Xanphyl 200 Tablet SR contains Acebrophylline 200mg, a bronchodilator and mucolytic agent used primarily in the management of respiratory conditions such as chronic obstructive pulmonary disease (COPD), asthma, and bronchitis. Acebrophylline acts by relaxing the smooth muscles of the airways, thereby improving airflow and reducing bronchospasm. Additionally, it exhibits mucokinetic and mucolytic properties, facilitating the clearance of mucus from the respiratory tract, which aids in alleviating cough and improving breathing. The sustained-release formulation ensures a prolonged therapeutic effect, allowing for twice-daily dosing and enhancing patient compliance. Xanphyl 200 Tablet SR is indicated for patients experiencing airway obstruction with excessive mucus production and is often prescribed as part of a comprehensive treatment plan including bronchodilators and corticosteroids. It is generally well-tolerated; however, common side effects may include gastrointestinal discomfort, headache, and mild dizziness. Caution is advised in patients with hypersensitivity to xanthine derivatives, cardiac arrhythmias, or peptic ulcer disease. Consultation with a healthcare professional is recommended before initiating therapy to ensure appropriate use and to monitor for potential drug interactions. Xanphyl 200 Tablet SR represents an effective option in the symptomatic management of obstructive airway diseases.
