[Pain therapy].
NEW OPIOID ANALGESICS: Progress in pain reliet has recently been achieved with the introduction of new opioid analgesics such as tramadol and the pediatric preparation of codeine phosphate as well as powerful long-release opioids which can be administered per os, or percutaneously for transdermal fentanyl. CO-ANALGESICS: Other drugs, mainly antidepressants and anti-convulsants, can be usefully combined with analgesics. New serotonin uptake inhibitors and anticonvulsants (gabapentin and lamotrigin) have the advantage of better tolerance. None of these drugs has marketing approval in France for their pain relieving effects. The same is true for clonidine and neostigmine which, after spinal infusion, potentialize opioids and for ketamine which can relieve neuropathy pain by dissociative anesthesia. NEW ANTI-MIGRAINE DRUGS: New drugs have been developed for specific types of pain such as migraine. The new "triptans" are tolerated better than sumatriptan and is reimbursed by the national social security. REFRACTORY NEUROPATHY PAIN: Indications for electrical stimulation techniques conducted in a neurosurgery unit have been identified. Stimulators may be implanted in spinal or supra-spinal localizations. REGULATORY ASPECTS: New legislation has reorganized health care for pain relief in France. The new texts take into consideration personnel training, the health care network and progress in therapeutics.
