This product is one of the ingredients of the Chinese medicine bezoar. As an endogenous amino acid in the human body, this product is a central inhibitory transmitter that can regulate the excitability of nerve tissue and body temperature. Therefore, it has antipyretic, sedative, analgesic, anti-inflammatory, anti-rheumatic, and anticonvulsant effects. In addition, it can improve the body's nonspecific immune function.

1. Effect on water and electrolyte excretion: diuretic effect, increased excretion of urinary sodium, potassium, chloride, phosphorus and magnesium ions, and reduced excretion of urinary calcium. The mechanism of action of this type of drug is mainly to inhibit the reabsorption of sodium chloride by the distal tubule anterior segment and the proximal tubule (less severe), thereby increasing the Na-K exchange of the distal tubule and the collecting duct, and increasing K+ secretion. Its mechanism of action is not yet fully understood. This type of drug can inhibit carbonic anhydrase activity to varying degrees, so it can explain its effect on the proximal tubule. This type of drug can also inhibit phosphodiesterase activity, reduce the renal tubular uptake of fatty acids and mitochondrial oxygen consumption, thereby inhibiting the active reabsorption of Na and Cl- by the renal tubule. ② Antihypertensive effect. In addition to the diuretic and sodium excretion effects, there may be extrarenal mechanisms involved in blood pressure reduction, which may be to increase the excretion of Na in the gastrointestinal tract. 2. Impact on renal hemodynamics and glomerular filtration function: Due to the reduced reabsorption of water and Na by the renal tubules, the increased pressure in the renal tubules, and the increased water and Na flowing through the distal convoluted tubules, the macula densa is stimulated through the tubular-glomerular reflex, which increases the secretion of renin and angiotensin in the kidney, causing renal vasoconstriction, a decrease in renal blood flow, contraction of the glomerular afferent and efferent arterioles, and a decrease in the glomerular filtration rate.

Anticholinergic drugs, with atropine and papaverine-like effects. This product has the effects of relieving spasms and resisting gastric acid secretion, and can make gastrointestinal function tend to normal; this product can also inhibit sweat gland secretion, so it can be used to treat hyperhidrosis.

Broad-spectrum antiviral drug. It has the effect of inhibiting the growth of multiple viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. in vitro, and its mechanism is not fully understood. After entering the virus-infected cells, the drug is rapidly phosphorylated, and its product acts as a competitive inhibitor of viral synthase, inhibiting inosine monophosphate dehydrogenase, influenza virus RNA polymerase and mRNA guanosine transferase, thereby causing a decrease in intracellular guanosine triphosphate, impairing viral RNA and protein synthesis, and inhibiting viral replication and transmission. It may also have an immune effect and neutralizing antibody effect on respiratory syncytial virus.
