Morphine for the symptomatic reduction of chronic breathlessness: the case for controlled release.
PURPOSE OF REVIEW
Clinicians who seek to reduce the symptomatic burden of chronic breathlessness by initiating regular low-dose morphine has the choice of immediate or sustained-release formulations - which will be better for this often frail population, and which has the more robust evidence to inform its prescription? Both formulations can be used.


RECENT FINDINGS
For chronic breathlessness, three factors consistently favour the use of regular, low-dose, sustained-release morphine over immediate-release formulations: SUMMARY: As the evidence base expands for the symptomatic reduction of chronic breathlessness, pharmacological interventions will play a part. Using the best available evidence underpins patient-centred approaches that seek to predictably maximize the net effect.As such, the weight of evidence in patient-centred clinical care favours the use of regular, low-dose sustained-release morphine for the symptomatic reduction of chronic breathlessness.
