UNSPSC 51152052 Cyclobenzaprine hydrochloride is a Commodity code that nominally covers a specific muscle-relaxant pharmaceutical product; however, the recent state and local procurement activity tagged under this code does not align with the code's scope. Seminole County, Florida posted an IFB (Solicitation Number IFB60459723LAS) in June 2026 seeking to procure Naloxone and Safe Drug Deactivation Systems—products unrelated to cyclobenzaprine hydrochloride. The mismatch suggests either a coding error in the county's procurement system or that the county is using this code as a catch-all for pharmaceutical and medical-supply acquisitions. State and local governments appear to use this code inconsistently or narrowly; no other recent opportunities under this Commodity code are present in the source material.

The single identified opportunity is with Seminole County, a Florida county government, seeking annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with quarterly deliveries to the Seminole County Community Health Building in Sanford. The IFB closed on July 26, 2023 (a historical date relative to the current posting in June 2026). Vendors must include all shipping and delivery costs in their proposals, maintain workers' compensation and commercial general liability insurance, achieve E-Verify compliance, and pass a three-month probationary period. The contract carries an initial two-year term with an option for one-year renewal and may be federally funded through FEMA. Without additional recent opportunities under this code, geographic spread cannot be characterized beyond Florida, and market activity appears minimal or inactive at present.
