Research Status

Safety
& evidence

Adrenomedullin

Evidence Level

Moderate human trials (Phase 1-2)

FDA Status

Research compound

Safety Overview

Adrenomedullin safety in humans is poorly characterized, with clinical data limited to observational studies and small uncontrolled trials in cardiovascular patients. Animal studies demonstrate potent vasodilatory effects that could lower blood pressure dangerously, particularly in patients on antihypertensive medications. No human pharmacokinetic studies have established safe doses, and potential for hypotension, electrolyte disturbances, and off-target vasodilation effects exists. The peptide crosses the blood-brain barrier and affects central nervous system function in animal models, raising concerns about neurological effects at higher doses.

Contraindications

  • xSevere hypotension or shock states
  • xConcurrent use with certain vasopressor medications
  • xPregnancy and breastfeeding
  • xSevere kidney or liver dysfunction

Thymosin Beta-4

Evidence Level

Moderate human trials (Phase 1-2)

FDA Status

Research compound

Safety Overview

Thymosin Beta-4 is a naturally occurring peptide found in all cells and body fluids in the human body. Clinical trials have demonstrated excellent safety even at very high doses. IV studies showed doses up to 1260 mg were well tolerated with no serious adverse events.

Contraindications

  • xActive systemic infections
  • xSevere immunosuppression
  • xHypersensitivity to thymosin or any component
  • xPregnancy (insufficient safety data)
