Which term describes a drug category used in nuclear medicine?

• A. Over-the-counter drug
• B. Radiopharmaceutical
• C. Antibiotic
• D. Analgesic

Answer: (B)

Radiopharmaceuticals are drugs used in nuclear medicine. They couple a biologically active pharmaceutical with a radioactive isotope so the compound can be tracked inside the body for imaging or deliver targeted radiation to treat disease. This allows doctors to visualize specific organs or processes, or to administer therapy using the emitted radiation. The other options describe non-radioactive medicines: over-the-counter drugs are non-prescription, antibiotics treat infections without radioactive components, and analgesics relieve pain without involving radioactive material.
