UNSPSC 51161517 Zileuton is a Commodity code under which state and local governments procure pharmaceutical products and related health and safety systems. Recent solicitations tagged to this code show little alignment with its nominal pharmaceutical scope; instead, the opportunities posted reflect procurement of naloxone and drug deactivation systems, instructional materials for career and technical education programs, and galvanized steel pallets. The issuing bodies include county health departments, independent school districts, and county boards of commissioners. The mismatch between the code's pharmaceutical name and the actual scope of recent solicitations suggests either inconsistent tagging by state and local procurement offices or that this code is being used as a catch-all for health-related or emergency-response-adjacent commodities outside its intended pharmaceutical focus.

The three most recent opportunities show activity in Florida and Texas. Seminole County, Florida issued IFB 60459723LAS on June 30, 2026, with responses due July 26, 2023, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually on a two-year contract with one-year renewal option, with quarterly deliveries to the Seminole County Community Health Building in Sanford. Klein Independent School District in Harris County, Texas posted RFP 26-101 on April 17, 2026, due June 5, 2026, for career technical education and advanced academics instructional resources across 17 distinct CTE program areas, with contract beginning September 1, 2026. Hillsborough County Board of County Commissioners in Florida issued ITB 2600197 on March 13, 2026, due April 3, 2026, for galvanized finished steel pallets with an estimated two-year value of $70,264.60. Given the divergence between the code name and actual recent solicitation content, this code warrants close review before pursuit.
