Prednisolone dosage

The risk of post-transplant diabetes mellitus is greater with tacrolimus than with ciclosporin, but this was mostly true in black patients and during the initial months after transplantation (1084). In one study, insulin sensitivity, alpha and beta cell function, and beta cell reserve were studied in 14 hepatitis C-positive patients with liver transplants, who took tacrolimus or ciclosporin maintenance for 1 year (1085). The patients were matched for low prednisolone dosage (1.1 mg/day versus 1.3 mg/day), body mass index, lean body mass, and sex, and compared with eight controls. Insulin sensitivity and insulin secretory reserve were significantly different from controls, but there was no significant difference between ciclosporin and tacrolimus. 

Cyclodextrin-based drug delivery systems The hydrophilic cyclodextrins have been extensively )plied to enhance the oral bioavailabilily of steroids, cardiac glycosides, nonsteroidal anti-inflammatory drugs, barbiturates, antiepileptics, benzodiazepines, antidiabetics, vasodilators, etc. Delayed and prolonged release of diltiazem and molsidormine was achieved by their complexation with CD derivatives, modified release of nifedipine can be achieved by its complexation with 2-HP-P-CD fiirosemide and piretanide (loop diuretics) release can be modified after complexation with DM-P-CD. Prednisolone dosage forms can be optimized also by complex-formation with 2-HP-P-CD. 

Initial dosage varies from 5 to 60 mg/day. Prednisone is inactive and must be metabolized to prednisolone. This may be impaired in patients with liver disease. 

Hypersensitivity reactions Allergic reactions occur in approximately 33% of patients. They are more common at the start of treatment, and occur as generalized rashes or drug fever. Discontinue treatment and reinstitute at a low dosage such as 250 mg/day, with gradual increases. Administering prednisolone 20 mg/day for the first few weeks of penicillamine therapy reduces the severity of these reactions. Antihistamines may control pruritus. 

Glucocorticoids are commonly used in the treatment of patients with moderate to severe active inflammatory bowel disease. Active disease is commonly treated with an initial oral dosage of 40-60 mg/d of prednisone or prednisolone. Higher doses have not been shown to be more efficacious but have significantly greater adverse effects. Once a patient responds to initial therapy (usually within 1-2 weeks), the dosage is tapered to minimize development of adverse effects. In severely ill patients, the drugs are usually administered intravenously. 

Neomycin is administered orally for treatment of bacterial infections of cattle, sheep, pigs, goats, and poultry at a dosage of 10 mg/kg bw. It is also used as a feed additive for growth-promoting purposes. Neomycin is further available alone or in combination with other drugs such as oxytetracycline, oleandomycin, lincomycin, and prednisolone, in intramammary formulations for treatment of mastitis. There has been relatively little clinical use of neomycin parenterally in animals because of the compound s reported nephrotoxicity and ototoxicity. 

This report highlights the risk of cardiovascular adverse effects with short courses of glucocorticoid therapy in elderly patients with inflammatory bowel disease, even with rather low-dosage regimens. Acute myocardial infarction occurred in an old man with coronary insufficiency and giant cell arteritis after treatment with prednisolone (SEDA-10, 343) but could well have been coincidental. 

An 84-year-old woman with polymyalgia rheumatica and a 79-year-old woman with undifferentiated connective tissue disease and leukocytoclastic vasculitis were given prednisolone 20 mg/day with subsequent dosage reductions. The first patient developed a raised purpuric rash and lymphedema of the left leg within 5 months and the second developed large purple nodules on the soles of her feet and the backs of her hands accompanied by periorbital and peripheral edema. Skin biopsies showed Kaposi s sarcoma, and both patients had raised IgG antibody titers to human herpesvirus-8. 

Comparisons with oral glucocorticoids A meta-analysis of 21 studies in which 810 asthmatic children were treated with oral prednisolone (8 trials) and/or beclomethasone dipropionate, dosage range 200-900 micrograms/day (12 trials) has been reported. Significant suppression of growth occurred with oral glucocorticoids but not with beclomethasone dipropionate (145). 

Diabetes mellitus in a 36-year-old man with acute pancreatitis could not be controlled with continuous subcutaneous insulin infusion, even with doses up to 1800 U/ day, because of insulin resistance (168). Intravenous insulin by pump had to be stopped because of a catheter infection. The continuous subcutaneous infusion of freeze-dried insulin and the addition of aprotinin, a protease inhibitor, soluble dexamethasone or prednisolone, and intravenous immunoglobulin was ineffective. An implantable pump for intraperitoneal delivery established good regulation at a dosage of 30 U/day.

Anti-Inflammatory Effect of Different Dosage Schedules for Topical Administration of Prednisolone Acetate 1%... 

Management of the ocular aspects of Reiter s syndrome is directed toward control of inflammation.The uveitis can be fairly severe and resistant to therapy. In most instances such topical steroids as 1% prednisolone acetate or 0.1% dexamethasone are recommended. Dosage is variable but in severe cases should be administered initially every 1 to 2 hours and accompanied by such cycloplegic agents as 5% homatropine or 0.25% scopolamine two to three times daily. Aggressive treatment reduces formation of synechiae and subsequent secondary glaucoma. In patients who have severe uveitis, either sub-Tenon s capsule or oral steroids may be used in conjimction with topical management. 

In patients with history of ocular inflammation, 1% prednisolone acetate, one drop four times a day for 3 to 7 days, can be prescribed prophylactically after Nd YAG. Rarely, a patient without history of inflammation may present with flare or mild cells in the anterior chamber or CME after capsulotomy. This also should be treated with topical steroids in the same manner. Post-YAG elevated lOP can often be prevented by treating the eye with apra-clonidine (lopidine) or other aqueous suppressant topical medication. The recommended dosage is one drop applied before the capsulotomy and one drop immediately after the procedure. Because of the potential risk of a retinal break, patients should receive dilated fundus examinations postoperatively as part of the routine follow-up within 1 to 4 weeks of capsulotomy, or sooner if symptoms develop.
