Description

Pharmacological action of

Pharmacotherapeutic group: Anti-inflammatory anti-bronchoconstrictor agent – leukotriene receptor

ATX blocker:

R.03.DC03 Montelukast

different pharmacodynamics: Cysteenyl-4 cells, strong 4 LTE4 cells, strong 4-LTE4 cells mast cells and eosinophils. These important pro-asthmatic mediators bind to cysteinyl-leukotriene receptors (CysLT), which are present in the human airways and are responsible for the reaction of bronchospasm, sputum production, vascular permeability and an increase in the number of eosinophils.

Montelukast is an orally active compound that has great affinity and selectivity for CysLT1 receptors. Montelukast in a dose of less than 5 mg relieves bronchospasm, inhalation induced LTD4. The bronchodilating effect is observed within 2 hours after oral administration. The bronchodilating effect of beta2-adrenergic agonists is enhanced when taking montelukast. Montelukast inhibits both the early and late stages of bronchospasm caused by exposure to antigens. Montelukast reduces the number of eosinophils in the peripheral blood in adults and children, and also significantly reduces the number of eosinophils in the respiratory tract. In patients with hypersensitivity to acetylsalicylic acid receiving inhaled and / or oral glucocorticosteroids (GCS), the addition of montelukast to therapy provides better disease control.

Pharmacokinetics: Absorption

After oral administration, montelukast is rapidly and almost completely absorbed. In adult patients, after taking chewable tablets at a dose of 5 mg on an empty stomach, the maximum plasma concentration (Cmax) is reached after 2 hours. The average bioavailability is 73%, this value decreases to 63% when taking Montelukast with food. After taking chewable tablets at a dose of 4 mg on an empty stomach in patients aged 2 to 5 years, Cmax is achieved after 2 hours. The average Cmax value in this group of patients is 66% higher, and the average Cmax value is lower than that in adults when taking film-coated tablets at a dose of 10 mg.

Distribution of

The binding of montelukast to plasma proteins is more than 99%. The distribution volume at equilibrium is on average 8-11 liters. Preclinical studies have revealed minimal penetration of montelukast across the blood-brain barrier. 24 hours after administration, the concentration of montelukast is minimal in other tissues.

Metabolism

Montelukast is extensively metabolized in the liver. When used in therapeutic doses, the concentration of montelukast metabolites in plasma in equilibrium in adults and children is not determined.

In vitro studies have shown that P450 cytochrome isoenzymes (3A4, 2A6 and 2C9) are involved in the montelukast metabolism, while montelukast does not inhibit cytochrome P450 isoenzymes at therapeutic concentrations: 3A4, 2C9, 1A2, 2A6, 2C19 and 2D6. Metabolites have a minor therapeutic effect of montelukast.

Excretion

The half-life of montelukast in young healthy adult volunteers is from 2.7 to 5.5 hours. Montelukast plasma clearance in healthy adult volunteers averages 45 ml / min. After oral administration of montelukast, 86% of the total amount is excreted through the intestines within 5 days and less than 0.2% through the kidneys, which, along with data on its bioavailability, confirms the excretion of montelukast and its metabolites mainly with bile.

Pharmacokinetics in special cases

The pharmacokinetics of montelukast in women and men is the same.

In elderly patients or patients with mild to moderate hepatic insufficiency, dosage adjustment of montelukast is not required.

The pharmacokinetics of montelukast in patients with renal failure have not been evaluated. Since montelukast and its metabolites are not excreted by the kidneys, dose adjustment in this category of patients is not required.

There is no data on the nature of the pharmacokinetics of montelukast in patients with severe hepatic impairment (more than 9 points on the Child-Pugh scale).

When taking high doses of montelukast (20 and 60 times the recommended dose for adults), a decrease in theophylline concentration in blood plasma is observed. When taking montelukast in recommended doses of 10 mg once a day, this effect is not observed.

Indications

Prevention and long-term treatment of bronchial asthma in children, including:

prevention of day and night symptoms of the disease (for children 2 years of age and older)

treatment of bronchial asthma in patients with hypersensitivity to acetylsalicylic acid (for children from 6 years or older)

warning of bronchospasm, caused by physical activity (for children from 2 years of age and older).

Relief of symptoms of seasonal and perennial allergic rhinitis in children from 2 years.

Contraindications

Hypersensitivity to the active or any auxiliary substance of the drug

children under 2 years of age (for a dosage of 4 mg) and up to 6 years of age (for a dosage of 5 mg)

patients with rare hereditary diseases: galactose intolerance, lactase deficiency or glucose-galactose malabsorption

phenylketonuria (contains aspartame).

Special instructions

The drug Almont is not recommended for the treatment of acute attacks of bronchial asthma. Patients with asthma are advised to always have emergency medications with them. When an acute attack occurs, short-acting inhaled betag-adrenomimetics should be used. Patients should consult their doctor as soon as possible, if they need more short-acting beta-adrenergic agonist inhalations than usual.

Do not abruptly replace Almonotherapy with inhaled or oral corticosteroids. There is no evidence proving the possibility of reducing the dose of oral corticosteroids while taking montelukast.

In rare cases, patients who receive anti-asthma drugs, including montelukast, may develop systemic eosinophilia, which is sometimes accompanied by clinical signs of vasculitis, the so-called Charge-Strauss syndrome, a condition that is eliminated by taking systemic corticosteroids. These cases are usually associated with dose reduction or discontinuation of oral corticosteroids therapy. It is impossible to exclude or establish the likelihood that antagonists of leukotriene receptors may be associated with the development of Charge-Strauss syndrome. Therefore, doctors need to be warned about the possibility of eosinophilia, a vascular rash, an increase in the severity of pulmonary symptoms, heart complications and / or neuropathy in patients. Patients who develop the above symptoms need to be re-examined and their treatment regimen reviewed. Treatment with Almont does not prevent the development of bronchospasm in patients with hypersensitivity to acetylsalicylic acid when using acetylsalicylic acid and other non-steroidal anti-inflammatory drugs.

Almont contains aspartame, a source of phenylalanine. This drug may be harmful to patients with phenylketonuria.

The drug contains lactose monohydrate and should not be taken by patients with rare hereditary diseases: galactose intolerance, lactase deficiency or glucose-galactose malabsorption.

Influence on the ability to drive vehicles and mechanisms

As a rule, montelukast does not affect the ability to drive vehicles or work with other mechanisms, but very rarely drowsiness and dizziness were noted in some patients, when these signs appear, patients are not recommended to drive vehicles and engage in other activities that require concentration and speed of psychomotor reactions.
