UNSPSC 51151604: Trihexyphenidyl

This classification denotes an antiparkinsonian agent and antimuscarinic agent with the molecular formula C20H31NO, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6RC5V8B7PO, chemically known as 1-piperidinepropanol, alpha-cyclohexyl-alpha-phenyl- but generally known as trihexyphenidyl, which bears US NIH Compound Identifier 5572. European Medicines Agency schedules Trihexyphenidyl in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB11295MIG.

UNSPSC 51151604 Trihexyphenidyl is a Commodity code nominally for a specific pharmaceutical active ingredient, but the recent state and local opportunities tagged under it show no procurement activity aligned with that product. Instead, the solicitations present a mismatch: Seminole County, Florida's IFB60459723LAS calls for naloxone and drug deactivation systems, and the Texas Health and Human Services Commission's RFI HHS0017013 addresses direct-to-manufacturer prescription programs and pharmacy benefit management—neither of which involves trihexyphenidyl procurement. The code shows little relevant recent activity grounded in its nominal pharmaceutical scope.

The two posted opportunities reflect different issuing-body types and procurement mechanisms. Seminole County, a county health authority, used a competitive IFB with a July 26, 2023 response deadline for naloxone and safe drug deactivation systems with quarterly deliveries. The Texas HHS Commission, a state agency, issued an exploratory RFI posted April 3, 2026 seeking vendor capabilities for direct-to-manufacturer prescription programs—a preliminary market-intelligence phase rather than a binding solicitation. No award values, contract terms, or set-asides are specified in either opportunity as relevant to the code. Geographic activity appears concentrated in Florida and Texas based on these two postings alone, but the mismatch between the code's intended scope and the actual work being solicited suggests either a data-classification error or that this code does not currently receive regular state and local procurement volume.
