Overview

The two main classes of corticosteroids are glucocorticoids and mineralocorticoids. They play a crucial role in a wide range of physiological processes:

stress response immune response regulation of inflammation carbohydrate metabolism protein catabolism blood electrolyte levels behavior

Synthesis and regulation

Corticosteroids are synthesized in the adrenal cortex, which is part of the adrenal gland. The production and release of these hormones are regulated by the hypothalamus and the pituitary gland through the hypothalamic-pituitary-adrenal axis (HPA axis).

Clinical uses

Corticosteroids have a variety of clinical applications due to their anti-inflammatory, immunosuppressive, and hormone replacement properties. They are used to treat conditions such as:

• Asthma
• Autoimmune diseases
• Inflammatory bowel disease
• Allergic reactions
• Rheumatoid arthritis
• Adrenal insufficiency

Side effects and precautions

Long-term use of corticosteroids can lead to side effects, including:

• Cushing's syndrome
• Osteoporosis
• Hyperglycemia
• Glaucoma
• Muscle weakness
• Immunosuppression

To minimize these risks, corticosteroids are often prescribed at the lowest effective dose for the shortest duration necessary.
