Randomized Controlled Trial Comparative Study Clinical Trial
Analgesic efficacy of a hydrocodone with ibuprofen combination compared with ibuprofen alone for the treatment of acute postoperative pain.
Hydrocodone is a semisynthetic opioid with analgesic and antitussive properties qualitatively similar to other opioid agonists. Ibuprofen is a nonsteroidal antiinflammatory agent with analgesic and antipyretic activity and is an effective, primarily peripheral-acting antiinflammatory analgesic. The objective of this clinical trial was to determine the additive analgesic effect of the combination of 15 mg hydrocodone bitartrate with 400 mg ibuprofen, relative to 400 mg ibuprofen alone and placebo, in the treatment of postoperative pain. ⋯ The combination of hydrocodone with ibuprofen was significantly superior to ibuprofen for all hourly analgesic evaluations, weighted sum of pain intensity differences (SPID), total pain relief (TOTPAR), and global rating of study medication. No patients in the hydrocodone with ibuprofen group required analgesic remedication during the 6-hour study period, compared with 25% and 82% in the ibuprofen and placebo groups, respectively. The analgesic superiority of 15 mg hydrocodone bitartrate combined with 400 mg ibuprofen compared with 400 mg ibuprofen alone was demonstrated across many efficacy variables.

Randomized Controlled Trial Clinical Trial
Tolerance and efficacy of polyethylene glycol 3350/electrolyte solution versus lactulose in relieving opiate induced constipation: a double-blinded placebo-controlled trial.
Chronicity and high therapeutic cost prompted this study to determine a cost-effective and efficacious regimen in treating narcotic-induced constipation. The efficacy of lactulose was compared with polyethylene glycol 3350/electrolyte solution for relief of methadone-induced constipation. This was a randomized, triple cross-over after control run-in (no treatment) study conducted at a methadone maintenance program in Baltimore, Maryland in 57 patients who are affected by opiate-induced constipation. ⋯ There were no significant differences in reducing hard stool formation in either experimental group, but both were better than having nothing or just the placebo. Polyethylene glycol/electrolyte solution resulted in the loosest (diarrheal) stool. It is also likely that polyethylene glycol/electrolyte solution is the most cost effective.
