I am looking for a formula to prepare diazepam 1mg/ml, should be administered via a probe to a child of 3 years

Diazepam 100 mg propylene glycol 10 g ethanol 20 ml   Citric acid monohydr 250 mg Sorbitol 70% not crystallizable   65g Aqua Conservans up to 100 ml Possibly raspberry essence 450 mg

The viscosity Is too high then you can reduce the amount of sorbitol   70% and Replaced with water. This can give rise to precipitation. Which is possible to absorb with additional   small amounts (50 mg) to add citric acid???
