GENERIC NAME: bitolterol mesylate

BRAND NAME: (Tornalate: This brand no longer is available in the U.S. and there are no generic versions.)

DRUG CLASS AND MECHANISM: Bitolterol is a bronchodilator used in the treatment of asthma. It is similar to albuterol (Ventolin). Asthma is a disorder of breathing in which there is narrowing of the airways that carry air to the lungs including the bronchi. This narrowing is caused by muscle spasm and inflammation within the airways. Bitolterol relaxes the smooth muscles surrounding these airways, increasing the diameter and thus easing the flow of air through the airways. Bitolterol probably does not affect inflammation in the lung either with asthma or other inflammatory lung disorders such as bronchitis. Nevertheless, if spasm of the airways occurs because of bronchitis, bitolterol may be useful therapy for the asthmatic component of the illness. Bitolterol is unique in that it is a "prodrug;" It must first be converted by the body into its active form. Bitolterol has a rapid onset of action (2-5 minutes), and its effects may last up to 6-8 hours. The FDA approved bitolterol in December 1984.
