Description

Fenoterol is a beta2-adrenoreceptor agonist, used as a bronchodilator for the treatment and prevention of bronchospasms, associated with asthma and chronic obstructive airway disease, including bronchitis and pulmonary emphysema. Fenoterol is also used for tocolysis during premature labor. Marketing of fenoterol for treatment of asthma was suspended in Australia and New Zealand because of an increased risk of deaths, most likely due to excessive self-administration of the drug.

Sample Use Guides

In Vivo Use Guide
Fenoterol was available as inhalation aerosol and inhalation solution. As a bronchodilator aerosol in adults, 2 inhalations (100 or 200 mcg), three to four times a day, if necessary, but not to be administered more often than every four hours. Dosage should not exceed 8 inhalations of the 100 mcg per metered spray formulation or 6 inhalations of the 200 mcg per metered spray formulation per day. As an aid for prematue labor, fenoterol was used by i.v. infusion or p.o.

In Vitro Use Guide
Ability of fenoterol to activate beta2 adrenergic receptors was tested in beta2 receptors expressed in CHO cells using Adenylyl cyclase activity assay. 50 ug membrane protein was incubated with a buffer solution in the presence of 32P-ATP and test compound, and accumulation of 32P-cAMP was determined by beta-counter. Fenoterol activates beta2 receptor with Emax of 76% relative to isoproterenol.
