AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
AN-SULFUR COLLOID (Technetium Tc 99m Sulfur Colloid) is a radiopharmaceutical diagnostic agent approved in 1978 that uses technetium-99m decay to emit photons for imaging purposes. It functions through multiple routes (subcutaneous, intraperitoneal, intravenous, oral) to visualize lymph node involvement, assess peritoneal shunt patency, image reticuloendothelial system structures, and detect gastric aspiration. The mechanism varies by route: lymphatic transport for nodal imaging, peritoneal fluid clearance assessment, RES uptake for systemic imaging, and non-absorption for esophageal transit studies.
LOE Approaching
This legacy diagnostic product is approaching loss of exclusivity with moderate competitive pressure (30%), indicating a contracting team and focus on cost management rather than growth initiatives.
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…
