AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Technetium Tc 99m Sulfur Colloid is a radiopharmaceutical diagnostic imaging agent approved in 1974 that uses radionuclide decay to detect photons for diagnostic imaging across multiple organ systems. The product works by localizing to different tissues depending on route of administration: lymphatic system (subcutaneous), peritoneal fluid (intraperitoneal), reticuloendothelial system (intravenous), or remaining in GI tract (oral). It enables assessment of lymph node involvement, shunt patency, RES function, and detection of gastric aspiration.
LOE Approaching
Legacy diagnostic product approaching end-of-life with minimal commercial growth trajectory and likely small, maintenance-focused team.
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…
