Bambec (Bambuterol) is converted into terbutaline in the body. Terbutaline acts by stimulating beta adrenergic receptors in many parts of the body. Stimulation of beta receptors in the lungs causes relaxation of the muscles surrounding the air passages (bronchioles), allowing the airways to open.
In conditions, such as asthma, where the muscles contract and the lining swells, narrowing the airways, it is difficult for air to pass in and out of the lungs. By opening the airways, terbutaline reverses the effects of asthma and improves breathing.
Bambec is formulated as a tablet and should be taken once daily, shortly before bedtime. The dose should be individualised. Adults: The recommended starting doses are 10mg-20mg. The 10mg dose may be increased to 20mg if necessary after 1-2 weeks, depending on the clinical effect. In patients who have previously tolerated ß2-agonists well, the recommended starting dose, as well as maintenance dose, is 20mg.
Children: Until the clinical documentation has been completed, Bambec should not be used in children.
Elderly: Dose adjustment is not required in the elderly.
Significant hepatic dysfunction: Not recommended because of unpredictable conversion to terbutaline.
Moderate to severely impaired renal function (GFR < 50ml/min): It is recommended that the starting dose of Bambec should be halved in these patients.
As terbutaline is excreted mainly via the kidneys, the dose of Bambec should be halved in patients with moderately to severely impaired renal function (GFR 50 mL/min).
Care should be taken with patients suffering from myocardial insufficiency or thyrotoxicosis.
Due to the hyperglycaemic effects of ß2-stimulants, additional blood glucose measurements are recommended initially when Bambec therapy is commenced in diabetic patients.
Due to the positive inotropic effects of ß2-agonists these drugs should not be used in patients with hypertrophic cardiomyopathy.
