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 is a Commodity code designating a specific antibiotic pharmaceutical product, though recent state and local procurement activity under this code shows minimal direct purchasing aligned with the nominal scope. The two most recent records in the state and local database reflect pharmaceutical procurement by public health and county agencies, but neither solicitation specifically targets colistimethate; instead, they document purchases of unrelated antibiotics (doxycycline and ciprofloxacin in one case) and naloxone with drug deactivation systems in another. State and local governments use pharmaceutical commodity codes to classify medical supply procurement when tagging multi-product vendor contracts or piggyback purchasing agreements, but the records available do not indicate active demand for colistimethate itself at this time.

The Illinois Department of Public Health awarded a completed pharmaceutical warehouse piggyback contract to Chartwell Rx LLC on August 28, 2026, for $2,999,999.11 over a 12-month initial term with two renewal options, sourced through the MMCAP Infuse cooperative purchasing consortium via an Invitation for Bid process. Seminole County, Florida posted an IFB (Solicitation IFB60459723LAS) on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford, with a response deadline of July 26, 2023. Neither opportunity directly solicited colistimethate. The code shows little relevant recent activity; business development professionals should monitor Illinois Department of Public Health and Florida county health procurement channels for future antibiotic purchasing, but colistimethate demand through state and local channels appears dormant under this classification.
