Zukamin Cold Oral Drops contain Chlorpheniramine Maleate (2mg/ml) and Phenylephrine (2.5mg/ml), formulated for the symptomatic relief of common cold and allergic conditions. Chlorpheniramine Maleate is an antihistamine that effectively reduces allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. Phenylephrine acts as a selective alpha-1 adrenergic receptor agonist, providing nasal decongestion through vasoconstriction of the nasal blood vessels, thereby reducing swelling and congestion. This combination offers a comprehensive approach to managing cold symptoms, including nasal congestion, sneezing, and rhinorrhea. Zukamin Cold Oral Drops are indicated for adults and children above the age of two years, with dosage adjusted accordingly. The medication should be used with caution in patients with hypertension, cardiovascular disease, hyperthyroidism, or glaucoma, and it is contraindicated in individuals with hypersensitivity to any of the components. Common side effects may include dizziness, dry mouth, and mild gastrointestinal discomfort. It is recommended to consult a healthcare professional before use, especially in pregnant or lactating women. Zukamin Cold Oral Drops provide effective symptomatic relief, improving patient comfort during upper respiratory tract infections and allergic episodes.
