Final answer:
Common side effects of B2 agonists include tremors, increased heart rate, hypertension, and gastrointestinal issues such as indigestion and changes in bowel movements like diarrhea or constipation.
Step-by-step explanation:
The common side effects of B2 agonists include an array of symptoms due to their action on the beta-2 adrenergic receptors. These receptors primarily promote smooth muscle relaxation in the airways, leading to bronchodilation which is helpful in conditions such as asthma. However, B2 agonists can also lead to side effects such as tremors and insomnia due to their systemic effects.
While B2 agonists are intended to relax the bronchial muscles, their systemic effects might result in an increased heart rate and hypertension, which are common side effects. In some cases, these medications can also cause gastrointestinal issues like indigestion, heartburn, and changes in bowel movements which might include diarrhea or constipation.
In summary, while B2 agonists are effective for treating asthma and other respiratory issues, they can sometimes cause unwanted side effects involving the cardiovascular and digestive systems.
