This is a list of 5α-reductase inhibitors (5α-RIs), drugs which inhibit one or more isoforms of the enzyme 5α-reductase.This enzyme is responsible for the conversion of the androgen hormone testosterone into the more potent dihydrotestosterone (DHT) and is essential for the production of neurosteroids like allopregnanolone, tetrahydrodeoxycorticosterone (THDOC), and 3α-androstanediol from ...
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 .

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 ...
Patients on high dose sulfasalazine require folic supplementation (1 mg/day) because it inhibits folate absorption. If oral Mesalazine is still not working, prednisone is often given, starting at 40–60 mg/day. Prednisone often takes effect within 10–14 days. The dose should then be tapered by about 5 mg/week until it can be stopped altogether.
Depo-Medrol is available as sterile aqueous solution in 20 mg/mL, 40 mg/mL, or 80 mg/mL strengths. [23] Solu-Medrol is the only derivative of methylprednisolone that is approved for intravenous infusion, as the sterile powder is soluble in water and can be mixed with a diluent. Strengths vary from 40 mg to 2 g. [22]
Generally, tapering is done is to avoid or minimize withdrawal symptoms that arise from neurobiological adaptation to the drug. [1] [2] Prescribed psychotropic drugs that may require tapering due to this physical dependence include opioids, [3] [4] [5] selective serotonin reuptake inhibitors, [6] antipsychotics, [7] anticonvulsants, [8] and ...
