Final answer:
Salbutamol, commonly used for asthma, primarily causes tachycardia and can also lead to increased blood lactate levels and hypokalemia as side effects.
Step-by-step explanation:
The Side Effect of Salbutamol
Salbutamol is a medication used primarily for the treatment of asthma and other conditions with reversible airways obstruction. It works by stimulating beta-2 adrenergic receptors in the lungs which leads to the relaxation of smooth muscle in the airways and helps to open them, making breathing easier.
Common side effects of Salbutamol can include symptoms such as tremors, headache, hyperactivity, and sleep disturbances. Specifically, a notable side effect of Salbutamol is tachycardia (increased heart rate), not bradycardia, because it has a stimulating effect on the heart. Salbutamol can also lead to increased blood lactate levels and hypokalemia (decreased potassium levels) as it drives potassium into cells, causing a decrease in the concentration of potassium in the blood.
