Kofsooth LS Syrup Sugar Free is a combination expectorant and bronchodilator formulation containing Ambroxol 30mg, Levosalbutamol 1mg, and Guaifenesin 50mg per 5ml. Ambroxol acts as a mucolytic agent, facilitating the breakdown and clearance of mucus from the respiratory tract, thereby improving airway patency. Levosalbutamol, a selective β2-adrenergic receptor agonist, provides bronchodilation by relaxing bronchial smooth muscle, which helps alleviate bronchospasm and improves airflow in obstructive airway conditions. Guaifenesin serves as an expectorant, promoting the thinning and loosening of mucus, which aids in effective expectoration. This sugar-free syrup is indicated for symptomatic relief in respiratory disorders characterized by productive cough and bronchospasm, such as chronic bronchitis, asthma, and other obstructive airway diseases. The combination therapy targets multiple pathophysiological mechanisms, enhancing mucociliary clearance and bronchodilation, thus improving respiratory function and patient comfort. Kofsooth LS Syrup Sugar Free should be used under medical supervision, with dosage adjusted according to patient age and severity of symptoms. It is contraindicated in patients with hypersensitivity to any component and should be used cautiously in those with cardiovascular disorders or hyperthyroidism.
