Objectives:
The aim of this study was to compare the efficacy and safety of intravenous iron with oral iron in the treatment of iron deficiency anemia of pregnancy.
Methods:
A randomized experimental study was conducted at K. J. Somaiya Hospital involving 200 pregnant women with iron deficiency anemia. In the intravenous group iron dose was calculated from: Total iron dose required (mg) = 2.4 × weight kg × target hemoglobin - actual hemoglobin) g/dl + 500. Target hemoglobin was set at 12 g/dl. In the oral group patients received 200 mg oral ferrous ascorbate daily. Hemoglobin and serum ferritin were reviewed at 2, 4, and 6 weeks. Paired and independent t test was applied.
Results:
The change in hemoglobin and ferritin levels from baseline was significantly higher in the intravenous group than the oral group at each measurement (P = 0.000).
Conclusion:
Intravenous iron elevates hemoglobin and restores iron stores faster than oral iron, with no severe adverse reactions.

Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Additional Routes of Drug Administration
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...
