UNSPSC 51313200: Antihistamine or H1 blocker piperidines

Antihistamine or H1 blocker drugs made from from a family of hexahydropyridines.

UNSPSC 51313200 Antihistamine or H1 blocker piperidines is a Class code that covers pharmaceutical products, though recent state and local solicitations tagged with this code show minimal activity directly aligned with antihistamines or H1 blockers—instead, the code appears to serve as a catch-all for broader pharmaceutical procurement, including naloxone distribution, generic multi-source pharmaceuticals, and over-the-counter products. State and local government purchases under this code span emergency-response medications (naloxone kits), generic pharmaceuticals distributed through institutional pharmacy networks, and OTC products procured for public health initiatives. Issuing bodies include county health departments (Seminole County, Florida), state health and human services agencies (Texas HHS Commission), and multi-state cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance, or MMCAP). The code shows mixed utilization, ranging from single-jurisdiction emergency-response procurement to multi-state cooperative agreements covering dozens of participating jurisdictions across states including Minnesota and Oregon.

Geographic activity clusters in Florida, Texas, and the upper Midwest, with MMCAP serving the broadest reach across state and local entities. Representative recent solicitations include Seminole County's IFB60459723LAS (posted June 30, 2026, due July 26, 2023) seeking 1,900 units of naloxone and 800 Safe Drug Deactivation Systems annually through an IFB process with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida; the Texas HHS Commission's RFI HHS0017013 (posted April 3, 2026) gathering market intelligence on direct-to-manufacturer prescription programs and vendor capabilities for a future Therapeutic Pharmacy Initiative; and MMCAP's RFP S1070000015802 (posted January 20, 2026, due March 26, 2026) establishing multi-award contracts for generic pharmaceuticals and OTC products distributed across participating state and local facilities through authorized wholesalers including AmerisourceBergen (Cencara), Cardinal Health, and Morris & Dickson. The MMCAP RFP emphasizes price competitiveness (75 percent evaluation weight), cGMP and Drug Supply Chain Security Act compliance, and network connections with at least two of three authorized wholesalers. Activity under this code remains episodic rather than continuous; the Seminole County opportunity appears to be a one-time procurement refresh, while the Texas RFI signals exploratory program development rather than immediate contracting intent.
