विवरण
Pregabalin combined with oxycodone produces synergistic respiratory and CNS depression, substantially elevating overdose risk.
तंत्र
Pregabalin modulates presynaptic calcium influx and GABA-ergic tone; oxycodone activates mu-opioid receptors — combined, they produce supra-additive respiratory depression.
नैदानिक महत्व
Gabapentinoid + opioid combinations are implicated in a growing proportion of overdose deaths in multiple countries.
प्रबंधन
