PREDNISOLONE SODIUM SUCCINATE
For more information refer to the monograph: Glucocorticoids, General Information or to the manufacturer’s product information for veterinary labeled products.
Note: Although separate entities, prednisone is rapidly converted by the liver in vivo to prednisolone. Except for patients in frank hepatic failure, the drugs can, for all intents, be considered equivalent.
Chemistry – Prednisolone and prednisone are synthetic glucocorticoids. Prednisolone and prednisolone acetate occur as odorless, white to practically white, crystalline powders. Prednisolone is very slightly soluble in water and slightly soluble in alcohol. The acetate ester is practically insoluble in water and slightly soluble in alcohol. The sodium succinate ester is highly water soluble. Prednisolone is also known as deltahydrocortisone or metacortandralone .
Prednisone occurs as an odorless, white to practically white, crystalline powder. Prednisone is very slightly soluble in water and slightly soluble in alcohol. Prednisone is also known as deltacortisone or deltadehydrocortisone .
Storage/Stability/Compatibility – Prednisolone and prednisone tablets should be stored in well-closed containers. All prednisone and prednisolone products should be stored at temperatures less than 40°, and preferably between 15-30°C; avoid freezing liquid products. Do not autoclave. Oral liquid preparations of prednisone should be stored in tight containers.
Prednisolone sodium succinate should be stored at room temperature and protected from light (store in carton). After reconstitution, the product is recommended to be used immediately and not stored.
Little data appears to be available regarding the compatibility of prednisolone sodium succinate injection (Solu-Delta Cortef® — Upjohn) with other products. A related compound, prednisolone sodium phosphate is reportedly compatible with the following drugs/solutions: ascorbic acid injection, cephalothin sodium, cytarabine, erythromycin lactobionate, fluorouracil, heparin sodium, methicillin sodium, penicillin G potassium/sodium, tetracycline HCl and vitamin B-Complex with C. It is reportedly incompatible with: calcium gluconate/gluceptate, dimenhydrinate, metaraminol bitartrate, methotrexate sodium, prochlorperazine edisylate, polymyxin B sulfate, promazine HCl, and promethazine. Compatibility is dependent upon factors such as pH, concentration, temperature and diluents used. It is suggested to consult specialized references for more specific information (e.g., Handbook on Injectable Drugs by Trissel; see bibliography).
For adjunctive therapy of COPD:
a) Prednisolone: Initially, 600 – 800 mg IM or PO in a 450 kg horse. May be possible to decrease dose and go to alternate day dosing. Doses as low as 200 mg every other day may be effective. (Beech 1987a)
For glucocorticoid effects:
a) Prednisolone sodium succinate: 0.25 – 1 mg/kg IV, Predniso(lo)ne tablets 0.25 – 1 mg/kg PO; Prednisolone acetate: 0.25 – 1.0 mg/kg IM or 10 – 25 mg subconjunctivally. (Robinson 1987)
a) For treatment of heatstroke: 1mg / 3 kg body weight (Schmidt, 1986).
