AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
AN-SULFUR COLLOID (Technetium Tc 99m Sulfur Colloid) is a radiopharmaceutical diagnostic imaging agent approved in 1978 that uses radioactive technetium decay to visualize lymphatic, reticuloendothelial, and gastrointestinal function. Following injection or oral administration, it localizes to specific tissues and organs, enabling detection of lymph node involvement, shunt patency, and gastroesophageal reflux. The drug functions as a tracer agent for nuclear medicine imaging across multiple clinical applications.
LOE Approaching
Product approaching loss of exclusivity with moderate competitive pressure (30/100), suggesting a defending or transition-focused team rather than growth-oriented expansion.
Mechanism of Action
99m decays by isomeric transition, emitting a photon that can be detected for imaging purposes. Following subcutaneous injection, Technetium Tc 99m Sulfur Colloid enters the lymphatic capillaries and is transported with lymph to lymph nodes. However, when there is massive nodal metastatic…
