This review highlights the various parameters like properties, applications and precautions of radiopharmaceuticals that are now days extensively used as a pharmaceutical formulations to treat high end diseases. Radiopharmaceuticals are used in the field of nuclear medicine as tracers in the diagnosis and treatment of several diseases. The potential of radionuclides in therapy has been recognized for many decades. A number of radionuclides such as iodine131, phosphorous32 and yttrium90 have been in use for the treatment of many benign and malignant disorders. Recently, however, there has been a significant growth of this branch of nuclear medicine with the introduction of a number of new radionuclides and radiopharmaceuticals for the treatment of metastatic bone pain, neuroendocrine and other tumors. In practice, the majority of radiopharmaceuticals are used for diagnosis, but increasingly, highly specific radiotherapeutic agents are being developed which have the potential for delivery of effective treatment, particularly in cancer therapy. Using products of proven quality is vital to achieve successful outcomes in both the diagnostic and therapeutic use of radiopharmaceuticals.
