Abstract
The results of treating acute or chronic pain with Distalgesic were compared in a double-blind fashion with the new partial antagonist analgesic meptazinol. Both drugs had similar analgesic time effect profiles and both were acceptable to doctor and patients. However the side-effect profile was better for meptazinol than Distalgesic and so meptazinol may be a useful alternative to Distalgesic in the treatment of everyday pain states.
