Zeet Syrup is a multi-ingredient pharmaceutical formulation containing Diphenhydramine hydrochloride (10mg/5ml), Ammonium Chloride (100mg/5ml), and Sodium Citrate (60mg/5ml), designed to provide symptomatic relief in respiratory tract conditions characterized by cough and congestion. Diphenhydramine, a first-generation antihistamine, exerts anticholinergic and sedative effects, effectively reducing allergic symptoms and suppressing cough reflex. Ammonium Chloride acts as an expectorant, facilitating the loosening and thinning of mucus in the airways, thereby promoting productive cough and easing expectoration. Sodium Citrate functions as a mucolytic and alkalinizing agent, helping to reduce mucus viscosity and maintain optimal pH balance in respiratory secretions, which enhances mucociliary clearance. Zeet Syrup is indicated for the management of cough associated with upper respiratory tract infections, bronchitis, and other conditions involving excessive mucus production. It should be used with caution in patients with a history of hypersensitivity to any component, glaucoma, or prostatic hypertrophy due to the anticholinergic effects of Diphenhydramine. The syrup is intended for oral administration, with dosage adjusted according to age and clinical condition as advised by a healthcare professional. Adverse effects may include drowsiness, dry mouth, and gastrointestinal disturbances. Consultation with a physician is recommended prior to use, especially in pediatric and elderly populations.
