UNSPSC 51283500: Penicillinase-resistant penicillins

This classification denotes highly-target-specific, second-generation penicillins chiefly employed against staphylococcal infections, especially against Staphylococcus aureus, and which are not rendered inactive by penicillinas, a beta-lactamase or bacteria-produced enzyme preferentially cleaving penicillins.

UNSPSC 51283500 Penicillinase-resistant penicillins is a Class code that encompasses antibiotic pharmaceuticals procured through state and local health agencies, though recent activity shows substantial misalignment between the code's nominal scope and the work actually being tagged under it. The Illinois Department of Public Health awarded a $2,999,999.11 piggyback pharmaceutical warehouse contract through the MMCAP Infuse consortium to Chartwell Rx LLC covering Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—neither of which are penicillinase-resistant penicillins—with an initial 12-month term and renewal options for years 2 and 3. State and local health departments and county public health authorities drive procurement under this code, typically sourcing medications through cooperative purchasing vehicles or piggyback arrangements rather than direct open solicitations. Demand reflects ongoing public health needs including infectious disease treatment and emergency response stockpiling.

Geographic activity centers on Illinois and Florida based on recent postings, though the sample size is limited. The Illinois Department of Public Health remains an active buyer through consortium agreements, while Seminole County, Florida issued an IFB (IFB60459723LAS, due July 26, 2023) for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually—a procurement also miscoded under this UNSPSC despite involving opioid antagonists rather than penicillins. The code exhibits minimal relevant recent activity and shows a pattern of pharmaceutical procurements tagged without regard to the specific antibiotic family the code nominally describes, signaling potential classification drift in state and local coding practices.
