Pethidine is a phenylpiperidine derivative opioid analgesic. It acts mainly as mu-receptor agonist. Like most, opioid analgesics, it mimics endogenous opioids by activating opioid receptors in the central and peripheral nervous system. It reduces the release of neurotransmitter substances and also reduces the activity of postsynaptic neurons in the spinal cord thus preventing transmission of pain impulse.
Increased pethidine metabolite levels with aciclovir, cimetidine, ritonavir. Reduced analgesic effects with phenytoin, barbiturates. Additive sedative and/or respiratory depressive effects with alcohol, barbiturates, benzodiazepines, phenothiazines, TCAs, other CNS depressants. Potentially Fatal: Increased risk of serotonin syndrome with MAOIs (not be given concurrently or within 14 days of their discontinuation), serotonin agonists, serotonin reuptake inhibitors, sibutramine, TCAs.
Pregnancy Category B, D if prolonged use/high doses at term.
