Expert review of neurotherapeutics

Primary headache disorders are often accompanied by neck pain or other symptoms referable to neck muscles. Therefore, physical therapy and other physical treatments are commonly prescribed for headache management. A medical literature review was completed in order to gather information regarding the efficacy of selected physical modalities in the treatment of primary and cervicogenic headache disorders. ⋯ In the absence of clear evidence regarding their role in treatment, physicians and patients are advised to make cautious and individualized judgments about the utility of physical treatments for headache management. In most cases, the use of physical modalities should complement rather than replace better validated forms of therapy. The evidence base to determine the safety and efficacy of physical treatments in the management of headache disorders would be substantially improved by using standard scientific rigor in the development and conduct of future clinical studies.

The transdermal matrix patch formulation of buprenorphine has been shown to be effective in managing moderate-to-severe cancer pain and severe pain unresponsive to nonopioid analgesics. Clinical trials have revealed that it is possible to switch from weak opioids or low doses of step III opioids to transdermal buprenorphine without any problems. With buprenorphine patches, the sublingual buprenorphine intake was dose-dependently reduced and was superior to placebo in this respect. ⋯ Postmarketing surveillance studies have shown that transdermal buprenorphine is also effective in the management of nociceptive and neuropathic pain, which some studies have shown to be relatively insensitive to mu-opioid analgesics, such as morphine. Transdermal buprenorphine was well tolerated. Most adverse events were either local reactions to the patch that generally subsided within 24 h or systemic events typical of treatment with opioid analgesics, such as nausea, vomiting and constipation.
