Lincotus LS Expectorant Sugar Free is a combination oral syrup formulated to provide effective relief from respiratory tract conditions characterized by cough and excessive mucus production. It contains Levosalbutamol (1mg/5ml), a selective β2-adrenergic receptor agonist that acts as a bronchodilator, facilitating the relaxation of bronchial smooth muscles and improving airflow in obstructive airway diseases such as asthma and chronic bronchitis. Ambroxol (30mg/5ml) serves as a mucolytic agent, promoting the breakdown and clearance of viscous mucus by stimulating surfactant production and enhancing ciliary activity in the respiratory tract. Guaifenesin (50mg/5ml) is an expectorant that aids in loosening and thinning mucus, thereby facilitating productive cough and improving expectoration. This sugar-free formulation is suitable for patients with diabetes or those requiring sugar-restricted diets. Lincotus LS Expectorant Sugar Free is indicated for symptomatic relief of cough associated with bronchitis, asthma, and other respiratory conditions involving mucus hypersecretion and bronchospasm. It should be used under medical supervision, with dosage adjusted according to patient age and clinical condition. Caution is advised in patients with cardiovascular disorders, hypersensitivity to components, or concurrent use of other bronchodilators.
