Inhaled route (such as ICS) – Advantages:

-quick onset of action – get total dose, higher in situ drug conc than oral and parenteral routes – good

systemic absorption -> however systemic side effects

Considerations before changing Rx

– check compliance w/ existing therapies – inhaler technique – try to identify + eliminate trigger factors

-can’t check lung function as children haven’t fully developed yet!!

Compliance: can be checked through patient self-reporting, refill data, reliever : preventer use

-can be improved through reminders, routines, edu

Written asthma plan:

-self-management - wallet-sized card/paper sheet -> written

-used to recognise and respond to worsening asthma

-symptom-based or PEF reading-based (based on personal best) - individually tailored to the pattern of

asthma (Pt preferences considered)

-explained to the patient/carer

-review and update periodically
