Instaryl-P Syrup is a multi-ingredient formulation designed to provide symptomatic relief in respiratory conditions characterized by bronchospasm, excessive mucus production, and cough. Each 5 ml of syrup contains Terbutaline 1.25 mg, a selective beta-2 adrenergic agonist that acts as a bronchodilator, facilitating the relaxation of bronchial smooth muscles and improving airflow in obstructive airway diseases such as asthma and chronic bronchitis. Ambroxol 15 mg serves as a mucolytic agent, promoting the breakdown and clearance of viscous mucus, thereby enhancing expectoration. Guaifenesin 50 mg acts as an expectorant, increasing respiratory tract fluid secretion to help loosen phlegm and ease productive cough. Levomenthol 2.5 mg provides a soothing effect on the respiratory mucosa, offering mild local anesthetic and cooling properties that alleviate throat irritation and cough reflex sensitivity. Instaryl-P Syrup is indicated for the management of acute and chronic respiratory disorders involving bronchospasm and mucus hypersecretion. It should be used under medical supervision, with caution in patients with cardiovascular disorders, hyperthyroidism, or hypersensitivity to any component. The syrup is intended for oral administration, with dosage adjusted according to patient age and clinical response.
