Unrelated eg MI
List the most appropriate drugs to treat the types of pain listed:
- Bone pain

- Paracetamol - 1g qds
- NSAIDS - 400mg qds - WEAK OPIOD
- Co-codamol: 8/500, 15/500, 30/500 qds

- *Morphine 10mg/5ml, 100mg/5ml
- *Diamorphine
- Oxycodone
- Fenatyl, Buprenorphine (patches)
- Methadone (last resort)
What are used as adjuvants to managing pain through the analgesic ladder?
Pharmacological: Neuropathic pain agents Steroids Buscupan Benzodiazepines
Non-pharmalogical: Massage Acupuncture Heat therapy TENS
Opiate prescribing is a big part of palliative care and hospital medicine.
- What is the 1st line strong opiate of choice?
- What strength does it come in?
- What units should you always prescribe this drug in?
- MORPHINE
- 10mg/5ml or 100mg/5ml (some brands 5mg/5ml)
- ALWAYS PRESCRIBE IN Mg
A 67 y/o lady in a hospice Is in her terminal days and requires morphine prescribed for her pain management. She has a history of a stroke but a safe swallow.
Describe the standard morphine regime she will need,
- 12hrly = long-acting - modified release for regular pain relief (oral).
- MST tablets
- Zomroph capsules
Dose: Start 20mg/5ml bd MST (converstion of co-codamol OR base on prn use)
- 2-4hrly = short-acting - for break-though pain
- Oromorph liquid (syringe)
- Sevredol tablets
Dose: 1/6 of long-acting total daily dose
A 78 y/o man with end-stage heart failure is on prn morphine 7mg. He is on 20 mg MST bd.
He is using his prn dose 8 times a day every 2 hours.
At what point do you review the prn dose and change the long-acting dose to provide better pain relief?
When the prn dose exceeds the total daily dose of MST
If you want to increase the MST dose then how much do you increase it by?
30-50% of current MST dose
What is the converson of oral prn dose morphine to sc morphine?
sc morphine = 1/2 X prn dose
There is no max dose for opiates. However, you can write the max dose as 6 X prn.
In which cases should the morphine dose be reduced?
Poor renal function
Elderly (delirium)
When is oral morphine contraindicated?
What is an alternative drug route?
Unsafe swallow
Patches - fentanyl, buprenorphine
Opiate SE are adverse effects but predictable.
What are the common SE of opiates?
Constipation- prescribe laxative (senna)
N/V - prescribe anti-emetic (1/3, goes in ~3days)
Drowsiness (goes in ~3 days, no driving)
Dry mouth
Opiate toxicity is when too much of the drug is given (reduced renal function, rug error, interactions, weight changes, narrow TI)
What are the signs of toxicity, in order?
Delirium, sedation Vivid dreams Pin-point pupils (get smaller as get older) Hallucinations - esp visual Myoclonus - jerky movements Respiratory depression - uncommon
What is the treatment for respiratory depression?
Naloxone
for any opiate toxicity - blocks & reverses effects of it
A 80 y/o lady with lung cancer and brain mets has chronic N/V from constipation and raised ICP.
If you didn’t know the cause of the N/V then how would you manage it?
