About Iron (Carbonyl Iron)A highly pure, nontoxic Iron(a minimum 98% iron content), Iron dietary supplement and to treat iron deficiency.Mechanism of Action of Iron (Carbonyl Iron)Iron formulations exerts haematinic action by being an essential constituent of haemoglobin. It is necessary for the oxidative process of living tissues.
Pharmacokinets of Iron (Carbonyl Iron)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.

Interactions for Iron (Carbonyl Iron)(Oral Iron): Antacids: GI absorption of iron reduced.
Ascorbic acid: GI absorption of iron enhanced.
Chloramphenicol: Serum iron levels may be increased.
Cimetidine: GI absorption may be reduced.
Levodopa: Decreased levodopa serum levels.
Methyldopa: May result in decreased efficacy of methyldopa.
Quinolones: GI absorption of quinolones decreased.

Schedule of Iron (Carbonyl Iron)HStorage Requirements for Iron (Carbonyl Iron)Store in a well closed container in a cool dry place. Protect from light.Effects of Missed Dosage of Iron (Carbonyl Iron)Take the missed dose as soon as noticed and if it is the time for next dose then skip the missed dose. Continue the regular schedule. Do not double the dose.Effects of Overdose of Iron (Carbonyl Iron)Treatment includes immediate support of airway, respiration, and circulation. In conscious patients induce emesis with ipecac; if not empty stomach by gastric lavage. Follow emesis with lavage, using a 1% sodium bicarbonate solution to convert iron to less irritating poorly absorbed form. Take abdominal X-ray to determine presence of excess iron.

About Vit B12N/AMechanism of Action of Vit B12Vitamin 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.

About Folic AcidDietary supplement, Folate derivative( B9 ), Water Soluble Vitamin.Mechanism of Action of Folic AcidFolic 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 AcidAbsorption: 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.
