UNSPSC 51284400: Fifth generation cephalosporins

This classification denotes the original variety of broad-spectrum antibiotics originally isolated from the fungus cephalosporium acremonium, and which contain thia-azabicyclo-octenecarboxylic acid or 7-aminocephalosporanic acid, hence the term CEPHALOSPORIN. These differ from other Cephalosporins both in their chronological development and that these are effective against Methicillin-Resistant Staphylococcus aureus, a strain of Staphylococcus aureus that is non-susceptible to the action of methicillin.

The mechanism of resistance usually involves modification of normal or the presence of acquired penicillin binding proteins.

UNSPSC 51284400 Fifth generation cephalosporins is a Class code, but the recent state and local opportunities posted under it do not align with its nominal scope. The code's definition targets a specific antibiotic drug family, yet the four most recent solicitations — a Seminole County naloxone and drug deactivation systems procurement, a Texas HHS pharmacy direct-to-manufacturer RFI, a Tampa Fire Department medical and first aid supplies IFB, and a Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) generic multi-source pharmaceuticals and OTC products RFP — span naloxone, emergency medical consumables, pharmaceutical supply chain operations, and broad-based generic drug and OTC sourcing. The code shows little relevant recent activity aligned to fifth generation cephalosporins specifically. Issuing bodies soliciting under this code include county health departments, state health and human services commissions, municipal fire departments, and multi-state cooperative purchasing alliances, reflecting fragmented procurement across health systems, emergency response, and centralized state pharmaceutical buying.

Recent activity clusters in three states: Florida (Seminole County's naloxone procurement, posted June 30, 2026, IFB 60459723LAS, due July 26, 2023), Texas (HHS RFI for direct-to-manufacturer prescription programs, posted April 3, 2026), and Minnesota (MMCAP generic pharmaceuticals RFP, posted January 20, 2026, due March 26, 2026, extending to participating jurisdictions including Oregon). The Tampa Fire Department's medical and first aid supplies IFB (26P00145, posted March 25, 2026, due March 13, 2026, estimated at $700,000) is designated exclusively for certified Small Local Business Enterprises with a 5 percent bid discount. The mismatch between the code's antibiotic-specific definition and the actual procurement mix — naloxone, emergency supplies, and multi-source generics — suggests potential data-entry errors in tagging these opportunities or a very broad institutional practice of using this code for pharmaceutical and medical-supply buys regardless of active ingredient or drug class.
