Storage method

This product should be sealed and stored in a cool, dry place.

Synthesis method

From 2, 4-dichlorobenzoic acid (see 12740) through chlorosulfonation, ammoniation and acidification to obtain 2, 4-dichloro-5-Sulfamoyl benzoic acid is then condensed with furfurylamine to produce furosemide.

Purpose

This product has a strong but short-lived diuretic effect. It is a powerful diuretic and is used to treat edema caused by heart, liver, kidney and other diseases. , especially in cases where base diuretics are ineffective; it can be used to treat acute pulmonary edema, cerebral edema, acute renal failure, hypertension and other diseases; combined with rehydration, this product can promote the non-excretion of poisons.
