(a) 20 mg
(b) 10 mg
(c) 30 mg
(d) 40 mg
(e) 60 mg
Breakthrough dose is typically 10 mg oral morphine IR every 2–4 hours as needed. If the patient requires >2 breakthrough doses/day, their regular MST dose should be increased.
b
If the patient requires >2 breakthrough doses/day, their regular MST dose should be increased.
Why Not Higher?
30–60 mg (options c-e) would risk overdose (excessive sedation/respiratory depression).
20 mg (option a) is the calculated dose before adjusting for bioavailability.
