Which of the following is NOT an adverse effect of Salbutamol? (AIIMS Nov 2013)



A Tachycardia
B Tolerance

C Hypokalemia
D Hypoglycemia

Ans. D Hypoglycemia (Ref: KDT's 6th/127)

Beta 2 agonists like salbutamol and terbutaline can cause several adverse effects like:

Tachycardia due to stimulation of chronotropic ~2 receptors and at high dose due to stimulation of ~l receptors also.

Tremors may result due to stimulation of muscle spindles.

Tolerance may develop due to densensitization of receptors.

Transient hyperkalemia followed by prolonged hypokalemia is seen on continued use.

Hyperglycemia may develop due to release of glucagon and stimulation of glycogenolysis and gluconeogenesis.
