Bixibat Brand Facts

Critical Clarification: Bixibat is NOT Linaclotide

Bixibat is a topical analgesic for temporary relief of minor muscle and joint aches, NOT a constipation medication. 1

The FDA-approved indication for bixibat (oral formulation) is for temporary relief of minor aches and pains of muscles and joints associated with arthritis, simple backache, strains, sprains, muscle soreness and stiffness. 1


Important Note on Terminology Confusion

The expanded question incorrectly conflates "Bixibat" with "linaclotide" - these are completely different medications:

Bixibat

  • Indication: Topical pain relief for musculoskeletal conditions 1
  • Route: Topical/oral (depending on formulation) 1
  • Mechanism: Analgesic for minor aches and pains 1

Linaclotide (Linzess) - A Different Drug Entirely

  • Indication: Chronic idiopathic constipation (CIC) and irritable bowel syndrome with constipation (IBS-C) 2, 3
  • Route: Oral only 2
  • Mechanism: Guanylate cyclase-C agonist that increases intestinal fluid secretion 2, 3

Bixibat Administration and Use

For the actual bixibat product:

  • Used for temporary relief of minor musculoskeletal pain 1
  • Applied topically or taken orally depending on formulation 1
  • Indicated for arthritis-related pain, backache, strains, sprains, muscle soreness and stiffness 1

Common Pitfall

Do not confuse bixibat with linaclotide (Linzess). These are entirely separate medications with different indications, mechanisms, and routes of administration. 1, 2
