To compare the efficacy of levocetirizine with montelukast and levocetirizine alone in patients with persistent allergic rhinitis in our setup.

Patients with symptoms of AR attending ENT clinic were registered and divided into two groups based on drug given. Patients with odd numbers were included in group A receiving levocetirizine 5mg with montelukast 10mg once daily while patients with even numberswere included in group B receiving only levocetirizine 5mg once daily. Data was collected at visit 1 prior to medication, visit 2 one week after medication and visit 3 two weeks after medication. Medication history review, nasal symptom assessment and anterior rhinoscopy were done ateach visit. Patients were evaluated for rhinorrhea, sneezing, nasal itching and nasal obstruction on a scale. Total symptom complex score (TSCS) was calculated by adding scores of all four variables under study using proforma. Lower the score more effective will be the drug.

One hundred twenty four patients were included in study; 63 were male and 61 were female. TSCS was 9 -10 in 73.3% patients at visit 1 in levocetirizine + montelukast group that improved to 4-5 in 28.3% and 3- 4 in 65% patients at visit 2 and 3 respectively. Patients receiving levocetirizine alone had TSCS of 9 to 10 in 52.9% at visit 1 with an improvement to 3-4 in 9.4% and 49.1% at visit 2 and visit 3 respectively.

Levocetirizine with montelukast is superior to levocetirizine alone in controlling overall symptoms of AR.
