and
Inflammation • Bronchodilators
• This is caused by mast cells releasing o Beta-2 Agonists
substances in response to causative ▪ Albuterol/Terbutaline
stimuli. o Theophylline/Aminophylline
o Bronchoconstriction narrows airways, o Inhaled Anticholinergics
and sphincter action can completely
occlude airways.
▪ This is further aggravated by
inflammation, mucosal edema, and
excessive mucous production.
➢ Symptoms: Dyspnea, wheezing, chest
tightness, cough, and sputum production
