Prednisone is a prodrug and must be converted to prednisolone by the liver before it becomes active. [6] [7] Prednisolone then binds to glucocorticoid receptors, activating them and triggering changes in gene expression. [4] Prednisone was patented in 1954 and approved for medical use in the United States in 1955.
Prednisolone is a synthetic pregnane corticosteroid closely related to its cognate prednisone, having identical structure save for two fewer hydrogens near C 11. It is also known as δ 1 -cortisol , δ 1 -hydrocortisone , 1,2-dehydrocortisol , or 1,2-dehydrohydrocortisone , as well as 11β,17α,21-trihydroxypregna-1,4-diene-3,20-dione .
R-miniCHOP is indicated in elderly patients (>80 years) with diffuse large B-cell lymphoma due to less toxicity from the reduced dose in comparison to R-CHOP. R-Maxi-CHOP is used in mantle cell lymphoma and is given in 21-day intervals, alternating with R-HDAC (rituximab + high-dose cytarabine).
The medications included prednisone, and methylprednisolone, plus albuterol, beclomethasone, dexamethasone, cromolyn, salmeterol and clarithromycin. Within days of beginning the glucocorticoid treatment, however, the patient began to show symptoms that included major depression, irritability, muscle weakness, and hallucinations ("stars" or ...

Addison's disease, also known as primary adrenal insufficiency, [4] is a rare long-term endocrine disorder characterized by inadequate production of the steroid hormones cortisol and aldosterone by the two outer layers of the cells of the adrenal glands (adrenal cortex), causing adrenal insufficiency.
Fever, tiredness, unspecific arthralgias, or myalgias are commonly treated with nonsteroidal anti-inflammatory medications (NSAIDs), hydroxychloroquine, or a low dose of prednisone, depending on the severity. [68] Mild joint involvement can be effectively treated with NSAIDs, hydroxychloroquine, and oral prednisone.
So, for example, digoxin has a half-life (or t 1 / 2 ) of 24–36 h; this means that a change in the dose will take the best part of a week to take full effect. For this reason, drugs with a long half-life (e.g., amiodarone , elimination t 1 / 2 of about 58 days) are usually started with a loading dose to achieve their desired ...
