Drug Function and Efficacy

This product has two thiol groups, which can be complexed with metals to form non-toxic complexes that are not easily dissociated and excreted in urine. Dithiol compounds have a greater affinity for metals and can capture metals that have been bound to enzymes, thereby restoring enzyme activity. Since the complexes formed by dithiol drugs with metals still have a certain degree of dissociation, if the excretion is slow, the dissociated dithiol compounds can be quickly oxidized, and the free metals can still produce poisoning. Therefore, this product needs to be repeatedly administered in sufficient amounts in case of metal poisoning.

This ingredient has been used in drugs with the following functions (note: it does not mean that the ingredient itself has the following health functions)
