Resumo
Alvimopan is a peripherally acting mu-opioid antagonist, and patients who have taken opioids for more than a week before starting it are more sensitive to its effects. They may develop abdominal pain, nausea, vomiting and diarrhea. Short-term opioid exposure, as in the postoperative setting, is the intended use.
O que esta interação significa em palavras simples
Alvimopan and Morphine 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
Competitive antagonism at peripheral gastrointestinal mu-opioid receptors in opioid-tolerant patients.
O que fazer
Do not give alvimopan to patients who have received therapeutic opioid doses for more than 7 consecutive days before it. Limit use to short-term perioperative opioid exposure.
