Introduction
Under normal circumstances, dexamethasone sodium phosphate injection, as a glucocorticoid agent, has main effects including anti-inflammatory, anti-allergic, anti-shock actions, suppression of immune responses, and relief of cerebral edema. It should be used under the guidance of a physician according to specific medical conditions. When using this injection, dosage and duration of treatment must strictly follow medical instructions; patients should avoid adjusting the dose or discontinuing the medication without authorization.
Generally, as a glucocorticoid medication, dexamethasone sodium phosphate injection mainly functions to reduce inflammation, alleviate allergic reactions, combat shock, suppress immune responses, and relieve cerebral edema. It must be used according to the specific condition under a doctor's guidance. Detailed explanations are as follows:
1. Anti-inflammatory: This injection can inhibit inflammatory cells from gathering at the inflamed area and reduce the release of inflammatory mediators, thus alleviating inflammatory responses. It is suitable for inflammatory diseases such as rheumatoid arthritis, tendon sheath inflammation, and severe dermatitis, helping relieve symptoms such as redness, swelling, and pain.
2. Anti-allergic: It can inhibit the release of chemical substances such as histamine during allergic reactions, blocking the stimulation of allergic mediators on tissues. It is suitable for severe allergic conditions such as anaphylactic shock, allergic rhinitis, and urticaria, rapidly alleviating allergy symptoms such as skin itching and breathing difficulties.
3. Anti-shock: In critical conditions such as septic shock or traumatic shock, this medication can stabilize lysosomal membranes, reduce the release of shock factors, improve microcirculation, enhance the body's tolerance to shock, and assist in correcting the shock state.
4. Immunosuppression: It can suppress immune responses and reduce immune cell activity. It is suitable for autoimmune diseases and post-organ transplantation to prevent or alleviate immune rejection reactions.
5. Relief of cerebral edema: It can reduce inflammation and edema in brain tissue, lower intracranial pressure, and is applicable for cerebral edema caused by brain tumors, brain trauma, encephalitis, etc., alleviating related symptoms such as headache, vomiting, and impaired consciousness.
When using this injection, strictly follow medical instructions to control dosage and duration of treatment, and avoid adjusting the dosage or stopping the medication without authorization to prevent adverse reactions. Additionally, attention should be paid to drug contraindications, such as not using it in patients allergic to glucocorticoids.
