Winituss-DMR Tablet is a combination medication formulated to provide comprehensive relief from symptoms associated with respiratory tract infections and allergic conditions. It contains Ambroxol (30mg/5ml), a mucolytic agent that facilitates the breakdown and clearance of mucus, thereby improving airway patency. Cetirizine (5mg/5ml), a second-generation antihistamine, effectively alleviates allergic symptoms such as sneezing, runny nose, and itching by selectively inhibiting peripheral H1 receptors. Dextromethorphan Hydrobromide (10mg/10ml) acts as a centrally acting antitussive, suppressing the cough reflex to reduce the frequency and severity of dry, non-productive cough. Guaifenesin (100mg/5ml) serves as an expectorant, promoting the loosening and expulsion of mucus from the respiratory tract, enhancing productive cough. Phenylephrine (15mg/5ml), a selective alpha-1 adrenergic receptor agonist, provides symptomatic relief from nasal congestion by inducing vasoconstriction of nasal mucosal blood vessels. The synergistic action of these active ingredients makes Winituss-DMR Tablet an effective therapeutic option for managing cough, congestion, mucus hypersecretion, and allergic manifestations. It is recommended to be used under medical supervision, with caution advised in patients with hypertension, cardiac disorders, or hypersensitivity to any component.
