Things to look out for
When should you stop

Starting opioid treatment
Caution in?
Offer patients regular oral release morphine, with 1/6 total dose for breakthrough pain.
Oral release is preferable to transdermal patches.
Laxatives should be prescribed for all starting strong opioids
Careful in CKD patients (use alfentanil, buprenorphine and fentanyl)
If trough levels are raised?
Increase interval between doses
Assumes peak dose is not too high (then need to reduce dose size)
If peak levels are raised?
Reduce dose drug
Assumes trough dose is not too high (then need to increase dose interval)
Steps of stable angina mangement
