Pharmacological characteristics of astringents. Characteristics and classification of astringent medicinal substances. Enveloping and adsorbing agents

Astringents- these are agents that seal the surface layer of the mucous membranes and skin, forming a film that protects sensitive nerve endings from irritation. They produce:

Analgesic effect (reduction of pain in inflammatory processes)

Anti-inflammatory effect (narrowing of the vessel, decrease in their permeability, decrease in the manifestations of the exudative process);

Decreased secretion of the digestive glands.

Astringents include drugs of organic (vegetable) origin (tannin, oak bark, St. John's wort, blueberries) and inorganic (basic bismuth nitrate, denol, vikalik, vikair, xeroform, dermatol).

Tannin- halotannic acid, which is obtained from ink nuts, that is, growths on the shoots of Asia Minor oak and sumac. Assign for external use in the form of a solution and ointment for inflammatory processes of the skin and mucous membranes.

Oak bark contains 8% tannins, which determine its astringent effect. A decoction of oak bark is used to treat inflammation of the oral cavity, bleeding gums, and burns.

Sage drug. In medical practice, the leaves of the plant are used, which are stored in tightly closed containers. In the leaves of sage are volatile oils, alkaloids, tannins, flavonoids, exhibit astringent, anti-inflammatory, disinfectant action. It is used as an effective remedy for rinsing the mouth and throat with gingivitis, stomatitis, laryngitis, pharyngitis.

St. John's wort, blueberries, chamomile flowers, and the like also have an astringent effect. they are used in inflammatory processes of the mouth and throat, and are also taken orally for colitis, peptic ulcer of the stomach and duodenum.

Bismuth nitrate basic- astringent of inorganic origin. Assign for external use in the form of ointment and powder for inflammatory processes of the skin; inside - with peptic ulcer of the stomach and duodenum, enteritis, colitis. Combined preparations are also widely used - tablets Vikalin, Vikair, as well as bismuth subcitrate.

Denol(ventrisol) - astringent of inorganic origin. The drug has an astringent, antacid, cytoprotective effect, and also has an antibacterial effect in pylori. Applied with peptic ulcer of the stomach and duodenum, chronic gastroduodenitis. The drug is well tolerated, but nausea and vomiting are possible. Do not use in severe kidney disorders and during pregnancy.

Xeroform contains 50-55% bismuth oxide. Applied externally as an astringent and antiseptic in the form of powder, powder and ointment (3-10%) for skin diseases.

Obvolical means

Obvolical means- these are indifferent substances of plant origin that are capable of forming sticky liquids in water - mucus that covers the mucous membranes or skin with a protective film and protects them from irritation.

Assign obvolical means:

In inflammatory and ulcerative processes on the mucous membrane of the digestive tract;

In case of poisoning with acids, bases and the like;

To reduce the irritating effect of drugs. Obvolikalnu means include: starch, flax seeds, rhizomes and roots of marshmallow officinalis, as well as products - milk, egg white, decoctions of oatmeal.

Starch- adsorptive agent in the form of powders and obvolikalny - in the form of mucus.

Indications for use: prescribed for external use in the form of powder and paste for the treatment of dermatitis inside - in the form of mucus for the treatment of ulcers, inflammatory processes in the digestive canal; in case of poisoning with acids, alkalis and salts of heavy metals; in the form of a medicine - to reduce the irritating effect of certain drugs and slow their absorption.

Flax seeds produces an obvolical, laxative effect. Assign for external use in the form of mucus in acute inflammatory processes (abscess, furuncle, lymphadenitis, myositis, synovitis, bureitis, arthritis, etc.); inside - with gastritis, peptic ulcer of the stomach and duodenum.

Contraindications: active forms of tuberculosis; in the presence of a wound surface and in case of bleeding, one should not make poultices from flax seeds.

marshmallow root contains mucous and pectin substances, starch and the like. Assign in the form of infusion and medicine. Shows obvolicalno and anti-inflammatory action.

Indications for use: inside, 1 tablespoon of infusion or mixture every 2 hours or 4-6 times a day after meals for acute laryngitis, fariigiti, tracheitis, acute and chronic bronchitis, bronchopneumonia, catarrh of the upper respiratory tract, whooping cough.

Astringent action of medicinal plants is due to the physicochemical reaction that occurs when the binders contained in the plant come into contact with tissue fluids, intercellular substance and cells of the body. As a result, the cell membranes and the surface layer of the cellular protoplasm are compacted by an insoluble protein compound. The astringent action is characterized by reversible changes in the structure of proteins, the formation of sparingly soluble and low-permeability compounds.
With an overdose, a stronger manifestation of the astringent effect of the drug occurs, which leads to destructive changes in the entire cell or even tissues, which can cause increased local blood circulation, accelerated cell division and an increase in tissue fluid (irritant effect) or, finally, necrosis of superficial, and sometimes more deep layers of cells and the complete destruction of the latter (cauterizing effect).
Action of binders contained in medicinal plants, as a rule, is short-lived. Under the influence of astringents, a seal is formed on the surface of the cells, which protects the endings of sensory nerves from irritation, which leads to a weakening of the feeling of pain. When exposed to astringents, local vasoconstriction occurs, their permeability decreases and exudation processes decrease, and, consequently, the development of the inflammatory process slows down. Combining with the proteins of microorganisms, astringents reduce their vital activity, i.e. cause a bacteriostatic effect.

Astringents are divided into two large groups:

1) containing tannins, tannin.
2) Inorganic compounds (metal binders) which include salts of aluminum and many heavy metals, including lead acetate, bismuth nitrate, aluminum alum, zinc oxide, zinc and copper sulfates, silver nitrate.

organic binders

The most important member of this group is tannic acid, or tannin, from others you can specify: oak-tannic acid, catechudic acid, quinodubic acid, coffee-tannic acid and many others, which got their name from the plants in which they are contained.
All of them have a characteristic tart and astringent taste. When they come into contact with mucous membranes or wound surfaces, the latter shrink (due to protein coagulation, cells become more compact, smaller), turn pale (reduction of the lumen of small vessels due to contraction of their muscles or from compression by surrounding tissues) and become dry (cessation of secretion of glandular cells and exudation of fluid from the vessels). This is especially pronounced on inflamed tissues, due to which exudation decreases, the release of leukocytes is limited or even stops, and suppuration decreases. When astringents come into contact with blood, its proteins fall out, and. Local application of astringents as anti-inflammatory and hemostatic is based on these properties. In addition, when applied topically, they also show a weak antiseptic effect.

Use of organic astringents in medicine

Astringents of plant origin usually taken externally for catarrhal, purulent and ulcerative lesions of the skin and mucous membranes.
They are used for the purpose of local action in cases of excessive secretion (with ulcers, stomatitis, gingivitis, diarrhea, etc.), in case of metal and alkaloid poisoning, and as hemostatic.
Astringents of natural origin are often used in inflammatory processes in the intestines as anti-inflammatory, antidiarrheal and antimicrobial agents.
Astringent preparations taken orally cause a slowdown in peristaltic movements and a decrease in secretion, which leads to a thickening of the intestinal contents and its slower movement through the digestive tract. At the same time, reflex reactions are weakened and pain sensations are reduced.

Astringents are also used as deodorizing agents, since, by preventing rotting and changing rotten masses, they thus destroy the fetid odor.

Medicinal plants that have an astringent effect

Tannins have tanning properties and a characteristic astringent taste, they are found in the bark, wood, leaves, fruits (sometimes seeds, roots, tubers) of many plants - oak, chestnut, acacia, spruce, larch, Canadian hemlock, eucalyptus, tea, cocoa, pomegranate tree, persimmon and cinchona trees, sumac, quebracho and others; give leaves and fruits a tart taste. Tannins inhibit the growth of microorganisms pathogenic for many plants, protect plants from being eaten by animals.
However, not all astringent plants have an astringent taste.

According to their medicinal properties and use in medicine, astringent medicinal plants are divided into three groups:

Hemostatic to help stop bleeding. Typical hemostatic plants include hibiscus, oak, goldenseal (gold seal), mullein, nettle, turmeric, heart-leaved madder (manjishta), yarrow, blackhead, and saffron. Their taste is usually astringent or bitter, they improve metabolism, and purify the blood.

Fixing that stop the excessive excretion of waste products. Typical termination-promoting members of this group include gentian, blackberry, oak bark, red raspberry, water lily, lotus seed, sumac, and curly sorrel. To taste - astringent or bitter.
Plants with astringent action, stopping, blackhead, as well as honey are the most famous healing agents.
Healing herbs treat tissues damaged by cuts, wounds, burns, hemorrhages, etc. Usually they are used externally in the form of poultices and patches. Having a mostly astringent or sweet taste. However, they are not as effective for deep or extensive tissue damage. Many of them have a softening and soothing effect on the skin and mucous membranes. Some may contain vegetable slime.

Some herbs have three kinds of astringent at once, and because of this they have become known as herbs that heal all ailments. These include yarrow and blackhead.

Introduction

A significant section of private pharmacology is devoted to drugs that affect the nervous regulation of body functions. With the help of such substances, it is possible to influence the transmission of excitation at different levels of the central nervous system, as well as in the efferent and afferent pathways of peripheral innervation.

Based on the structural and functional features of different parts of the reflex arc, substances are isolated that affect the afferent and efferent innervation.

This is how drugs are isolated that reduce the sensitivity of the endings of afferent nerves or prevent their excitation. This group includes anesthetics, astringents, enveloping and adsorbing substances.

In this essay, binders will be considered.

1. Astringent medicines

Astringent drugs (from lat. adstringentia - viscous) include drugs that cause when applied to an inflamed area of ​​\u200b\u200bthe skin or mucous membrane. As well as the wound surface, effective dehydration (dehydration) and partial coagulation (coagulation) of proteins and, in addition, having a local anti-inflammatory and weak local anesthetic effect. As a result of dehydration and coagulation of proteins, a protein film is formed on the inflamed surface, which mechanically protects the underlying tissues and the endings of afferent nerve fibers from exposure to irritating substances. The resulting protein film covers the tissue (cells) with a thin layer and thereby protects the receptors from irritation, thickens and tightens the tissue, reduces the secretion of glands, and stops the release of inflammatory exudate from tissue crevices. Astringents narrow the lumen of small vessels and capillaries, agglutinate erythrocytes, as a result of which bleeding stops. They also have some antimicrobial activity based on the precipitation of microbial cell proteins. As a result, astringents have anti-inflammatory, hemostatic, bacteriostatic and deodorizing effects.

Astringents taken orally protect the nerve endings of the mucous membrane of the stomach and intestines from irritation, slow down peristalsis and secretion in the intestines; this helps to slow down the movement of the contents through the digestive tract.

In high concentrations, astringents, penetrating deep into the cell, cause coagulation (coagulation) of the protein, exerting a cauterizing effect. This entails suppression of glandular excretion, constriction of blood vessels, and a decrease in the feeling of pain. In addition, as a result of the dehydrating action of drugs of this group, the underlying protein layer, losing water, becomes denser, the permeability of cell membranes decreases, which ultimately results in a decrease in local inflammatory processes.

Usually, astringent drugs are classified depending on the sources of raw materials.

1. Astringent medicinal products of plant origin (organic astringent drugs): decoction of oak bark; tannin (tannin - gallotannic acid, obtained from growths of Asia Minor oak); tanalbin (tannin with casein); infusion of sage leaves; infusion or decoction of bird cherry fruits; infusion or decoction of blueberries; calamus rhizome, etc.

2. Astringent drugs of synthetic origin (inorganic astringent drugs): bismuth compounds (basic bismuth nitrate, bismuth gallate basic - dermatol, bismuth tribromophenol basic - xeroform, etc.); aluminum compounds (aluminum-potassium alum, burnt alum); zinc compounds (zinc sulfate, zinc oxide); copper sulfate; lead acetate.

Astringent medicinal products of plant origin are mainly used in gastroenterology, dermatology, dental and ENT practice.

In gastroenterology, infusions and decoctions of astringent herbal medicines are used for the symptomatic treatment of gastritis, enterocolitis and colitis. In diseases of the lower gastrointestinal tract, they are used in enemas. In some cases, the drug tanalbin is used to treat diarrhea.

For the treatment of peptic ulcer of the stomach and duodenum, combined drugs containing both organic and synthetic astringents are used. An example of them is the preparations vikair and vikalin, which, among other things, include basic bismuth nitrate and calamus rhizome powder.

Astringent drugs of inorganic origin are currently rarely used in clinical practice. However, basic bismuth nitrate has been shown to be used to treat gastric and duodenal ulcers.

In dermatology, these drugs are used for inflammatory skin diseases, superficial ulcers, light burns and other injuries by applying to the skin surface in the form of solutions, decoctions, ointments. For example, dermatol and xeroform preparations are used in dermatology in the form of powders and ointments for the treatment of inflammatory skin diseases. In addition, xeroform is a part of the balsamic liniment according to Vishnevsky.

In ENT practice, astringent herbal medicines are used for rinsing and inhalation in the treatment of stomatitis, laryngitis, tracheobronchitis, etc. Some of them, for example, a decoction of sage, in addition to the astringent, also have a certain antimicrobial activity.

An astringent of plant origin - tannin - has the ability to form insoluble compounds with salts of heavy metals and some alkaloids, so its 0.5% solution in a volume of 2 liters is used to wash the stomach through a tube in case of poisoning with atropine, cocaine, morphine, nicotine, physostigmine, salts copper. However, after washing the stomach with a solution of tannin, it is necessary to rinse it well with water, since the complexes that tannin forms with these compounds are unstable, and their release from the bond with tannin is possible.

Aluminum-potassium alum is used both in the form of aqueous solutions for rinsing, lotions, washes and douches in inflammatory diseases of the mucous membranes, and in the form of crystals to stop bleeding with small cuts, for example, when shaving.

Astringents, when applied to mucous membranes, cause coagulation of proteins; the resulting film protects the mucosa from irritating factors. The vasoconstriction and “tightening” of the mucosal surface leads to a decrease in pain sensations, a weakening of inflammatory processes.

Such an effect is exerted by many substances of plant origin (from St. John's wort, blueberries, oak, etc.), as well as weak solutions of salts of certain metals (silver, aluminum, zinc, etc.).

Astringents, when applied to mucous membranes, cause coagulation of proteins; the resulting film protects the mucosa from irritating factors. The vasoconstriction and “tightening” of the mucosal surface leads to a decrease in pain sensations, a weakening of inflammatory processes. Analgesic and analgesic drugs.
