising neuropeptides, amino acids, and trace elements.

Is Кортексин a Natural or Synthetic Preparation?

The active core of Кортексин is a unique biological preparation of low-molecular water-soluble polypeptide fractions derived from the cerebral cortex of cattle or pigs. This makes it a multicomponent peptide drug, distinct from synthetic chemicals, containing various oligopeptides, L-amino acids, and essential trace elements. The peptides in Кортексин are capable of crossing the blood-brain barrier and binding to receptors, supporting the basis for its effects.

What is the General Purpose of this Bioregulator?

The overall purpose of this bioregulator is to provide neurotrophic support and neuroprotection, aiming to increase the functional capacity and resilience of the brain. Its actions include stabilizing neuronal membranes and demonstrating an antioxidant effect to mitigate cellular damage. The medicine is associated with a favourable effect on cerebral mnestic and cognitive functions across different patient groups. By modulating critical processes, the medicine is intended to aid the restoration and maintenance of compromised cerebral functions in the face of various stresses or pathologies.

Possible Side Effects and Safety Information

The safety profile for this medicine is based on classifications defined in official government regulatory documents. All officially documented adverse reactions associated with the use of Кортексин are classified as Very Rare, meaning they are expected to occur in less than 1 out of every 10,000 users.


Adverse Reaction Categories

Side effects are categorized by the System-Organ Class (SOC) where effects may manifest. These classes include Immune System Disorders (hypersensitivity), Nervous System Disorders (e.g., headache, dizziness, somnolence, insomnia), Cardiac Disorders (e.g., tachycardia, arrhythmia), and Skin and Subcutaneous Tissue Disorders (e.g., rash, pruritus). Reactions at the injection site are also listed under General Disorders.

Officially documented Serious Adverse Reactions classified as Very Rare include Anaphylactic Shock and Angioedema, which are forms of severe hypersensitivity.


Population-Specific Safety and Restrictions

  • Pregnancy and Lactation: The medicine is contraindicated during pregnancy and breastfeeding due to a lack of sufficient clinical data regarding its use in these populations.
  • Pediatric Use: The official label states that using Lidocaine as a solvent when preparing the solution for administration in children is not recommended due to the increased risk of severe adverse reactions associated with the solvent itself.
  • Functional Constraints: Patients who experience central nervous system side effects such as dizziness or somnolence must refrain from driving or operating complex machinery until these effects have resolved. The solution should also not be mixed with other drug solutions.

Overdose and Emergency Response

Overdose and When to Seek Help

The official prescribing information for Кортексин defines its overdose profile through a documented absence of clinical reports. According to the national regulatory authority's instructions for use, there have been no cases of overdose reported with this medicinal product. This regulatory fact forms the basis of the official guidance for this section.

Documented Manifestations and Outcomes

Due to the lack of reported cases, the official labeling does not specify any associated clinical signs, symptoms, or laboratory findings that may constitute an overdose presentation. Consequently, no specific severe or life-threatening outcomes have been formally documented or categorized in the regulatory material. The documentation is silent on any specific physiological systems affected by excessive administration.

Emergency Actions and Procedures

No specific immediate emergency actions or procedural steps are mandated in the overdose section of the official instructions. Because no clinical presentation is documented, the labeling does not define specific conditions or symptom clusters that would trigger an explicit regulatory requirement to seek urgent medical attention. Furthermore, the official prescribing information does not specify the existence of an antidote, nor does it mandate specific supportive treatments or continuous monitoring procedures for overdose.

Population-Specific Risks None documented

Therapeutic Uses of Кортексин

What Кортексин treats: Main Uses and Benefits

The primary therapeutic use of Кортексин is to provide supportive benefit across several domains of central nervous system function, generally in clinical settings marked by compromised cerebral capacity. Its use is associated with symptomatic management across therapeutic areas involving supportive neurofunctional care.

The medication is commonly applied across conditions presenting with acute episodes and recurrent manifestations, including the acute period of ischemic stroke, the consequences of Traumatic Brain Injury (TBI), and chronic dyscirculatory encephalopathy. It is also considered relevant for easing symptoms in pediatric contexts, such as those related to developmental speech delay and perinatal CNS lesions.

The supportive therapy is relevant for easing symptoms and contributes to improved day-to-day comfort during symptomatic periods. One aspect of its therapeutic profile indicates:

“The application is relevant when supportive symptom management is appropriate and may assist with easing the overall symptom load.”

It is generally used to address symptom clusters that may become intense or disruptive, particularly Intellectual-Mnestic Dysfunctions (impaired attention and memory) and generalized symptoms like asthenoneurotic syndrome (chronic mental fatigue).

What should I know about interactions with other medicines?

Interactions with other medicines and products

Pharmacological Interaction Profile

Official regulatory documents indicate that the medicine Кортексин does not exhibit significant pharmacological interaction patterns with other medicinal products. The drug is defined by its lack of documented metabolic conflicts, meaning there are no officially stated interactions related to Cytochrome P450 enzymes, drug transporters, or other specific pharmacokinetic pathways. The official labeling states that it may be included as a component in complex therapeutic regimens without concern for typical drug-drug conflicts.

Restrictions on Administration and Preparation

Despite the absence of significant pharmacological interactions, the official regulatory information details specific physical and procedural restrictions that govern its administration:

  • Physical Incompatibility: The prepared solution of the lyophilisate must not be mixed with other medicinal products or solutions. This necessitates that the medicine must be administered separately from other injectable medications, which functions as a mandatory timing rule.
  • Population-Specific Solvent Restriction: A specific constraint applies to reconstitution in the pediatric population. The use of Lidocaine (Procaine) as a solvent is not recommended in children. This restriction is documented because using Lidocaine for reconstitution in this population is officially associated with an increased severity of adverse reactions.

No official regulatory data documents specific interactions with food, alcohol, herbal products, or dietary supplements.

Mechanism of Action

Кортексин, a polypeptide complex, is observed to cross the blood-brain barrier and demonstrates selective accumulation in cortical neurons.

Molecular and Intracellular Pathways

The constituent peptides exhibit multitargeted interactions with various neuronal receptors and enzymes. Specifically, in vitro binding assays indicate interaction with AMPA and kainate receptors, acting as non-competitive binders/modulators of glutamatergic signaling. It also interacts with GABAA1 and metabotropic glutamate receptors (mGluR1, mGluR5), thus modulating both excitatory and inhibitory neurotransmission.

Intracellularly, it engages in anti-apoptotic signaling by inhibiting caspase-8 activity, which reduces the cascade leading to programmed cell death. The drug also modulates mitochondrial function by stabilizing the mitochondrial membrane potential (Delta Psim) and initiating the restoration of ATP synthesis within nerve cells. Furthermore, Кортексин influences gene expression of neurotrophic factors, including Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF), leading to increased neuronal plasticity.

System-Level Physiological Consequences

These molecular effects result in system-level neuroprotection and neurotrophic modulation, contributing to the overall stabilization of neuronal functional integrity and modulation of synaptic efficacy within the central nervous system.

Dosage and Administration Information

Official Administration Guidelines for Кортексин

Кортексин (Cortexin) is a lyophilized powder for solution and is intended exclusively for parenteral administration. This injectable medication must be prepared and administered strictly according to the prescribing physician's instructions and the official product leaflet.


Administration Scope

Feature Official Requirement
Route of administration Intramuscular (IM) injection is the only route of administration currently registered for routine use.
Preparation requirements The lyophilized powder must be reconstituted prior to injection. The required diluents are 0.5% Procaine solution (for pain relief), 0.9% Sodium Chloride solution, or sterile water for injection.
Dosing Frequency The injection is administered once daily (QD). The standard duration for a course of treatment is 10 days of consecutive daily injections.
Age-Group Rules Dosing is adjusted by patient size. Pediatric patients weighing less than 20 kg typically receive a lower dose (e.g., 0.5 mg/kg body weight), while those over 20 kg generally receive the adult dose (e.g., 10 mg), as determined by a physician.
Timing & Missed Dose Administration should occur once daily, preferably at the same time each day to maintain consistency. Specific official instructions on managing a missed dose (e.g., whether to skip or administer late) should be followed as detailed by the prescribing professional.

Procedural Steps

The required sequence involves reconstituting the powder, drawing the solution, and administering the injection. The process of reconstitution is critical: the specified amount of sterile diluent must be added to the vial, and the contents gently mixed until the powder is fully dissolved before being drawn up for the intramuscular injection.

Recent Clinical Evidence

Evidence for use in Chronic Cerebral Ischemia and Dyscirculatory Encephalopathy

Research exploring the use of this medicine in adults with chronic cerebral ischemia (CCI) has included randomized controlled trials (RCTs) and various multicenter clinical studies. These studies primarily examined middle-aged and older adults, monitoring functional neurological deficits, cognitive scores (e.g., attention and memory), and emotional status. Studies reported patterns observed in changes to these measures, including patients with post-COVID syndrome presenting with fatigue symptoms. The certainty of the findings in this area remains low. Key limitations noted include a limited number of eligible high-quality RCTs and multiple concerns regarding risk of bias.

Evidence for use in Pediatric Cognitive and Neurofunctional Disorders

Studies have explored pediatric populations, predominantly children aged three to seven years, diagnosed with conditions such as developmental speech delay (DSD) and asthenoneurotic syndrome. Research evaluated age-appropriate cognitive function and psychomotor skill restoration. Clinical reports documented observed changes measured during the study period, including patterns related to reported measurements of change in active vocabulary volume in children with DSD. The certainty of evidence for these pediatric findings remains low, relying mainly on specific regional study contexts.

Long-term Follow-up and Research Limitations

The majority of research focuses on short-term symptom changes; follow-up durations were typically limited (10–30 days). Consequently, long-term effects are not fully established, and the durability of any observed functional changes is not well characterized by existing evidence. While older adults and specific pediatric groups have been studied, data for certain groups remain insufficient, and findings regarding complex patient profiles are generally uncertain. The overall evidence quality varies across studies, and the certainty remains low for the evidence supporting the use of this class of medicine.
