UNSPSC 51281711 Amoxicillin hydrate is a Commodity code representing specific antibiotic pharmaceutical products procured by state and local health agencies. The recent state and local procurement activity tagged under this code, however, does not align with amoxicillin purchases. Instead, the opportunities posted reflect procurement of other pharmaceuticals—doxycycline hyclate and ciprofloxacin hydrochloride tablets through a consortium piggyback contract, and naloxone with drug deactivation systems for community health support—indicating a potential code-tagging mismatch in state and local procurement systems. State and local health departments, including state departments of public health and county health agencies, use piggyback contracts and direct solicitations to source pharmaceutical products through cooperative purchasing vehicles such as MMCAP Infuse.

Recent activity appears concentrated in the Upper Midwest and Southeast. The Illinois Department of Public Health awarded a $2,999,999.11 piggyback pharmaceutical warehouse contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026, covering doxycycline hyclate 100mg tablets and ciprofloxacin hydrochloride 500mg tablets under Invitation for Bid 26482DPHPREPDB53392 with an initial 12-month term and two one-year renewal options. Seminole County, Florida posted an IFB on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually for quarterly delivery to the Seminole County Community Health Building in Sanford, with response due July 26, 2023. The code shows limited recent activity clearly matching amoxicillin specifically; prospective vendors should verify code application in current solicitations before submitting bids.
