Prednisolone decreases inflammation by inhibition of migration of polymorphonuclear leukocytes and reversal of increased capillary permeability. It suppresses the immune system by reducing the activity and production of the lymphocytes and eosinophils.
The initial dosage of Prednisolone may vary from 5 mg to 60 mg daily depending on the disorder being treated. Divided daily dosage is usually used.
The appropriate individual dose must be determined by trial and error and must be re-evaluated regularly according to activity of the disease.
In general, initial dosage shall be maintained or adjusted until the anticipated response is observed. The dose should be gradually reduced until the lowest dose, which will maintain an adequate clinical response is reached.
During prolonged therapy, dosage may need to be temporarily increased during periods of stress or during exacerbations of the disease. When the drug is to be stopped, it must be withdrawn gradually and not abruptly.
Intermittent dosage regimen: A single dose of Prednisolone in the morning on alternate days or at longer intervals is acceptable therapy for some patients. When this regimen is practical, the degree of pituitary-adrenal suppression can be minimized.
Use in children: Corticosteroids cause growth retardation in infancy, childhood and adolescence, which may be irreversible. Treatment should be administered where possible as a single dose on alternate days.
Specific dosage guidelines-
Allergic and skin disorders: initial doses of 5-15 mg daily are commonly adequate.
Collagenosis: Initial doses of 20-30 mg daily are frequently effective. Those with more severe symptoms may require higher doses.
Rheumatoid arthritis: The usual initial dose is 10-15 mg daily. The lowest daily maintenance dose compatible with tolerable symptomatic relief is recommended.
Blood disorders and lymphoma: An initial daily dose of 15-60 mg is often necessary with reduction after an adequate clinical or haematological response. Higher doses may be necessary to induce remission in acute leukaemia.
