UNSPSC 51386403 Balsalazide disodium is a Commodity code that shows minimal relevance to recent state and local procurement activity. The code describes a specific pharmaceutical active ingredient used in inflammatory bowel disease treatment, yet the single recent opportunity posted under it—Seminole County, Florida's IFB60459723LAS—solicits naloxone and drug deactivation systems for community health initiatives, work that falls outside the scope of balsalazide procurement. State and local governments buying under this code are difficult to characterize from available recent opportunities, as the posted solicitation does not represent actual balsalazide purchasing.

The mismatch between the code's pharmaceutical specificity and the naloxone-focused opportunity suggests either a classification error in the posting or minimal actual demand for balsalazide through state and local procurement channels. Seminole County's IFB, posted June 30, 2026 with a response deadline of July 26, 2023, calls for 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida—a procurement unrelated to balsalazide disodium. Without additional recent opportunities correctly tagged to this code, there is insufficient activity to assess geographic spread, issuing-body patterns, or genuine market demand for balsalazide procurement at the state and local level.
