are metronidazole to child made in a special way? Should something be added for stability?

I don't think Dar special attention should be given to process metronidazole in suppositories outside the deetjessize. Metronidazole is treacherous in the sense that it seems a fine powder but not. So, prior to milling with electric coffee grinder. I think Metronidazole is easily moisten by melted suppository mass. If not a few drops   add Arlacel.
