Antineoplastic drugs are a means for treating malignant formations in the body. Often they are prescribed in addition to surgical and radiation methods of fighting disease. The main purpose of such drugs is the destruction of the tumor cell, that is, the provision of a cytotoxic effect.
Antineoplastic agents can be conditionally divided into two large groups – synthetic and natural origin. Synthetic consists of alkylating agents and antimetabolites. They represent a very extensive group of drugs for the treatment of tumors. The main principle of their action is to replace the hydrogen atoms in the cell with an alkyl group and, interfering with the structure of the cell, destroy it.
One of the characteristic features of many antitumor drugs is their immunosuppressive effect, accompanied by the development of infectious complications. At the same time, some antitumor agents (methotrexate, cyclophosphamide, cytarabine) is used as immunosuppressants in autoimmune diseases.
Apply antitumor agents only as directed by an oncologist. Depending on the characteristics of the disease and its course, the efficacy and tolerability of chemotherapy, the dosage and dosage regimen may change, and a combination with other drugs may be introduced.
