This classification denotes a histamine-1 receptor antagonist with the molecular formula C17H23N3O.C4H4O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier R35D29L3ZA, chemically known as n-(p-methoxybenzyl)-n, n-dimethyl-n-.alpha.-pyridylethylenediamine maleate but more generally known as mepyramine maleate, which bears US NIH Compound Identifier 5284451. European Medicines Agency schedules Mepyramine maleate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB14516MIG.

UNSPSC 51311607 Mepyramine maleate is a Commodity code that in practice covers pharmaceutical products purchased by state and local health authorities, though the recent opportunity tagged to this code does not reflect the code's nominal scope. Seminole County, Florida posted an IFB (Solicitation Number IFB60459723LAS) in June 2026 for procuring naloxone and drug deactivation systems—items unrelated to mepyramine maleate, an antihistamine. The misparsing suggests either a data entry error or a broad tagging convention that does not align the code's chemical identity to the actual goods being solicited. State and local health departments and county community health divisions appear to be the primary issuing bodies under pharmaceutical codes in this family, driven by public health mandates and emergency preparedness initiatives.

The available activity is limited to the single Seminole County opportunity, which required annual deliveries of 1,900 units of naloxone and 800 drug deactivation systems on a quarterly schedule to the Seminole County Community Health Building in Sanford, Florida. The IFB closed July 26, 2023 (note: the posting date shown as June 30, 2026 conflicts with the 2023 close date in the source), and the contract included a two-year initial term with a one-year renewal option, subject to a three-month probationary period. Vendors had to provide unit costs, comply with drug-free workplace and E-Verify requirements, and carry workers' compensation, commercial general liability, and professional liability insurance. The procurement was potentially FEMA-funded, introducing federal environmental compliance requirements. Because the code shows minimal relevant recent activity and the single posted opportunity is tangentially related at best, pursue opportunities under this code only after confirming that issuing bodies are actually buying mepyramine maleate products rather than other pharmaceutical categories.
