UNSPSC 51282303: Dirithromycin

This classification denotes a macrolide antibiotic with the molecular formula C42H78N2O14, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 1801D76STL, chemically known as erythromycin, 9-deoxo-11-deoxy-9,11-(imino(2-(2-methoxyethoxy)ethylidene)oxy)-, (9s(r))- but generally known as dirithromycin, which bears US NIH Compound Identifier 5464388. European Medicines Agency schedules Dirithromycin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07232MIG.

UNSPSC 51282303 Dirithromycin is a Commodity code for a specific antibiotic pharmaceutical product, but the recent state and local opportunities tagged under it reflect broader pharmaceutical procurement — state and local health agencies are buying finished pharmaceutical products through piggyback contracts, cooperative purchasing consortia, and competitive bids to support emergency preparedness, disease prevention, and community health programs. The scope of work diverges sharply from the code's nominal focus: the Illinois Department of Public Health procured Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets through an MMCAP Infuse consortium piggyback contract, while Seminole County, Florida solicited Naloxone and drug deactivation systems through a competitive IFB process. Issuing bodies include state health departments and county health authorities; repeat solicitation patterns in the recent record do not emerge from this limited set. The pharmaceutical procurement is driven by regulatory stockpiling requirements, emergency response capacity, and public health intervention programs rather than routine clinical supply.

Activity appears concentrated in the Southeast and Midwest, with recent opportunities in Illinois and Florida. The Illinois Department of Public Health's award to Chartwell Rx LLC under IFB 26482DPHPREPDB53392 closed on September 11, 2026, for a $2,999,999.11 contract spanning 12 months with two renewal options. Seminole County's IFB 60459723LAS, posted June 30, 2026, with response deadline July 26, 2023, sought 1,900 units of Naloxone and 800 deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford; the solicitation required E-Verify compliance, drug-free workplace certification, and compliance with federal standards, with potential FEMA funding noted. Neither opportunity reported set-asides or preference programs. The code shows limited recent activity relative to the breadth of state and local pharmaceutical procurement, suggesting that many jurisdictions tag pharmaceutical buys under broader drug and medical-supply codes rather than to narrow product-specific codes.
