Initial Drug of choice for suspected case of acute adrenal insufficiency is:
**Core Concept**
Acute adrenal insufficiency, also known as adrenal crisis, occurs when the adrenal glands fail to produce sufficient cortisol and aldosterone hormones, leading to a life-threatening condition. The initial management involves administering glucocorticoids to stabilize the patient.
**Why the Correct Answer is Right**
The correct answer is hydrocortisone, a synthetic glucocorticoid that mimics the action of cortisol. Hydrocortisone is the preferred initial treatment for acute adrenal insufficiency because it has both glucocorticoid and mineralocorticoid effects, which helps to restore the deficient hormone levels. The administration of hydrocortisone should be done intravenously, and the dosage should be based on the patient's weight and clinical condition.
**Why Each Wrong Option is Incorrect**
**Option A:** Fluorcortisone is a synthetic mineralocorticoid, but it lacks significant glucocorticoid activity, making it inadequate as the initial treatment for acute adrenal insufficiency.
**Option B:** Prednisolone is a synthetic glucocorticoid, but it has a longer duration of action and is not suitable for acute adrenal insufficiency due to its slower onset of action.
**Option C:** Dexamethasone is a synthetic glucocorticoid with a long duration of action, but it lacks mineralocorticoid activity, making it less ideal as the initial treatment for acute adrenal insufficiency.
**Clinical Pearl / High-Yield Fact**
In cases of suspected acute adrenal insufficiency, it's essential to administer hydrocortisone promptly, as delayed treatment can lead to severe consequences, including shock, hypotension, and even death.
**Correct Answer: C. Hydrocortisone**
