A

Canagliflozin

Pharmaceuticals

Mechanism

SGLT2 inhibitor originally developed for type 2 diabetes. Blocks glucose reabsorption in kidneys, creating a mild glucose deficit that activates AMPK and mimics caloric restriction. Extended lifespan in male mice in the ITP.

Contraindications

  • Type 1 diabetes (DKA risk)
  • Severe renal impairment (eGFR <30)
  • History of recurrent UTIs
B

Retatrutide

Pharmaceuticals

Mechanism

Triple incretin agonist (GIP/GLP-1/glucagon receptor). Combines appetite suppression and insulin sensitization of GLP-1 with the thermogenic and lipolytic effects of glucagon receptor activation. Produced the greatest weight loss of any anti-obesity agent in Phase 2 trials (~24% at 48 weeks).

Contraindications

  • Not FDA-approved
  • Presumed similar to GLP-1 class — MTC, pancreatitis, severe GI disease
