Kep-LS Syrup is a combination expectorant and bronchodilator formulation containing Ambroxol (30mg/5ml), Levosalbutamol (1mg/5ml), and Guaifenesin (50mg/5ml). This multi-ingredient syrup is indicated for the symptomatic relief of respiratory conditions characterized by excessive mucus production, bronchospasm, and cough, such as acute and chronic bronchitis, asthma, and other obstructive airway diseases. Ambroxol acts as a mucolytic agent, facilitating the breakdown and clearance of thick mucus from the respiratory tract, thereby improving airway patency. Levosalbutamol, a selective β2-adrenergic receptor agonist, provides bronchodilation by relaxing bronchial smooth muscles, thus alleviating bronchospasm and improving airflow. Guaifenesin serves as an expectorant, enhancing the hydration of respiratory tract secretions and promoting their clearance through ciliary action. The synergistic effect of these active ingredients results in improved expectoration, reduced airway resistance, and relief from cough and breathlessness. Kep-LS Syrup is administered orally, with dosage tailored according to patient age and severity of symptoms. It is contraindicated in patients with hypersensitivity to any component and should be used cautiously in individuals with cardiovascular disorders or hyperthyroidism. Adverse effects may include mild gastrointestinal disturbances, tremors, or palpitations. Consultation with a healthcare professional is recommended prior to use.
