Acetate, or medicinal charcoal, is an intestinal adsorbent that adsorbs toxins, gases, electrolytes, creatinine, uric acid, etc. from the intestine so that these substances no longer enter the bloodstream or enter the body’s circulation. It is mainly used for detoxification of the intestinal tract, decongestion, hyperkalemia, and renal insufficiency, etc. Its usage is 3-10 tablets 3 times a day for adults. When used for detoxification, it can be used together with intestinal laxatives, which have the effect of promoting the elimination of toxic substances; when used for decongestion, it is important to control the intake of easily fermented gas-producing foods. It can also be used together with drugs that adsorb gas or promote intestinal peristalsis, such as trimethoprim maleate, such as simethicone oil.
