Zuka Oral Drops contain Chlorpheniramine Maleate (2mg/ml) and Phenylephrine (2.5mg/ml), formulated to provide effective relief from symptoms associated with allergic conditions and nasal congestion. Chlorpheniramine Maleate is an antihistamine that works by blocking H1 histamine receptors, thereby reducing allergic manifestations such as sneezing, itching, watery eyes, and runny nose. Phenylephrine is a selective alpha-1 adrenergic receptor agonist that acts as a nasal decongestant by constricting blood vessels in the nasal mucosa, leading to decreased swelling and improved airflow. This combination makes Zuka Oral Drops suitable for managing symptoms of allergic rhinitis, common cold, and sinusitis. The oral drop formulation allows for easy administration and rapid onset of action. It is important to use this medication as directed by a healthcare professional, considering potential contraindications such as hypertension, cardiovascular diseases, and hyperthyroidism due to the vasoconstrictive effects of Phenylephrine. Caution is advised in patients taking monoamine oxidase inhibitors or other sympathomimetic drugs. Adverse effects may include drowsiness, dry mouth, dizziness, and increased blood pressure. Zuka Oral Drops should be stored in a cool, dry place, away from direct sunlight and out of reach of children.
