  • Subcutaneous
  • 500–1000 mcg/day
  • ~95% (near-complete absorption)
  • 10–14 days
  • Moderate (requires reconstitution, daily injection)
  • Severe mucosal inflammation, patients who failed oral therapy
  • Best for inflammation-driven IBS-D with documented gut inflammation (elevated calprotectin, endoscopic findings). Delivers systemic exposure and faster symptom relief
  • Oral (enteric-coated)
  • 2000–4000 mcg/day
  • 15–25% (first-pass metabolism reduces absorption)
  • 3–4 weeks
  • Low (capsule form, no preparation)
  • Mild-to-moderate IBS symptoms, localized gut inflammation
  • Preferred for patients seeking convenience and those with primarily intestinal symptoms. Lower bioavailability offset by direct gut exposure
  • Oral (uncoated)
  • Not recommended
  • <10% (stomach acid degrades peptide)
  • Variable/unreliable
  • Low
  • None
  • Avoid. Uncoated oral KPV loses 80–90% potency before reaching the intestine; enteric coating is non-negotiable for oral efficacy
