What should be done 4th line if asthma is still not controlled?
Check FeNO and blood eosinophil count and if raised, refers o specialist asthma service
What to do 4th line if FeNO or blood eosinophil are not raised?
Moderate-dose MART with Addition of leukotriene receptor antagonist like montelukuast tablet every night
Long acting muscarinic agonist like tiotropium
What are the signs of poorly controlled asthma?

Maintenance therapy in very poorly controlled asthma unresponsive to add-on therapies
What is the next step for asthma not controlled by moderate dose MART?
Moderate dose MART includes LABA and moderate dose ICS.
Addition of LAMA should be done.

Bronchodilator reversibility testing which is an objective test recommended by NICE, if patient symptoms are not in severe exacerbationn
