XL 80 LS Expectorant Sugar Free is a multi-action respiratory formulation containing Levosalbutamol (1mg/5ml), Ambroxol (30mg/5ml), and Guaifenesin (50mg/5ml). This combination is designed to provide effective relief from symptoms associated with respiratory tract disorders characterized by bronchospasm, excessive mucus production, and cough. Levosalbutamol, a selective beta-2 adrenergic agonist, acts as a bronchodilator by relaxing bronchial smooth muscles, thereby improving airflow and alleviating wheezing and shortness of breath. Ambroxol serves as a mucolytic agent, facilitating the breakdown and clearance of viscous mucus, enhancing mucociliary transport, and promoting easier expectoration. Guaifenesin, an expectorant, increases respiratory tract fluid secretion, reducing mucus viscosity and aiding in the clearance of phlegm. The sugar-free formulation is suitable for patients with diabetes or those requiring sugar-restricted diets. XL 80 LS Expectorant Sugar Free is indicated for the symptomatic management of acute and chronic bronchitis, asthma, chronic obstructive pulmonary disease (COPD), and other conditions involving bronchial congestion and cough. It should be used under medical supervision, with dosage adjusted according to patient age and clinical response. Caution is advised in patients with cardiovascular disorders, hyperthyroidism, or hypersensitivity to any component.
