Radioactive medicines, also known as radiopharmaceuticals, are specially designed compounds that carry radioactive isotopes to specific targets in the body. They play a critical role in modern medical imaging, enabling clinicians to visualize biological processes at the molecular level. By combining chemistry, nuclear physics, and medicine, these agents allow for early diagnosis, disease monitoring, and treatment planning—particularly in oncology, cardiology, and neurology.

Radiopharmaceuticals represent a unique intersection of medicinal chemistry and radiochemistry, combining the principles of drug design with the science of radioactive isotopes. The medicinal chemistry component focuses on optimizing the molecular structure for biological targeting and therapeutic efficacy, while radiochemistry integrates radioactive isotopes to enable imaging or therapeutic functionality. Together, these disciplines create highly specialized medicines that allow for precision diagnosis and treatment.
