Description of the active substance :.
This information is a reference and it is not enough that the drug was prescribed by a doctor.
Antipsychotic agent (antipsychotic).
It is assumed that the therapeutic effect of aripiprazole in schizophrenia is due to a combination of partial agonistic activity against dopamine D 2 and serotonin 5-HT 1a receptors and antagonistic activity against serotonin 5-HT 2receptors.
Aripiprazole has a high affinity in vitro
to dopamine D 2 - and D 3 receptors, serotonin 5-HT 1a - and 5-HT 2a receptors and moderate affinity for dopamine D 4 -, serotonin 5-HT 2c - and 5-HT 7 -,? 1- adrenoreceptors and histamine H 1 -receptors. Aripiprazole is also characterized by moderate affinity for the sites of serotonin reuptake and lack of affinity for muscarinic receptors.
After ingestion, aripiprazole is rapidly absorbed from the digestive tract.
C max in plasma is achieved in 3-5 hours. Absolute bioavailability is 87%. Eating food does not affect the bioavailability of aripiprazole.
C ss is achieved after 14 days.
Cumulation of the drug with multiple admission is predictable. The pharmacokinetics of aripiprazole in the equilibrium state are proportional to the dose. There were no daily fluctuations in the distribution of aripiprazole and its metabolite dehydroaripiprazole.
Aripiprazole is intensively distributed in tissues, V d is 4.9 l / kg.
At a therapeutic concentration of more than 99%, aripiprazole binds to serum proteins, mainly with albumin.
It has been established that dehydroaripiprazole, the main metabolite in human plasma, has the same affinity for dopamine D 2 receptors as aripiprazole.

Aripiprazole undergoes pre-systemic metabolism only to a minimal extent.
Aripiprazole is metabolized in the liver in three ways: by dehydrogenation, hydroxylation and N-dealkylation. In vitro dehydrogenation and hydroxylation of aripiprazole occurs under the action of isoenzymes CYP3A4 and CYP2D6, N-dealkylation - CYP3A4.
In the equilibrium state, the AUC of dehydroaripiprazole is about 39% of the aripiprazole AUC in plasma.

The mean T 1/2 of aripiprazole is about 75 hours.

After a single administration of labeled 14C aripiprazole, approximately 27% and 60% of radioactivity is determined in urine and feces, respectively.
Less than 1% of unchanged aripiprazole is detected in the urine and approximately 18% of the dose taken is unchanged with feces. The total clearance of aripiprazole is 0.7 ml / min / kg, mainly due to excretion by the liver.
Treatment of acute attacks of schizophrenia, supporting the therapy of schizophrenia.

Senile dementia, lactation, children and adolescents under 18, hypersensitivity to aripiprazole.

Adequate and strictly controlled clinical studies of safety of use in pregnancy have not been conducted.
Aripirazole can be used in pregnancy in cases where the potential benefit of therapy for the mother exceeds the possible risk to the fetus.
It is not known whether aripirazole is excreted in human milk.
The use of aripiprazole during lactation (breastfeeding) is contraindicated.
In experimental studies, it has been shown that aripiprazole is secreted with milk in lactating rats.

Contraindication: children and adolescence under 18 years.

Use with caution in patients with cardiovascular diseases (IHD, including myocardial infarction, chronic heart failure, conduction disorders), conditions predisposing to arterial hypotension (dehydration, hypovolemia and taking antihypertensive drugs) in connection with the possibility of development orthostatic hypotension;
in patients with cerebrovascular disease, with convulsive seizures or suffering from diseases in which convulsions are possible; in patients with an increased risk of hyperthermia (for example, with intense physical exertion, overheating, anticholinergic drugs, dehydration due to the ability of neuroleptics to disrupt thermoregulation); in patients with an increased risk of aspiration pneumonia due to the risk of impaired motor function of the esophagus and aspiration; in patients with obesity, with a history of diabetes mellitus; reception of funds with m-cholinoblocking activity.
Propensity to suicidal thoughts and attempts is characteristic for psychoses, therefore at carrying out of medicinal therapy careful medical observation is necessary.

The risk of developing tardive dyskinesia increases with the duration of therapy with antipsychotics, so when aripiprazole arises with symptoms of tardive dyskinesia, you should reduce its dose or cancel it.
After the withdrawal of therapy, these symptoms may temporarily increase or even appear for the first time.
In the treatment of neuroleptics, incl.
aripiprazole may develop ZNS, which manifests hyperpyrexia, muscle rigidity, mental disorders and instability of the autonomic nervous system (irregular heartbeats and blood pressure, tachycardia, sweating and cardiac arrhythmias). In addition, sometimes there is an increase in activity of CK, myoglobinuria (rhabdomyolysis) and acute renal failure. In case of symptoms of NSA or unexplained fever, all antipsychotics, incl. aripyrazole, it is necessary to cancel.
Hyperglycemia, sometimes expressed and associated with ketoacidosis, which can lead to hyperosmolar coma and even death, has been noted in patients taking atypical antipsychotics.
Although the association between the admission of atypical antipsychotics and hyperglycemic disorders is unclear, patients who have diabetes mellitus should regularly perform a blood glucose test when taking atypical antipsychotics. Patients who are at risk for diabetes (obesity, having diabetes in the family) should take the blood glucose level at the beginning of the course and periodically during the administration of the drug when taking atypical antipsychotics. Any patient taking atypical antipsychotics needs constant monitoring of symptoms of hyperglycemia, including increased thirst, frequent urination, polyphagia, and weakness.
Impact on the ability to drive vehicles and manage mechanisms

As with the appointment of other neuroleptics, when appointing aripiprazole, the patient should be warned about the dangers of working with moving mechanisms and driving.

There are different ways of metabolism of aripiprazole, including.
with the participation of enzymes CYP2D6 and CYP3A4. In studies in healthy humans, potent inhibitors of CYP2D6 (quinidine) and CYP3A4 (ketoconazole) reduced aripiprazole clearance when ingested by 52% and 38%, respectively (the dose of aripiprazole should be reduced while being used with CYP3A4 and CYP2D6 inhibitors).
Receipt of aripiprazole at a dose of 30 mg concomitantly with carbamazepine, a powerful inducer of CYP3A4, was accompanied by a decrease in C max and AUC of aripiprazole by 68% and 73%, respectively, and by a decrease of C max and AUC of its active metabolite dehydroaripiprazole by 69% and 71%, respectively.
You can expect a similar effect on other powerful inductors CYP3A4 and CYP2D6.
