Efficacy and tolerability of a hydrocodone extended-release tablet formulated with abuse-deterrence technology for the treatment of moderate-to-severe chronic pain in patients with osteoarthritis or low back pain.

This double-blind, placebo-controlled study evaluated the efficacy and safety of hydrocodone extended release (ER) developed with abuse-deterrence technology to provide sustained pain relief and limit effects of alcohol and tablet manipulation on drug release. Eligible patients with chronic moderate-to-severe low back or osteoarthritis pain were titrated to an analgesic dose of hydrocodone ER (15-90 mg) and randomized to placebo or hydrocodone ER every 12 hours. The primary efficacy measure was change from baseline to week 12 in weekly average pain intensity (API; 0=no pain, 10=worst pain imaginable).

Randomized, double-blind, placebo-controlled clinical trial of loperamide plus simethicone versus loperamide alone and simethicone alone in the treatment of acute diarrhea with gas-related abdominal discomfort.

Objective: To compare efficacy and tolerability of a loperamide/simethicone (LOP/SIM) combination product with that of loperamide (LOP) alone, simethicone (SIM) alone, and placebo (PBO) for acute nonspecific diarrhea with gas-related abdominal discomfort.

Research Design And Methods: In this multicenter, double-blind, 48-h study, patients were randomly assigned to receive two tablets, each containing either LOP/SIM 2 mg/125 mg (n = 121), LOP 2 mg (n = 120), SIM 125 mg (n = 123), or PBO (n = 121), followed by one tablet after each unformed stool, up to four tablets in any 24-h period. The primary outcome measures were time to last unformed stool and time to complete relief of gas-related abdominal discomfort.

Low-dose cyclobenzaprine versus combination therapy with ibuprofen for acute neck or back pain with muscle spasm: a randomized trial.

Objective: This prospective, randomized, open-label, multicenter, community-based study was conducted to compare cyclobenzaprine 5 mg three times daily (TID) orally (CYC5) given for 7 days as monotherapy or in combination with ibuprofen 400 mg TID (CYC5/IBU400) or 800 mg TID (CYC5/IBU800) in adults with acute neck or back pain with muscle spasm.

Study Design: Eligible patients were 18-65 years old, had cervical or thoracolumbar pain and spasm for < or = 14 days, and, aside from the prescribed study medications, discontinued treatment with all analgesics, anti-inflammatory agents, and skeletal muscle relaxants during the study period. Randomization was 1:1:1 to the three treatment groups.
