Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Treatment of painful diabetic neuropathy with topical capsaicin. A multicenter, double-blind, vehicle-controlled study. The Capsaicin Study Group.
A multicenter study was conducted to establish the efficacy of topical 0.075% capsaicin cream in relieving the pain associated with diabetic neuropathy. Capsaicin or vehicle cream was applied to painful areas four times per day for 8 weeks in patients randomly assigned to one of two groups. ⋯ With the exception of transient burning, sneezing, and coughing, capsaicin was well tolerated. Study results suggest that topical capsaicin cream is safe and effective in treating painful diabetic neuropathy.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialTreatment of arthritis with topical capsaicin: a double-blind trial.
The neuropeptide substance P has been implicated in the pathogenesis of inflammation and pain in arthritis. In this double-blind randomized study, 70 patients with osteoarthritis (OA) and 31 with rheumatoid arthritis (RA) received capsaicin (a substance P depletor) or placebo for four weeks. The patients were instructed to apply 0.025% capsaicin cream or its vehicle (placebo) to painful knees four times daily. ⋯ According to the global evaluations, 80% of the capsaicin-treated patients experienced a reduction in pain after two weeks of treatment. Transient burning was felt at the sites of drug application by 23 of the 52 capsaicin-treated patients; two patients withdrew from treatment because of this side effect. It is concluded that capsaicin cream is a safe and effective treatment for arthritis.

Randomized Controlled Trial Multicenter Study Clinical TrialCapsaicin: a therapeutic option for painful diabetic neuropathy.
Fifteen patients with diabetes mellitus who had painful diabetic neuropathy (PDN) were enrolled in a double-blind study to test the safety and efficacy of capsaicin 0.075% (Axsain, Genderm, Northbrook, IL). Twelve of the 15 patients completed the eight-week study. Nine of the 12 patients reported symptomatic relief; of these nine, five used the drug and four used the vehicle. ⋯ Capsaicin is potentially effective when burning pain is a major symptom of PDN. The side effects of capsaicin were limited and minimal. This agent should be considered by clinicians for treatment of PDN.

Multicenter clinical trial of ibuprofen and acetaminophen in the treatment of postoperative dental pain.
Pharmacological management of pain for acute and chronic conditions has been guided by a scientific understanding of peripheral and central acting mechanisms for the control of inflammation as well as pain. Oral surgery pain is a reliable model to reference the effectiveness of commonly used analgesics such as ibuprofen and acetaminophen. ⋯ After 6 hours, the degree of pain relief and tolerance was assessed. Ibuprofen has important implications for postoperative pain in clinical practice.

Comparison of repeat doses of intramuscular ketorolac tromethamine and morphine sulfate for analgesia after major surgery.
A multicenter, randomized, double-blind, parallel study in 542 patients with moderate or severe postoperative pain compared the analgesic efficacy and safety of intramuscular ketorolac 30 mg (324 patients), morphine 6 mg (110 patients), and morphine 12 mg (108 patients) administered as needed as often as every 2 hours for a maximum of 20 doses or 5 days. The efficacy of ketorolac 30 mg was comparable to that of morphine 12 mg on every efficacy measure (average pain intensity, average pain relief, mean overall medication rating, and percentage of patients withdrawing because of inadequate relief). Ketorolac was statistically superior to morphine 6 mg for average pain intensity and mean overall rating. Ketorolac-treated patients had fewer adverse events than those who received either morphine dose.
