UNSPSC 51171633: Lubiprostone

This classification denotes a prostaglandin analogue with the molecular formula C20H32F2O5, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 7662KG2R6K, chemically known as prostan-1-oic acid, 16,16-difluoro-11-hydroxy-9,15-dioxo-, (11alpha)- but generally known as lubiprostone, which bears US NIH Compound Identifier 157920. European Medicines Agency schedules Lubiprostone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB32077.

UNSPSC 51171633 Lubiprostone, a Commodity code, shows minimal recent state and local procurement activity aligned with the pharmaceutical product itself. The single recent opportunity posted under this code—Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services, due July 23, 2026—concerns laboratory testing services, specimen collection staffing, and confirmation methodologies (immunoassay screening, LC/MS/MS, and GC/MS confirmation), not lubiprostone acquisition or supply. The mismatch between the code's pharmaceutical scope and the actual work being solicited suggests either a data-entry error in the source opportunity or a misalignment in how the county tagged the procurement.

Absent additional evidence of lubiprostone procurement under this code from state and local bodies, no meaningful issuing-body mix or geographic concentration can be established from the source. The Collin County opportunity represents the only recent posted activity; it carries an estimated contract value of $600,000, a two-year term commencing September 1, 2026, with three optional one-year renewals. Until recent opportunities demonstrate consistent state and local purchasing of lubiprostone as a pharmaceutical commodity, the code shows little actionable activity for vendors serving that market.
