beta 2 adrenergic agonist

Adrenergic receptor agonists are basically a class of drugs that cause smooth muscle relaxation, which in turn causes dilation of bronchial passages, vasodilation in muscle and liver, relaxation of uterine muscle, and release of insulin. According to Wikipedia, Adrenergic receptor agonists are primarily used to “treat asthma and other pulmonary disorders, such as Chronic obstructive pulmonary disease”. When it comes to the side effects, Adrenergic receptor agonists can cause tremor, excessive sweating, anxiety, insomnia, and agitation. Besides, they can also cause more severe side effects such as “paradoxical bronchospasm, hypokalemia, and in rare cases a myocardial infarction”. According to mayoclinic.org, some of these drugs can increase blood sugar, blood pressure, and heart rate in the mother, and may also increase the heart rate and decrease blood sugar in the infant. Therefore, you need to make sure your doctor knows if you are pregnant or may become pregnant before taking any of these medicines.
