Low-Dose Naltrexone

Pharmaceuticals

Mechanism

Transient opioid receptor blockade that may increase endogenous endorphin signaling and modulate immune tone in off-label protocols.

Contraindications

  • Concurrent opioid use
  • Use caution in active liver disease

Mechanism

Alternative electron carrier in the mitochondrial electron transport chain. Bypasses Complex I and III dysfunction by shuttling electrons directly to Complex IV (cytochrome c oxidase). Also inhibits tau aggregation, monoamine oxidase, and nitric oxide synthase. Hormetic — low doses are beneficial, high doses are toxic.

Contraindications

  • G6PD deficiency (hemolytic anemia)
  • Concurrent serotonergic medication
  • Renal impairment
  • Pregnancy
