Study Notes
Treatment of Opioid-Induced Constipation (OIC)
- Peripherally-acting mu-opioid receptor antagonists (PAMORAS) are used to treat OIC.
- PAMORAS work by blocking opioid receptors in the gut to reduce constipation.
- PAMORAS do not affect analgesia, which means they do not reduce the pain-relieving effects of opioids.
- PAMORAS are only effective when constipation is caused by the use of opioids.
Drug Dosing and Safety
- PAMORAS have specific dosing regimens.
- Patients taking PAMORAS must be monitored for side effects and safety.
- The safety and side effects of PAMORAS vary depending on the specific drug used.
