UNSPSC 51292925 Mirtazapine hemihydrate is a Commodity code that maps poorly to the recent state and local opportunities on file. The code's nominal scope — a specific antidepressant pharmaceutical ingredient — does not align with the recent solicitations, which address naloxone procurement, direct-to-manufacturer pharmacy programs, and multi-source generic pharmaceuticals and OTC products through cooperative purchasing. State and local governments do buy pharmaceuticals at scale through their health departments, corrections systems, community health facilities, and cooperative purchasing vehicles, but the opportunities tagged to this code do not target mirtazapine hemihydrate specifically or reflect demand for a single active pharmaceutical ingredient as distinct from finished-dose pharmaceuticals, generics, or OTC products. The recent record shows minimal or no relevant activity under this specific commodity code.

The three opportunities in the file span different pharmaceutical procurement strategies but none address mirtazapine. Seminole County, Florida issued IFB 60459723LAS in June 2026 to procure naloxone and drug deactivation systems with a July 26, 2023 response deadline. Texas Health and Human Services Commission posted RFI HHS0017013 in April 2026 to explore direct-to-manufacturer prescription programs. Minnesota's MMCAP cooperative purchasing vehicle issued an RFP (S1070000015802) in January 2026 for multi-source generic pharmaceuticals and OTC products with a March 26, 2026 deadline, serving state and local government facilities across participating states including Oregon. If mirtazapine hemihydrate procurement is a target market, activity under this specific code warrants close monitoring, as recent state and local demand patterns are not yet visible in the available opportunities.
