Indications

Salbutamol is indicated as a bronchodilator for use in Asthma, Chronic Bronchitis, Emphysema and other conditions associated with airways obstruction.

Therapeutic Class

Short-acting selective & β2-adrenoceptor stimulants

Pharmacology

Salbutamol is a selective beta2-adrenoceptor agonist. At therapeutic doses, it acts on the beta 2-adrenoceptors of bronchial smooth muscle, with little or no action on the ß1-adrenoceptors of cardiac muscle. Salbutamol provides short acting (4-6 hours) bronchodilatation with a fast onset (within 5 minutes) in reversible airways obstruction. It also has an anti-inflammatory effect on mast cells causing inhibition of release of bronchoconstrictor mediators including histamine, neutrophil chemotactive factor (NCF) and prostaglandin D2.

Pregnancy & Lactation

Pregnancy: The drug should be used during pregnancy only if the potential benefit justifies the potential risk of the fetus.

Lactation: It is not known whether this drug is excreted in human milk. Because of the potential of tumorigenecity shown for Salbutamol in some animal studies, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Precautions & Warnings

Salbutamol should be used with caution in patients with hyperthyroidism, cardiovascular disease, occlusive vascular disorders, hypertension and aneurysms. Hypokalaemia associated with high doses of Salbutamol may result in increased susceptibility to digitalis-induced cardiac arrhythmia. Tachyphylaxis with resistance may occur with prolonged use of high dosage. Care is necessary when treating patients with diabetes mellitus or closed-angle glaucoma, and in those receiving antihypertensive therapy.

Overdose Effects
