How Symproic (naldemedine) works
People who take opioid medications for pain commonly experience constipation as a side effect. This is because opioid receptors are found in the brain and the gut. Opioid medications ease pain by affecting the receptors in the brain, but they cause constipation when they affect the receptors in the gut.
Symproic (naldemedine) is a peripherally acting mu-opioid receptor antagonist (PAMORA). This means that it blocks opioid receptors in the gut only, but not in the brain. As a result, Symproic (naldemedine) relieves constipation from opioid medications, without affecting their pain-relieving actions.
