Intervention
Eligible patients were allocated randomly into group A and in group B in equal number using block randomisation. Group A was treated with azithromycin 500 mg three times every alternate day for 24 weeks and group B was treated with conventional therapy for asthma. The patients of either group were evaluated at baseline, during and at the end of 24 weeks. Records of exacerbation (moderate vs severe), number of exacerbations, symptomatic improvement and adverse events were monitored during the study period.
