The impetus to the development of the disease is the destruction of the nerve shell in the spinal cord and brain, resulting in the formation of plaques of multiple sclerosis( foci).Their dimensions range from a few millimeters to several centimeters. During an exacerbation the formation of especially large plaques is peculiar.

The drug changes the course of the pathology, has a local immunomodulatory effect. The use of glatiramer acetate is also correct during remission, since in this case the agent reduces the incidence of exacerbations, and also inhibits the development of neurological disorders.

Indications for use

Indications for use of the drug is not so much. These include:

• Remitting multiple sclerosis. In this case, glatiramer acetate is used to reduce the frequency of exacerbations, as well as to slow down all the complications characteristic of the ailment.
• Clinically isolated syndrome, occurring with simultaneous pronounced inflammation, required intravenous glucocorticosteroids. In this case, the prescribed drug is used to slow the transition of the disease to the clearly identified multiple sclerosis.

1. Immune system: hypersensitivity, anaphylactic shock, angioedema.
2. Hematopoietic system: occurrence of such diseases as leukopenia, leukocytosis, lymphadenopathy, changes in lymphocyte structure, thrombocytopenia and splenomegaly. Endocrine system: hyperthyroidism.
3. Nervous system: headache, depression, anxiety, nervousness, euphoria, convulsions, impaired motor functions, stupor, etc.
4. From the side of metabolism: both weight gain and anorexia can be observed. In addition, hyperlipidemia, hypernatremia, gout are possible.

Trade name, manufacturer

Glatiramer acetate trade name has another. But more on that later. For a long time, until the contract with the Israeli company-supplier Teva was terminated, the facility was supplied to Biotech LLC.Glatiramer acetate is currently supplied by Teva itself through the Russian OOO Teva.

When prescribing the drug for multiple sclerosis, the doctor will most often indicate in the prescription the name: "Copaxon Teva".However, this is not the only agent whose main active ingredient is glatiramer acetate. Analogues are widespread, they include:

• "Copakson 40".
• "Glatirat".
• "Aksoglatiran FS".
• "Timekson".
