For Healthcare Professionals: Pharmacodynamic Properties of I Fortis™ Chewable Tablets

Pharmacotherapeutic Group:

  • Iron preparations in combination with folic acid
  • ATC Code: B03AD04

Mechanism of Action:

I Fortis™ is a combination preparation containing iron (III)-hydroxide polymaltose complex (IPC) and folic acid for the treatment and prevention of iron deficiency, particularly before, during, and after pregnancy (including lactation).

Key Roles of Active Ingredients:

  1. Iron (III)-Hydroxide Polymaltose Complex (IPC):

    • A macromolecular complex where individual iron particles are embedded within a carbohydrate polymer (polymaltose).
    • This structure ensures controlled release of iron without causing damage to the gastrointestinal (GI) tract, minimizing common side effects like gastric irritation and constipation.
    • Unlike conventional ferrous iron salts, IPC contains iron in the ferric (Fe3+) form, which eliminates the electron transfer step needed in ferrous salts, preventing the formation of free radicals.
  2. Folic Acid:

    • Essential for DNA synthesis and cellular division, especially during pregnancy.
    • Deficiency during the first weeks of gestation may lead to neural tube defects and other congenital malformations.
    • Plays a crucial role in erythropoiesis, working synergistically with iron to treat anemia.

Advantages Over Conventional Iron Salts:

  • Reduced GI Disturbance: The IPC complex minimizes gastric irritation compared to ferrous salts.
  • Free Radical Prevention: Since iron is in the ferric form, the absence of free electron release prevents harmful free radical formation.
  • High Bioavailability: Ensures effective absorption of iron without causing oxidative stress.
  • Better Tolerance: Suitable for long-term administration, even during sensitive periods like pregnancy and lactation.

Indications:

  • Treatment and prevention of iron deficiency anemia (IDA) before, during, and after pregnancy
  • Supplementation during lactation
  • Support for normal erythropoiesis

Clinical Applications:

  • Management of iron-deficient states with minimal side effects
  • Prevention of congenital anomalies due to folic acid deficiency
  • Well-tolerated alternative for patients intolerant to traditional ferrous formulations

 

 

I Fortis™: Undesirable Effects & Overdose Management


Undesirable Effects

I Fortis™ Chewable Tablets are generally well-tolerated. However, in rare cases, the following adverse effects may be observed:

Gastrointestinal Disturbances

  • Nausea
  • Diarrhea
  • Constipation

These symptoms are usually mild and self-limiting. Patients are advised to take I Fortis™ after meals to minimize gastrointestinal irritation.


Overdose Symptoms

An acute overdose of iron-containing products can be toxic and may lead to:

Early Symptoms (Within 1–6 Hours Post-Ingestion)

  • Severe nausea and vomiting
  • Abdominal pain
  • Vomiting of blood (hematemesis)
  • Diarrhea, which may be bloody
  • Lethargy and pallor
  • Hypotension and circulatory collapse

Severe and Delayed Symptoms (12–48 Hours Post-Ingestion)

  • Apparent symptom relief may occur, but damage may continue internally
  • Encephalopathy: Confusion, drowsiness, or seizures
  • Acute hepatic necrosis: Jaundice and liver failure
  • Acute renal failure: Reduced urine output

Management of Overdose

1. Gastric Decontamination

  • Perform gastric lavage as soon as possible to remove unabsorbed iron from the stomach.
  • Introduce 5 grams of deferoxamine (Desferal®) directly into the stomach following lavage to bind free iron.

2. Monitor Iron Levels

  • Measure serum iron levels to assess toxicity severity.
    • Normal serum iron: 50–150 µg/dL
    • Toxicity likely when serum iron exceeds 300 µg/dL

3. Deferoxamine Therapy

  • For severe cases, initiate intravenous deferoxamine infusion:
    • Dose: 15 mg/kg/hour intravenously (up to a maximum of 6 grams per day)
    • Continue until serum iron falls below toxic levels and symptoms improve.

4. Supportive Treatment

  • Maintain fluid balance and provide cardiovascular support as needed.
  • Monitor and treat any metabolic acidosis.
  • Manage hepatic and renal complications based on clinical presentation.

Important Notes:

    • Long-term monitoring: Patients recovering from severe iron overdose may need follow-up for liver and kidney function.
    • Pediatric cases: Special caution is advised since accidental ingestion in children can be fatal.
