European Medicines Agency schedules ampicillin trihydrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB00509MIG.

UNSPSC 51281717 Ampicillin trihydrate is a Commodity code that covers specific pharmaceutical active ingredients and finished dosage forms, but recent state and local solicitations tagged under this code do not reflect procurement of ampicillin itself. Instead, the opportunities posted under this taxonomy span a broad range of pharmaceutical and medical products — naloxone, generic multi-source pharmaceuticals and over-the-counter products, and emergency medical supplies including respiratory equipment and cardiac monitoring devices. The issuing bodies include state health and human services commissions, county public health departments, city fire departments, and multistate cooperative purchasing alliances. This pattern suggests that the code's application at state and local level has drifted significantly from the narrow chemical substance the code nominally names, or that the opportunities have been miscoded by issuing bodies unfamiliar with the UNSPSC hierarchy.

Recent activity spans multiple regions: Minnesota (through the multistate MMCAP cooperative), Texas (Texas HHS Commission), and Florida (Seminole County). Representative solicitations include Minnesota's MMCAP Request for Proposal for Generic Multi Source Pharmaceuticals and OTC Products, due March 26, 2026, which seeks manufacturers to supply generic drugs through three authorized wholesalers with responses evaluated on pricing competitiveness (75 percent), fixed pricing, EDI capability, and cGMP and DSCSA compliance; Seminole County, Florida's Invitation for Bid for Naloxone and Drug Deactivation Systems (IFB 60459723LAS), posted June 30, 2026, requiring 1,900 units of naloxone and 800 deactivation systems annually with quarterly deliveries and a response deadline of July 26, 2023; and the City of Tampa's bid for medical and first aid supplies for the Tampa Fire Department Rescue Division (Bid 26-P-00145), due March 13, 2026, comprising 169 line items with an estimated contract value of $700,000.00 and a sheltered-market designation for certified Small Local Business Enterprises with a 5 percent bid discount. The Texas HHS Commission also issued a Request for Information (RFI) on Direct-to-Manufacturer Prescriptions in April 2026 to explore vendor capabilities for establishing direct relationships between state pharmacy benefit programs and pharmaceutical manufacturers outside traditional pharmacy benefit manager and group purchasing organization channels.
