This study aims to compare the effectiveness and safety of two commonly used antihistamines, bilastine 20 mg and levocetirizine 5 mg, in patients diagnosed with chronic urticaria. Chronic urticaria is a skin condition characterized by recurrent itchy wheals that significantly affect quality of life.
Eligible participants will be randomly assigned to receive either bilastine or levocetirizine for a defined treatment period. The severity of symptoms, improvement in itching and wheals, and any adverse effects will be assessed during follow-up visits.
The results of this study will help determine which treatment provides better symptom control with fewer side effects in patients with chronic urticaria.
