UNSPSC 51283803 Quinupristin, a Commodity code, describes pharmaceutical products procured by state and local health agencies, though recent state and local opportunities tagged under this code do not reflect quinupristin-specific solicitations. Instead, the tagged opportunities show state health departments and county health systems sourcing other antibiotics and pharmaceutical supplies through piggyback contracts and direct competitive bidding — including Doxycycline Hyclate and Ciprofloxacin Hydrochloride through cooperative purchasing vehicles, and Naloxone and drug deactivation systems through county health procurement. The actual work under this code encompasses pharmaceutical warehouse orders, bulk pharmaceutical supply agreements, and emergency pharmaceutical procurement supporting community health initiatives, emergency preparedness, and public health response. Issuing bodies include state departments of public health and county health agencies; the Illinois Department of Public Health has appeared as a buyer through MMCAP Infuse consortium contracts.

Recent activity is concentrated in the Southeast and Midwest. The Illinois Department of Public Health awarded a piggyback pharmaceutical warehouse contract to Chartwell Rx LLC on August 28, 2026, for Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg with a total award of $2,999,999.11 over 12 months plus two renewal options, using an Invitation for Bid process. Seminole County, Florida posted an IFB (IFB60459723LAS) on June 30, 2026, seeking 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to the Seminole County Community Health Building; the bid response deadline was July 26, 2023. The code shows limited recent pharmaceutical-specific solicitation activity under its nominal scope; business development professionals should verify current market alignment with the specific active ingredients and delivery models their firms serve.
