Function of Prednisolone
Prednisolone is an adrenal cortex hormone drug. Super-physiological glucocorticoids have a variety of pharmacological effects such as anti-inflammatory, anti-allergic and immune suppression.
1. Anti-inflammatory effects: glucocorticoids reduce and prevent tissue response to inflammation, thereby reducing the performance of inflammation.
2. Immunosuppressive effects: prevent or inhibit cell-mediated immune responses, delayed allergic reactions, reduce the number of T lymphocytes and monocyte eosinophils, reduce the binding ability of immunoglobulins and cell surface receptors, and inhibit interleukins Synthesis and release, thereby reducing the transformation of T cells to lymphoblasts, and reducing the expansion of the primary immune response.
3. Anti-toxic and anti-shock effects: Glucocorticoids can counteract the stimulating response of bacterial endotoxins to the body, reduce cell damage, and play a role in protecting the body.
