Which statement correctly contrasts inhaled corticosteroids with systemic corticosteroids regarding indication, systemic exposure, and common adverse effects?

• A. Inhaled corticosteroids provide targeted airway anti-inflammatory effects with minimal systemic exposure; systemic corticosteroids are used for severe or systemic inflammation and have higher risks such as adrenal suppression, hyperglycemia, osteoporosis, and weight gain.
• B. Inhaled corticosteroids have systemic exposure greater than oral prednisone.
• C. Systemic corticosteroids have fewer adverse effects than inhaled.</br>
• D. Inhaled corticosteroids are used for acute severe asthma flares.

Answer: (A)

Understanding how the route of administration changes both where a corticosteroid works and how much it affects the rest of the body is the main idea here. Inhaled corticosteroids deliver anti-inflammatory action directly to the airways, achieving strong local effects with only minimal systemic exposure. This makes them ideal for long-term control of chronic airway inflammation, such as in asthma, while keeping systemic risks low. The adverse effects you see with inhaled forms are mainly local: oropharyngeal candidiasis and hoarseness; systemic effects are uncommon unless very high doses are used or in susceptible individuals. Systemic corticosteroids, given orally or by IV, provide widespread glucocorticoid exposure, which is why they’re used for severe or systemic inflammation and acute exacerbations when a rapid, broad anti-inflammatory effect is needed. That greater systemic exposure brings higher risks of adverse effects such as adrenal suppression, hyperglycemia, osteoporosis, and weight gain. So the statement correctly contrasts the two: inhaled corticosteroids offer targeted airway relief with minimal systemic exposure and mainly local adverse effects, while systemic steroids are used for severe or systemic inflammation and carry higher systemic risks. The other options either overstate systemic exposure for inhaled formulations, imply fewer adverse effects with systemic steroids, or misstate that inhaled corticosteroids are used for acute severe asthma flares.
