The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone.

Drug Interaction: Moderate

Concomitant use of oxycodone and fluoxetine can increase oxycodone plasma concentrations, potentially leading to enhanced opioid effects such as respiratory depression, sedation, and constipation. Conversely, fluoxetine may reduce the analgesic efficacy of oxycodone.

Mechanism: Fluoxetine is a potent inhibitor of CYP2D6, the enzyme responsible for converting oxycodone to its active metabolite oxymorphone. This inhibition leads to increased oxycodone levels and decreased oxymorphone levels, altering the overall opioid effect.
