UNSPSC 51171800: Antiemetics and antinauseants and antivertigo agents

This classification denotes drugs used to prevent nausea or vomiting. antiemetics act by a wide range of mechanisms. some act on the medullary control centers (the vomiting center and the chemoreceptive trigger zone) while others affect the peripheral receptors.

UNSPSC 51171800 Antiemetics and antinauseants and antivertigo agents is a Class code that does not reflect the work actually being solicited under it in recent state and local opportunities. The single recent posting tagged to this code is Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services — a procurement centered on laboratory testing infrastructure, staffing, and specimen handling rather than pharmaceutical products. The scope includes immunoassay screening with LC/MS/MS or GC/MS confirmation, oral fluid and hair testing methodologies, electronic result reporting, and operation of an Interactive Voice Response system for randomized testing notifications. This represents a fundamental mismatch between the code's pharmaceutical focus and the actual service delivery model being procured.

Collin County posted this RFP on September 25, 2026, with a due date of July 23, 2026 — an apparent dating error in the source — and anticipates award by August 10, 2026. The estimated contract value is $600,000 over two years, with three optional one-year renewals not to exceed five years total. Pricing is structured on a per-test basis across three service models (screening only, confirmation after screening, and screening with automatic confirmation of positives), with annual testing demand projected at approximately 25,031 tests. The successful vendor must maintain lab certification from SAMHSA, TX DPS, or CAP and operate two collection sites in Plano and McKinney during standard business hours plus five Saturdays annually. The code shows little relevant recent activity beyond this single opportunity, which appears to be misclassified in the jurisdiction's taxonomy rather than representative of pharmaceutical procurement under the antiemetics and antinauseants category.
