Radiosensitizer (Radiosensitiyr)

A radiosensitizer is a substance that increases the sensitivity of cells to the effects of ionizing radiation.

The presence of oxygen or other compounds with high electron affinity in tissues increases radiosensitivity. This is due to the fact that such substances are involved in the formation of free radicals during irradiation, which in turn damage cell structures.

Radiosensitizers are used in radiation therapy of oncological diseases to increase the efficiency of irradiation of tumor tissues. They selectively accumulate in the tumor and enhance radiation damage to cancer cells through the formation of toxic radicals. This allows you to reduce the radiation dose to healthy tissue and reduce the side effects of radiation therapy. The most studied radiosensitizers are oxygen and its analogues, nitroimidazoles.

Radiosensitizers are substances that can increase the sensitivity of radiosensitive structures in the human body to radiation. These drugs are used in radiotherapy to increase the effectiveness of treatments for cancer and other diseases.

What is a radiosensitizer? Radiosensitizers are a class of drugs that increase the effect of electromagnetic radiation on the structure and growth of cancer cells. Increased efficiency may result from several mechanisms:

1. Improvement of extravasation of chemotherapeutic agents, including glucoxycol receptors and stimulators of nuclear transduction. 2. Wuxi

Radiosensitizers are used in radiation therapy to increase the effectiveness of radiation on cancer cells. They help increase the dose of radiation, which may be more effective at killing cancer cells.

Radiosensitization occurs because radiation produces free radicals, which can damage DNA and other molecules in cells. Radiosensitizers help increase the number of free radicals and thereby increase the effectiveness of radiation therapy.

One of the most well-known radiosensitizers is the drug idarubicin (Idasenib). It increases the radiosensitivity of tumor cells and is used to treat breast cancer, lung cancer and some other types of cancer.

There are also other radiosensitizers, such as cisplatin and carboplatin, which are used to treat ovarian, prostate and other types of tumors.
