Product Description

Biological Activity

Secnidazole (Flagentyl) is a nitroimidazole anti-infective. Secnidazole (Flagentyl) is effective in the treatment of dientamoebiasis. Secnidazole (Flagentyl) has also been tested against Atopobium vaginae. An MIC range for secnidazole (Flagentyl) is 4-128 mg/L. The MIC50 for secnidazole (Flagentyl) is 16 mg/L. The MIC90 for secnidazole (Flagentyl) is 64 mg/L. Secnidazole (Flagentyl) is highly effective in achieving parasitologic. [1][2][3]

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) ×  mouse Km(3)  = 11.2 mg/kg
