Mechanism of action

DDO contains alkaloids from opium poppies, primarily morphine, which act as agonists at mu, delta, and kappa opioid receptors. This receptor activation reduces pain perception and decreases gastrointestinal motility. The deodorized formulation removes volatile compounds while retaining the active opioid alkaloids, making it suitable for oral administration in clinical settings.
