Nimorazole is primarily used as an antiprotozoal and radiosensitizing agent in medical treatments. It is effective against anaerobic bacteria and protozoa, making it valuable in treating infections caused by these microorganisms. In oncology, nimorazole is employed to enhance the effectiveness of radiotherapy, particularly in hypoxic tumor cells, by sensitizing them to radiation. This application is crucial in improving outcomes for patients undergoing cancer treatment, especially in cases where tumors are resistant to radiation due to low oxygen levels. Additionally, nimorazole has been investigated for its potential in managing certain parasitic infections, contributing to its role in infectious disease therapy.
