Pharmacological Action
Iron is the main component of hemoglobin and myoglobin. After the ferrous ions in ferrous fumarate are oxidized to ferric ions by ceruloplasmin in the blood, they combine with transferrin in the plasma and are transported to various tissues in the body to participate in the formation of hemoglobin. At the same time, most of the enzymes related to the tricarboxylic acid cycle contain iron or can only function in the presence of iron. Supplementing iron agents can correct the relevant symptoms of iron - deficient patients.
