Question 1

what do beta 2 agonists do?

Answer 1

bind to receptors in the lungs, MIMIC ADRENALINE (sympathetic NS) = BRONCHODILATION to open up the airways and help with breathing

SABA= short acting beta 2 agonists- SALBUTAMOL
LABA= long acting- 

SIDE EFFECTS: increased HR and BP, sweating, shaking, anxiety

Question 2

anticholinergic/ muscarinic

block muscarinic acetylcholine receptors, results in decreased contractility of smooth muscle in the lungs (BRONCHODILATION) and reduction of mucus secretions therefore opening the airways

anticholinergic = PIUM

SIDE EFFECTS; dry mouth, pupil dilation,
slower onset- 4-6 weeks for effect

potent anti-inflammatory drug, decreased airway inflammation + reactivity by reducing inflammatory mediator. inhibiting the response of inflammatory cells.
