UNSPSC 51284900 Combination antimicrobials is a Class code under which state and local governments procure pharmaceutical products combining multiple active antimicrobial agents—principally antibiotics and overdose-reversal medications—for public health and emergency response use. Recent solicitations show state and local health agencies buying combination antibiotic products (such as Doxycycline Hyclate and Ciprofloxacin Hydrochloride) for emergency preparedness stockpiles and naloxone-based overdose-reversal systems paired with drug deactivation technology for community health support. Issuing bodies include state health departments and county public health agencies, with health departments using cooperative purchasing consortiums to aggregate demand and reduce unit cost.

Activity under the code appears concentrated in the Southeast and Midwest. The Illinois Department of Public Health awarded a $2,999,999.11 three-year piggyback pharmaceutical warehouse contract through the MMCAP Infuse consortium to Chartwell Rx LLC in August 2026 for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets, selected via competitive Invitation for Bid. Seminole County, Florida issued an Invitation for Bid (IFB 60459723LAS) posted June 30, 2026 for annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with quarterly deliveries, a two-year initial term with one-year renewal option, and a response deadline of July 26, 2026. Both procurements require electronic bid submission, include delivery cost responsibility on the vendor, and impose drug-free workplace and E-Verify compliance requirements.
