Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones.Two main classes of corticosteroids, glucocorticoids and mineralocorticoids, are involved in a wide range of physiological processes, including stress response, immune response, and regulation of inflammation, carbohydrate metabolism ...
The major mechanism for this immunosuppression is through inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells . NF-κB is a critical transcription factor involved in the synthesis of many mediators (i.e., cytokines) and proteins (i.e., adhesion proteins) that promote the immune response.
Methylprednisolone (Depo-Medrol, Medrol, Solu-Medrol) is a synthetic glucocorticoid, primarily prescribed for its anti-inflammatory and immunosuppressive effects. [4] [5] [6] It is either used at low doses for chronic illnesses or used concomitantly at high doses during acute flares.
The first identified mechanisms of steroid hormone action were the genomic effects. [12] In this pathway, the free hormones first pass through the cell membrane because they are fat soluble. [7] In the cytoplasm, the steroid may or may not undergo an enzyme-mediated alteration such as reduction, hydroxylation, or aromatization.
The opposite mechanism is called transrepression. The hormone receptor without ligand binding interacts with heat shock proteins and prevents the transcription of targeted genes. Aldosterone and cortisol (a glucosteroid ) have similar affinity for the mineralocorticoid receptor; however, glucocorticoids circulate at roughly 100 times the level ...
Prednisolone has a relatively short half-life, ranging 2–4 hours. It also has a large therapeutic window, considering the dosage required to produce a therapeutic effect is a few times higher than what the body naturally produces. [14] Prednisolone is 70–90% plasma protein bound, it binds to proteins such as albumin. [14]
Deflazacort's potency is around 70–90% that of prednisone. [8] A 2017 review found its activity of 7.5 mg of deflazacort is approximately equivalent to 25 mg cortisone, 20 mg hydrocortisone, 5 mg of prednisolone or prednisone, 4 mg of methylprednisolone or triamcinolone, or 0.75 mg of betamethasone or dexamethasone.
