Grilinctus-LS Syrup is a combination expectorant and bronchodilator formulation containing Ambroxol (30mg/5ml), Levosalbutamol (1mg/5ml), and Guaifenesin (50mg/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 beta-2 adrenergic receptor agonist, provides bronchodilation by relaxing the smooth muscles of the bronchial airways, resulting in relief from bronchospasm and improved airflow in obstructive airway conditions. Guaifenesin serves as an expectorant, promoting the hydration and thinning of bronchial secretions, which enhances mucus clearance and reduces cough frequency. Grilinctus-LS Syrup is indicated for the symptomatic management of respiratory conditions characterized by productive cough and bronchospasm, such as chronic bronchitis, asthma, and other obstructive airway diseases. The synergistic action of its components aids in alleviating cough, facilitating expectoration, and improving breathing ease. It should be used under medical supervision, with dosage adjusted according to patient age and clinical response. Caution is advised in patients with hypersensitivity to any component, cardiovascular disorders, or hyperthyroidism. Adverse effects may include tremors, palpitations, gastrointestinal disturbances, and allergic reactions.
