UNSPSC 51191507 Spironolactone is a Commodity code that captures pharmaceutical and chemical products used in state and local healthcare, correctional, and water-treatment operations. Recent solicitations show the code encompasses not only branded pharmaceuticals but also industrial chemicals and parenteral products — intravenous solutions, nutrition formulations, and medical equipment — procured by correctional health systems, water utilities, and county infrastructure departments. State and local buyers use this code when purchasing regulated pharmaceutical and chemical commodities for institutional operations, medical delivery, and process compliance. Issuing bodies include state departments of corrections, county purchasing offices, and municipal utilities. The Washington State Department of Corrections and Broward County, Florida appear as repeat or notable recent users, though the source does not indicate systematic concentration among specific jurisdictions.
