UNSPSC 51291901: Napactadine

This classification denotes a histamine-1 receptor antagonist with the molecular formula C14H16N2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 571S87U90N, chemically known as 2-naphthaleneethanimidamide, n,n-dimethyl-, monohydrochloride but generally known as napactadine, which bears US NIH Compound Identifier 42152. European Medicines Agency schedules Napactadine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09152MIG. The term NAPACTADINE is an International Non-Proprietary Name.

UNSPSC 51291901 Napactadine is a Commodity code that in practice does not align with recent state and local procurement activity. The code's nominal product — napactadine, a selective H1-receptor antagonist — does not appear in any of the three most recent opportunities posted under this code. Instead, those opportunities solicit naloxone and drug deactivation systems, direct-to-manufacturer pharmacy programs, and generic multi-source pharmaceuticals and over-the-counter products. The mismatch between the code label and actual procurement scope signals that this Commodity code carries little decision-relevant activity for vendors focused on the specific pharmaceutical product it nominally describes.

Recent opportunities under the code span health departments and cooperative purchasing alliances across Florida, Texas, and Minnesota. Seminole County, Florida posted an Invitation for Bid (IFB 60459723LAS, due July 26, 2023) for 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries; the Texas Health and Human Services Commission issued a Request for Information (RFI HHS0017013, due April 3, 2026) exploring direct-to-manufacturer prescription programs; and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) released an RFP (S1070000015802, due March 26, 2026) for generic multi-source pharmaceuticals and OTC products distributed through authorized wholesalers to participating state and local facilities in Minnesota and Oregon. Because the posted opportunities do not match the code's stated commodity, vendors should verify whether their actual products or services align with how their target buyers tag procurement in practice rather than relying on this code alone.
