Pharmacodynamic and pharmacokinetic properties
The pharmacodynamics of the drug Nootropil depends on the action of its active substance piracetam. It is a cyclic derivative of gamma-aminobutyric acid (GABA). Its mechanism of action on the central nervous system is associated with the following processes:
- influence on the transmission of nerve impulses between brain cells;
- improvement of neuroplasticity due to the effect on metabolic processes;
- improvement of blood microcirculation;
- saturation of the brain with oxygen and nutrients by improving its blood supply;
- improving communication between the right and left hemispheres of the brain;
- preventing platelet aggregation;
- improvement of rheological blood parameters;
- does not cause relaxation of vascular walls.
At the same time, Nootropil has a neuroprotective and restorative effect on the brain damaged due to oxygen starvation, intoxication with alcohol or other toxic substances, or electric shock. Can be used to eliminate myoclonic syndrome due to vestibular neuronitis.
Pharmacokinetic features of piracetam:
- rapid and complete absorption through the digestive organs;
- high bioavailability (more than 99%);
- the highest concentration in the blood develops after half an hour (with intravenous administration) or after 1 hour when taken orally, in the cerebrospinal fluid - after 2-8 hours (when taking a single dose of more than 2 g);
- does not bind to blood proteins and is not metabolized in the liver;
- excreted primarily in urine unchanged;
- can accumulate in brain tissue;
- half-life from the blood lasts about 4 hours, from the cerebrospinal fluid – up to 8 hours (may be prolonged in case of kidney failure).
Piracetam is able to penetrate the blood-brain barrier, as well as the placenta.

Pharmacological properties
Pharmacodynamics
The active substance of Nootropil, piracetam, is a cyclic derivative of gamma-aminobutyric acid (GABA). It does not have organ-specific or cell-specific properties; the main mechanism of its action is due to binding to the polar heads of phospholipids and the formation of mobile piracetam-phospholipid complexes. This helps restore the two-layer structure of the cell membrane and its stability, the three-dimensional structure of membrane and transmembrane proteins and their functional properties.
Piracetam has a predominant effect on the density of postsynaptic receptors and their activity, facilitating various types of synaptic transmission at the neuronal level. Without showing a sedative or psychostimulating effect, it causes an improvement in the function of memory, attention, learning and consciousness.
By influencing red blood cells, platelets and vessel walls, it contributes to the positive dynamics of hemorheological parameters. In case of sickle cell anemia, it increases the ability of red blood cells to deform, reduces blood viscosity and prevents the formation of “coin columns”. In addition, without significantly affecting the number of platelets, it reduces their aggregation. Piracetam is able to prevent vasospasm and counteract vasospastic substances. It causes a decrease in the adhesion of red blood cells to the vascular endothelium and stimulates the production of prostacyclins by healthy endothelium.
Pharmacokinetics
There is no information on the pharmacokinetics of the solution for injection.
After taking piracetam orally, it is rapidly and almost completely absorbed from the gastrointestinal tract. The maximum concentration (Cmax) in blood plasma is 0.000084 g/ml with a single dose of 3.2 g. When using Nootropil at a dose of 3.2 g 3 times a day, Cmax in blood plasma reaches 0.000115 g/ml after 1 hour and after 5 hours in the cerebrospinal fluid. Simultaneous food intake reduces Cmax by 17% and increases the time to reach maximum concentration by up to 1.5 hours. When taking a dose of 2.4 g, Cmax in women is 30% higher than in men.
Piracetam does not bind to plasma proteins. The volume of distribution is approximately 0.6 l/kg. Selective accumulation of piracetam in the tissues of the cerebral cortex, mainly in the cerebellum and basal ganglia, parietal, frontal and occipital lobes, has been established.
The substance penetrates the blood-brain and placental barrier, overcomes the filtering membranes of hemodialysis machines. Not metabolized in the body.
Up to 80–100% of the administered dose of piracetam is excreted unchanged through the kidneys by renal filtration. The total clearance is 80–90 ml/min. The half-life (T1/2) does not depend on the route of administration and is 4–5 hours from blood plasma and 8.5 hours from cerebrospinal fluid.
In case of renal failure, T1/2 is prolonged; in case of chronic form of renal failure in the terminal stage, it can be 59 hours.
In case of liver failure, the pharmacokinetics of piracetam does not change.
Clinical and pharmacological group
The medicine belongs to the subgroup of nootropic substances.
Release form, composition and packaging
There are several medication options:
- in a mixture for parenteral use - in ampoules of 15 ml;
- in a mixture for internal use - in darkened glass bottles of 125 ml;
- in tablets - with a dosage of 1.2 grams, 20 units per pack, or 0.8 grams - 30 units per pack;
- in capsules – 60 units per pack.
All forms of the drug include the key ingredient piracetam in varying proportions. Secondary components depend on the manufacturing option of the drug:
- for parenteral administration - sodium salt of acetic acid, ethanoic acid, liquid for injections;
- in oral solution – sodium saccharin, glycerol, Caramel and Apricot flavoring, propyl hydroxybenzoate, sodium salt of acetic acid, methyl parahydroxybenzoate, water, ethanoic acid;
- in tablets - silica, polyethylene glycol, magnesium salt of stearic acid, primelose;
- in capsules - milk sugar, polysorb, magnesium salt of stearic acid, polyethylene glycol.
pharmachologic effect
Piracetam allows you to restore the double structure of the cell membrane, its stable state, which allows you to stabilize the state of transmembrane proteins and restore their functionality.
At the neuronal level, the substance improves synaptic transmission and stabilizes individual functions:
- ability to learn;
- memory indicators;
- concentration.
The drug does not have a psychostimulating or sedative effect. The substance affects vascular walls, platelets and red blood cells. For sickle cell anemia, the medicine increases the ability of red blood cells to change, lowers blood flow viscosity, and prevents the formation of pathology of coin columns. When the level of platelet aggregation decreases, the drug does not affect their number.
Pharmacokinetics
After internal administration, the active ingredient is quickly absorbed from the gastrointestinal tract, its bioavailability reaches almost 100%. Piracetam is able to accumulate in the tissues of the cerebral cortex and easily penetrates the placental and blood-brain barrier.
The substance does not undergo the metabolic process in the body and is not able to bind to protein structures in the blood plasma. The half-life is four to five hours from the bloodstream and 8.5 hours from the cerebrospinal fluid. About 80-100% of the ingredient is excreted through the kidneys in its original form.
The half-life increases in renal failure, and in hepatic failure - all processes proceed as usual.

- Metabolism: increased body weight;
- from the organ of hearing and balance: vertigo;
- allergic reactions: hypersensitivity, angioedema, anaphylactic reactions;
- dermatological reactions: itching, dermatitis, urticaria;
- other: in rare cases - hyperthermia, pain at the injection site, thrombophlebitis, arterial hypotension (against the background of intravenous administration).
Side effects
Patients who take this nootropic may experience side effects. Most often observed:
- hyperkinesia;
- drowsiness;
- nervousness, anxiety, excessive excitability;
- hallucinations;
- headaches and dizziness;
- sleep problems;
- digestive disorders (attacks of nausea, vomiting, abdominal pain, diarrhea);
- tremor of body parts;
- development of epileptic seizures;
- increased appetite (respectively weight gain);
- fluctuations in blood pressure;
- allergic reactions on the skin (rashes, itching, urticaria, dermatitis);
- extrapyramidal disorders;
- increased sexual desire (in rare cases).
Very rarely, anaphylactic reactions, hemorrhagic disorders, asthenic syndrome or a depressive state may develop.
Overdose symptoms
Signs of overdose occur when taking a dose of more than 75 g. In this case, an increase in side effects is observed. There were also cases when the patient experienced abdominal pain and bloody diarrhea.
Treatment of overdose is aimed at combating negative symptoms. Hemodialysis can be used to remove toxins.
Pharmacological interaction
The medication interacts with other active ingredients. Examples of interactions between piracetam and medications:
- Enhances the effect of thyroid hormones and antipsychotics.
- Combination with antipsychotics increases the risk of developing extrapyramidal disorders.
- Strengthens the effect on the central nervous system of drugs that have a stimulating effect on it.
- When taking anticoagulants to patients with venous thrombosis, while using high doses of piracetam, a decrease in platelet aggregation (risk of bleeding) occurs.
Nootropil and alcohol have no effect on each other.

special instructions
To relieve symptoms of side effects, in most cases it is sufficient to reduce the dose of the drug.
The effect of Nootropil on platelet aggregation should be taken into account when prescribing the drug to patients with impaired hemostasis, symptoms of severe bleeding, or during major surgical operations.
Abruptly stopping treatment for cortical myoclonus may cause attacks to recur.
When treating sickle cell anemia, a daily dose of less than 0.16 g per 1 kg of weight and irregular use of Nootropil can cause an exacerbation of the disease.
When following a hyposodium diet, the content of 0.0805 g of sodium in 24 g of oral solution should be taken into account at a dose of 0.2 g per 1 ml.
Impact on the ability to drive vehicles and complex mechanisms
During the treatment period, patients are advised to be careful when driving vehicles and complex machinery.
For impaired renal function
The use of Nootropil is contraindicated in end-stage chronic renal failure (creatinine clearance less than 20 ml/min).
Recommended dosage for patients with impaired renal function, taking into account the value of CC:
- CC above 80 ml/min: usual dose;
- CC 50–79 ml/min: 2/3 of the usual dose in 2–3 doses;
- CC 30–49 ml/min: 1/3 of the usual dose in 2 divided doses;
- CC less than 30 ml/min: once - 1/6 of the usual dose.
Calculation of the CC value can be made using the concentration of serum creatinine as a basis. When calculating CC (ml/min) for men, it is necessary to subtract the patient’s age (years) from 140, multiply the result by body weight (kg), divide by 72 and multiply by serum creatinine (mg/dL). For women, the calculation of CC is carried out similarly, only the result obtained should be multiplied by a factor of 0.85.
With long-term use of Nootropil, it is necessary to regularly monitor the functional state of the kidneys and, if necessary, adjust the dose.
Drug interactions
- Thyroid hormones: may cause confusion, irritability, and sleep disturbances;
- indirect anticoagulants: piracetam increases their effectiveness, which contributes to a more pronounced (compared to the use of indirect anticoagulants only) decrease in blood and plasma viscosity, fibrinogen concentration, platelet aggregation, von Willebrand factor;
- phenobarbital, carbamazepine, phenytoin, valproate: their maximum concentration in blood serum and total concentration in blood plasma do not change;
- ethanol: has no effect on the pharmacokinetics of piracetam, the concentration of alcohol in the blood serum does not change when taking 1.6 g of piracetam.
Piracetam does not inhibit cytochrome P450 isoenzymes.
