Albuterol - ANSWER ✔✔Classification: Bronchodilator, beta agonist
Action: Binds and stimulates beta2 receptors, resulting in relaxation of
bronchial
smooth muscle.

,Adverse Effects: Hyperglycemia, hypokalemia, palpitations, sinus
tachycardia,
anxiety, tremor, nausea/vomiting, throat irritation, dry mouth,
