ATC Group: R03CC Selective beta-2-adrenoreceptor agonists
Anatomical Therapeutic Chemical Classification System
Bambuterol is an active precursor of the selective β2-adrenergic agonist terbutaline. Bambuterol is the bis-N,N-dimethyl-carbamate of terbutaline. Bambuterol is a remarkably selective and potent inhibitor of cholinesterase. Bambuterol is indicated for the management of asthma, bronchospasm and/or reversible airways obstruction.
Clenbuterol is a direct-acting β2 sympathomimetic agent for the treatment of chronic obstructive airway diseases.
Salbutamol is a selective β2-agonist providing short-acting (4-6 hour) bronchodilation with a fast onset (within 5 minutes) in reversible airways obstruction. At therapeutic doses it acts on the β2-adrenoceptors of bronchial muscle. Salbutamol is administered for the symptomatic relief of bronchospasm associated with chronic or acute asthma, bronchitis or other obstructive pulmonary diseases.
Terbutaline sulfate is a selective beta2-adrenoceptor agonist, thus producing relaxation of bronchial smooth muscle, inhibition of the release of endogenous spasmogens, inhibitions of oedema caused by endogenous mediators, increased mucociliary clearance and relaxation of the uterine muscle.
