151-73-5 Usage
Description
Betamethasone 21-phosphate disodium, also known as Betamethasone 21-Phosphate Disodium Salt, is an organic sodium salt that is the disodium salt of betamethasone phosphate. It is a glucocorticoid steroid with anti-inflammatory and immunosuppressive properties. It appears as a white or almost white powder and is very hygroscopic. It falls under the category of toxic substances.
Uses
Used in Pharmaceutical Industry:
Betamethasone 21-phosphate disodium is used as an anti-inflammatory agent for its potent anti-inflammatory and immunosuppressive properties. It is particularly effective in treating conditions such as asthma and itching.
Used in Nasal Applications:
Betamethasone 21-phosphate disodium is used as a nasal anti-inflammatory agent to alleviate inflammation and swelling in the nasal passages, providing relief from nasal congestion and other related symptoms.
Used in Ophthalmic Applications:
In the field of ophthalmology, Betamethasone 21-phosphate disodium is used as an anti-inflammatory agent to treat eye conditions such as uveitis, iritis, and other inflammatory eye disorders.
Used in Oral Applications:
Betamethasone 21-phosphate disodium is used as an oral anti-inflammatory and immunosuppressive agent to manage various inflammatory and autoimmune conditions, including rheumatoid arthritis, lupus, and other similar diseases.
Used in Parenteral Applications:
As a parenteral anti-inflammatory and immunosuppressive agent, Betamethasone 21-phosphate disodium is administered through injections or infusions to treat severe inflammation, autoimmune disorders, and other conditions that require systemic treatment.
Brand Name:
Celestone (Schering) is a well-known brand name for Betamethasone 21-phosphate disodium, which is widely used in the treatment of various inflammatory and immunological conditions.
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.

Check Digit Verification of cas no
The CAS Registry Mumber 151-73-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151-73:
(5*1)+(4*5)+(3*1)+(2*7)+(1*3)=45
45 % 10 = 5
So 151-73-5 is a valid CAS Registry Number.
