UNSPSC 51314100: Antihistamine or H1 blocker pyrimidines

Antihistamine or H1 blocker drugs made from a family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms.

UNSPSC 51314100 Antihistamine or H1 blocker pyrimidines, a Class code, does not align with the state and local procurement activity currently tagged under it. The recent opportunities posted under this code involve naloxone procurement, direct-to-manufacturer prescription programs, and generic multi-source pharmaceuticals—none of which are antihistamine or H1 blocker pyrimidines. The mismatch suggests either a data-tagging error in the source systems or a significant disconnect between the code's nominal scope and how state and local procurement offices are using it in practice. The issuing bodies include county health departments (Seminole County, Florida), state human services agencies (Texas Health and Human Services Commission), and cooperative purchasing alliances serving multiple jurisdictions (Minnesota Multistate Cooperative Purchasing Alliance, which includes Oregon participation). Scope of work spans naloxone distribution for community health initiatives, exploration of direct-to-manufacturer pharmacy relationships, and generic pharmaceutical supply through authorized wholesaler networks.

Geographic activity appears concentrated in Florida, Texas, and Minnesota, with the MMCAP cooperative spanning multiple states. Representative recent solicitations include Seminole County's IFB60459723LAS (IFB posted June 30, 2026, due July 26, 2023, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries), Texas HHS Commission's RFI HHS0017013 (posted April 3, 2026, exploring direct-to-manufacturer prescription capabilities), and MMCAP's S1070000015802 (RFP posted January 20, 2026, due March 26, 2026, for generic multi-source pharmaceuticals and OTC products through authorized wholesalers effective July 1, 2026). Given the code's stated scope and the nature of recent activity, this code shows little relevant recent procurement opportunity for antihistamine suppliers.
