Question 4

Which prescribing principle is most critical when initiating new medications in a 78-year-old patient with multiple comorbidities and polypharmacy in New Zealand?

Accepted Answer

Apply 'start low, go slow' and conduct regular medication reviews to minimise polypharmacy risk

The 'start low, go slow' principle in elderly prescribing accounts for altered pharmacokinetics (reduced renal and hepatic clearance, increased receptor sensitivity) and polypharmacy risk, reducing adverse drug events.
