5
Q

What is a Opioid Rotation?

A
  • switch from one opioid to another

- aim is to provide a better balance analgesia and side effects

6
Q

What are the considerations before opioid conversions?

A
  • calculate the 24hrly requirements
  • convert back to oral morphine
  • then convert to alternative opioid
  • ensure adequate breakthrough
  • consider a dose reduction
7
Q

Describe Fentanyl patches

A
  • not any more effective as an analgesic than morphine
  • mu receptor agonist
  • 50-100x more potent than morphine
  • constant drug delivery for 72 hrs

Indication

  • When oral route is not available
8
Q

9
Q

What is Oxycodone?

A
  • 1.5-2x more potent than morphine orally
  • Available as quick and slow release formulations
  • K-opioid receptor agonist
  • titratable
10
Q

What is Oxycodone?

A
  • mixed pharmacology (NMDA and opioid activity)
  • variably long half life and potential for accumulation
  • useful when there is a complex element of neuropathic pain
  • available as tabs, liquid injection and suppository
11

12
Q

What are Bone Targeted Agents (BTA) for bone pain?

A

Biphosphonates

  • have been shown to reduce the incidence of skeletal complications
  • inhibit osteoclast activity
  • Consider Strontium Ranelate
    : radioactive isotopes
  • Denosumab
13

    : usually need at least 50mg
  • limited by side effects
14
Q

How is Anticonvulsants used in Palliative care europathic pain?

A
  • Activates pain suppression pathways
  • Sodium Valproate
    : 200-1000mg daily
    : 4~5 days to steady state
    : no clinical trials
  • Carbamazepine
    : common adverse effects
    : drug interactions
15
