Role of inhaler steroid
Increase sensitivity of adrenaline to bronchial smooth muscle = bronchodilation
Inhibit Ag-Ab reaction = suppression of inflammatory response
Inhibit of LT , PG, PAF synthesis = decrease bronchial hyper activity
Decrease capillary permeability = decrease bronchial oedema and congestion
Benefits of inhaler steroid
Directly acts in the site of action
Rapidly relief of bronchial asthma
Less dose requirement
Less a/e
More patient compliance
Disadvantage of inhaler salbutamol
Dryness of airway
Irritation if airway
Oropharyngeal candidiasis
Knowledge needed
Expensive
Roflumilast is
Selective phosphodiesterase -4 inhibitor
Indication of Roflumilast
Maintainence and treatment of severe COPD
Bronchial asthma
A/E
Diarrhoea
Nausea
Headache
Insomnia
Anxiety
Nervousness
Depression
Contraindications
Hypersensitive to Roflumilast
Moderate to severe liver impairment
Pregnancy
