2) Neuropathic (from nerve injury)
- Peripheral
- Central

- Changing characteristics of pain
- Post-analgesia
~ Evaluation of effectiveness

- Only use injections if px cannot take orally or drug is not able to be absorbed via GIT
2) By the clock
- Most oral analgesics only last <4 hours
~ Tf must be prescribed every 4 hrs to achieve effects
3) By the ladder
- Following WHO’s pain ladder
- Dose titrated until:
~ Max recommended dose is reached
~ Pain is relieved or
~ Px has serious side effects
What is WHO’s pain ladder?
Step 1: Non-opioids
- NSAIDs, Paracetamol
- +- adjuvant analgesics
Step 2: Weak opioids
- TRAMADOL
- CODEINE
Step 3: Strong opioids
- Immediate releade
~ MORPHINE solution
~ Oxycodone
~ Methadone
- Controlled release
~ MORPHINE SULPHATE tab
~ Transdermal FENTANYL
~ Oxycontine
What are adjuvant analgesics?
- Treats neuropathic pain
- Can be added to any of the steps in the WHO Pain Ladder
- Tricyclic antidepressants
- Anticonvulsants
~ Gabapentin
~ Pregabalin - Topical
~ Lignocaine - Steroids
~ Dexamethasone
Why is it important to have opioid rotation?
- Resistance
- Side effects
- Morphine is available orally (tf least invasive)
- Fentanyl is not effective for acute pain
- Fentanyl takes longer to work (8-12 hours)
Is there a maximum dose for morphine and fentanyl in a palliative situation?
- No max dose
When is morphine used?
- Moderate to severe pain
- Dyspnea
