PREDNISOLONE SODIUM PHOSPHATE ODT

Prednisolone sodium phosphate orally disintegrating tablets are a sodium salt of the phosphoester of the glucocorticoid prednisolone. Glucocorticoids are adrenocortical steroids, both naturally occurring and synthetic, which are readily absorbed from the gastrointestinal tract. Prednisolone sodium phosphate occurs as white or slightly yellow, friable granules or powder. It is freely soluble in water; soluble in methanol; slightly soluble in alcohol and in chloroform; and very slightly soluble in acetone and in dioxane. The chemical name of prednisolone sodium phosphate is pregna-1, 4-diene-3, 20-dione, 11, 17-dihydroxy-21-(phosphonooxy)-, disodium salt, (11ß)-. The empirical formula is C 21 H 27 Na 2 O 8 P; the molecular weight is 484.39. Its chemical structure is: Each orally disintegrating tablet also contains the following inactive ingredients: citric acid, colloidal silicon dioxide, crospovidone, grape flavor, hypromellose, magnesium stearate, mannitol, methacrylate copolymer, microcrystalline cellulose, sodium bicarbonate, sucralose, and sucrose. 5

DOSAGE & ADMINISTRATION Individualize dosing based on disease severity and patient response: Initial Dose: 10 mg to 60 mg of prednisolone (as 13.4 mg to 80.6 mg of prednisolone sodium phosphate) (2) Maintenance Dose: Use lowest dosage that will maintain an adequate clinical response (2) Discontinuation: Withdraw gradually if discontinuing long-term or high-dose therapy (2) Take with food to avoid gastrointestinal (GI) irritation (2) DO NOT BREAK OR USE PARTIAL PREDNISOLONE SODIUM PHOSPHATE ORALLY DISINTEGRATING TABLETS. USE AN APPROPRIATE FORMULATION OF PREDNISOLONE IF INDICATED DOSE CANNOT BE OBTAINED USING PREDNISOLONE SODIUM PHOSPHATE ORALLY DISINTEGRATING TABLETS. 2.1 Recommended Dosing Dosage of Prednisolone Sodium Phosphate Orally Disintegrating Tablets should be individualized according to the severity of the disease and the response of the patient. For pediatric patients, the recommended dosage should be governed by the same considerations rather than strict adherence to the ratio indicated by age or body weight. Do not break or use partial Prednisolone Sodium Phosphate Orally Disintegrating Tablets. Use an appropriate formulation of prednisolone if indicated dose cannot be obtained using Prednisolone Sodium Phosphate Orally Disintegrating Tablets. This may become important in the treatment of conditions that require tapering doses that cannot be adequately accommodated by Prednisolone Sodium Phosphate Orally Disintegrating Tablets, e.g., tapering the dose below 10 mg. The initial dose of Prednisolone Sodium Phosphate Orally Disintegrating Tablets may vary from 10 to 60 mg (prednisolone base) per day, depending on the specific disease entity being treated. In situations of less severity, lower doses will generally suffice while in selected patients higher initial doses may be required. The initial dosage should be maintained or adjusted until a satisfactory response is noted. If after a reasonable period of time, there is a lack of satisfactory clinical response, Prednisolone Sodium Phosphate should be discontinued and the patient placed on other appropriate therapy. IT SHOULD BE EMPHASIZED THAT DOSAGE REQUIREMENTS ARE VARIABLE AND MUST BE INDIVIDUALIZED ON THE BASIS OF THE DISEASE UNDER TREATMENT AND THE RESPONSE OF THE PATIENT. After a favorable response is noted, the proper maintenance dosage should be determined by decreasing the initial drug dosage in small decrements at appropriate time intervals until the lowest dosage that will maintain an adequate clinical response is reached. It should be kept in mind that constant monitoring is needed in regard to drug dosage. Included in the situations which may make dosage adjustments necessary are changes in clinical status secondary to remissions or exacerbations in the disease process, the patient's individual drug responsiveness, and the effect of patient exposure to stressful situations not directly related to the disease entity under treatment; in this latter situation it may be necessary to increase the dosage of Prednisolone Sodium Phosphate Orally Disintegrating Tablets for a period of time consistent with the patient's condition. If after long term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually rather than abruptly. Prednisolone Sodium Phosphate Orally Disintegrating Tablets are packaged in a blister. Patients should be instructed not to remove the tablet from the blister until just prior to dosing. The blister pack should then be peeled open, and the orally disintegrating tablet placed on the tongue, where tablets may be swallowed whole as any conventional tablet, or allowed to dissolve in the mouth, with or without the assistance of water. Orally disintegrating tablet dosage forms are friable and are not intended to be cut, split, or broken. Multiple Sclerosis In the treatment of acute exacerbations of multiple sclerosis, daily doses of 200 mg of prednisolone for a week followed by 80 mg every other day for one month have been shown to be effective. Pediatric In pediatric patients, the initial dose of Prednisolone Sodium Phosphate may vary depending on the specific disease entity being treated. The range of initial doses is 0.14 to 2 mg/kg/day in three or four divided doses (4 to 60 mg/m 2 bsa/day). Nephrotic Syndrome The standard regimen used to treat nephrotic syndrome in pediatric patients is 60 mg/m 2 /day given in three divided doses for 4 weeks, followed by 4 weeks of single dose alternate-day therapy at 40 mg/m 2 /day. Asthma The National Heart, Lung, and Blood Institute (NHLBI) recommended dosing for systemic prednisone, prednisolone or methylprednisolone in children whose asthma is uncontrolled by inhaled corticosteroids and long-acting bronchodilators is 1-2 mg/kg/day in single or divided doses. It is further recommended that short course, or "burst" therapy, be continued until a child achieves a peak expiratory flow rate of 80% of his or her personal best or symptoms resolve. This usually requires 3 to 10 days of treatment, although it can take longer. There is no evidence that tapering the dose after improvement will prevent a relapse. 2.2 Recommended Monitoring Blood pressure, body weight, routine laboratory studies, including serum potassium and fasting blood glucose, should be obtained at regular intervals during prolonged therapy. Appropriate diagnostic studies should be performed in patients with known or suspected peptic ulcer disease and in patients at risk for reactivation of latent tuberculosis infections. 2.3 Corticosteroid Comparison Chart For the purpose of comparison, one 10 mg prednisolone sodium phosphate orally disintegrating tablet (13.4 mg prednisolone sodium phosphate) is equivalent to the following milligram dosage of the various glucocorticoids: Betamethasone 1.75 mg Paramethasone 4 mg Cortisone 50 mg Prednisolone 10 mg Dexamethasone 1.75 mg Prednisone 10 mg Hydrocortisone 40 mg Triamcinolone 8 mg Methylprednisolone 8 mg These dose relationships apply only to oral or intravenous administration of these compounds. When these substances or their derivatives are injected intramuscularly or into joint spaces, their relative properties may be greatly altered.

Aminoglutethimide : Aminoglutethimide may lead to loss of corticosteroid-induced adrenal suppression. Amphotericin B : There have been cases reported in which concomitant use of Amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure (see also Potassium depleting agents). Anticholinesterase agents : Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy. Anticoagulant agents : Co-administration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Therefore, coagulation indices should be monitored frequently to maintain the desired anticoagulant effect. Antidiabetic Agents : Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required. Antitubercular drugs : Serum concentrations of isoniazid may be decreased. CYP 3A4 inducers (e.g. barbiturates, phenytoin, carbamazepine, and rifampin) : Drugs such as barbiturates, phenytoin, ephedrine, and rifampin, which induce hepatic microsomal drug metabolizing enzyme activity may enhance metabolism of prednisolone and require that the dosage of Prednisolone Sodium Phosphate be increased. CYP 3A4 inhibitors (e.g., ketoconazole, macrolide antibiotics) : Ketoconazole has been reported to decrease the metabolism of certain corticosteroids by up to 60% leading to an increased risk of corticosteroid side effects. Cholestyramine : Cholestyramine may increase the clearance of corticosteroids. Cyclosporine : Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with this concurrent use. Digitalis : Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia. Estrogens, including oral contraceptives : Estrogens may decrease the hepatic metabolism of certain corticosteroids thereby increasing their effect. NSAIDS, including aspirin and salicylates : Concomitant use of aspirin or other non-steroidal anti-inflammatory agents and corticosteroids increases the risk of gastrointestinal side effects. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids. Potassium-depleting agents (e.g., diuretics, Amphotericin B) : When corticosteroids are administered concomitantly with potassium-depleting agents, patients should be observed closely for development of hypokalemia. Skin Tests : Corticosteroids may suppress reactions to skin tests. Toxoids and live or inactivated Vaccines : Due to inhibition of antibody response, patients on prolonged corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines. Anticoagulant Agents: May enhance or diminish anticoagulant effects. Monitor coagulation indices. (7) Antidiabetic Agents: May increase blood glucose concentrations. Dose adjustments of antidiabetic agents may be required. (7) CYP 3A4 inducers and inhibitors: May, respectively, increase or decrease clearance of corticosteroids, necessitating dose adjustment. (7) Cyclosporine: Increase in activity of both, cyclosporine and corticosteroid when administered concurrently. Convulsions have been reported with concurrent use. (7) NSAIDS including aspirin and salicylates: Increased risk of gastrointestinal side effects. (7)
