Final answer:
An α2 agonist is a drug that activates the α2 adrenergic receptor, with one of its specific actions being the inhibition of insulin release in the pancreas. Common side effects of α2 agonists include sedation, drowsiness, dry mouth, and low blood pressure.
Step-by-step explanation:
An α2 agonist is a drug that activates the α2 adrenergic receptor in the body. This receptor is involved in various functions, one of which is the inhibition of insulin release in the pancreas. Examples of α2 agonists include clonidine and dexmedetomidine.
Classic side effects of α2 agonists may vary depending on the specific drug used, but common side effects include sedation, drowsiness, dry mouth, and low blood pressure. These side effects are due to the drug's effect on α2 receptors in the central nervous system.
