Absorbable gelatin sponge (AGS) (AGS)

Absorbable gelatin sponge (AGS) is a sterile, water-insoluble, and porous biomaterial derived from purified porcine skin gelatin (StatPearls, 2023). While not a traditional molecular target like a receptor or enzyme, it is a critical therapeutic tool used primarily as a topical hemostatic agent to control surgical bleeding when conventional methods are impractical (FDA, 2021). The sponge's unique architecture allows it to absorb up to 40 times its weight in blood, creating a physical environment that accelerates clot formation and stabilizes the wound site (ScienceDirect, 2021). In the field of regenerative medicine, it serves as a three-dimensional scaffold that supports cell attachment, migration, and proliferation, often used in conjunction with growth factors to promote bone or tissue repair (Journal of Biomedical Materials Research, 2020). AGS is highly biocompatible and is typically resorbed by the body through enzymatic degradation within four to six weeks, leaving no permanent foreign material at the site of application (NIH, 2022). It is frequently employed in dental, orthopedic, and neurosurgical procedures where pressure or ligatures are insufficient (PubMed, 2022). Additionally, the scaffold can be loaded with antibiotics or other bioactive molecules to provide localized delivery at the site of injury (Expert Opinion on Drug Delivery, 2021).

The absorbable gelatin sponge acts as a physical matrix that promotes platelet aggregation and provides a structural scaffold for fibrin clot formation (StatPearls, 2023). Its porous nature allows it to absorb blood and fluids, facilitating the activation of the intrinsic coagulation pathway and providing a surface for cell infiltration and tissue ingrowth (PubMed, 2022).
