PROVENTIL-HFA is a metered-dose inhaler (MDI) containing albuterol sulfate, a selective beta-2 adrenergic agonist that relaxes bronchial smooth muscle and improves airflow. It is indicated for the treatment and prevention of bronchospasm in patients with reversible obstructive airway disease, including asthma. The drug works by stimulating adenyl cyclase to increase cyclic AMP, producing rapid bronchodilation with onset within 5 minutes and peak effect at approximately 1 hour.
