Berotec Drug Interactions

Beta-adrenergics, anticholinergics and xanthine derivatives (eg, theophylline) may enhance the effect of Berotec. The concurrent administration of other β-mimetics, systemically available anticholinergics and xanthine derivatives (eg, theophylline) may increase the side effects.
Hypokalaemia induced by beta₂-agonists may be increased by concomitant treatment with xanthine derivatives, corticosteroids, and diuretics. This should be taken into account particularly in patients with severe airway obstruction.
A potentially serious reduction in bronchodilation may occur during concurrent administration of β-blockers.
Beta-adrenergic agonists should be administered with caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, since the action of β-adrenergic agonists may be enhanced.
Inhalation of halogenated hydrocarbon anaesthetics eg, halothane, trichloroethylene and enflurane may increase the susceptibility to the cardiovascular effects of β-agonists.
