Wikoryl AF Syrup is a combination medication containing Chlorpheniramine Maleate (2mg/5ml) and Phenylephrine (5mg/5ml), formulated to provide symptomatic relief from allergic conditions and nasal congestion. Chlorpheniramine Maleate is an antihistamine that antagonizes H1 histamine receptors, effectively reducing symptoms such as sneezing, runny nose, itching, and watery eyes associated with allergic rhinitis and other hypersensitivity reactions. Phenylephrine is a selective alpha-1 adrenergic receptor agonist that acts as a decongestant by causing vasoconstriction of nasal mucosal blood vessels, thereby decreasing nasal swelling and congestion. Wikoryl AF Syrup is indicated for the management of allergic rhinitis, common cold, sinusitis, and other upper respiratory tract conditions presenting with nasal congestion and allergy symptoms. The syrup formulation allows for easy administration, especially in pediatric and adult patients who have difficulty swallowing tablets. Caution is advised in patients with hypertension, cardiovascular disease, hyperthyroidism, and glaucoma due to the vasoconstrictive properties of phenylephrine. Common adverse effects may include drowsiness, dry mouth, dizziness, and increased blood pressure. It is recommended to use this medication under medical supervision, adhering to prescribed dosages to minimize potential side effects and drug interactions.
