代谢

三价铁离子通过十二指肠细胞色素B还原酶转化为二价铁。重链铁蛋白也可能将三价铁转化为二价铁。

Ferric cation is converted to ferrous iron by duodenal cytochrome B reductase. The heavy chain ferritin may also convert ferric iron to ferrous iron

毒理性

• 毒性总结

铁过量的患者可能会出现恶心、呕吐、腹痛、腹泻、液体和血液流失、低血容量、呕血、穿孔和腹膜炎。轻微过量可以通过对症和支持性措施进行治疗。更严重的过量可能需要更强烈的治疗，包括螯合剂和静脉输液。在铁过量的情况下，活性炭不太可能有益。大鼠的急性口服LD50为1487毫克/千克，小鼠为1520毫克/千克。家兔的急性皮肤LD50为2000毫克/千克。

Patients experiencing an overdose of iron may present with nausea, vomiting, abdominal pain, diarrhea, fluid and blood loss, hypovolemia, hematemesis, perforation, and peritonitis. Mild overdoses can be treated with symptomatic and supportive measures. More severe overdoses may require more intense treatment including chelating agents, and intravenous fluids. Activated charcoal is not expected to be beneficial in the case of iron overdose. The acute oral LD50 in rats is 1487mg/kg and in mice is 1520mg/kg. The acute dermal LD50 in rabbits is 2000mg/kg.

毒理性

• 蛋白质结合

铁三价铁被还原成二价铁，二价铁通过血清中的转铁蛋白进行运输。

Ferric iron is reduced to ferrous iron, which is carried by transferrin in serum.

吸收、分配和排泄

• 吸收

三价铁的生物利用率低于二价铁制剂。四价铁三柠酸十水合物具有二价抗坏血酸19%的生物利用率。

Ferric iron has been shown to have inferior bioavailability to ferrous iron preparations. Tetraferric tricitrate decahydrate has 19% the bioavailability of ferrous ascorbate.

吸收、分配和排泄

• 消除途径

未被吸收的口服四铁三枸橼酸十水合物通过粪便排出体外。从四铁三枸橼酸十水合物吸收的铁通常不会通过除失血和上皮细胞脱落的途径从体内排出。

Unabsorbed oral Tetraferric tricitrate decahydrate is eliminated in the feces. The absorbed iron from Tetraferric tricitrate decahydrate is generally not eliminated from the body by any route other than blood loss and exfoliation of epithelial cells.

吸收、分配和排泄

• 清除

关于铁的清除数据并不容易获得。然而，由于上皮细胞的脱落，铁的损失大约是每天1毫克。

Data regarding the clearance of iron is not readily available. However, iron loss due to exfoliation of epithelial cells is approximately 1mg/day.
