UNSPSC 51312800: Antihistamine or H1 blocker phenothiazines

Antihistamine or H1 blocker drugs made from compounds containing dibenzo-1,4-thiazine.

UNSPSC 51312800 Antihistamine or H1 blocker phenothiazines is a Class code that in practice spans pharmaceutical procurement far broader than the nominal category name. State and local governments use this code to solicit generic multi-source pharmaceuticals, over-the-counter products, and emergency-response medications including naloxone and drug deactivation systems. Recent opportunities show county health departments, state health and human services agencies, and multistate cooperative purchasing alliances (MPOs) as the primary issuing bodies. Seminole County, Florida procures naloxone and safe drug deactivation systems through competitive sealed bids; the Texas Health and Human Services Commission gathers market intelligence on direct-to-manufacturer prescription models; and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) — which serves participating jurisdictions across multiple states including Oregon — establishes framework contracts for generic pharmaceuticals and OTC products distributed through authorized wholesalers. Work under this code ranges from tactical, county-level acquisitions of emergency-response drugs to statewide and multistate cooperative framework agreements that establish pricing and supply relationships with manufacturers and wholesalers.

Recent activity concentrates in the South and Upper Midwest. Seminole County's IFB60459723LAS (due July 26, 2023, though posted June 30, 2026) seeks 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. Texas HHS issued RFI HHS0017013 (April 3, 2026) to explore direct-to-manufacturer prescription programs outside traditional pharmacy benefit manager and group purchasing organization channels. MMCAP's multistate RFP S1070000015802 (due March 26, 2026) establishes framework contracts for generic pharmaceuticals and OTC products across participating state and local facilities in Minnesota, Oregon, and other member jurisdictions, requiring vendors to work with authorized wholesalers including AmerisourceBergen (Cencora), Cardinal Health, and Morris & Dickson, and to certify compliance with current Good Manufacturing Practices and the Drug Supply Chain Security Act. The code shows active competition for commodity pharmaceutical supply, cooperative purchasing models, and emergency-response drug procurement at both individual jurisdiction and multistate levels.
