Storage method

This product should be sealed in4 Store dry at ℃.

Synthesis method

p-Toluenesulfonamide is oxidized to p-carboxybenzenesulfonamide by sodium dichromate, and then used bromopropane Alkylation reaction, the resulting probenecid sodium is acidified with acetic acid to obtain probenecid.

Purpose

Anti-gout drugs. This product is an organic acid with strong fat solubility. It is excreted from the renal tubules and is easily absorbed back into the body. Therefore, in the presence of propanesulfonate, the operation of certain organic acids in the body’s renal tubules will be inhibited, reducing the excretion of other organic acids. Therefore, it is safe and effective for the treatment of chronic gout. It has no effect on the pain and inflammation of acute gout and is not suitable for acute gout.
