Xoomax-DX Syrup is a combination medication formulated to provide symptomatic relief from common cold and allergy-related respiratory conditions. It contains Phenylephrine (5 mg), a selective alpha-1 adrenergic receptor agonist that acts as a decongestant by constricting blood vessels in the nasal mucosa, thereby reducing nasal congestion. Chlorpheniramine Maleate (2 mg) is a first-generation antihistamine that alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking H1 histamine receptors. Dextromethorphan Hydrobromide (15 mg) serves as a centrally acting antitussive agent, suppressing the cough reflex by acting on the medullary cough center without causing significant sedation. Xoomax-DX Syrup is indicated for the relief of nasal congestion, allergic rhinitis, and cough associated with upper respiratory tract infections. It should be used with caution in patients with hypertension, glaucoma, or hyperthyroidism due to the sympathomimetic effects of phenylephrine. The syrup is intended for oral administration, with dosing adjusted according to age and clinical condition. Common adverse effects may include dizziness, drowsiness, dry mouth, and gastrointestinal disturbances. Patients are advised to consult healthcare professionals before use, especially if pregnant, breastfeeding, or taking other medications to avoid potential drug interactions.
