Description

HEMATINIC SYRUP

Sodium feredetate 231 mg + Cyanocobalamin (Vit.B12) 15
mcg + Folic acid 1.5 mg Syrup

 Sodium Feredetate

The iron preparation Sodium feredate (sodium iron edetate) is not an iron salt. It is an unionised form. It is not astringent and does not discolour teeth. Sodium feredetate breaks down within the gastrointestinal tract and release elemental iron, which is then absorbed.
Iron formulations exert haematinic action by being an essential constituent of haemoglobin. It is necessary for the oxidative process of living tissues.
Pharmacokinets of Sodium Feredetate Absorption:

Absorbed orally in ferrous form and poorly absorbed in healthy individuals (about 10%) but in patients suffering from iron deficiency anaemia up to 60% dose is absorbed. Distribution: Transported in a transferrin bound form in to bone marrow for incorporation in to haemoglobin. Metabolism: Iron liberated by destruction of haemoglobin is reused by the body. Excretion: Excretion of iron is minimal. Loss usually occurs in nails, faeces, urine, hair, sweat, and bile.

Side Effects Sodium Feredetate:

1.Nausea
2.Epigasttric distress
3.Vomiting
4.Constipation
5.Diarrhoea
6.Black stools

 Special Precautions while taking Sodium Feredetate:

1. Prolonged use
2. Minimise gastrointestinal discomfort by taking along with meals and gradually increasing the recommended dosage
3. Discontinue if intolerance occurs
4. Higher doses are required for geriatric patients

Vit B12

Mechanism of Action of Vit B12:

Vitamin B12 is an essential constituent for growth, cell reproduction, hematopoiesis, and nucleoprotein and myelin synthesis. Vitamin B12 is converted in to coenzyme B12 in the tissues which is essential for conversion of methyl-malonate to succinate and synthesis of methionine from homocystine. It is also associated with fat and carbohydrate metabolism and protein synthesis. Cells characterized by rapid division such as epithelial cells, bone marrow, and myeloid cells appear to have greatest requirement of Cyanocobalamin.

Pharmacokinets of Vit B12Absorption:

Absorbed irregularly after oral administration and absorption depends on Ca and intrinsic factor. It is also administered subcutaneously and intramuscularly.
Distribution: Distributed in to liver, bone marrow, and other tissues. It crosses the placenta and appears in breast milk.
Metabolism: It is metabolized in liver.
Excretion: In normal dosage it is reabsorbed from bile and a minute portion is excreted through urine but the extra drug is excreted through urine.

Folic Acid

About Folic Acid Dietary supplement, Folate derivative( B9 ), Water Soluble Vitamin.

Mechanism of Action of Folic Acid

Folic acid reduced by enzymes folate reductase and dihydrofolate reductase and forms dihydrofolic acid tetrahydrofolic acid respectively. Tetrahydrofolic acid acts as a coenzyme which mediates a number of one carbon transfer reactions by carrying a methyl group as an adduct.

It involves a number of reactions such as 1).conversion of homocysteine to methionine. 2).synthesis of thymidylate which is an essential constituent of DNA from methylene-tetrahydrofolic acid. 3). Conversion of serine to glycine by tetrahydrofolic acid and forms methylene-tetrahydrofolic acid. 4).to introduce carbon units at position 2 and 8 during de novo purine synthesis requires formyl-tetrahydrofolic acid and methenyl-tetrahydrofolic acid.5).generation and utilization of “formate pool”. 6).For mediating formino group transfer in histidine metabolism. Folic acid is required to maintain normal erythropoiesis and nucleoprotein synthesis.

Pharmacokinets of Folic Acid

Absorption: Well absorbed orally
Distribution: Widely distributed in the body and highest concentration is seen in liver. It appears in the CSF and breast milk
Metabolism: Metabolized in to N-methyl tetrahydrofolic acid in liver
Excretion: Extra drug is excreted unchanged in urine. A small portion of folate is lost by a combination of urinary and fecal excretion and oxidative cleavage of molecule.

Indications for Folic Acid1. Megaloblastic anaemia
2. Folic acid deficiency
3. Anaemias of pregnancy
4. Nutritional anaemia
5. Alcoholism
6. Tropical sprue
7. Non tropical sprue
