Chelating agents generally refer to drugs that prevent chelation. They usually refer to one or more metal ions that combine with certain metal ions to prevent the absorption or release of metal ions, thus achieving the effect of preventing poisoning.
Chelating agents are mainly used to prevent drug precipitation, and usually include cationic chelating agents, anionic chelating agents, etc. The cationic chelating agents mainly include disodium ethylenediaminetetraacetate, deacetyllanosin hydrochloride injection, etc., while Anionic chelating agents mainly include aluminum hydroxide, magnesium trisilicate, etc. These chelating agents generally do not cause harm to the human body, but if patients use them for a long time, they may cause excessive metal ions in the body, leading to metal poisoning. Patients may experience nausea, vomiting, dizziness and other symptoms. It is recommended that patients use medication for treatment under the guidance of a doctor and should not blindly take medication on their own to avoid discomfort caused by improper medication.
In addition, patients need to pay attention to avoid eating foods containing metal ions, such as kelp, seaweed, etc., during the period of using chelating agents, so as not to affect the effect of the drug. At the same time, patients need to be careful to avoid eating spicy and irritating foods, such as chili peppers, Sichuan peppercorns, etc., during the use of chelating agents, so as not to affect the effect of drug treatment. If the patient develops symptoms of discomfort, it is recommended to seek medical treatment in time.
