Zedex-P Syrup is a multi-ingredient formulation designed to provide symptomatic relief from common cold and allergic conditions. It contains Chlorpheniramine Maleate (0.5mg/5ml), an antihistamine that alleviates allergic symptoms such as sneezing, runny nose, and watery eyes by blocking histamine H1 receptors. Paracetamol (125mg/5ml) serves as an analgesic and antipyretic agent, effectively reducing fever and relieving mild to moderate pain. Phenylephrine (5mg/5ml) is a selective alpha-1 adrenergic receptor agonist that acts as a nasal decongestant by constricting dilated blood vessels in the nasal mucosa, thereby reducing nasal congestion. Sodium Citrate (60mg/5ml) functions as an expectorant and mucolytic, helping to loosen mucus and facilitate its clearance from the respiratory tract. Menthol (1mg/5ml) provides a cooling sensation and mild local anesthetic effect, contributing to symptomatic relief of throat irritation and cough. Zedex-P Syrup is indicated for the management of symptoms associated with upper respiratory tract infections, allergic rhinitis, and common cold. It should be used as directed by a healthcare professional, with caution advised in patients with hypertension, cardiac conditions, or hypersensitivity to any components. This combination offers comprehensive symptomatic relief, improving patient comfort during illness.
