Interferon inductors, preparations for children: list, action. High-speed inducers of endogenous interferon
For the prevention and treatment of viral diseases, inducers of interferon are used. The mechanism of their action is associated with the production of protein substances that prevent the multiplication of pathogenic pathogens. Preparations based on inducers can fight against respiratory diseases, herpetic and hepatitis infections, influenza.
Definition of interferon
This is the name of a group of compounds having a protein origin. They are produced by cells that are infected with viral pathogens.
Interferon substances belong to the factors of the nonspecific protective mechanism in the body against bacterial, chlamydial, pathogenic fungal infections, cellular structures of tumors. They also play the role of regulators of intercellular interaction of systemic immunity. They are also called immunomodulators with endogenous nature.
There are several forms of human interferon substances: leukocyte, or a-interferon, fibroblast, or b-interferon, and immune, or g-interferon.
The scheme of the mechanism of their work begins with the binding of proteins and receptors of a specific nature in cells. With this interaction, protein molecules are synthesized within three dozen. With the help of regulatory peptides, stimulation of T-lymphocyte activity and macrophage structures is carried out, viruses are prevented from penetrating the cell membrane and multiplying them. They are responsible for the protective properties.
Natural interferon inducers are viral cells that have penetrated into the living organism. They are strong and weak stimulants for producing protective protein. Most pathogens of severe illnesses are poor inducers. These include cytomegalovirus and HIV infection, herpes, hepatitis forms C and B. But many pathogens that cause respiratory viral diseases are considered to be strong stimulants for the production of protective proteins.
Inductors of interferon( drugs): what is it?
Usually this is the name of medicines of the class of synthetic immunomodulators. They are produced by pharmaceutical companies. Interferon inductors( drugs) are considered to be a large class of compounds with different chemical structures. The active ingredient can be a low- and high-molecular substance, of synthetic or natural origin. They share a common property that allows one to induce in the cells of the body an own or endogenous interferon. Such drugs are capable of exhibiting antiviral and immunomodulating effects.
How do
Inductors of endogenous interferon - drugs directed in most cases to combat a viral infection. The mechanism of their action is based on the contact of the active substance of the drug with the cellular and tissue contents, the result of which is the development of a protective protein.
Interferon inductors are pharmaceutical preparations that enhance the secretion of protein artificially. Their action is similar to natural stimulants, which include viral, bacterial cells and various substances.
The use of interferon inducers can provoke hyporeactivity. In this state, when the drug is not administered again, the protective protein does not respond, and its suppression is observed. At this stage, it is inappropriate to administer the drug. The duration of such a state is determined by the inductor itself. The change in the active substance, as well as the interruption of treatment with the same agent, contribute to the elimination of hyporeactivity.
The administration of drugs that stimulate the production of protective protein does not cause serious undesirable consequences requiring their cancellation.
Advantage of inducers of endogenous protein
There are two ways to enhance immunity with interferon. This compound can be administered exogenously or directly into the body. Another way implies endogenous interferonization with the introduction of substances that stimulate the production of its own interferon. Such a protein does not show antigenicity, which can not be said for a recombinant interferon. Prolonged introduction of ready-made protein in the form of preparations leads to the development of undesirable reactions.
Inductors of endogenous interferon in the study of their effectiveness showed pharmacological activity in a wide range of infections. Their bi-functional property, characterized by antiviral effect and pronounced immunomodulatory effect, was established.
The action of inducers of interferon leads to the synthesis of proteins, which in their activity are similar to ready-made protective proteins. Such a process is considered balanced, it is controlled by mechanisms that reliably protect the body from excessive formation of these compounds.
With a single use of drugs that induce interferon, a fairly long circulation of protective protein takes place at the desired therapeutic dose. To obtain such a dosage in the appointment of an exogenous protein, it should be repeatedly administered in large volumes. Such treatment is considered more expensive.
List of drugs
Currently, doctors are increasingly using interferon inductors - drugs, a list of which every year is replenished with new medicines. A large number of immunomodulating drugs can fight many diseases.
As part of the immune system, there are functionally interconnected components that eliminate the antigenic compounds that are unusual for the body. Each element of immunity has specific agents. This explains the variety of drugs that contribute to the development of a protective protein.
There are various inducers of interferon( drugs), the list of which is headed by the drug "Poludan".This drug is considered to be the very first stimulant of protective proteins, which began to be used in the 70s. It includes polyadenyl and polyuridic acids. Its effectiveness in the production of interferon is low. Kapljami by eye and injections of a preparation "Poludan" treat herpetic keratitis and keratoconjunctivitis. Drug solutions are made for the therapy of colpitis and herpetic vulvovaginitis.
Interferon inducers - preparations "Aktaviron", "Lavomax", "Tilaxin", "Tiloron dihydrochloride", "Amiksin", "Tiloram" - have an active component of Tylorone in their composition.
Medicines "Ridostin" and "Sodium salt of double-stranded ribonucleic acid" are released with the active substance of sodium ribonucleate.
The substance of umifenovir is a part of the medicines Arbidol, Arbivir, Immustat and Arpefly.
There are also inducers of interferon, the preparations of which are called by the name of active substances. These include tablets "Kagotsel" and "Tyloron."
Based on meglyumin acridone acetate, medicines "Meglumine acridonacetate" and "Cycloferon" are produced, and sodium oxodihydroacridinylacetate is present in the drug "Neovir".
The composition of the drug "Yodantipirin" includes 1-phenyl-2,3-dimethyl-4-iodopyrazolone, and in the tablets "Alpizarin" contains the salt of the magnetrin.
Interferon inductors for children, their description
There is a large number of adult medications that can be given to a child, but only at a certain age. For example, with the drug "Tsikloferon" begin to treat four-year-old children, and the remedy "Ridostin" is appointed from the age of seven. Both drugs have a wide range of effects. They are suitable for the treatment of respiratory diseases of the viral nature, the state of influenza, hepatitis chronic, herpes. Their disadvantage is the possible unwanted side reactions.
Interferon inductors are preparations for children in a special form designed specifically for the child. Among them, the means Arbidol. It has been used since the age of two. The pediatric form of the medication is made in the form of capsules for internal administration. The drug has antiviral and immunomodulating action.
It refers to anti-influenza drugs that inhibit viral cells B and A type. With his participation, the development of internal interferon, which prevents contact and penetration of the infection inside the cell, is stimulated. Under the action of the protective protein, the lipid viral envelope is incapable of connecting to the cell membrane.
Inductors interferon for children contribute to the enhancement of immunity of humoral type, when they act, the body becomes more resistant to infectious agents, reducing the number of complications.
The drug "Kagocel" has a similar effect on the child's body. It is manufactured in the form of tablets for internal use. The permissible age of use of the drug is from three years.
Therapy of respiratory diseases
Interferon inductors are preparations for the treatment of acute respiratory viral infections, which lead to the formation of a protective protein in the cells of the body. They are also prescribed for influenza illness.
The most effective drugs are drugs based on Tyloron, which include tablets "Tiloron" and "Amiksin."For the treatment of influenza and acute illness of respiratory viral nature, adults are recommended to use 125 mg at a time. This dose extends to the first two days, then 125 mg taken every other day. The course amount of the drug is 750 mg.
To conduct preventive measures, 125 mg is used at one time, then a 6-day break. This course is repeated about six weeks.
Preparations based on Tylorone are contraindicated in the presence of individual intolerance, during pregnancy and breastfeeding of a child.
Taking such medicines can cause nausea, high body temperature, an allergic reaction.
The drug "Umifenovir" has interferon-inducing activity, stimulation of cell-type immunity, increasing the resistance of the whole organism to infectious agents.
For prophylactic measures in contact with sick people, a daily dose of 200 mg is prescribed for one week. In the seasonal period of influenza and respiratory diseases, a daily dose of 100 mg is used at a time, then a two-day break is made. This course lasts three weeks. For the treatment of colds, 200 mg are prescribed 4 times a day for three days.
Drugs with Umifenovir are not used in the presence of individual intolerance, during severe somatic pathologies. Taking such medicines can cause allergic manifestations.
Treatment of autoimmune diseases
To such diseases include pathological conditions in which antibodies are produced or autoaggressive clones of killer cells multiply in response to healthy tissues. This leads to damage and destruction of healthy tissue, resulting in autoimmune inflammation.
Usually, interferon inducers are used for treatment. Preparations for autoimmune diseases are prescribed by those that have an immunosuppressive effect.
For the treatment of multiple sclerosis, the drug "Amiksin" is used. At the slightest manifestation of an acute respiratory infection that aggravates the condition, a dose of 125 mg or 250 mg of the drug after ingestion is prescribed. Tablets are drunk every other day, the duration of the intake is from 6 to 12 days.
To prevent the exacerbation of multiple sclerosis, 125 mg of the drug is prescribed, 2 times per 7 days.
In complex treatment of the active phase of the disease with the signs of exacerbation, the drug is taken 125 mg 10 times per 30 days for 6 months. The drug "Amiksin" is prescribed together with peptide bioregulators, the general effect of which reduces the sensitivity of the organism to the myelin protein.
Complex therapy with the drug "Cycloferon" allows you to fight arthritis with reactive and rheumatoid, systemic diseases that affect the connective tissue. His work is aimed at suppressing autoimmune processes, which provides an anti-inflammatory and analgesic effect. With the help of the device, the immune state is regulated with different immunodeficient abnormalities. The drug "Cycloferon" is produced in tablet form, in the form of injectable solution and liniment.
For the treatment of arthritis, the drug is administered intravenously or intramuscularly once a day. Dosage of 250 mg is used from the first to the twelfth day on even days. In acute diseases, an initial increased dose of 500 mg is used.
Therapy of viral diseases
The drug "Amiksin" refers to interferon inductors of the fluorescent low molecular weight class. With his participation, all kinds of protective proteins are formed, the level of which reaches the highest value in plasma after a day after the application of the drug.
The drug has a large range of antiviral effects. In addition to respiratory diseases, it is used for C and B hepatitis acute and chronic forms, herpes genital recurrence, infection of cytomegalovirus and chlamydia type.
Many antiviral drugs - inducers of interferon, not an exception is a means of "neovir".With his participation, a large amount of protective protein is produced, especially fibroblast type, which explains the immunomodulatory, antitumor and antiviral effects of this medication. The drug "Neovir" treats encephalitis, hepatitis C and B, urethritis, cervicitis, salpingitis caused by chlamydia.
Another similar inducer of a low molecular weight protective protein is the drug "Cycloferon", for the synthesis of which carboxymethylene acrydon is used methylglucamine salt. With his participation, alpha-interferon is formed, the content of which in the lymphoid tissue persists for three days.
In T and B lymphocytes, macrophages form a protective protein, activate the stem structures in the bone marrow, stimulate the production of granulocyte units. The drug is used for tick-borne encephalitis, herpes, hepatitis, cytomegalovirus, human immunodeficiency virus and papillomas.
In addition to antiviral effects, the drug is active in acute and chronic bacterial chlamydia, erysipelas, bronchitis, postoperative complications, infections of the genitourinary and ulcerative lesions.
In the pharmaceutical market, the drug "Lavomax" appeared, manufactured by Nizhpharm. It has an immunomodulatory effect, the ability to induce interferons, an antiviral effect of a large range.
The tablet "Lavomax" contains 125 mg of tylorone as an active compound. The drug is an analogue of the medicine "Amiksin".Its activity is aimed at stimulating the production of three types of interferon in T-lymphocytes, hepatocytes, cells of the epithelial intestinal wall.
The effect of immunomodulatory effects is due to the restoration of a balance between immunocompetent cells and the normalization of antibody production. The mechanism of antiviral activity is based on the inhibition of the synthesis of proteins specific for viruses in infected parts of the body. This violates their further reproduction.
The drug successfully treat influenza, respiratory diseases, viral hepatitis and herpes rashes.
Fast acting inductors
Usually, the introduction of such medications leads to the rapid development of a protective protein.
Fast-acting inducers of endogenous interferon for several hours in the body can cause protein formation, which proves their effectiveness.
The substance of Tyloron after internal application increases the protein concentration to its maximum value after 4 hours. There is a phased formation of interferon first in the intestine, then in the liver, and in a day - in the blood.
The drug "Cycloferon" induces a protein after 4 hours, and the peak is observed after 8 hours, after which the concentration gradually decreases.
