MORPHINE AND APOMORPHINE INHIBIT GASTROINTESTINAL TRANSIT (GIT) THROUGH TWO DIFFERENT MECHANISMS

Morphine was used as a remedy for the control of diarrhea centuries before it's sedative-analgesic effect was discovered. Although several mechanisms have been proposed for the morphine-induced inhibition of gastrointestinal transit (OIT), the exact mechanism has not yet been identified. On this basis the possible involvement of the dopaminergic system in morphine-induced inhibition of tra...
