Is corticosterone a glucocorticoid?

Corticosterone is generally not classified as a glucocorticoid. The detailed explanation is as follows:

As an organic compound, corticosterone is primarily used to treat adrenal cortical insufficiency, but it does not belong to the class of glucocorticoids; rather, it is a mineralocorticoid. Corticosterone helps maintain the body's electrolyte and water balance and enhances the reabsorption capacity of renal tubules. It also provides certain protective effects on the gastrointestinal tract, salivary glands, and other tissues. If corticosterone levels in the body are low, it may lead to slowed blood circulation, resulting in symptoms such as hypotension and loss of sodium and water. Therefore, this compound can also be used to increase blood pressure and is often included as an ingredient in some medications for treating hypotension. Furthermore, current research suggests that corticosterone may improve insulin sensitivity, lower blood glucose levels, and help prevent conditions such as diabetes and acute myocardial infarction.

It is recommended that individuals seek timely medical attention if they experience any discomfort in daily life, accurately identify the underlying cause, and receive targeted treatment. Any medication use must be conducted under the guidance of a qualified physician.
