How does Avitene Flowable differ from Avitene Flour?

• A. Flowable is a dry powder; Flour is a ready-to-use paste.
• B. Flowable is mixed with sterile water until a paste forms.
• C. Flowable is mixed with liquid to create a paste; Flour is a dry powder applied directly.
• D. Flowable is ready-made gel; Flour is powder.

Answer: (C)

Flowable and Flour differ in how they are prepared and applied. Avitene Flowable is designed to be mixed with a liquid to form a paste or slurry, which allows it to be delivered into irregular wound surfaces or spaces and stay in place as it adheres to the bleeding site. Avitene Flour is a dry powder that is sprinkled directly onto the bleeding surface without mixing, forming a hemostatic matrix from contact with blood. This distinction explains why Flowable is used when a paste is needed to contour to the wound, while Flour is used for straightforward surface application. The other statements misstate the form or handling of the products.
