Expert opinion on the prescription practice of antihistamines for the management of allergic rhinitis in Indian settings

Abstract

Several clinical studies corroborate the synergistic effects of montelukast in conjunction with antihistamine for reducing the symptoms and quality of life of AR patients. Some studies also highlighted a significant quantitative differences in the prescribing patterns of antihistamines across different countries. So, this study aimed to gather expert opinions on the management of allergic rhinitis (AR) using antihistamines alone or in various combinations in Indian settings.The cross-sectional, multiple-response, 23-item survey was primarily focused on current practices, clinical observations, and experiences related to AR and the utilization of oral histamines for disease management. The study involved otorhinolaryngologist from diverse settings in India.Out of 435 participants, 29% reported sneezing as the common AR symptoms. The majority (84.83%) favoured antihistamine and leukotriene receptor antagonist combinations for AR treatment. Specifically, 52% preferred levocetirizine, while 43% favoured fexofenadine. About 63% opted for polytherapy with oral antihistamines and anti-leukotrienes for AR management. Of these, 48% chose levocetirizine and montelukast for various AR symptoms. According to 60% of participants, fexofenadine + montelukast effectively improved nasal and eye symptoms. Around 64% preferred levocetirizine + montelukast for nighttime nasal symptoms, while 55% chose fexofenadine + montelukast for daytime nasal symptoms. Around 64% of the respondents favoured levocetirizine + montelukast for improving all AR symptoms, and 69% favoured antihistamine + montelukast for its cost-effectiveness.Experts recommend antihistamine and leukotriene receptor antagonist combinations for managing AR symptoms, with levocetirizine and fexofenadine being popular choices. Polytherapy with these combinations was favoured, especially for managing nighttime and daytime nasal symptoms.
