UNSPSC 51283106 Polymyxin B is a Commodity code whose recent activity reflects state and local procurement of pharmaceuticals and medical supplies that extends well beyond the narrow chemical agent implied by the code name. State and local issuing bodies are acquiring generic pharmaceuticals, over-the-counter products, naloxone and drug deactivation systems, and medical and first aid supplies through cooperative purchasing vehicles, direct procurement, and competitive bidding. The issuing bodies soliciting under this code include state health and human services departments, county health agencies, municipal fire departments, and multistate cooperative purchasing alliances. Work ranges from individual jurisdictional acquisitions of emergency medical supplies to large multistate framework agreements for generic pharmaceutical distribution across multiple agencies and jurisdictions.

Recent activity spans Florida, Texas, Minnesota, and Oregon.
