Hemostatic Powder Spray TC-325
From Wikipedia, the free encyclopedia
Hemostatic Powder Spray TC-325 (Hemospray or TC-325) is an inert, highly absorptive mineral agent which is used for the treatment of gastrointestinal bleeding. Applied during endoscopy to bleeding lesions, TC-325 is derived from bentonite, and is used to achieve hemostasis (control of bleeding) by absorbing water and creating a barrier that leads to mechanical tamponade (pressure) and concentration of clotting factors, resulting in enhanced coagulation (clotting of blood).[1] TC-325 was approved for gastrointestinal bleeding from causes other than gastric or esophageal varices (e.g., nonvariceal bleeding). TC-325 results in immediate control of bleeding in 91-93% of cases.[2][3] Technical success has gradually increased between 2011 and 2019, which may be due to device improvements or physician familiarity with the application of TC-325.[2]
