How Deletus BL Syrup works

Deletus BL Syrup is a combination of three medicines: Dextromethorphan hydrochloride, bilastine, and phenylephrine. Dextromethorphan hydrochloride suppresses the cough reflex by acting on the brain's cough center. Bilastine blocks histamine receptors to reduce allergy symptoms like sneezing and runny nose. Phenylephrine narrows blood vessels in the nasal passages to relieve congestion and improve breathing. Together, these three components work together to relieve cough, allergy symptoms, and nasal congestion, providing comprehensive relief from cold symptoms.
