Bambuterol (INN) is a long-acting β adrenoceptor agonist (LABA) used in the treatment of asthma; it also is a prodrug of terbutaline. Commercially, the AstraZeneca pharmaceutical company produces and markets bambuterol as Bambec and Oxeol.[1]
As other LABAs, bambuterol is used in the long-term management of persistent asthma.[1] It should not be used as a rescue medication for short-term relief of asthma symptoms.
Contraindications[]
Bambuterol is contraindicated in pregnancy and in people with seriously impaired liver function. It can be used by people with renal impairment, but dose adjustments are necessary.[1]
Adverse effects[]
The adverse effect profile of bambuterol is similar to that of salbutamol, and may include fatigue, nausea, palpitations, headache, dizziness and tremor.[1]
Interactions[]
Concomitant administration of bambuterol with corticosteroids, diuretics, and xanthine derivatives (such as theophylline) increases the risk of hypokalemia (decreased levels of potassium in the blood).[2]
Bambuterol acts as a cholinesterase inhibitor, and can prolong the duration of action of suxamethonium (succinylcholine) and other drugs whose breakdown in the body depends on cholinesterase function.[1] Butyrylcholinesterase activity returns to normal approximately two weeks after bambuterol is stopped.[3] It can also enhance the effects of non-depolarizingneuromuscular blockers, such as vecuronium bromide.[2]
