Abstract:
1. An aqueous rifampicin suspension comprising from about 1 to about 5 percent by weight rifampicin with an average particle size less than about 10 μm; from about 0.1 to about 0.5 percent by weight of xanthan gum; from about 0.01 to about 2 percent by weight of at least one antifoaming agent; from about 0.001 to about 0.5 percent by weight of at least one wetting agent; a liquid phase with an absolute density difference of less than about 0.05 g/ml from the particulate rifampicin; the suspension being further characterized by a relative standard deviation of less than about 6% when tested according to the Centrifugation Test Method.
