A total of 720 cancer patients receiving strong opioid analgesics from 35 institutions were enrolled, among whom 619 subjects were eligible. Prophylactic laxatives were medicated in 456 patients (74%), while antiemetics (mostly dopamine D2 blockers) were prescribed for prevention of nausea and vomiting in 435 subjects (70%). The incidence of constipation was significantly lower in patients receiving laxatives than in those without prophylactic medication (34% versus 55%, odds ratio [OR] 0.43, 95% confidence intervals [CI] 0.30-0.62, P<0.001), whereas nausea and vomiting occurred regardless of prophylactic treatment. Among laxatives, magnesium oxide (>=1,000 mg/day) was the only agent reducing the risk of constipation. Meta-analysis of OR determined in 14 institutions reporting >=16 patients indicated that overall OR for constipation was 0.47 (95% CI 0.23-0.96, P=0.04) in favor of prophylactic treatment, whereas administration of antiemetics was not a significant risk reducing the incidence of nausea and vomiting.
Therefore, it is evident that prophylactic laxatives including magnesium oxide (>=1,000 mg/day) reduces the incidence of constipation in patients receiving strong opioid analgesics. However, no evidence for prophylactic effect of antiemetics (dopamine D2 blocker) against opioid-induced nausea and vomiting was obtained. [Clinical Journal of Pain, in press]
