Composition and Active Ingredients
Chemical Composition of Desferal
Desferal includes a substance called deferoxamine mesylate, which acts as a water agent in the body to bind excess iron and create stable compounds that can be expelled through urine or feces.
Mechanism of Action Based on Its Active Ingredients
Deferoxamine functions by attaching to ions in the body to neutralize free iron and protect tissues and organs from oxidative harm.
Role of Active Ingredients in Therapeutic Effects
- Helps shield organs such as the liver and heart from the effects of excessive iron levels.
- Effectively lowers the levels of serum ferritin in the bloodstream.
- Reduces the risks associated with iron accumulation over time.
Uses of Desferal Injection
Treatment of Chronic Iron Overload
Use in Managing Thalassemia Major
Application in Hemochromatosis
For individuals with hereditary hemochromatosis, Desferal serves as an adjunct therapy when phlebotomy is insufficient or contraindicated. It aids in managing systemic iron accumulation.
Off-Label Uses in Aluminum Toxicity
Desferal is sometimes used in a way to address aluminum toxicity in individuals with kidney disease who are receiving dialysis treatments.
How Desferal Injection Works
Mechanism of Iron Chelation
Desferal works by combining with iron ions to make them inactive and prepared for removal from the body system, which in turn helps avoid the buildup of iron in tissues.
Role in Preventing Organ Damage
By binding to iron ions in the body's tissues and cells, Desferal helps decrease damage and lipid oxidation, protecting vital organs such as the heart, liver, and pancreas from potential harm that could be permanent.
Biological Processes Targeted by the Drug
The medication is designed to focus on non-transferrin-bound iron (NTBI )and labile plasma iron ( LPI) as they are primarily responsible for the harmful effects of iron overload.
Dosage and Administration Guidelines
Standard Dosage for Adults and Children
The correct amount of medicine depends both on the amount of iron in the body and on how much you weigh. An adult usually takes between 20 and 40 mg per kilogram each day, while children take adjusted doses based on their size.
Routes of Administration
- Subcutaneous: Commonly preferred for continuous infusion.
- Intramuscular: Used for specific cases requiring quick intervention.
- Intravenous: Reserved for acute iron toxicity or emergencies.
Factors Influencing Dosage Adjustments
Adjusting the dosage is greatly influenced by factors such as kidney function status and serum ferritin levels, as well as how the patient can tolerate it.
Step-by-Step Guide for Safe Administration
- Prepare the medication by mixing it with water meant for injection purposes.
- Make sure the answer is easy to understand and doesn't contain any particles.
