Sulfamethylphenazole potassium
Sulfamethylphenazole potassium (Sulfapyrazole potassium; Vesulong potassium) is a long-acting sulfonamide antibacterial agent. Sulfamethylphenazole potassium maintains effective chemotherapeutic blood concentrations through the slow release of free sulfonamide from a protein-binding reservoir and can be used in combination with antibiotics such as Terramycin for bovine hemorrhagic septicemia. Sulfamethylphenazole potassium exhibits moderate antimycobacterial activity against Mycobacterium tuberculosis H37Rv (MIC = 15.38 μg/mL) and inhibitory activity against CYP 2C9. Sulfamethylphenazole potassium can be used in studies related to tuberculosis and hemorrhagic septicemia.

体外実験
Sulfamethylphenazole potassium (compound 16c) moderately inhibits Mycobacterium tuberculosis H37Rv, with an MIC of 15.38 μg/mL[1].
Sulfamethylphenazole potassium (0.5 μM) inhibits CYP 2C9 by 45.0%[1].

体内実験
In a field survey of hemorrhagic septicemia in cattle/buffaloes in Punjab, Pakistan, Sulfamethylphenazole potassium combined with terramycin is preferred by 60% of veterinarians, while its single use is accepted by 30% of them. Moreover, it is only effective when administered in the early stage of the disease[3].

Animal Model:Female calves (Kalbinnen), 2-3 years of age[2]
-
Dosage:10 mL/100 kg; 20 mL/100 kg; 30 mL/100 kg
-
Administration:i.m.; single injection
-
Result:10 mL/100 kg dose group: twenty-four hours after dosing, the mean total sulfonamide in whole blood was 0.8 mg/100 mL and the mean free sulfonamide was 0.1 mg/100 mL. This free level was below the chemotherapeutically active threshold (0.2-0.3 mg/100 mL whole blood) and did not maintain an effective blood concentration.
20 mL/100 kg dose group: twenty-four hours after dosing, the mean total sulfonamide in whole blood was 2.1 mg/100 mL and the mean free sulfonamide was 0.3 mg/100 mL. This free level reached the active threshold and sustained a chemotherapeutically effective concentration for at least 24 hours.
30 mL/100 kg dose group: twenty-four hours after dosing, the mean total sulfonamide in whole blood was 4.2 mg/100 mL and the mean free sulfonamide was 0.7 mg/100 mL. This exceeded the active threshold and represented supratherapeutic exposure.
A single intramuscular injection of 20 mL of the 20% test sulfonamide solution per 100 kg body weight was the optimal dosage to maintain a chemotherapeutically active free sulfonamide level for at least 24 hours in cattle.
