Postoperative nausea and vomiting.

Adultsto prevent postoperative nausea and vomiting, the drug can be administered orally at 16 mg at 1:00 before anesthesia. The maximum daily dose of ondansetron is 32 mg.

Children.in this reading, it is recommended to use ondansetron as an injection solution.

for all types of therapy.

elderly Patients.

there is no need to change the dose in patients over 65 years of age.

patients with renal insufficiency.

there is no need to change the dosage regimen or the route of administration of the drug to patients with impaired renal function.

patients with moderate hepatic insufficiency.

in patients with moderate hepatic impairment, the clearance of ondansetron decreases significantly, and the half - life from blood serum increases. For such patients, the maximum daily dose should not exceed 8 mg.

Patients with a metabolic disorder sparteine/debrisoquine.

the half-life of ondansetron in patients with impaired metabolism sparteine and debrisoquine does not change. In such patients, repeated use leads to the same concentration of the drug in patients with intact metabolism. Therefore, there is no need to change the dosing regimen for this group of patients.

Ondansetron should not be prescribed during pregnancy. Unknown, penetrates ondansetron in breast milk, so feeding breast during the period of treatment should stop.

The

Children

Children up to 4 years the drug in this dosage form is not used.

application Features

Ondansetron is not effective for the prevention of nausea and vomiting associated with motion sickness.

there is an experience of cross-hypersensitivity to various antagonists of 5NT3receptors therefore, in the presence of hypersensitivity to one of the antagonists of 5NT3receptors, a similar reaction to other antagonists may be more pronounced due to cross-reactions. In the presence of even a weak hypersensitivity reaction to one of the antagonist drugs

5NT3receptors it is not recommended to change it to another, given the possibility of increasing the hypersensitivity reaction.

Rarely during the use of ondansetron to meet transient ECG changes, including prolonged QT interval. The drug should be used with caution in the treatment of patients with cardiac arrhythmias or conduction, patients who are used in the treatment of antiarrhythmic drugs or ?-blockers, as well as in the treatment of patients with impaired electrolyte balance of high severity. According to postmarketing observations, there have been reports of cases of tremors/ventricular fibrillation in the application of ondansetron, so care should be taken in patients who have or may develop QT prolongation. This group includes patients with electrolyte imbalance disorders, with congenital Qt elongation syndrome, or who are treated with other drugs that can cause Qt interval elongation.

Ondansetron increases transit time through the colon, so in the presence of even weak signs of intestinal obstruction need constant supervision of the patient, if he uses the drug.

Ondansetron does not affect the cytochrome P450 system, but the use of other drugs that can affect the activity of these enzymes can lead to changes in clearance rates and half-life time of ondansetron.

in children who receive ondansetron together with hepatotoxic chemotherapy drugs, it is necessary to carefully monitor possible disorders of liver function.

since the tablets contain carbohydrates, including lactose, patients with impaired carbohydrate tolerance, with rare hereditary diseases, such as galactose intolerance, lactase deficiency or glucose-galactose malabsorption, it is impossible to take the drug.

The

Ability to influence the reaction rate when driving motor transport or operating other mechanisms

Taking into account the possibility of adverse reactions from the nervous system, patients during treatment are advised to refrain from driving or working with other mechanisms.

The

Interaction with other medicinal products and other forms of interaction

Ondansetron is metabolized by enzymatic system of cytochrome P450, thus, inducers or inhibitors of microsomal enzymes may change the clearance and half-life of the drug caution should be used with enzyme inducers (barbiturates, carbamazepine, carisoprodol, glutethimide, griseofulvin, nitrous oxide, papaverine, phenylbutazone, phenytoin, rifampin, tolbutamide), enzyme inhibitors (allopurinol, macrolide antibiotics, MAOIs, chloramphenicol, cimetidine, ?strogensoder?a?imi contraceptives , diltiazem, disulfiram, valproic acid, sodium valproate, erythromycin, fuconazole, fluoroquinolones, isoniazide, ketoconazole, lovastatin, metronidazole, omeprazole, propranolol, quinidine, quinine, verapamil).

the Ondansetron does not interact with alcohol, temazepam, furosemide, tramadol and propofol. Carmustin, etoposide, cisplatin IS not injected into the pharmacokinetics of ondansetrona.

Ondansetron may reduce the analgesic effect of tramadol.

the use of ondansetron with drugs that extend THE Qt interval may result in an additional prolongation of THE Qt interval. The simultaneous use of ondansetron with cardiac drugs (for example anthracyclines) can increase the risk of arrhythmias.

The

Pharmacological properties

Pharmacodynamics.

Ondansetron hydrochloride is an antagonist of the serotonin receptor subtype 5NT3. The mechanisms of antiemetic action are not fully established. It is known that the use of radiation and cytotoxic chemotherapy leads to the release of serotonin (5NT) with enterochromafinnyh cells of the small intestine. The initiation of the gag reflex is associated with the interaction of serotonin with 5NT3receptors located on the afferent extremities of the vagus nerve. Activation of the afferent limbs of the vagus nerve can cause the release of serotonin in the Central nervous system from the chemoreceptorial trigger zone located in the area of the bottom of the fourth ventricle of the brain. It is believed that ondansetron blocks the initiation of gag reflex at the level of both afferent limbs of the vagus nerve and serotonin receptors located in the Central parts of the nervous system.

Ondansetron has a sedative effect, but without changing prolactin in blood plasma, does not reduce psychomotor activity of the patient.

with regard to the mechanisms of antiemetic action of ondansetron in the postoperative period, this issue has not been sufficiently studied.

Pharmacokinetics.

the Bioavailability of ondansetron after administration is 60%. In the body, it is actively metabolized, metabolites are excreted with feces and urine. After taking the maximum concentration is achieved in an hour and a half. The connection with plasma proteins is about 73%. Most of the administered dose is metabolized in the liver.

half - life - 3-4 hours; elderly persons-up to 6-8 hours. Less than 10% of the active substance is excreted in the urine unchanged.

these studies of metabolism in vitro ondansetron testify that he is the substrate of enzymes of cytochrome P450human liver, including CYP1A2, CYP2D6, and

CYP3A4. Metabolism of ondansetron is carried out more often by the enzyme CYP3A4. Since the metabolism of ondansetron can be carried out by several enzymes of the cytochrome P450 system, in the absence of one of the enzymes, the total clearance of ondansetron does not change significantly, since the lack of one of the enzymes will be compensated by other enzymes of the metabolism system.
