UNSPSC 51312101: Oxomemazine

This classification denotes an antimuscarinic agent with the molecular formula C18H22N2O2S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 305MB38V1C, chemically known as 10h-phenothiazine-10-propanamine, n,n,beta-trimethyl- but generally known as oxomemazine, which bears US NIH Compound Identifier 5574. European Medicines Agency schedules Oxomemazine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09549MIG.

UNSPSC 51312101 Oxomemazine, a Commodity code, does not reflect what state and local governments are actually procuring under this classification. The recent opportunities tagged to this code involve naloxone procurement, direct-to-manufacturer pharmacy programs, and multi-source generic pharmaceuticals—none of which are oxomemazine. The code shows a significant mismatch between its nominal scope and the work being solicited.

The three recent opportunities reflect pharmaceutical supply and pharmacy benefit management across county health systems, state health agencies, and cooperative purchasing alliances. Seminole County, Florida (IFB 60459723LAS, due July 26, 2023) sought 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to support community health initiatives. The Texas Health and Human Services Commission (RFI HHS0017013, posted April 3, 2026) issued an exploratory Request for Information on establishing direct-to-manufacturer prescription channels outside traditional pharmacy benefit manager arrangements. The Minnesota Multistate Cooperative Purchasing Alliance (RFP S1070000015802, due March 26, 2026) solicited generic multi-source pharmaceuticals and OTC products through authorized wholesalers for distribution across participating state and local government facilities, including Oregon. Activity spans Florida, Texas, and multi-state cooperative arrangements; the code shows minimal relevant recent procurement activity with clear categorical misalignment.
