UNSPSC 51204000: Immunosupressant pyridines

This classification denotes substances that consist of hexahydropyridines, called pyridines, that reduce a human host's humoral and/or cell-mediated defense mechanisms against deviant native cells, foreign organisms, or foreign substances (the human immune response and system thereof), thus the term IMMUNOSUPPRESSANT PYRIDINES.

UNSPSC 51204000 Immunosuppressant pyridines is a Class code that covers pharmaceutical products, though recent state and local solicitations under this code include antimicrobial tablets and opioid-overdose reversal agents rather than immunosuppressants per se. State and local governments procure these pharmaceuticals through warehouse supply contracts and direct-purchase agreements to support public health initiatives, emergency preparedness, and community health programs. The issuing bodies include state health departments and county health authorities, which typically structure purchases as piggyback awards through established cooperative purchasing consortiums or as competitive sealed bids with quarterly or annual delivery schedules.

Illinois Department of Public Health awarded a $2,999,999.11 pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC in August 2026 for Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg tablets under an Invitation for Bid process, with a 12-month initial term and two renewal options. Seminole County, Florida released an Invitation for Bid in June 2026 for annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with a July 26, 2023 response deadline, requiring quarterly deliveries to the Seminole County Community Health Building. Recent activity concentrates in Florida and Illinois, with purchases structured as multi-year agreements and managed through established procurement portals with fixed-fee pricing and standard compliance requirements including drug-free workplace certification and E-Verify.
