Prednisolone Sodium Phosphate is a corticosteroid medicine that is used to reduce inflammation and suppress the immune response. Each dose is equivalent to 5 mg of Prednisolone. It is commonly prescribed for children to treat a variety of conditions where inflammation or an overactive immune system is involved. It works by mimicking the action of natural steroid hormones produced by the adrenal glands, helping to control swelling, allergic reactions, and other immune-related responses.
