Which route is used for the administration of fludrocortisone?

Fludrocortisone is primarily administered orally, which makes the oral route the correct choice for its administration. This is due to the fact that fludrocortisone is a synthetic mineralocorticoid that helps in regulating sodium and potassium levels in the body by mimicking the action of aldosterone.

The oral administration facilitates consistent absorption in the gastrointestinal tract, allowing for effective management of conditions such as Addison's disease or orthostatic hypotension related to adrenal insufficiency. Additionally, the oral route is convenient and non-invasive, which enhances patient compliance.

Other routes such as intravenous, subcutaneous, or intramuscular are not typically used for fludrocortisone because they may involve more complexity in administration without providing a therapeutic advantage over the oral route. Additionally, the pharmacologic properties and the required dosage forms of fludrocortisone are optimally designed for oral delivery.
