It was demonstrated that most of the asthmatics Muslim in our regions did not consider asthma to be a problem to Ramadan, and they pass in fasting by arranging their treatment as use the controller inhaler on Iftar and Sohoor time & stop taking the reliever inhaler in the day time. the Aim is to study the effect of Ramadan fasting on the clinical, spirometric figures of patients with stable asthma with treatment modification . Methods: A prospective cohort study was performed before, during and after Ramadan fasting on well-controlled asthmatic patients as they were classified according to the treatment types as: group 1: on inhaled budesonide + formoterol fixed single device (symbicort, Astra Zeneca, sewed) + on need short acting B adrenergic agonist. group 2 : short acting B adrenergic agonist on needed alone group 3: interleukins antagonists tablets Once daily (10 mg montelukast Na tablet) + short acting B adrenergic
agonist on needed. Results found that fasting seen to have detrimental effects on fasting in hot weather as FEV1, FEF in 50% and asthma control test score show statistically significant differences before & after fasting but patient on inhaled symbicort with treatment modification show better outcome.
