Description
Gabapentin significantly potentiates the CNS and respiratory depressant effects of morphine, increasing overdose risk.
Mécanisme
Gabapentin modulates alpha-2-delta subunits of voltage-gated calcium channels and amplifies opioid-mediated respiratory depression through synergistic inhibitory mechanisms.
Signification clinique
Clinical studies show that gabapentin co-administration with morphine significantly increases sedation and respiratory depression scores.
Prise en charge
If combination is needed for pain management, start with lowest doses and titrate cautiously; monitor closely for respiratory depression.
