Samidorphan blocks opioid receptors, reducing codeine analgesia and potentially precipitating withdrawal in dependent patients. Higher opioid doses to override the blockade risk overdose.
O que esta interação significa em palavras simples
Codeine 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 is a mu-opioid receptor antagonist that opposes the effects of opioid agonists.
O que fazer
