Quizplus · Accepted Answer

A fi₂agonist is a drug that stimulates the beta2-adrenergic receptors in the lungs, causing smooth muscle relaxation and ultimately leading to an increase in the diameter of the respiratory passageways. This makes it easier for air to flow in and out of the lungs and can help alleviate symptoms of conditions such as asthma.
