Radiopharmaceutical therapy by intravenous (IV) administration is a specialized medical procedure that involves the use of radioactive substances to treat various diseases or conditions, particularly in oncology. This therapy necessitates the establishment of an intravenous access line, which allows for the direct delivery of a dose-specific radioisotope into the patient's bloodstream. Once administered, the radioisotope circulates through the body and targets specific organs or tissues that require treatment. The use of radiopharmaceuticals such as Strontium 99 (Metasron), Samarium 153 (Quadramet), and Radium-223 (Xofigo) is particularly notable in this context, as these agents are specifically indicated for alleviating bone pain associated with cancer metastasis. The therapeutic action of these radioisotopes is based on their ability to emit radiation that can destroy cancerous cells or alleviate pain, making this a critical option in the management of metastatic bone pain.
