- leukotriene receptor antagonists
what are examples of bronchodilators?
- beta2 agonists
- anticholinergic
what is an example of an anti-inflammatory drug?
corticosteroid
what drug can improve gas exchange?
OXYGEN
how are inhaled drugs delivered?
- metered dose inhaler (MDI)
- spinhaler
- turbohaler
what can aid in inhaled drug delivery?
- nebulisers
- spacers
what is a nebuliser?
adevice that can deliver high doses of medicine quickly and easily. It works by changing liquid medicine into a fine mist.
what are examples of short-acting B2 agonists?
- salbutamol

what is an example of a long-acting B2 agonist?
- salmeterol
what drug is found in the green inhaler & why is it used?
- salmeterol
- used to prevent an asthma attack
