Wikoryl 10 Tablet is a combination pharmaceutical formulation containing Chlorpheniramine Maleate (2mg), Paracetamol (500mg), and Phenylephrine (10mg), designed for the symptomatic relief of common cold, allergic rhinitis, and related upper respiratory tract conditions. Chlorpheniramine Maleate, an antihistamine, acts by blocking H1 histamine receptors, thereby alleviating symptoms such as sneezing, runny nose, and watery eyes associated with allergic responses. Paracetamol serves as an analgesic and antipyretic agent, effectively reducing fever and relieving mild to moderate pain including headaches and body aches commonly experienced during viral infections. Phenylephrine, a selective alpha-1 adrenergic receptor agonist, functions as a nasal decongestant by constricting blood vessels in the nasal mucosa, leading to decreased swelling and improved nasal airflow. The combined action of these active ingredients provides comprehensive symptomatic management of cold and allergy symptoms. Wikoryl 10 Tablet should be used as directed by a healthcare professional, with caution advised in patients with hypertension, cardiovascular diseases, or hypersensitivity to any component. It is contraindicated in individuals with severe liver impairment or concurrent use of monoamine oxidase inhibitors. Adherence to recommended dosage is essential to minimize adverse effects and ensure therapeutic efficacy.
