UNSPSC 51191500: Diuretics

This classification denotes agents or substances that promote excretion of urine by influencing human kidney function, commonly known as DIURETICS. The major diuretic types include osmotic (diuretics that increase urine volume by increasing osmotically-active urine solute); potassium sparing (diuretics that limit potassium secretion in urine); sodium chloride symporter inhibitors; and sodium potassium chloride symporter inhibitors.

Diuretics, that is, operate by stimulating he nervous system, by alleviating kidney congestion, by increasing blood pressure, or by increasing or improving liquid transport.

UNSPSC 51191500 Diuretics is a Class code that encompasses pharmaceuticals and chemical products used in medical and municipal treatment applications, though recent state and local solicitations under this code show activity split between generic pharmaceuticals for healthcare distribution and water-treatment chemicals for municipal facilities. The code covers products ranging from OTC medications and brand-name pharmaceuticals to specialized chemical supplies for water pollution control and treatment operations. Issuing bodies include state cooperative purchasing alliances managing multistate pharmaceutical procurement, municipal utilities and water authorities, and healthcare-affiliated public agencies. The work typically involves competitive bidding for supply contracts with detailed product specifications, NDC or chemical standards, delivery schedules, and compliance certifications (cGMP, DSCSA for pharmaceuticals; Connecticut-approved carriers and AM Best ratings for chemical suppliers).

Recent activity spans Minnesota, Connecticut, and Oregon through cooperative purchasing vehicles and direct municipal procurement. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued an RFP on January 20, 2026 (due March 26, 2026) to establish multiple contracts for generic multi-source pharmaceuticals and OTC products distributed across participating state and local government facilities in Minnesota and Oregon, with awarded vendors effective July 1, 2026 and evaluation weighted 75 percent on price competitiveness, 10 percent on fixed pricing, and 5 percent each on administrative compliance, EDI capability, and fee agreement. The City of Meriden, Connecticut solicited bids under IFB B027-15 (due July 29, 2026) for sodium bisulfite chemical supply for its Water Pollution Control Facility, requiring General Liability coverage of $1,000,000 to $2,000,000 and performance and payment bonds. Both opportunities require vendors to maintain comprehensive compliance documentation and accept performance penalties or administrative fees tied to contract performance.
