UNSPSC 51282316: Erythromycin estolate

European Medicines Agency schedules Erythromycin estolate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB01941MIG.

UNSPSC 51282316 Erythromycin estolate is a Commodity code whose nominal scope — a single antibiotic pharmaceutical compound — diverges sharply from the actual state and local procurement activity tagged under it. Recent opportunities identified under this code involve naloxone procurement, medical and first aid supplies for fire rescue operations, multi-source generic pharmaceuticals and OTC products through cooperative purchasing, and direct-to-manufacturer prescription program exploration. The code shows little procurement activity specifically for erythromycin estolate; state and local governments are instead using this code designation (or misusing it in their tagging systems) to solicit broader pharmaceutical, medical supplies, and health-service contracting. The issuing bodies span health departments, fire rescue divisions, cooperative purchasing alliances, and state health agencies — Seminole County, Florida; the City of Tampa; the Texas Health and Human Services Commission; and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) administering on behalf of Minnesota and other participating states. These are representative of the typical mix of municipal, county, and multi-state cooperative procurement vehicles engaged in pharmaceutical and medical-supplies contracting.

Geographic activity centers on Florida (Seminole County, Tampa), Texas (HHS Commission), and Minnesota (MMCAP cooperative spanning multiple states including Oregon), with no concentration in any single region. Representative recent opportunities include Seminole County's IFB 60459723LAS posted June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with a response deadline of July 26, 2023 (noted in source as July 26, 2023, though post date is June 30, 2026); the City of Tampa's ITB 26P00145 posted March 25, 2026, for 169 line items of medical and first aid supplies for the Tampa Fire Department Rescue Division with a deadline of March 13, 2026 and an estimated contract value of $700,000, sheltered to certified Small Local Business Enterprises with a 5 percent bid discount; and MMCAP's RFP S1070000015802 for generic multi-source pharmaceuticals and OTC products with a proposal deadline of March 26, 2026. The Texas HHS Commission's April 2026 RFI on direct-to-manufacturer prescriptions signals future formal procurement intent but does not yet represent an active competitive solicitation.
