Which is a “Soft steroid” used in bronchial asthma
**Core Concept**
Corticosteroids are a class of medications used to treat inflammatory conditions, including bronchial asthma. Soft steroids, also known as "steroid-sparing agents" or "second-generation corticosteroids," are a type of corticosteroid with a lower risk of systemic side effects and a more favorable therapeutic index.
**Why the Correct Answer is Right**
The correct answer is a "soft steroid" because it has a lower glucocorticoid potency compared to traditional corticosteroids, resulting in fewer systemic side effects. This makes it an ideal choice for long-term treatment of bronchial asthma, particularly in patients who require frequent corticosteroid use. The mechanism of action of this soft steroid involves reducing inflammation by inhibiting the production of pro-inflammatory cytokines and mediators.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it is not a soft steroid. Traditional corticosteroids, such as prednisolone, have a higher glucocorticoid potency and are associated with a higher risk of systemic side effects.
* **Option B:** This option is incorrect because it is not a soft steroid. Corticosteroids with a high mineralocorticoid potency, such as fludrocortisone, are not typically used to treat bronchial asthma.
* **Option D:** This option is incorrect because it is not a soft steroid. Corticosteroids with a high glucocorticoid potency, such as dexamethasone, are not typically used as a first-line treatment for bronchial asthma due to their high risk of systemic side effects.
**Clinical Pearl / High-Yield Fact**
The term "soft steroid" is often used to describe second-generation corticosteroids, which have a lower glucocorticoid potency and a more favorable therapeutic index compared to traditional corticosteroids. These medications are ideal for long-term treatment of bronchial asthma and other inflammatory conditions.
**Correct Answer:** B. Budesonide
