Dexamethasone Acetate Tablets

Adrenal cortical hormone drugs have more significant anti-inflammatory, anti-allergic and anti-shock effects than prednisone, but have little effect on water and sodium retention and promoting potassium excretion, and have a strong inhibitory effect on the pituitary-adrenal gland. 1 Anti-inflammatory effect: This product can reduce and prevent tissue response to inflammation, thereby reducing the manifestations of inflammation. Hormones inhibit the accumulation of inflammatory cells, including macrophages and leukocytes at the site of inflammation, and inhibit phagocytosis, the release of lysosomal enzymes, and the synthesis and release of inflammatory chemical mediators. It can reduce and prevent tissue response to inflammation, thereby reducing the manifestations of inflammation. 2 Immunosuppressive effect: including preventing or inhibiting cell-mediated immune responses, delayed allergic reactions, reducing the number of T lymphocytes, monocytes, and eosinophils, reducing the ability of immunoglobulins to bind to cell surface receptors, and inhibiting the synthesis and release of interleukins, thereby reducing the transformation of T lymphocytes into lymphoblasts and reducing the expansion of primary immune responses. It can reduce the passage of immune complexes through the basement membrane and reduce the concentration of complement components and immunoglobulins.

Animal experiments have teratogenic effects, so the pros and cons should be weighed before use. If a nursing mother receives a large dose of the drug, she should not breastfeed to prevent the drug from being excreted through breast milk, causing adverse reactions such as infant growth inhibition and adrenal function inhibition. Precautions for the elderly: It is easy to cause hypertension. Elderly patients, especially postmenopausal women, are prone to osteoporosis when using it.
