Larphylline SR 200 Tablet contains Acebrophylline 200 mg, a bronchodilator used primarily in the management of respiratory conditions such as chronic obstructive pulmonary disease (COPD), bronchitis, and asthma. Acebrophylline exhibits mucolytic, anti-inflammatory, and bronchodilatory properties, facilitating the clearance of mucus from the airways and improving airflow. The sustained-release formulation ensures prolonged therapeutic effects, enhancing patient compliance by reducing dosing frequency. Upon administration, Acebrophylline relaxes the bronchial smooth muscles, leading to bronchodilation and relief from bronchospasm. Additionally, it inhibits the release of inflammatory mediators, thereby reducing airway inflammation and edema. Larphylline SR 200 is indicated as an adjunctive therapy in obstructive airway diseases where mucus hypersecretion and bronchospasm are prominent. It is generally well-tolerated; however, caution is advised in patients with hypersensitivity to xanthine derivatives, cardiac arrhythmias, or peptic ulcers. Common adverse effects may include gastrointestinal discomfort, headache, and mild tremors. Dosage should be individualized based on clinical response and renal function. Larphylline SR 200 should be used under medical supervision, with regular monitoring to optimize therapeutic outcomes and minimize potential side effects.
