Morphine abstinence and serotonin supersensitivity in man: analogies with the mechanism of migraine?

abstract：:In a double-blind, balanced crossover study, eight healthy male volunteers ingested either DL-308 (10 mg), DL-308 (20 mg), oxazepam (30 mg) or placebo. Subjective estimates of coordination and anxiety, objective performance measurements and cardiovascular measurements were taken at 1, 3, 5 and 8 h after ingestion. DL-...
