Zecoryl Tablet is a combination medication containing Chlorpheniramine Maleate (2 mg), Paracetamol (500 mg), and Phenylephrine (5 mg), formulated for the symptomatic relief of common cold, allergic rhinitis, and related upper respiratory tract conditions. Chlorpheniramine Maleate, an antihistamine, alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. Paracetamol acts as an analgesic and antipyretic, effectively reducing fever and relieving mild to moderate pain associated with cold and flu. Phenylephrine, a selective alpha-1 adrenergic receptor agonist, serves as a decongestant by constricting nasal blood vessels, thereby reducing nasal congestion and improving breathing. The combined action of these agents provides comprehensive relief from multiple symptoms, enhancing patient comfort. Zecoryl Tablet is indicated for adults and children over 12 years of age and should be used according to the prescribed dosage to minimize potential side effects such as drowsiness, dry mouth, or increased blood pressure. It is contraindicated in patients with hypersensitivity to any component, severe hypertension, or certain cardiovascular conditions. Caution is advised when administered with other sympathomimetic or CNS depressant drugs. Consultation with a healthcare professional is recommended prior to use, especially in patients with underlying medical conditions.
