How to make oral suspension from a 250mg, metronidazole pill

This is a formula for metronidazole:

250 mg. tablet + 10 ml (cc) water (or, syrpalta, grape flavored)

This will be at 25 mg/ml concentration

Example: 250 gram bird - Dose 20 mg/kg (the 20 mg/kg is a set standard for this medicine): Weight is converted to kilograms .25 kg x 20 mg/kg divided by 25 mg/ml equals a dose of 0.2 ml (cc).

I use bottled water, room temp, and refrigerate.. It is extremely important that the pill be pounded into a powder and then put in the water. ALWAYS shake the bottle strongly to get it mixed well, and draw the medicine immediately after shaking.

This is from my vet. Some weights/dosage: 175 grams - .14 cc; 275 grams - .22 cc; 400 grams - .32 cc.
