Abstrakt: The article presents a study that determines the effects of parachlorophenylalanine (PCPA) on the sleep of a methadone addict. PCPA is a trytophan hydroxylase inhibitor which causes a major reduction in brain serotonin synthesis and levels, and slightly effects the brain norepinephrine metabolism. Researchers studied the effects of PCPA administration on the sleep of a 24-year-old male heroin addict who had been stabilized by methadone. They concluded that a significant increase in the delta wave sleep which coincides with urinary 5-hydroxyindoleacetic acid values leads them to speculate that there is a critical level of serotonin for optimal sleep and that levels of serotonin result to a decrease in delta sleep.
