Rifamycin SV is a derivative of antibiotic rifamycin B (the natural fermentation product of S. mediterranei broths). The primary target of rifampicin on whole bacteria is the synthesis of RNA. Rifamycin belongs to the ansamycin class of antibacterial drugs and acts by inhibiting the beta subunit of the bacterial DNA-dependent RNA polymerase, blocking one of the steps in DNA transcription. This results in inhibition of bacterial synthesis and consequently growth of bacteria. Rifampicin exhibits bactericidal activity on Gram-positive and Gram-negative bacteria and on mycobacteria. Rifamycin SV MMX® (AEMCOLO), a non-absorbable rifamycin antibiotic formulated using the multi-matrix system, was designed to exhibit its pharmacological action on the distal small intestine and colon. AEMCOLO is indicated for the treatment of travelers’ diarrhea (TD) caused by non-invasive strains of Escherichia coli in adults.

Sucrose octaacetate is an acetylated derivative of sucrose. It can be used as a bitter additive, a denaturant for alcohol, a soaker for paper, as well as an insecticide, plasticizer for cellulosic&synthetic resin. It also can be used as an additive for paint and children's toys, etc. It can prevent mice or children from biting or tasting the goods because of its extreme bitter taste. Sucrose octaacetate was determined by the EPA to be usable as an inert ingredient in pesticides due to its low toxicity
