Imunorix solution for oral administration, 400 mg 7 ml 10 pcs


Detailed description of the study

In the human body, to combat pathogens of viral infections, there is a system of interferons, which is of great importance in regulating innate and acquired immunity.

Interferons are a family of proteins that are released by various cells in response to viruses and bacteria. Currently, there are three types of interferons. They are classified according to their structure, interaction with specific receptors and physicochemical properties.

Type I interferons are important for protecting the body from pathogens. They have a variety of effects on the innate and acquired functions of immune cells when infected by viruses, bacteria, parasites and fungi.

Type I includes the following interferons: α, β, ω.

The first two are similar in their functions and form class I, and gamma interferons belong to type II.

Interferon alpha (cellular) is formed by blood cells - leukocytes - and actively responds to the penetration of infectious agents (viruses, bacteria) into the human body.

Interferon beta is synthesized by connective tissue cells - fibroblasts - and is also actively involved in the fight against infectious agents.

A representative of type II interferons is interferon-γ.

Interferon gamma is produced by T lymphocytes, providing immunomodulatory and antitumor effects. The antiviral activity of interferons is based on the regulation of innate and acquired immune mechanisms. As a result of the protective effect of interferons, the binding of the virus to cells and the penetration of viral particles into cells stops.

Imunorix is ​​an immunostimulating drug whose active ingredient is pidotimod. This drug stimulates and regulates the cellular immunity of the human body due to its ability to activate the maturation of T-lymphocytes (blood cells). Imunorix also has a positive effect on macrophages, which capture antigen - a foreign substance. The drug is approved for use by children over 3 years of age and adults.

Pidotimod is used in the complex treatment of infections of the upper and lower respiratory tract - rhinitis, laryngitis, pharyngitis, as well as in the treatment of infections of the urinary system - cystitis, urethritis, pyelonephritis.

This study is conducted to evaluate the effectiveness of treatment with Imunorix and is based on determining interferon status (activity of alpha, beta and gamma interferons).

Assessing the body’s ability to produce these interferons against the background of complex treatment with Imunorix is ​​necessary to select antiviral therapy taking into account the individual characteristics of the human body.

Use during pregnancy and breastfeeding

There is no or limited experience with the use of pidotimod during pregnancy (less than 300 pregnancy outcomes). Experimental studies in animals did not reveal any direct or indirect adverse effects on reproductive function.

The use of Imunorix should be avoided during the first trimester of pregnancy.

There is no data on the excretion of pidotimod or its metabolites in breast milk. Breastfeeding should be stopped during treatment with the drug to avoid exposure of the child to the active substance.

pharmachologic effect

Immunostimulating drug.

Pidotimod stimulates and regulates cellular immunity. Induces the maturation and formation of immunocompetent T-lymphocytes in case of their deficiency, which assume the role of coordinators of specific immunity under physiological conditions due to partial replacement or enhancement of the functions of the thymus gland. In addition, pidotimod stimulates macrophages, whose main function is to capture antigen and present it on the cell membrane in combination with histocompatibility antigens. The body's ability to resist infectious agents is expressed in effective specific immune, cellular and antigen-antibody protective responses.

Pidotimod exerts therapeutic effects through immunostimulating effects on innate immunity and antibody production, cellular immunity and cytokine production. Pidotimod increases the production of superoxide anions, tumor necrosis factor alpha, NO (bactericidal effect), as well as chemotaxis and, accordingly, phagocytosis. The drug also increases the cytotoxic activity of natural killer cells.

Pidotimod enhances the functional activity of T and B lymphocytes, increases stimulation of the antigen-antibody reaction and prevents the development of apoptosis induced by dexamethasone, 12-O-tetradecanoylphorbol-13-acetate and calcium ionophore A-23I87.

Pidotimod increases interleukin-2 (IL-2) levels in aged rats and IL-2 gene expression in the spleen of rats. In particular, pidotimod has been shown to have an immunostimulating effect in cases of immune system deficiency, as well as when it functions at a physiological level.

Imunorix

Imunorix (pidotimod) is a synthetic immunomodulator. Used for the prevention and treatment of infections of the respiratory and urogenital tract (as part of adjuvant therapy in combination with antibiotics). It has a high degree of purification, which ensures its safety and good tolerance by patients. After oral administration, it is quickly absorbed from the digestive tract: the maximum concentration of the active substance is observed one and a half hours after administration. The half-life is 4 hours. It has an immunostimulating effect due to the activation of phagocytosis, natural killer cells, neoplastic cells and stimulation of the production of immunoglobulin A, which is not synthesized in the blood. The presence of food contents in the gastrointestinal tract affects the absorption of the drug, so it is recommended to take it on an empty stomach. Imunorix is ​​well tolerated and has a favorable safety profile. In clinical studies, rare side effects (epigastric pain, stomach discomfort) were reported, the incidence of which was comparable to the placebo groups. Imunorix does not enter into clinically significant interactions with other drugs. The effectiveness of the drug has been confirmed in a number of clinical studies in patients with various diseases. One study assessed the effectiveness of Imunorix in patients with chronic bronchitis and COPD. Study participants included in the control group took the drug for 60 days, after which they were monitored for three months.

It was found that Imunorix shortens the duration and reduces the number of episodes of exacerbations of the disease, and also reduces the need for antibacterial drugs. In children with treatment-resistant upper respiratory tract infections, Imunorix reduces the duration and severity of these infections. To confirm the effectiveness and safety of the drug, about 60 controlled, randomized, multicenter, blind clinical studies were conducted. Compared with placebo, a significant reduction in the duration of the disease was demonstrated by 33%, the incidence of infections of the lower respiratory tract by 2.5 times, the upper - by 3.5 times, the need for antibacterial and antipyretic drugs by 40%, the duration of the febrile period by 30 %, the number of episodes of recurrence of the disease by 2.5 times, the absence of cases of pharmacological interaction and the stability of the achieved result for three months after the end of the drug course. Imunorix is ​​effective both during exacerbation of the disease and during long-term drug therapy for recurrent respiratory tract infections. In pediatric practice, the drug can be used starting from the age of three.

Pharmacokinetics in special groups of patients

Pharmacokinetic studies in elderly patients did not reveal differences from pharmacokinetics in young patients.

T 1/2 increases with renal failure. However, in case of severe renal failure (plasma creatinine 5 mg/dL), T1/2 of pidotimod does not exceed 8-9 hours. patients take the drug every 12 hours or 24 hours, there is no risk of accumulation in renal failure.

Studies have not been conducted in liver failure, because the drug is almost completely excreted unchanged from the body in the urine.

Release form
