Harkof AD Syrup Sugar Free is a multi-action respiratory formulation designed to provide symptomatic relief from cough, cold, and associated respiratory conditions. It contains Ambroxol (15mg/5ml), a mucolytic agent that facilitates the breakdown and clearance of mucus from the respiratory tract, enhancing expectoration. Dextromethorphan Hydrobromide (10mg/5ml) acts as a centrally acting antitussive, effectively suppressing dry and irritating cough. Phenylephrine (5mg/5ml), a selective alpha-1 adrenergic receptor agonist, provides nasal decongestion by constricting dilated blood vessels in the nasal mucosa, thereby reducing swelling and congestion. Chlorpheniramine Maleate (2mg/5ml) is an antihistamine that alleviates allergic symptoms such as runny nose, sneezing, and watery eyes by blocking histamine H1 receptors. Menthol (1.5mg/5ml) imparts a cooling sensation and mild analgesic effect, soothing the throat and enhancing patient comfort. The sugar-free formulation makes it suitable for diabetic patients and those requiring controlled sugar intake. Harkof AD Syrup Sugar Free is indicated for the management of acute respiratory tract infections, allergic rhinitis, and cough associated with mucus hypersecretion. It should be used under medical supervision, adhering to recommended dosages to ensure safety and efficacy.
