Tulobuterol（Cat No.:R005983）is a long-acting β2-adrenergic receptor agonist used primarily as a bronchodilator in the treatment of asthma and chronic obstructive pulmonary disease (COPD). Unlike many β2-agonists, it is unique for being administered via a transdermal patch, offering sustained release and stable plasma concentrations. This route provides prolonged therapeutic effects, improved compliance, and reduced dosing frequency compared to inhaled forms. Tulobuterol improves airflow by relaxing bronchial smooth muscles, reducing symptoms like wheezing and breathlessness. Its convenient once-daily patch delivery makes it especially beneficial for children and elderly patients.
