Olitrol, 91 Y

**Olitrol, 91Y** is a drug for the treatment of cancer. It is an isotope product that is a radioactive compound and is used for medical purposes to fight various types of cancer.

**The main effect of the drug is as follows:**

Bismuth Olite Complex - It was developed in the 70s of the last century as a source of chemotherapy that destroys tumor cells. The positive effect of such an isotope compound is due to the penetration of the compound into the DNA of cells, cleavage of their DNA and suppression of tumor growth. The olitic complex works by inhibiting the enzyme telomerase, which disrupts the process of cell division and leads to cell death. The complex also has the ability to change the nuclear apparatus of tumor cells, slowing down their growth and development. In this case, cell structures of any localization fall under the influence of the complex. Isotopes are especially important for head/neck and oral cavity cancers;

Promethazine - this substance belongs to the group of antipsychotics. Such drugs block the transmission of signals between neurons in the brain. An insufficient amount of neurotransmitters, as well as their increased concentration, can both cause deviations from the norm in a person’s psychophysiological state and be a risk for their development. Promethazine antagonizes the sympathetic nervous system, which is responsible for increasing blood pressure. Under conditions of chronic stress, the patient's load on the vessels of all organs and systems of the body increases significantly. Under the influence of Promethazine, you can reduce blood pressure and slightly eliminate neurosis;

Mitomycin C is a drug produced from the Aspergus spp. mushroom. It has cytostatic properties. Fine white powder is sold in pharmacies in the form of 1 dose in polypropylene bottles of 5 mg. MitomycinS is an antitumor drug. Accumulating inside the cell, mitomycin destroys the genetic material necessary for its further reproduction. In other words, it directly affects the DNA molecule of the cell and prevents its division.

Olitrol 91Y is a radiopharmaceutical that has been used in clinical studies to assess the efficacy of radiation therapy. It is a gamma emitter that is characterized by high beta- and gamma-ray emission. The radiation exposure level caused by Olitrol, 91y is minimal while still having significant dose rate. This provides great flexibility in patient positioning, while maintaining good dose distribution in the target volume. Additionally, Olitrol is relatively simple to use during applications with fast radioisotope generators, and it requires lower user skill than other alternatives.

It is used for radiotherapy treatment of various cancer types, such as lung and head and neck cancers, as well as bone and brain tumors. When administered to the patient, it becomes highly concentrated and diffuses into the tumor tissue, while minimizing systemic exposure in healthy tissues nearby. By continuously monitoring radiation exposure to the treatment area, it allows accurate image-guided radiosurgery. Most
