Pharmacodynamic properties: Methylprednisolone Is a potent anti-inflammatory agent with the capacity to profoundly inhibit the immune system. Glucocorticoids primarily bind to and activate intracellular glucocorticoid receptors that being activated bind to promoter regions of DMA (which may activate or suppress transcription) and activate transcription factors that result in inactivation of genes through deacetylation of histones. Methylprednisolone influences the kidney and fluid & electrolyte balance, lipid,
protein, and carbohydrate metabolism, skeletal muscle, the cardiovascular system, the immune system, the nervous system, and the endocrine system.

Pharmacokinetic properties: The absolute bioavailability of Methylprednisclone is generally high (82% to 89%) following oral administration and rapidly absorbed and the maximum plasma concentration is achieved around 1.5 to 2.3 hours across doses following oral administration in normal healthy adults. Methylprednisolone is widely distributed into the tissues and its volume of distribution is 41-61.5 liter. It crosses the Wood-brain barrier and the placental barrier and is secreted in breast milk. The plasma protein binding of Methylprednisolone in humans is approximately 77%. Methylprednisolone is metabolized in the liver to inactive metabolites. No dosing adjustments are necessary for renal failure. Methylprednisolone is haemodializable.

The usual range is 2-48 mg daily in divided doses, depending on the specific disease being treated. 

As anti-inflammatory or immunosuppressive initial dosage: As anti-inflammatory or immunosuppressive, the initial dosage of Methylprednisolone tablets may vary from 4-48 mg 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 dirtied response, Methylprednisolone should be discontinued and the patient transferred to 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.

As anti-inflammatory or immunosuppressive maintenance dosage: 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 which will maintain an adequate clinical response is reached. It should be kept in mind that constant monitoring is needed in regard to drug dosage. If after long-term therapy the drug is to be stopped, it is recommended that it be withdrawn gradually rather than abruptly.

Multiple Sclerosis: In the treatment of acute exacerbations of multiple sclerosis, daily doses of 160 mg of Methylprednisolone for a week followed by 64 mg every other day for 1 month have been shown to be effective.

Methylprednisolone 4 mg tablet can be used to treat and to control severe allergy end dermatitis following the guideline listed below to minimize the steroid withdrawal syndromes:

• Day 1: 2 tablets before breakfast + 1 tablet after lunch + 1 tablet after dinner + 2 tablets at bedtime
• Day 2: 1 tablet before breakfast + 1 tablet after lunch + 1 tablet after dinner + 2 tablets at bedtime
• Day 3: 1 tablet before breakfast + 1 tablet after lunch + 1 tablet after dinner + 1 tablet at bedtime
• Day 4: 1 tablet before breakfast + 1 tablet after lunch + 1 tablet at bedtime
• Day 5: 1 tablet before breakfast + 1 tablet at bedtime
• Day 6: 1 tablet before breakfast

Alternate-day therapy (ADT): Alternate-day therapy is a corticosteroid dosing regimen in which twice the usual daily dose of corticoid is administered every other morning. The purpose of this mode of therapy is to provide the patient requiring long-term pharmacologic dose treatment with the beneficial effects of corticoids, white minimizing certain undesirable effects, including pituitary-adrenal suppression, Cushingoid stats, Corficoid withdrawal symptoms, and growth suppression in children.

The following should be kept in mind when considering alternate-day therapy:

• Basic principles and indications for corticosteroid therapy should be applied.
• Alternate-day therapy is a therapeutic technique primarily designed for pefienis in whom long-term pharmacologic corticoid therapy is anticipated.
• In less severe disease processes in which corticoid therapy is indicated, it may be possible to initiate treatment with alternate-day therapy. More severe disease state usually will require daily divided high dose therapy for initiai control of the disease process. The initial suppressive dose level should be continued until a satisfactory clinical response is obtained, usually four to ten days in the case of many allergic and collagen diseases.

Erythromycin, Clarithromycin, Phenobarbital, Phenytoin, Rifampin and Ketoconazole inhibit the metabolism of Methylprednisolone. Estrogens, including With control pills, can increase the effect of corticosteroids by 50%. Cyclosporin reduces the metabolism of Methylprednisolone. while Methylprednisolone reduces the metabolism of Cyclosporin. Methylprednisolone may increase or decrease the effect of blood thinners (e.g. Warfarin). For all these Interactions, the dose of Methylprednisolone may need to be lowered.

Systemic fungal infections arid known hypersensitivity to components.

Short courses of Methylprednisolone are usually well-tolerated with few, mild side effects. Long term, high doses of Methyiprednisoione may produce predictable and potentially serious side effects. Whenever possible, the lowest effective doses of Methylprednisolone should be used for the shortest length of time to minimize side effects. Alternate day dosing also can help reduce side effects. Side effects of Methylprednisolone and other corticosteroids range from mild annoyances to serious irreversible bodily damage. Side effects include fluid retention, weight gain, high blood pressure, potassium loss, headache, muscle weakness, hair growth on the face, glaucoma, cataracts, peptic ulceration, growth retardation in children, convulsions, and psychic disturbances including depression, euphoria, insomnia etc. Prolonged use of Methylprednisolone can depress the ability of the body's adrenal glands to produce corticosteroids. Abruptly stopping Methylprednisolone in these individuals can cause symptoms of corticosteroid insufficiency, with accompanying nausea, vomiting, and even shock. Therefore, withdrawal of Methylprednisolone usually is accomplished by gradually lowering the dose. Gradually tapering Methylprednisolone not only minimizes the symptoms of corticosteroid insufficiency, it also reduces the risk of an abrupt flare of the disease being treated.

Pregnancy category C. Dregs should be given only if the potential benefit justifies the potential risk te the foetus. Mefhyiprednisofone has not been adequately evaluated in nursing mothers.

Adrenocortical insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted. Since mineralocorticoid secretion may be impaired, salt and/or a mineralocorticoid should be administered concurrently. There is an enhanced effect of corticosteroids on patients with hypothyroidism and in those with cirrhosis. Corticosteroids should be used cautiously in patients with ocular herpes simplex because of possible corneal perforation. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The growth and development of infants and children on prolonged corticosteroid therapy should be carefully observed.

Report of acute toxicity and/or death following an overdose of glucocorticoid ere rare. No specific antidote is available; treatment is supportive and symptomatic. Serum electrolytes should be monitored.
