Resumo
Samidorphan is an opioid antagonist that blocks butorphanol's analgesic effect. In opioid-dependent patients it may precipitate acute withdrawal.
O que esta interação significa em palavras simples
Butorphanol and Olanzapine / samidorphan are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Por que acontece
Samidorphan antagonizes opioid receptors, opposing the effect of butorphanol.
O que fazer
Avoid the combination; follow the labeled opioid-free interval (7 days for short-acting, 14 days for long-acting opioids) before starting. Use non-opioid analgesics during treatment.
