Why are expectorants prescribed for bronchitis? Because with inflammation of the bronchi appears cough - the main symptom of this disease, indicating the activation of the mucociliary system, which cleans the respiratory tract from pathogenic agents.

The protective system of the respiratory system works by the production of goblet cells of the mucous membrane and submucosal glands of mucin gel - a viscous adhesive mucus secretion containing glycoproteins, carbohydrates, sulfates, immunoglobulins. When inflammation increases the synthesis of thick mucus - to neutralize viruses or bacteria that hit the shells of respiratory organs. Thanks to a protective reflex, that is, a cough, mucus should be excreted from the bronchi, and help in this expectorant for bronchitis.

Release form

The form of release of these drugs is different: tablets, capsules, dragees, potions (solutions for oral administration), syrups, drops, as well as collections of medicinal plants.

Names of expectorants

The pharmaceutical market of ejectors - expectorants - offers many  

Mukoactive drugs that are divided into mucolytics (liquefying mucus) and mukokinetics (facilitating its excretion upon coughing) according to the mechanism of action. It should be noted that all expectorants initially will cause some increase in cough, but their main goal is to facilitate the elimination of excess mucus from the respiratory system.

According to doctors, to choose the best expectorant for bronchitis is difficult, because for drug treatment each organism reacts differently. And those who prefer herbal preparations, it should be remembered that such drugs can also give side effects.

Here are some names of expectorants, grouped according to the form of release (in parentheses are other trade names of drugs produced by different manufacturers, but identical in composition and all characteristics).

Expectorant tablets with bronchitis: Bromhexine (Bromhexin chloride, Brombenzonium, Brodizol, Bisolvon, Mukovin, Mugocil, etc.); Ambroxol (Ambrohexal, Ambrosan, Ambrobene, Bronhopron, Lazolvan, Medox, Mukozan); Acetylcysteine (Acestin, Acestad, Mukomist, Mistabren, Fluimutsil); Mukaltin.

Expectorants in capsular form: Carbocysteine (Mukodin, Mukoprint).

Granulated products (for the preparation of a solution taken orally) and in the form of effervescent water-soluble tablets: ACTS (Acestad), Bronhokod, Mucosol, Fluviert, etc.

Expectorants for bronchitis: Potassium iodide, Pertussin, Thoracic elixir, Ambroxol, Ascoril, Herbion, etc.

Expectorant syrups with bronchitis: Althea, Ambrohexal (Bronhoval, Lazolvan, Remebroks), Fljuditik (Bronkatar, Mukosol), Ascoril, etc.

Expectorants in the form of drops: ammonia-anise drops, Bronchosan (Bromhexin, Bronchotil, Flegamin), Gedelix (Hederin, Prospan).

Expectorant for chronic bronchitis, as well as expectorants for obstructive bronchitis (that is, when the bronchial mucous membranes swell and block their lumens) include virtually all of the listed products, as well as combined preparations with guaifenesin, such as Ascoril syrups or Sudafed.

Expectorant charges for bronchitis - pharmacies Thoracic collections - consist of medicinal plants. For example, Breast Collection No. 1 includes the leaves of the mother-and-stepmother and the oregano (Matinka), and in the Breast Collection No. 2 - the leaves of the mother-and-stepmother, plantain, and the licorice root of naked (liquorice).

If the collections are produced in filter bags (that is, vegetable raw materials are ground to a fine state), then one can make expectorant teas in bronchitis right in the cup.

A proven therapeutic effect is provided by expectorating herbs in bronchitis: mother-and-stepmother, oregano, marshmallow, licorice, thermopsis lanceolinate, plantain, thyme, sweet clover, blue sinew, angelica, spring primrose (primula forest), violet trichrome, mullein large .

The main folk expectorants for bronchitis are the listed medicinal plants from which they prepare decoctions or infusions (often with the addition of honey). Good tea helps with fennel seeds and ginger, a decoction of pine buds, black radish juice with honey, etc. More information in the material -  Obstructive bronchitis: treatment with alternative means

Pharmacodynamics

Expectorant tablets with bronchitis Bromhexine and Ambroxol belong to the group of mucolytic agents based on nitrogen-containing derivatives of benzylamine (1-phenylmethylamine), moreover, ambroxol is a metabolite of bromhexine, which has a similar pharmacological effect. Both substances increase the lysosomal activity of the enzymes of the goblet epitheliocytes of the bronchial mucosa, as a result of which hydrolysis of glycoproteins of the secretion of the secretion increases, and it, losing its viscosity, is easier to excrete when coughing.

Acetylcysteine (N-acetyl-L-cysteine) and all preparations containing it also act by diluting sputum due to the depolymerization of glycoprotein molecules. And the pharmacodynamics of carbocysteine (L-cysteine-S-carboxymethyl) is based on the inhibition of the activity of mucus-forming cells and the increase in the mucus content of water (which facilitates its coughing), as well as the stimulation of the villi of the epithelial tissue of the bronchi responsible for their purification.

Expectorant tablets with Muciltin bronchitis are a dry extract of the althea drug root and sodium bicarbonate. The root of the althaea contains potassium sorbate, glycosides, saponins, phytosteroids (β-sitosterol and lanosterol) and phenol carboxylic acids. In a complex, these compounds activate not only the secretory glands of the bronchial mucosa, but also the function of the ciliated epithelium.

Expectorants for bronchitis include a variety of drugs. Potassium iodide (1-3% solution) is used that promotes the cleavage of mucous proteins and mucopolysaccharides of thick sputum. Pertussin and the Thoracic Elixir are a combination of cough suppressants. Petrussin contains a liquid extract of thyme (thyme) and potassium bromide, and the active ingredients of the Thoracic elixir are the licorice root (extract), anise oil and ammonia in water (ammonia). Both medicines increase the production of mucous secretions and, at the same time, dilute it, and also reflexively activate the respiratory center.

Expectorant syrup Fluidite contains carbocysteine, the mechanism of action of which has been described above.

Pharmacologically active components of the Ascoril syrup are bromhexine, beta-adrenomimetic salbutamol and a semi-synthetic analogue of the glyceryl ester of guayaacol-guaifenesin. The cumulative effect of these substances is to stimulate bronchial beta-adrenoreceptors (which dilates the bronchi), reduce viscosity (by breaking down the sulfide bonds of high molecular weight polysaccharides) and increase the activity of the ciliated epithelium of the bronchi.

The expectorant effect of ammonia anise drops is provided by anise oil and ammonia solution, which reflexively stimulate respiration and enhance mucin secretion. And in the composition of Bronchosan drops - besides anise oil and bromhexine - essential oils of mint, oregano, fennel and eucalyptus are contained.

Drops Gedelix (Hederin, Prospan) is also of plant origin - based on the extract of ivy leaves, containing significant amounts of saponins.

Pharmacodynamics of phytopreparations, as a rule, is not presented in the instructions, since information on the mechanism of action of their active substances is not enough. So, we will limit ourselves to indicating the main active substances of medicinal plants capable of exerting an eksponentant effect.

In the root of licorice is glycyrrhizic acid (which removes inflammation and swelling not worse than glucocorticoids) and nearly three dozen different isoflavones. In the leaves of mother-and-stepmother, too, a sufficient set of flavone compounds, as well as glycosides, saponins and tannins. Among the compounds found in the essential oil of oregano and thyme - in addition to phenol carboxylic acids - there are anti-inflammatory anthocyanins and triterpene alcohols that promote liquefaction of thick sputum. Thanks to the steroid saponins and coumarins, the same effect is exerted by the plants blue and angelica (angelica).

Pharmacokinetics

In most cases, manufacturers of expectorant tablets, potions, syrups, etc. Do not give information on their pharmacodynamics. Exceptions - Acetylcysteine, Carbocysteine and guaifenesin (as part of Ascoril syrup or Bronchipret).

Bioavailability of acetylcysteine after taking drugs on its basis does not exceed 10%, and the connection with plasma proteins reaches 50%; the half-life period is about two hours. Biotransformation occurs in the liver with the formation of intermediate and final metabolites (sulfur compounds). Excretion is renal and intestinal.

Carbocysteine has a similar bioavailability, and the highest concentration in blood plasma is observed on average 2.5 hours after taking medications with its content. A small part of carbocysteine is transformed in the intestine, and the main amount is excreted unchanged - with urine.

Guaifenesin is characterized by good absorption in the esophagus and stomach with the ability to penetrate the bloodstream into all mucous membranes. This substance is metabolized in the liver, it is excreted from the body through the respiratory tract (along with phlegm) and kidneys (with urine).
