I need to prepare a suspension with co-trimoxazole.

Given that a suspension is requested, we suspect that it is intended for a child. In this case, the dose for 100 ml suspension: sulfamethoxazole 4 G and Trimethoprim 0.8 g.

As suspenders we can use the Excipiens Visceus without sugar of USP. The composition of this excipient is as follows: Xanthan gum 200 mg; Nasaccharinate 200 mg; Ksorbate 150 mg;   Citric acid Anh 100 mg; Sorbitol 4 G and freshly boiled purified water up to 100 ml. To improve the flavour we can add 200 mg of banana aroma.
