UNSPSC 51131814 Aprotinin is a Commodity code that describes a specific pharmaceutical agent used in surgical and medical settings to control bleeding. However, the most recent state and local contract opportunity tagged under this code shows no relevant recent activity — Sourcewell's May 2026 RFP #061626 for law enforcement equipment is unrelated to the pharmaceutical scope of the code and appears to be a classification mismatch in the underlying procurement system. No recent state or local solicitations for aprotinin or related hemostatic agents are present in the available opportunities block.

The mismatch between the code's pharmaceutical scope and the law enforcement equipment solicitation suggests that this Commodity code either sees minimal activity in state and local procurement or that jurisdictions are not systematically tagging pharmaceutical purchases under UNSPSC 51131814. Without representative opportunities grounded in actual aprotinin procurement, geographic spread and issuing-body patterns cannot be reliably characterized from this source. Firms evaluating this code should verify current activity through direct outreach to state pharmaceutical procurement offices, hospital systems, and health department contracts divisions, as well as through cooperative purchasing vehicles like Sourcewell and state healthcare consortia that may operate outside the recent-opportunities visibility shown here.
