This classification denotes a serotonin antagonist with the molecular formula C22H22FN3O3.C4H6O6, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 645498QK7H, chemically known as 2,4(1h,3h)-quinazolinedione, 3-(2-(4-(4-fluorobenzoyl)-1-piperidinyl)ethyl)-, (r-(r*,r*))-2,3-dihydroxybutanedioate (1:1) but more generally known as ketanserin tartrate, which bears US NIH Compound Identifier 135348.

UNSPSC 51433605 Ketanserin tartrate is a Commodity code that state and local governments use to procure emergency medical medications, though recent solicitation activity under this code shows state and local bodies purchasing a broader range of advanced life support pharmaceuticals rather than ketanserin tartrate specifically. The City of Tampa's Fire Rescue department, for example, recently solicited sealed bids for advanced life support medications including Labetalol, Epinephrine, Adenosine, and Diltiazem—agents used in acute cardiac and hemodynamic management in prehospital care. State and local fire departments and emergency medical services represent the primary buyer base for medications under this code tier, procuring supplies to stock ambulances, rescue units, and emergency response vehicles. Vendors supplying these medications must meet strict pharmaceutical quality standards, including expiration-date warranties (nine months or longer from acceptance), product liability coverage (365-day minimum warranty against defects), and hazmat documentation (OSHA-compliant Safety Data Sheets).

The City of Tampa's April 2026 IFB for Advanced Life Support Medications (26P00188, response due April 8, 2026) exemplifies current purchasing patterns under this code. The solicitation required delivery within ten calendar days of order, firm pricing including all freight and taxes to the delivery point in Tampa, and a one-year contract term with two optional renewal periods plus three unilateral 30-day extensions. The estimated contract value was $40,000.00, with a Small Local Business Enterprise sheltered-market designation offering a 5 percent bid discount not to exceed $10,000. The geography of activity under this code reflects dispersed municipal fire and EMS procurement concentrated in major urban centers with established emergency services procurement protocols. No additional recent state or local opportunities under this code tier appear in the source.
