This page's concept Colesevelam hydrochloride 3750 MG Powder for Oral Suspension RxCUI 866905

Every web starts here: one RxCUI, one fixed meaning in the RxNorm vocabulary.

  1. Ingredients 2

    The active substance itself — no strength, form, or brand attached yet.

    • Colesevelam 141626
    • Colesevelam hydrochloride 141625
  2. Brand names 1

    The same medicine's trade names. A brand name alone says nothing about strength or form.

  3. Dose forms 13

    The ingredient poured into a form — tablet, solution, cream — still without one fixed strength.

Showing up to 8 concepts per family — 14 of 19 stored related concepts drawn.
These are official RxNorm vocabulary relationships — how concepts name and organize the same medicine. They do not establish therapeutic equivalence or substitutability: two concepts appearing in one web is never a statement that products can be swapped.

🔀 Generic ⇄ Brand Crosswalk

The same medicine has an unbranded (generic) identity and one or more brand-name identities — each with its own RxCUI. This is a naming relationship in RxNorm, not a statement that any two products are substitutable.

  • A shared RxCUI does not prove interchangeability. Products mapped to the same concept are not thereby equivalent or substitutable — equivalence is a separate, product-level determination.
  • Listing here does not establish approval or coverage. Appearing in this snapshot is a data observation, not an FDA approval status or a payer coverage decision.
  • Missing data never means zero. A silent dataset (no price, no billing code, no utilization) means no observation — not that the real-world value is zero.
  • Counts describe the mapping footprint. Product, package, and labeler counts are the FDA-listed mapping footprint in this snapshot — not sales, inventory, availability, or market share.
