🕸️ Concept Web — How Gabapentin 400 MG Oral Capsule Connects

One RxCUI never lives alone. Follow the path from the raw ingredient down to the exact strength-and-form concepts FDA products carry — every stop is a real RxNorm concept with its own identifier. Hover or focus any chip for what it means.
This page's concept Gabapentin 400 MG Oral Capsule RxCUI 310432

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

  1. Ingredients 1

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

    • Gabapentin 25480
  2. Brand names 2

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

    • Neurontin 196498
    • Relgaabi 2739002
  3. Dose forms 12

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

    • Gabapentin Oral Capsule 378100
    • Gabapentin Oral Product 1156681
    • Gabapentin Pill 1156682
    • Gabapentin Oral Capsule [Neurontin] 366770
    • Gabapentin Oral Capsule [Relgaabi] 2739006

    • Neurontin Pill 1182286
    • Relgaabi Oral Product 2739004
    • +4 more in this family
  4. Clinical & branded drugs 5

    Ingredient + strength + dose form. These are the concepts real FDA products actually carry.

Showing up to 8 concepts per family — 16 of 20 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.
