Prednisone hydrochloride has anti-inflammatory, immunosuppressive and anti-allergic, anti-shock effects. Prednisone hydrochloride is a glucocorticoid. 1. Anti-inflammatory effect: glucocorticosteroids reduce and prevent tissue response to inflammation, thus reducing the manifestation of inflammation. 2. Immunosuppressive and anti-allergic effects: prevent or inhibit cell-mediated immune responses, delayed allergic reactions, reduce the number of T lymphocytes, monocytes eosinophils, reduce the binding capacity of immunoglobulin and cell surface receptors, and inhibit the synthesis and release of interleukin, thus reducing the conversion of T cells to lymphoblastoid cells and reducing the expansion of primary immune responses. 3. Anti-shock effect: glucocorticoids can counteract the stimulatory response of bacterial endotoxin to the body, reduce cellular damage, and play a role in protecting the body. Adverse reactions are common medical hyperadrenocorticism (full moon face, buffalo back, etc.), induced or aggravated infection, digestive discomfort (nausea, vomiting, etc.), osteoporosis, muscle atrophy, delayed wound healing, hypertension, elevated blood glucose and so on. Contraindications are severe psychosis and epilepsy, active peptic ulcer disease, hyperadrenocorticism, severe hypertension, diabetes mellitus, pregnant women, infections not controlled by antimicrobial drugs, allergy to glucocorticoids.
