preparation example Construction
[0042] A kind of preparation method that utilizes emulsification stirring tank and colloid mill to produce cefquinome sulfate injection, comprises the following steps: form according to the mode of following weight ratio: cefquinome sulfate 2.5% (g / ml); Stearin Aluminate 2.0% (g / v); Lecithin 1.0% (g / v); Vitamin E 0.2% (g / v); Injection grade ethyl oleate plus total volume.
[0043] 1. Add aluminum stearate to injection-grade ethyl oleate (80% v / v), and stir evenly in the emulsification mixing tank, heat the steam interlayer to 121°C, and keep stirring. After constant temperature for 30 minutes, use Cool the drinking water interlayer to room temperature, turn on the emulsifier on the emulsification tank, and emulsify for 30 minutes.
[0044] 2. Add cefquinome sulfate, lecithin, and vitamin E to (1), and turn on the emulsifier in the emulsification tank to emulsify for 30 minutes.
[0045] 3. Emulsify the emulsified medicinal solution in a colloid mill, grind it for 30 minutes, ...
Embodiment example 2
[0055] Form according to the following weight ratio: cefquinome sulfate 5% (g / ml); aluminum stearate 3% (g / v); lecithin 2% (g / v); vitamin E 0.5% ( g / v); injection grade ethyl oleate plus total volume.
[0056] 1. Add aluminum stearate to injection-grade ethyl oleate (80% v / v), and stir evenly in the emulsification mixing tank, heat the steam interlayer to 121°C, and keep stirring. After constant temperature for 30 minutes, use Cool the drinking water interlayer to room temperature, turn on the emulsifier on the emulsification tank, and emulsify for 30 minutes.
[0057] 2. Add cefquinome sulfate, lecithin, and vitamin E to (1), and turn on the emulsifier in the emulsification tank to emulsify for 30 minutes.
[0058] 3. Emulsify the emulsified medicinal solution in a colloid mill, grind it for 30 minutes, and then let it rest for 1 hour, then dissolve it with ethyl oleate to a sufficient amount, and recirculate it for emulsification and grinding for 30 minutes.
