Nootropics. Пирацетам – циклическое производное GABA. A direct impact on the brain. Lutset® improves cognitive (cognitive) processes, such as the ability to learn, memory, Attention, ability to memorize, and also enhances mental performance, without the development of sedation and psychostimulant effects.
It affects the central nervous system in different ways: It changes the propagation speed of the excitation in the brain, neuronal plasticity and improves metabolic processes in neuronal cells. It improves communication between the hemispheres of the brain and synaptic conductance in neocortical structures, enhances mental performance, improves cerebral blood flow.
Lutset® improves microcirculation in the brain, acting on the rheological characteristics of the blood, and causes vasodilatory action. Lutset® It inhibits platelet aggregation and restores the elastic membrane of erythrocytes, as well as the ability of the latter to the passage through the microvasculature. It reduces adhesion of red blood cells. At a dose of 9.6 Mr. reduces levels of fibrinogen and von Willebrand factor in the 30-40% and prolongs bleeding time.
Lutset® It provides a protective and restorative effect in violation of the functions of the brain as a result of hypoxia, intoxication or injuries. It reduces the severity and duration of the vestibular nystagmus.
Absorption
After oral administration piracetam is rapidly and almost completely absorbed from the gastrointestinal tract, Cmax plasma levels achieved after 1 no. Bioavailability is about 100%. After oral administration of a single dose 2 г Cmax is 40-60 ug / ml, which is achieved in plasma 30 minutes, and after 5 h in the cerebrospinal fluid.
Distribution and metabolism
Vd is about 0.6 l / kg. Piracetam selectively accumulates in the tissues of the cerebral cortex, primarily in the frontal, parietal and occipital lobes, in the cerebellum and basal ganglia.
It binds to plasma proteins.
Piracetam penetrate the BBB and placental barrier. Do not metabolized in the body.
Deduction
T1/2 from plasma is 4-5 no, T1/2 из спинномозговой жидкости – 8.5 no.
Выводится почками в неизмененном виде – 80-100%, by renal filtration. Renal clearance of piracetam in healthy volunteers is 86 ml / min.
Pharmacokinetics in special clinical situations

At cortical myoclonus Treatment begins with a dose of 7.2 g / day, every 3-4 increase the dose of the day 4.8 g / d to a maximum dose 24 g / day. Treatment continued throughout the period of illness. Every 6 months should attempt to reduce the dose or stop the drug, gradually reducing the dose by 1.2 g every 2 day in order to prevent attack. If there is no effect or a minor therapeutic effect of treatment is stopped.
When treating comatose states, and the difficulties of perception in people with injuries introducing drug / m or in / at an initial dose of 9-12 g / day, maintenance dose - 2.4 g / day. Treatment continues for at least 3 weeks.
Babies to correcting learning disabilities administered orally at a dose 3.2 g / day. Treatment continues throughout the school year.
In patients with impaired renal function requires correction mode depending on the spacecraft.
| The degree of renal insufficiency | CC (ml / min) | Dose |
| Norm | >80 | The usual dose |
| Easy | 50-79 | 2/3 normal dose 2-3 admission |
| Central | 30-49 | 1/3 normal dose 2 admission |
| Weight | <30 | 1/6 normal dose, single |
| End-stage | – | contraindicated |
In elderly patients correcting the dose in the presence of renal failure and prolonged treatment is necessary to monitor renal function.
In patients with impaired liver function correction dosing regime is not required.

Piracetam crosses the placental barrier, excreted in breast milk. Concentration piracetam blood reaches neonates 70-90% on its concentration in the blood of the mother.
If necessary, use during lactation should stop breastfeeding.
Due to the influence of piracetam on platelet aggregation, caution should be prescribed to patients with impaired hemostasis, during major surgery or in patients with symptoms of severe bleeding.
In the treatment of cortical myoclonus should avoid abrupt discontinuation, which may cause the resumption of seizures.

Effects on ability to drive and operate machinery
Taking into account the possible side effects, the patient should be careful when driving or operating machinery.
Treatment: immediately after oral administration can wash out the stomach or cause an artificial vomiting. Symptomatic therapy, which may include hemodialysis. No specific antidote. The effectiveness of hemodialysis for piracetam 50-60%.
While the use of thyroid extract can be increased irritability, disorientation and sleep disorders.
There was no interaction with clonazepam, phenytoin, fenoʙarʙitalom, sodium valproate.
Piracetam high doses (9.6 g / day) acenocoumarol improves patients with venous thrombosis (It noted a marked reduction in the level of platelet aggregation, fibrinogen level, von Willebrand factor, blood and plasma viscosity in comparison with the use of only acenocoumarol).
The ability to change under the influence of piracetam pharmacodynamics of other drugs is low, tk. 90% the drug is excreted unchanged in the urine.
In vitro, piracetam does not inhibit CYP1A2 isoenzymes, 2AT 6, 2C8, 2C9, 2C19, 2D6, 2E1 and 4A9 / 11 in a concentration of 142, 426 and 1422 ug / ml. At a concentration of piracetam 1422 ug / ml was a slight inhibition of CYP2A6 (21%) and 3A4 / 5 (11%). However, the level of the two isoenzymes Ki sufficient in excess 1422 ug / ml. Therefore, metabolic interaction with other drugs is unlikely.
Receiving a dose of piracetam 20 mg / day did not change the level of the peak curve and the concentration of antiepileptic drugs in serum (Carbamazepine, phenytoin, phenobarbital, valproate) in patients with epilepsy, receiving the drug at constant dose.
Joint reception with ethanol had no effect on the level of concentration in the serum of piracetam, ethanol concentration in serum did not change when receiving 1.6 g piracetam.
