Sulfonamides are the earliest type of artificially synthesized broad-spectrum antibacterial drugs used. The minimum effective concentration in the blood is 5 mg/100 ml, and 10-15 mg/100 ml is required for severe infections. They are effective against most Gram-positive bacteria and some Gram-negative bacteria. Sulfonamides exert their antibacterial effects by competing with PABA for dihydrofolate synthetase, hindering the synthesis of folate in sensitive bacteria. Sulfonamides have no effect on already synthesized folic acid, so the effect occurs slowly. Bacteria that can utilize exogenous folic acid are not sensitive to sulfonamides. Livestock and poultry cells can directly utilize folic acid, so they are not easily affected by sulfonamides blocking folic acid synthesis.

It is a vasodilator that can dilate coronary arteries and cerebral blood vessels, reduce myocardial oxygen consumption, improve microcirculation and resist platelet aggregation. It relaxes smooth muscles; it has a certain antihypertensive effect on normal and hypertensive animals; it has a significant dilating effect on coronary arteries, and can dilate normal and spasmodic coronary arteries. After intravenous injection of 30mg/kg, coronary blood flow can increase by 40% and vascular resistance can decrease by 29%; it can inhibit the release of 5-HT in platelets induced by thrombin.

This product is a flavonoid glycoside extracted from the root of Pueraria lobata or Pueraria lobata in the Leguminosae family. Animal experiments show that: 1. Effect on smooth muscle: Various total flavonoid compounds in Pueraria lobata have the effect of relaxing smooth muscle; 2. Effect on body temperature: artificial fever was induced by intravenous injection of expired typhoid vaccine in rabbit ears, and body temperature decreased after oral administration of 20% Pueraria lobata decoction or 20% ethanol infusion; 3. Effect on cardiovascular system: Pueraria lobata has a certain antihypertensive effect on normal and hypertensive animals. Pueraria lobata total flavonoids and puerarin have a significant effect of dilating coronary arteries, which can dilate normal and spasmodic coronary arteries. After intravenous injection of 30mg/Kg, coronary blood flow can increase by 40%, and vascular resistance can decrease by 29%. Puerarin can also inhibit the release of 5-HT in platelets induced by thrombin.

Effect on smooth muscle: Various total flavonoid compounds in Pueraria lobata have the effect of relaxing smooth muscle, while the contractile components may be substances such as choline, acetylcholine and carceline R. 2. Effect on body temperature: After artificial fever was caused by intravenous injection of expired typhoid vaccine into rabbit ears, the body temperature decreased after oral administration of 20% Pueraria lobata decoction or 20% ethanol infusion, and the effect of the infusion was particularly obvious. 3. Effect on the cardiovascular system: Pueraria lobata has a certain antihypertensive effect on normal and hypertensive animals. Pueraria lobata total flavonoids and puerarin have a significant effect of dilating coronary arteries, which can dilate normal and spasmodic coronary arteries. After intravenous injection of 30mg/Kg, coronary blood flow can increase by 40% and vascular resistance can decrease by 29%.
