UNSPSC 51281682 Viomycin trihydrochloride is a Commodity code that nominally names a specific antibiotic pharmaceutical, yet recent state and local solicitations tagged under this code show little alignment with viomycin procurement itself. Instead, the opportunities reflect broad pharmaceutical, medical supply, and pharmacy benefit administration work spanning naloxone and drug deactivation systems, first-aid and emergency-response supplies, generic pharmaceuticals and OTC products, and direct-to-manufacturer prescription programs. The actual buying activity under this code designation spans multiple issuing bodies—county health departments, city fire and rescue services, state pharmacy benefit programs, and multistate cooperative purchasing alliances—each procuring different product and service categories. The mismatch between the code's nominal scope and the recent opportunities suggests either miscoding of opportunities or a code assignment methodology that does not track narrowly pharmaceutical procurement.

Recent opportunities show activity across Florida, Texas, Minnesota, and Oregon. Seminole County, Florida issued IFB 60459723LAS (posted June 30, 2026, response due July 26, 2023) for 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the county community health building. The City of Tampa issued IFB 26P00145 (posted March 25, 2026, response due March 13, 2026) for 169 line items of medical and first-aid supplies totaling an estimated $700,000 for the Fire Department Rescue Division, with a sheltered-market set-aside for certified Small Local Business Enterprises and a 5 percent bid discount capped at $10,000. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) issued RFP S1070000015802 (posted January 20, 2026, response due March 26, 2026) for generic multi-source pharmaceuticals and OTC products distributed across state and local facilities including Oregon, requiring distribution through specified wholesalers and effective July 1, 2026. The Texas Health and Human Services Commission issued RFI HHS0017013 (posted April 3, 2026, response due April 3, 2026) to gather vendor capabilities for direct-to-manufacturer prescription programs supporting self-insured state pharmacy benefit management.
