Abstract

Background: Rhinitis is inflammation of nasal mucosa which characteristically presents as running nose, blocked nose, itching on nose or sneezing. Allergic rhinitis is more common than non-allergic rhinitis. Anti-histamines are the mainstay of SAR treatment. Desloratadine, rupatadine and ketotifen are the commonly prescribed anti histamines in our region. In this study, we have compared efficacy and tolerability of desloratadine, rupatadine and ketotifen in SAR.
Patients and Methods: This was a prospective, randomized, three arm, open label comparative study of desloratadine, rupatadine and ketotifen in SAR, conducted at Department of ENT, Kempegowda Institute of Medical Sciences, Bangalore; between January 2014 and December 2014. Patients’ severity of SAR symptoms were assessed by TNSS, QoL was measured using Medical Outcomes Study questionnaire (SF-12). SF-12 was administered at the start of study and then at the end of study. Adverse effects were monitored during clinical examination at each visit. Study subjects were systemically randomized into three groups – desloratadine (DES), rupatadine (RUP) and ketotifen (KET). Based on the assigned group; desloratadine was given orally in dose of 10mg OD, rupatadine orally 10 mg OD and ketotifen orally 1mg BD. All medications were given for 4 weeks. Follow up was done for all patients every week during treatment period of 4 weeks. The primary outcome measure was change in mean TNSS from baseline; secondary outcome measures were changes in the individual nasal symptom scores, change in the quality of life and tolerability to the study medications.
Results: Total 150 patients were recruited for this study, divided into 3 groups. DES and RUP were equally effective but significantly better than KET in improving rhinorrhea, nasal congestion, TNSS and AEC. (p=0.05). All the drugs were equally effective with no statistically significant intergroup difference in improving sneezing, nasal itching and QoL. RUP appeared to have better tolerability as the total number of adverse events were marginally less.
Conclusion: DES and RUP are comparatively more effective and faster acting than KET. All the study medications were well tolerated with few mild, self-limiting, transient adverse events requiring no intervention.
