Morphine is actually a phenanthrene opioid receptor agonist – its primary effect is binding to and activating the μ-opioid receptor (MOR) during the central anxious method. Its intrinsic exercise in the MOR is heavily depending on the assay and tissue becoming analyzed; in a few predicaments This is a full agonist when in others it may be a partial agonist or even antagonist.[sixty nine] In scientific settings, morphine exerts its principal pharmacological effect about the central anxious technique and gastrointestinal tract. Its primary actions of therapeutic benefit are analgesia and sedation.
