UNSPSC 51283104: Colistimethate

This classification denotes an antimicrobial solution, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier XW0E5YS77G. European Medicines Agency schedules Colistimethate sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06801MIG. Colistimethate sodium generally arises in the molecular formula C57H103N16NA5O28S5.

UNSPSC 51283104 Colistimethate, a Commodity code, does not reflect the actual pharmaceutical and medical supply categories that state and local governments are soliciting under this record. The recent opportunities tagged to this code span naloxone distribution systems, generic multi-source pharmaceuticals and OTC products, medical and first aid supplies for emergency response, and therapeutic pharmacy initiatives—none of which are colistimethate (a nebulized antibiotic for cystic fibrosis and chronic infections). The mismatch suggests that the source record misclassifies these procurements or that colistimethate itself rarely appears as a standalone procurement line item in state and local markets. State procurement offices, county health departments, fire departments, and cooperative purchasing alliances issue these solicitations, but the code's nominal scope does not align with the work actually being bought.

Recent activity clusters in Florida, Texas, and Minnesota through mixed issuing bodies: Seminole County (naloxone and drug deactivation systems, IFB, July 2026 response), the Texas Health and Human Services Commission (direct-to-manufacturer pharmacy initiative RFI, April 2026), the City of Tampa Fire Department (medical and first aid supplies, IFB, March 2026, estimated $700,000, sheltered for Small Local Business Enterprises), and the Minnesota Multistate Cooperative Purchasing Alliance (generic pharmaceuticals and OTC products RFP, March 2026 response, through authorized wholesalers including Cencora and Cardinal Health). The code shows material recent volume in emergency medical supplies and pharmacy benefit contracting, but the pharmaceutical and device categories active in the market do not map cleanly to colistimethate. Firms pursuing this code should verify actual commodity alignment with issuing bodies' specifications rather than rely on the UNSPSC designation.
