Methotrexate is used as a disease-modifying treatment for some autoimmune diseases, including rheumatoid arthritis, juvenile dermatomyositis, psoriasis, psoriatic arthritis, lupus, sarcoidosis, Crohn's disease (although a recent review has raised the point that it is fairly underused in Crohn's disease), eczema and many forms of vasculitis. Although originally designed as a chemotherapy drug (using high doses), in low doses, methotrexate is a generally safe and well tolerated drug in the treatment of certain autoimmune diseases. Because of its effectiveness, low-dose methotrexate is now first-line therapy for the treatment of rheumatoid arthritis. Weekly doses are beneficial for 12 to 52 weeks duration therapy, although discontinuation rates are as high as 16% due to adverse effects. Although methotrexate for autoimmune diseases is taken in lower doses than it is for cancer, side effects such as hair loss, nausea, headaches, and skin pigmentation are still common. Use of low doses of methotrexate together with NSAIDS such as aspirin or paracetamol is relatively safe in people being treated for rheumatoid arthritis, if adequate monitoring is done.

Methotrexat (Amethopterin) disodium is an antimetabolite and antifolate that inhibits dihydrofolate reductase, thereby preventing the conversion of folic acid to tetrahydrofolate and inhibiting DNA synthesis.
Function of Methotrexat Disodium Salt
Methotrexat disodium is also an immunosuppressant and antitumor agent used in rheumatoid arthritis and in studies of various cancers (e.g., acute lymphocytic leukemia).
Application of Methotrexate Disodium Salt
Methotrexat disodium is also an immunosuppressant and antitumor agent used in rheumatoid arthritis and in the study of various cancers (e.g., acute lymphoblastic leukemia).
Liquid ammonia, also known as anhydrous ammonia, is colorless liquid and has a strong pungent odor. As an important chemical raw material, ammonia is usually pressurized or cooled to obtain liquid ammonia in order to facilitate transportation and storage. Ammonia soluble in water, soluble in water to form ammonium ion NH4+, hydroxide ion OH-, is an alkaline alkaline solution. Liquid ammonia is mostly stored in pressure cylinders or steel tanks, and can not coexist with acetaldehyde, acrolein, boron and other substances. Liquid ammonia is widely used in industry, is corrosive and volatile, so its chemical accident rate is very high.
