ReviewKetamine as an analgesic: parenteral, oral, rectal, subcutaneous, transdermal and intranasal administration.
Ketamine is a parenteral anesthetic agent that provides analgesic activity at sub-anesthetic doses. It is an N-methyl-D-aspartate (NMDA) receptor antagonist with opioid receptor activity. Controlled studies and case reports on ketamine demonstrate efficacy in neuropathic and nociceptive pain. ⋯ Use of this drug by the oral, intranasal, transdermal, rectal, and subcutaneous routes has been reported with analgesic efficacy in treating nociceptive and neuropathic pain. Ketamine also has been reported to produce opioid dose sparing and good patient acceptance. A transdermal formulation is currently under patent review in Brazil and an intranasal formulation is currently undergoing phase I/II clinical trials.

Methadone hydrochloride is a mu-opioid agonist that has been used for the treatment of pain and for the management and maintenance of opioid withdrawal for over 50 years. Several characteristics make methadone a useful drug. However, these same characteristics and wide interpatient variability can make methadone difficult to use safely. ⋯ Published studies demonstrate methadone's efficacy in pain management and in opioid withdrawal. However, interpatient variability in pharmacokinetic variables of methadone produces difficulties in developing guidelines for methadone use. Clinicians should not be deterred from use of this drug which has been shown to benefit patients in both pain management and methadone maintenance, but an individualized patient approach must be taken to use methadone safely.

Comparative StudyManagement of cancer pain evidence report technology assessment: number 35--management of cancer pain summary.
Under its Evidence-Based Practice Program, the Agency for Healthcare Research and Quality (AHRQ) is developing scientific information for other agencies and organizations on which to base clinical guidelines, performance measures, and other quality improvement tools. Contractor institutions review all relevant scientific literature on assigned clinical care topics and produce evidence reports and technology assessments, conduct research on methodologies and the effectiveness of their implementation, and participate in technical assistance activities.

The Cochrane Collaboration Pain, Palliative Care and Supportive Care Collaborative Review Group.
The Pain, Palliative and Supportive care group is one of 50 collaborative review groups that make up the Cochrane Collaboration, an international organization with the task of preparing, maintaining and disseminating systematic reviews of the effects of healthcare. Cochrane reviews are published cumulatively four times a year on the Cochrane library (CD-ROM and Web-based), along with other useful material such as a register of some 300,000 randomized controlled trials. The group has identified some 20,000 randomized trials in pain and 1,200 in palliative care. ⋯ The Pain, Palliative and Supportive care group is an informal international team involving some 100 people from some 18 countries. The group has published 26 protocols and 17 full reviews with a further 50 reviews in progress. The task is huge and there is scope for further volunteers to help with the various tasks of writing reviews, peer reviewing and literature searching.

Case ReportsPain relief from baclofen analgesia in a neuropathic pain patient who failed opioid and pharmacotherapy: case report.
A case report and discussion of a 64-year-old white female who presented with uncontrolled pain in several body areas despite massive oral controlled release morphine use is presented. Her pain was not associated with much spasticity. This patient responded remarkably to intrathecal baclofen even after the opioid was tapered and discontinued. The potential usefulness of baclofen in seemingly opioid-resistant chronic pain is discussed.
