Glucocorticoid corticosteroids are used to treat systemic lupus, severe psoriasis, leukemia, lymphomas, idiopathic thrombocytopenic purpura, and autoimmune hemolytic anemia. These corticosteroids also are used to suppress the immune system and prevent rejection in people who have undergone organ transplant as well as many other conditions.
Fludrocortisone (Florinef), a potent systemic oral mineralocorticoid corticosteroid is used to treat Addison's disease and diseases that cause salt loss as in congenital adrenal hyperplasia. It also is used commonly to treat conditions of low blood pressure (hypotension) although this is not a Food and Drug Administration (FDA) approved indication.
Are there any differences among the different types of systemic corticosteroids?
Corticosteroids differ in their relative amount of anti-inflammatory and mineralocorticoid potency and they are used according to these effects. Among the systemic (oral and injectable) corticosteroids, fludrocortisone (Florinef) has the most significant mineralocorticoid (salt retaining) actions and is best used for this effect despite it's strong anti-inflammatory action.
Other systemically available corticosteroids have mostly glucocorticoid effects, and are used for their anti-inflammatory activities. Examples of these include the naturally occurring hydrocortisone (Cortef) and cortisone, and the synthetic corticosteroids including:
Among all glucocorticoids, prednisone is not effective in the body unless it is converted to prednisolone by enzymes in the liver. For this reason prednisone may not be very effective in people with liver disease because of a reduction in their ability to convert prednisone to prednisolone.
What are the side effects of systemic corticosteroids?
Corticosteroids have many side effects that can be mild or serious. These side effects are more apparent when corticosteroids are used at higher doses or for extended periods of time. This section lists only some of these side effects of corticosteroids.
The prolonged use of corticosteroids can cause obesity, growth retardation in children, and even lead to convulsions and psychiatric disturbances. Reported psychiatric disturbances include depression, euphoria, insomnia, mood swings, and personality changes. Psychotic behaviors also have been reported.
Corticosteroids, since they suppress the immune system, can lead to an increase in the rate of infections and reduce the effectiveness of vaccines and antibiotics.
The long term use of corticosteroids may cause osteoporosis which can result in bone fractures.
