Vit B12

About Vit B12
N/A
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 B12
Absorption: 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.

Lactobacillus

About Lactobacillus
Lactic acid bacteria, Probiotic,Antidiarrhoeal.
Mechanism of Action of Lactobacillus
Lactobacillus is a probiotic and it is called as friendly bacteria. It is used along with antibiotic in order to restore the body`s natural microbial flora with in the digestive tract. Lactobacillus helps in the breakdown of food and leads to the production of lactic acid, hydrogen peroxide and other byproducts. This will alter the intestinal pH and that make the environment hostile for pathogens.

Absorption: It is orally well absorbed after oral administration.

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.
Onset of Action for Folic Acid
Oral: 20 to 30minutes
I.V.: 5 minutes
I.M.:10 to 20minutes
