Clinical Pharmacology

Pharmacotherapeutic group: combined bronchodilator (β2-adrenergic mime selective + m-anticholinergic)

ATX code: R03AK03

Pharmacological properties Ipraterol-aeronavat contains two components that have bronchodilator activity: ipratropium bromide - m-holinoblokator and fenoterol - β2-adrenomimetic. Bronchodilation with inhalation ipratropium bromide is mainly due to local rather than systemic anticholinergic effects. Pharmacodynamics

Ipratropium bromide is a quaternary ammonium derivative with anticholinergic (parasympatholytic) properties. Ipratropium bromide inhibits reflexes caused by the vagus nerve. Anticholinergics prevent an increase in the intracellular concentration of calcium ions, which occurs as a result of the interaction of acetylcholine with muscarinic receptors of smooth muscles of the bronchi. The release of calcium ions is mediated by a system of secondary mediators, including ITP (inositol triphosphate) and DAG (diacylglycerol). In patients with bronchospasm associated with chronic obstructive pulmonary disease (chronic bronchitis and pulmonary emphysema), a significant improvement in lung function (an increase in forced expiratory volume in 1 second (FEV1) and peak expiratory flow rate (PSV) by 15% or more) is observed during 15 minutes, the maximum effect is achieved in 1-2 hours and lasts for most patients up to 6 hours after administration. Ipratropium bromide does not adversely affect the secretion of mucus in the respiratory tract, mucociliary clearance and gas exchange. Fenoterol selectively stimulates β2-adrenoreceptors in a therapeutic dose. Stimulation of β1-adrenoreceptors occurs when using high doses. This explains the β-adrenergic (stimulating β-adrenergic receptors) effect of the drug on heart activity, such as increasing the frequency and strength of heart contractions, lengthening the QTc interval. Fenoterol relaxes the smooth muscles of the bronchi and blood vessels and counteracts the development of bronchospastic reactions caused by the effect of histamine, methacholine, cold air and allergens (immediate type hypersensitivity reactions). Immediately after administration, fenoterol blocks the release of inflammatory mediators and bronchial obstruction from mast cells. In addition, when using fenoterol in higher doses, there was an increase in mucociliary clearance. When using fenoterol using metered-dose aerosol inhalers (DAIs), systemic effects are noted when doses higher than recommended are used. However, after the use of fenoterol using nebulizers (solution for inhalation in vials with a standard dose), systemic exposure may be higher than when using the drug with DAI in the recommended doses. The clinical significance of these observations has not been established. The most commonly observed effect of β-adrenoreceptor agonists (β-adrenergic agonists) is tremor. In contrast to the effects on bronchial smooth muscles, tolerance to the systemic effects of β-adrenoreceptor agonists may develop, but the clinical significance of this manifestation has not been elucidated. With the combined use of ipratropium bromide and fenoterol bronchodilator (bronchodilator) effect is achieved by acting on various pharmacological targets. These substances complement each other; as a result, the antispasmodic effect on the muscles of the bronchi is enhanced and a greater breadth of therapeutic action is ensured in case of bronchopulmonary diseases accompanied by airway obstruction. The complementary effect is such that to achieve the desired effect, a lower dose of the β-adrenergic component is required, which allows an individual to choose an effective dose with virtually no side effects.Pharmacokinetics There is no evidence that the pharmacokinetics of the combined drug is different from that of each of the individual components. Absorption of Ipratropium bromide. After inhalation, usually 10-30% of the administered dose is administered to the lungs (depending on the dosage form and method of inhalation). Most of the dose is swallowed and enters the gastrointestinal tract. Part of the dose that passes into the lungs quickly reaches the systemic blood flow (within a few minutes). The overall systemic bioavailability of ipratropium bromide, used by inhalation, is 7-28%. Fenoterol. Depending on the method of inhalation and the inhalation system used, about 10-30% of the active substance reaches the lower respiratory tract and the rest is deposited in the upper respiratory tract and is swallowed. As a result, a certain amount of inhaled fenoterol enters the gastrointestinal tract. Suction is biphasic - 30% fenoterol is rapidly absorbed with a half-life (T1 / 2) of 11 minutes, and 70% is absorbed slowly from T1 / 2 - 120 minutes. There is no correlation between plasma concentrations of fenoterol, achieved after inhalation, and the time-effect pharmacodynamic curve. The prolonged (3-5 hours) bronchodilatory effect of the drug after inhalation, comparable to the corresponding effect achieved after intravenous administration, is not supported by high concentrations of the active substance in the systemic circulation. Distribution Ipratropium bromide. A rapid two-phase decrease in plasma concentration is observed.

The apparent volume of distribution during the state of equilibrium concentration (Css) is approximately 176 liters (≈ 2.4 l / kg). Ipratropium bromide binds to plasma proteins to a minimum (less than 20%). Ipratropium bromide, which is a quaternary amine, does not penetrate the blood-brain barrier. There is no data on the possibility of penetration of ipratropium bromide through the placental barrier and into breast milk. Not cumulated. Fenoterol. Fenoterol is intensively distributed throughout the organs and tissues. The apparent volume of distribution during the state of equilibrium concentration is approximately 189 liters (≈2.7 l / kg). Communication with plasma proteins 40-55%. Fenoterol in unchanged form penetrates the placental barrier and is excreted in breast milk. Metabolism Ipratropium bromide. Metabolized by oxidation, mainly in the liver. Up to 8 metabolites of ipratropium bromide are known, which are weakly associated with muscarinic receptors and are considered inactive. Fenoterol. Metabolized in the liver. When ingested, fenoterol undergoes biotransformation due to the effect of "primary passage" through the liver. The swallowed amount of the drug does not affect the concentration of the active substance in the blood plasma, achieved after inhalation. In humans, biotransformation of fenoterol occurs by conjugation with glucoronides and sulfates. After ingestion, fenoterol is metabolized primarily by sulphation in the intestinal wall. Removal of Ipratropium bromide. Excreted mainly through the intestines, as well as through the kidneys. About 25% is excreted unchanged, the rest is in the form of metabolites. Fenoterol. The main part of fenoterol undergoes biotransformation, including excretion with bile, approximately 85%. Urinary excretion of fenoterol (0.27 L / min) corresponds to approximately 15% of the average total clearance of the systemically available dose. The volume of renal clearance indicates tubular secretion of fenoterol in addition to glomerular filtration. After inhalation, the metered aerosol in an unchanged form is excreted through the kidneys of 2% of the dose within 24 hours. Pharmacokinetics in different groups.

The pharmacokinetics of the combination of ipratropium bromide and fenoterol in patients with diabetes mellitus has not been studied.

Contraindications

Hypersensitivity to fenoterol, ipratropium bromide (as well as to other atropine-like drugs) and auxiliary components that make up the drug. ? Hypertrophic obstructive cardiomyopathy. ? Tachyarrhythmia. ? First trimester of pregnancy. ? Children's age up to 6 years. Precautions Ipraterol-aeronaut should be used with caution in patients with such diseases as angle-closure glaucoma, chronic heart failure, coronary heart disease, arrhythmias, aortic stenosis, hypertension, inadequately controlled diabetes mellitus, recent myocardial infarction (during the last 3 months) severe organic diseases of the heart and blood vessels, hyperthyroidism, pheochromocytoma, prostatic hyperplasia, bladder neck obstruction, cystic fibrosis.

The drug Ipraterol-aeronaut should be used with caution in children and adolescents aged 6 to 18 years.

Drug interactions

Simultaneous use of other β-adrenomimetic agents, anticholinergic drugs, including systemic action, and xanthine derivatives (for example, theophylline) can enhance the bronchodilator effect of the drug Ipraterol-aeronavat and lead to the aggravation of side effects. Perhaps a significant weakening of the bronchodilator action of the drug, while the appointment of β-blockers. Hypokalemia associated with the use of β-adrenomimetics, can be enhanced by the simultaneous appointment of xanthine derivatives, glucocorticosteroids and diuretics. This fact should be given special attention when treating patients with severe obstructive respiratory diseases. Hypokalemia can lead to an increased risk of arrhythmias in patients receiving digoxin. In addition, hypoxia can increase the negative impact of hypokalemia on the heart rhythm. In such cases, it is recommended to monitor the level of potassium in the blood serum. It is necessary to carefully prescribe β2-adrenergic agents to patients who received monoamine oxidase inhibitors, tricyclic antidepressants, L-dopa, L-thyroxin, oxytocin, as these drugs can enhance the effect of β-adrenergic drugs. Inhalation of general anesthetics, such as halogenated hydrocarbon anesthetics (halothane, trichlorethylene, enflurane), may increase the adverse effect of β-adrenergic drugs on the cardiovascular system.

Pregnancy and Lactation

Existing clinical experience has shown that fenoterol and ipratropium bromide do not have a negative effect on pregnancy. However, when using these drugs during pregnancy (second and third trimester), normal precautions should be observed. It is necessary to take into account the inhibitory effect of the drug Ipraterol-aeronaut on uterine contractility. Fenoterol passes into breast milk. With regard to ipratropium bromide, such data are not obtained. The safety of the drug during lactation has not been established. In this regard, the use of the drug Ipraterol-aeronaut during lactation is possible only in cases where the potential benefit to the mother outweighs the potential risk to the child.

Special instructions

In the case of an unexpected rapid increase in shortness of breath (difficulty breathing), you should immediately consult a doctor. In children, the drug should be used only on prescription and under the supervision of adults.

Use in children under 6 years of age is contraindicated due to lack of experience with the application. Hypersensitivity: Immediately after the use of the drug Ipraterol, an immediate hypersensitivity reaction may occur, signs in which in rare cases can be: urticaria, angioedema, rash, bronchospasm, oropharynx edema, anaphylactic shock. Paradoxical bronchospasm: Ipraterol-aeronaut, like other inhalation drugs, can cause paradoxical bronchospasm, which can be life-threatening. In the case of the development of paradoxical bronchospasm, the use of the drug Ipraterol-aeronaut should be immediately stopped and switched to alternative therapy.

Prolonged use: - In patients suffering from bronchial asthma, Ipraterol-aeronaut should be used only as needed.

In patients with a mild form of chronic obstructive pulmonary disease, symptomatic treatment may be preferable to regular use; - in patients with bronchial asthma should be aware of the need for or enhance anti-inflammatory therapy to control the inflammatory process of the respiratory tract and the course of the disease. Regular use of increasing doses of drugs containing β2-adrenomimetics, such as the drug Ipraterol-aeronaut, to relieve bronchial obstruction can cause an uncontrolled worsening of the course of the disease. In the case of increased bronchial obstruction, an increase in the dose of β2-adrenomimetics, including the drug Ipraterol-aeronativ, more than recommended for a long time is not only not justified, but also dangerous.To prevent a life-threatening deterioration in the course of the disease, consideration should be given to revising the patient's treatment plan and adequate anti-inflammatory therapy with inhaled glucocorticosteroids. Other sympathomimetic bronchodilators should be prescribed simultaneously with the drug Ipraterol-aeronaut only under medical supervision. Disorders of the gastrointestinal tract: In patients with a history of cystic fibrosis, violations of motility of the gastrointestinal tract are possible.

Violations on the part of the organ of vision: Ipraterol-aeronaut should be used with caution in patients predisposed to angle-closure glaucoma. There are separate reports of complications from the organ of vision (for example, increased intraocular pressure, mydriasis, angle-closure glaucoma, pain in the eyes) that developed when inhaled ipratropium bromide (or ipratropium bromide in combination with β2-adrenomimetics) in the eye. Symptoms of acute angle-closure glaucoma can be pain or discomfort in the eyes, blurred vision, the appearance of a halo around objects and colored spots before the eyes, combined with corneal edema and reddening of the eye, due to conjunctival hyperemia. If any combination of these symptoms develops, the use of eye drops, reducing intraocular pressure, and an immediate consultation with a specialist are indicated. Patients should be instructed on the correct use of the inhalation drug Ipraterol-aeronaut. Particular care should be taken to protect the eyes of patients prone to the development of glaucoma. Systemic effects: In diseases such as recent myocardial infarction (during the last 3 months), inadequately controlled diabetes mellitus, serious organic diseases of the heart and blood vessels, hyperthyroidism, pheochromocytoma, or urinary obstruction (for example, prostatic hyperplasia or cervical obstruction) bladder) Ipraterol-aeronaut should be applied only after a thorough assessment of the risk / benefit. Effect on the cardiovascular system: In postmarketing studies, there have been rare cases of myocardial ischemia when taking β2-adrenomimetics. Patients with concomitant serious heart disease (for example, ischemic heart disease, arrhythmias, or severe heart failure) who are receiving Ipraterol-Aeronaut should be warned about the need to see a doctor if they develop heart pain or other symptoms that indicate worsening heart disease. It is necessary to pay attention to symptoms such as shortness of breath and chest pain, as they can be of both heart and lung etiology.

Hypokalemia: When using β2-adrenomimetics, hypokalemia may occur (see the “Overdose” section). In athletes, the use of the drug Ipraterol-aeronaut due to the presence of fenoterol in its composition can lead to positive results of tests for doping. Impact on the ability to drive a car and other vehicles, to work with moving mechanisms There have been no studies on the effect of the drug on the ability to drive vehicles and control mechanisms. In the event of such adverse reactions as dizziness, tremor, disturbance of accommodation, mydriasis and blurred vision, one should refrain from driving vehicles and controlling mechanisms, as well as from engaging in other potentially hazardous activities that require increased concentration and psychomotor reactions.

Overdosage

Symptoms Overdose symptoms are associated primarily with the effect of fenoterol. Symptoms may appear due to excessive stimulation of β-adrenoreceptors.The most likely occurrence of tachycardia, palpitations, tremors, hypertension or hypotension, increasing the difference between systolic and diastolic blood pressure, angina, arrhythmias and feelings of blood flow to the face, hyperglycemia, metabolic acidosis, hypokalemia. The possible symptoms of ipratropium bromide overdose (such as dry mouth, disturbed accommodation), given the greater breadth of the therapeutic effect of the drug and the local route of administration, are usually mild and transient. Treatment It is necessary to stop taking the drug. Blood pressure monitoring data should be taken into account. Showing sedatives, tranquilizers, in severe cases - intensive therapy. As a specific antidote, it is possible to use β-blockers, preferably β1-selective blockers. However, you should be aware of the possible increase in bronchial obstruction under the influence of β-blockers and carefully select the dose for patients suffering from bronchial asthma or chronic obstructive pulmonary disease, due to the risk of severe bronchospasm, which can be fatal.
