When acid poisoning is handled with milk of magnesia, the alkaline motion of milk of magnesia neutralizes the results of acid poisoning.
Particularly, the interactions of chelating drugs with vital and xenobiotic metals, lessening and oxidizing agents, natural and synthetic drugs or other molecules with metal-binding capability can all Participate in a major purpose while in the therapeutic opportunity of iron chelation protocols. There are plenty of examples of this kind of interactions such as the day-to-day use of vitamin C in TM sufferers, which in combination with DF improves iron excretion [210,215,216].

On the other hand, despite the fact that survival in TM has significantly improved Along with the introduction of RBC transfusions, it shortly became evident that the Make-up of excessive iron in many organs plus the involved toxicity was also lifetime-threatening and here could be lethal Except the excess iron was taken out.
