UNSPSC 51282906 Besifloxacin hydrochloride is a Commodity code for a specific antibiotic pharmaceutical product, but recent state and local opportunities posted under this code do not reflect procurement of besifloxacin itself. Instead, the tagged solicitations document purchases of other pharmaceuticals — antibiotics such as doxycycline hyclate and ciprofloxacin hydrochloride through cooperative purchasing vehicles, and naloxone with drug deactivation systems through direct competitive bidding. State and local health departments and county public health agencies use codes in this family to procure bulk pharmaceutical supplies through both piggyback agreements on established multi-state cooperative contracts and standalone IFBs. The issuing bodies in recent activity include state health departments and county-level public health procurement offices.

Recent activity spans Illinois and Florida. The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026 for doxycycline hyclate and ciprofloxacin hydrochloride with a total contract value of $2,999,999.11 over 12 months plus two optional renewal years under an IFB process. Seminole County, Florida posted an IFB 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 due date listed in the source is July 26, 2023, which appears to be a historical entry. The code shows limited recent activity specifically tied to besifloxacin procurement.
