Naltrexone and Phenibut Interaction
Naltrexone and Phenibut have an interaction requiring monitoring for interaction with 90% confidence. Both compounds affect neurological signaling pathways. Phenibut acts on GABA-B receptors while naltrexone modulates the opioid system. While there is no direct pharmacological antagonism, both substances influence mood and reward circuitry. Monitor for unexpected changes in mood, sedation, or tolerance patterns when used concurrently. These compounds primarily affect different organ systems.
Compound Profiles
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.

GABA-B Agonist | Anxiolytic & Sleep Aid
Phenibut acts primarily as an agonist at GABA-B receptors, the same receptor target as baclofen (to which it is structurally related). GABA-B receptor activation inhibits neuronal excitability by opening potassium channels and reducing calcium influx at presynaptic terminals, leading to decreased neurotransmitter release and a net inhibitory effect on the central nervous system.
