Grilinctus Syrup is a multi-ingredient expectorant and antitussive formulation designed to provide symptomatic relief from cough and associated respiratory conditions. Each 5 ml of Grilinctus contains Ammonium Chloride 60 mg, Chlorpheniramine Maleate 2.5 mg, Dextromethorphan Hydrobromide 5 mg, and Guaifenesin 50 mg. Ammonium Chloride acts as an expectorant, facilitating the loosening and thinning of mucus in the airways, thereby promoting productive cough. Chlorpheniramine Maleate, an antihistamine, helps alleviate allergic symptoms such as nasal congestion, runny nose, and sneezing by blocking histamine H1 receptors. Dextromethorphan Hydrobromide serves as a centrally acting cough suppressant, reducing the frequency and intensity of dry, non-productive cough. Guaifenesin enhances mucus clearance by increasing respiratory tract fluid secretions, aiding in the expectoration process. Grilinctus Syrup is indicated for the treatment of cough associated with upper respiratory tract infections, bronchitis, and allergic conditions. It should be used with caution in patients with a history of hypersensitivity to any component, and under medical supervision in individuals with asthma, chronic bronchitis, or other respiratory disorders. Dosage should be adhered to as per physician’s recommendation to avoid potential side effects such as drowsiness or gastrointestinal discomfort.
