Show answerHide answer
Answer: A · A stimulant laxative with a stool softener
Constipation affects nearly every patient on regular opioids, and tolerance to it does not develop, unlike tolerance to nausea and sedation. Opioids act on mu receptors in the gut wall to reduce peristalsis and secretions, so a regular stimulant laxative such as senna or bisacodyl, often with a softener, is started with the first dose. Nausea usually settles within a week, so an antiemetic is given only as needed. Kerala's community palliative care network makes oral morphine widely available for such patients.
- B: Opioid nausea is usually transient, so antiemetics are given when needed, not for the whole course.
- C: Naloxone would reverse the analgesia and is used only for opioid overdose.
- D: Morphine does not cause peptic ulceration, so a PPI is not routinely needed.
