Efficacy & effects

View approved original text

This medication is used to adsorb gases produced by diarrhea and abnormal fermentation in the gastrointestinal tract. It is also usefully employed as an emergency detoxifier in cases of poisoning from drugs or chemicals. However, the adsorptive effect on certain substances such as cyanide compounds, alcohol, hydrocarbon solvents, some metal salts and heavy metals, and inorganic acids is limited. Therefore, in the event of poisoning, this medicine can help absorb harmful substances to protect the body. Due to these characteristics, it is effectively used for safe recovery from gastrointestinal issues and toxic substances.
