Reasonable naloxone administration in cancer pain management / 中国肿瘤临床

ABSTRACT

Naloxone is a synthetic pan-opioid receptor competitive antagonist of the opioid receptors inside and outside the cen-tral nervous system. After systemic administration, it reverses almost all opioid effects. Systemically administered naloxone is used to reverse the life-threatening opioid toxicity. A number of studies have analyzed the importance of oral naloxone as a peripheral opioid an-tagonist in cancer patients. Naloxone has shown satisfactory efficacy for opioid-induced constipation (OIC). Ultra-low dose of naloxone has been reported to enhance the anti-nociceptive effect of morphine and reduce morphine consumption. We summarize the results from current studies of naloxone administration in cancer pain management.
