Allergic rhinitis (AR) is an atopic disease characterized by symptoms such as sneezing, nasal congestion, clear rhinorrhea, and nasal pruritus. This study investigates the efficacy of a combination therapy using Fexofenadine Hydrochloride 120 mg and Montelukast Sodium 10 mg in managing AR. Leveraging an omnichannel marketing campaign on the Hidoc Dr platform, the study targeted healthcare professionals through digital channels like mobile apps, websites, emails, SMS, and tele-calling services. The campaign aimed to establish this combination therapy as a preferred choice among physicians. The results revealed significant engagement, with 166,606 healthcare professionals reached, 2,884,308 impressions, and 462,546 clicks. The campaign demonstrated a 16% click-through rate and generated 105 high-quality leads, confirming the increased preference and usage of the combination therapy for AR treatment.
