MK-677 and Naltrexone Interaction

Avoid
Mechanism-based 64% confidence

MK-677 and Naltrexone have a potentially harmful interaction with 64% confidence. Both MK-677 and Naltrexone carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. These compounds primarily affect different organ systems.

Compound Profiles

MK-677

Ghrelin Receptor Agonist | Oral Growth Hormone Secretagogue

Selectively binds GHS-R1a receptors in hypothalamus and pituitary, triggering pulsatile growth hormone release while maintaining natural circadian patterns..

Naltrexone

Opioid Antagonist | Low-Dose Anti-Inflammatory & Immune Modulation

At low doses (1-4.5 mg), naltrexone produces a brief nocturnal blockade of opioid receptors that lasts approximately 4-6 hours.

Half-life: ~4 hours Typical dose: 1.5-4.5 mg/day (LDN) immune, longevity
