| Questions And Answer | Back Directory | [Indications and Usage]
Betamethasone Sodium Phosphate, also called Bentelan, Betnesol, betamethasone phosphate, and celestone phosphate, is an adrenal cortex hormone, an isomer of dexamethasone with the same effects as prednisolone and dexamethasone.
It is mainly used against inflammation and allergies. Its effects are the same as those of dexamethasone, and its anti-inflammatory effects are stronger than dexamethasone, prednisone, and cortisone, with fewer side effects. It is used to treat active rheumatism, rheumatoid arthritis, lupus erythematosus, severe bronchial asthma, severe dermatitis, acute leukemia, allergic dermatitis, eczema, neurodermatitis, seborrheic dermatitis, pruritis, and comprehensively treat some infections.
| [Mechanisms of Action]
Betamethasone sodium phosphate has pharmacological effects in treating inflammation, rheumatism, allergies, and immunosuppressive conditions. Its anti-inflammatory effects are stronger than those of dexamethasone, triamcinolone, and hydrocortisone. It can reduce and prevent tissue response to inflammation, partly eliminating non-infectious inflammation caused by fever, redness, and swelling, thereby reducing the presence of swelling. The anti-inflammatory effects of 0.3 mg of betamethasone sodium phosphate are comparable to those of 0.75 mg of dexamethasone, 5 mg of prednisone, or 25 mg of cortisone. Its sodium retention effects are more than a hundred times those of cortisone. In case of primary adrenal hypofunction, together with corticosteroids, it can be used to replace treatment or prevention, or inhibit of cellular immune response, delay allergic reaction, and reduce the extension of the primary immune response, suitable for low renin and low aldosterone syndrome and orthodontic hypotension caused by autonomic neuropathy. | [Contraindications]
Not for use by those with a history of serious mental illness, active duodenum, gastric ulcers, recent gastrointestinal anastomosis, serious osteoporosis, pronounced diabetes, or serious high blood pressure, viruses which cannot be treated by antibiotics, bacterial of fungal infection, thrombophlebitis, or infectious skin diseases such as impetigo, tinea corporis, or tinea cruris. | [Category]
