Taking 2 tablets of compound aminoglutethimide at a time does not cause serious damage, simply because the main ingredient, acetaminophen, is a non-steroidal anti-inflammatory drug that may cause gastrointestinal discomfort and, in the most severe cases, acute gastritis. The main component of acetaminophen, acetaminophen, is mainly metabolized in the liver by combining with sulfuric acid or glucuronic acid, and a small portion is metabolized by the cytochrome P450 system into hydroxylates that are toxic to the liver, and these hydroxylates are mainly inactivated by reduced glutathione in the liver, which may cause liver necrosis if the bone reduced glutathione in the liver is depleted. If you take 2 tablets of compound aminoglutethimide tablets at one time, the intake of acetaminophen is about 500mg, and if you take it 10 times a day or even more, the intake of acetaminophen in a day can reach more than 10g, and liver necrosis is very likely to occur in this case. Therefore, cold medicine should not be taken casually more than once, but strictly in accordance with the dosage on the instructions.
