Glivec: discover how chemotherapy treatment works

The Leukemia is a type of cancer which is expressed in blood cells (such as white blood cells, red and white blood cells).

Its main characteristic is the accumulation of cancer cells in the bone marrow that end up spreading and contaminating the blood cells.

There are 12 different types of leukemia, each with its own particularities.

The national Cancer Institute (INCA) estimates that in 2020, about 10,000 new cases will be diagnosed in the country.

Fortunately, these people will be able to count on the help of numerous medications, including Glivec.

What is Glivec used for?

Glivec is a remedy indicated to treat various diseases such as cancer of the blood cells, intestine and stomach. Find out exactly what types of tumors are treated:

Chronic myeloid leukemia

Chronic Myeloid Leukemia (CML) is a type of cancer in the blood, in which there is a large production of white cancer cells known as myeloid cells.

Glivec is used to treat pediatric cases (older than 2 years) and adults who have a positive Philadelphia chromosome (Ph +) CML who have been recently diagnosed and have not been treated yet.

Only in adults, it is also useful for those who are in an accelerated or chronic phase and have not responded to treatment with alpha interferon therapy.

Acute Lymphoblastic Leukemia

Acute Lymphoblastic Leukemia (ALL) is a type of cancer in the blood.

Its main feature is the high production of white cancer cells known as lymphoblasts.

This reference drug is indicated for the treatment of patients older than 1 year who have a positive Philadelphia chromosome ALL (Ph +) that was recently diagnosed, in combination with chemotherapy.

Gastrointestinal Stromal Tumors

Gastrointestinal stromal tumors are also called GIST.

They are tumors present in the intestine and stomach and arise from the uncontrolled growth of the cells that make up the supporting tissues of these same organs.

Glivec is used to treat adults with non-resectable or metastatic GIST (cancer of the stomach and intestine) (when the disease spreads to the rest of the body).

In addition, for the adjuvant treatment of adult patients after resection of primary GIST.

What is the mechanism of action of the active ingredient Imatinib mesylate?

The active ingredient in Glivec acts in the production of cancer cells, interrupting their development and preventing them from reproducing.

Imatinib Mesylate is considered a tyrosine kinase inhibitor, that is, it prevents the action of a protein known as tyrosine kinase BCR-ABL, which is the main cause of tumors in the blood.

Glivec is the first drug of its kind that was developed in Brazil. Today, although it is the reference, it is possible to find other brands that also manipulate the active ingredient Imatinib Mesylate.

Is Glivec chemotherapy?

Yes, Glivec is a drug considered as chemotherapy and has become one of the main drugs on the list to combat various types of blood cancer.

Therefore, the ideal is to follow the medical guidelines in relation to the dosage and the way to take this type of medication.

But what is chemotherapy? Let’s explain it better:

This treatment line uses drugs to fight sick cells that cause a tumor (cancer).

These drugs fall directly into the bloodstream and thus spread to the rest of the body and fight cancer cells (which cause the disease).

It can be administered through the mouth (oral), with injections into the veins (intravenous), into the muscles (intramuscular), below the skin (subcutaneous) and in ointments on the skin (topical).

In the case of Glivec, the administration is by tablets that must be taken orally (through the mouth).

Chemotherapy is famous because of its aggressive side effects (nausea, vomiting, diarrhea , severe pain, weight loss and hair and hair loss). Although these adverse reactions are common, it is always a good idea to communicate to the medical team in case of doubt.
