Radiopharmaceuticals are often used to diagnose certain types of tumors and organ problems. They may also be used to treat conditions like cancer. These medications work by using small amounts of radioactive material to target specific cells in your body, helping to diagnose or treat the condition. Radiopharmaceuticals come in different forms, including oral and injectable options. Examples include Lutathera (lutetium Lu 177 dotatate) and Drax Exametazime (technetium Tc 99m exametazime).
