Bambuterol is a long acting beta-adrenoceptor agonist used in the treatment of asthma. It is a prodrug of terbutaline.
Indication
For the prevention and reversal of bronchospasm in patients 12 years of age and older with asthma and reversible bronchospasm associated with bronchitis and emphysema.
Pharmacology
Bambuterol is a long acting beta2-adrenoceptor agonist used in the treatment of asthma. It is a prodrug of terbutaline. Bambuterol causes smooth muscle relaxation, resulting in dilation of bronchial passages.
Affected Organisms
Humans and other mammals
Biotransformation
Hepatic, extensive. Further metabolized to terbutaline by plasma cholinesterase.
Absorption
Bioavailability is 20% following oral administration.
Half Life
13 hours for bambuterol and 21 hours for the primary active metabolite terbutaline.
A carbamate ester that is terbutaline in which both of the phenolic hydroxy groups have been protected as the corresponding N,N-dimethylcarbamates. A long acting beta-adrenoceptor agonist used in the treatment of asthma, it is a prodrug for terbutaline.
