UNSPSC 51435000: Combination calcium channel blockers

This classification denotes combination drugs that act by selective inhibition of calcium influx through cell membranes or on the release and binding of calcium in intracellular pools, hence the term calcium channel blockers. Typical combination calcium channel blocker constituents are amlodipine and sodium chloride.

UNSPSC 51435000 Combination calcium channel blockers is a Class code that encompasses pharmaceutical products used in emergency medical settings, specifically combination-formulation antihypertensive agents. State and local governments procure these medications primarily through fire rescue departments and emergency medical services to stock advanced life support kits and ambulance supplies. The actual procurement activity under this code reflects the broader emergency pharmaceuticals supply chain rather than calcium channel blockers in isolation — solicitations frequently bundle multiple medication categories including vasoconstrictors, antiarrhythmics, and other critical-care agents under single purchase orders. Issuing bodies acquiring these products are predominantly city and county fire rescue operations, emergency medical services divisions, and health departments operating pre-hospital care systems.

The City of Tampa's Purchasing Department issued IFB 26P00188 in April 2026 on behalf of Tampa Fire Rescue, soliciting advanced life support medications including 1,020 units of Diltiazem 25mg vials (a calcium channel blocker), along with Labetalol, Epinephrine, and Adenosine, with a response date of April 8, 2026 and an estimated contract value of $40,000.00. The solicitation required firm pricing inclusive of shipping, delivery within ten calendar days, nine-month minimum shelf life, and annual warranty coverage, with a one-year contract term plus two optional one-year renewals and three optional 30-day extensions. The opportunity carried a Small Local Business Enterprise sheltered market designation with a 5 percent bid discount not to exceed $10,000. Recent activity under this code is concentrated in Florida; no additional state and local opportunities are documented in the source.
