Ontus Plus Syrup is a combination expectorant and bronchodilator formulation containing Bromhexine (4mg/5ml), Guaifenesin (50mg/5ml), Menthol (1mg/5ml), and Terbutaline (1.25mg/5ml). This multi-ingredient syrup is indicated for the symptomatic relief of respiratory conditions characterized by productive cough and bronchospasm, such as acute and chronic bronchitis, asthma, and other obstructive airway diseases. Bromhexine acts as a mucolytic agent, facilitating the breakdown and clearance of viscous mucus from the respiratory tract, thereby improving airway patency. Guaifenesin serves as an expectorant, promoting the loosening and expulsion of phlegm, which aids in effective cough clearance. Menthol provides a soothing effect on the respiratory mucosa and contributes to symptomatic relief through its mild local anesthetic and cooling properties. Terbutaline, a selective beta-2 adrenergic receptor agonist, exerts bronchodilatory effects by relaxing bronchial smooth muscle, thus alleviating bronchospasm and improving airflow. Ontus Plus Syrup 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. This combination therapy offers comprehensive relief by addressing mucus viscosity, cough clearance, airway inflammation, and bronchoconstriction.
