Uses

This capsule is indicated for the treatment and prophylaxis of iron, folic acid, zinc, vitamin-B complex and vitamin-C deficiency, especially during pregnancy and lactation.

Zilvit Capsule is also used to associated treatment for these conditions: Anaemia folate deficiency, Folate deficiency, Iron Deficiency (ID), Iron Deficiency Anemia (IDA), Latent Iron Deficiency, Neural Tube Defects (NTDs), Vitamin Deficiency, Methotrexate toxicity, Nutritional supplementationDry Eyes, Local itching, Localized pain, Localized swelling, Nutritional supplementation

How Zilvit Capsule works

Folic acid, as it is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase (DHFR). These folic acid congeners are transported across cells by receptor-mediated endocytosis where they are needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylate tRNA, and generate and use formate. Using vitamin B12 as a cofactor, folic acid can normalize high homocysteine levels by remethylation of homocysteine to methionine via methionine synthetase.

Zinc inhibits cAMP-induced, chloride-dependent fluid secretion by inhibiting basolateral potassium (K) channels, in in-vitro studies with rat ileum. This study has also shown the specificity of Zn to cAMP-activated K channels, because zinc did not block the calcium (Ca)-mediated K channels. As this study was not performed in Zn-deficient animals, it provides evidence that Zn is probably effective in the absence of Zn deficiency. Zinc also improves the absorption of water and electrolytes, improves regeneration of the intestinal epithelium, increases the levels of brush border enzymes, and enhances the immune response, allowing for a better clearance of the pathogens.

Dosage

Zilvit Capsule dosage

Adult: One capsule daily before food or as directed by the physician.Use in Children & Adolescents: Upon consultation with a doctor, recommended to use in children & adolescents.

May be taken with or without food.

Side Effects

Allergic sensitization has been reported following oral administration of Folic acid. Oral iron preparation may cause constipation, particularly in older patients.

Precaution

Care should be taken in patients who may develop iron overload, such as those with hemochromatosis, hemolytic anemia or red cell aplasia. Iron chelates with tetracycline and absorption may be impaired.

Interaction

Carbonyl Iron decreases the absorption of tetracycline antibiotics, quinolone antibiotics, levodopa, levothyroxine, methyldopa and penicillamine. Folic Acid interacts with antiepileptics, so plasma concentrations of phenobarbital, phenytoin and primidone are possibly reduced.

Volume of Distribution

Tetrahydrofolic acid derivatives are distributed to all body tissues but are stored primarily in the liver.

After absorption zinc is bound to protein metallothionein in the intestines. Zinc is widely distributed throughout the body. It is primarily stored in RBCs, WBCs, muscles, bones, Skin, Kidneys, Liver, Pancreas, retina, and prostate.

Elimination Route

Folic acid is absorbed rapidly from the small intestine, primarily from the proximal portion. Naturally occurring conjugated folates are reduced enzymatically to folic acid in the gastrointestinal tract prior to absorption. Folic acid appears in the plasma approximately 15 to 30 minutes after an oral dose; peak levels are generally reached within 1 hour.

Approximately 20 to 30% of dietary zinc is absorbed, primarily from the duodenum and ileum. The amount absorbed is dependent on the bioavailability from food. Zinc is the most bioavailable from red meat and oysters. Phytates may impair absorption by chelation and formation of insoluble complexes at an alkaline pH. After absorption, zinc is bound in the intestine to the protein metallothionein. Endogenous zinc can be reabsorbed in the ileum and colon, creating an enteropancreatic circulation of zinc.

Half Life

3 hours

Elimination Route

After a single oral dose of 100 mcg of folic acid in a limited number of normal adults, only a trace amount of the drug appeared in the urine. An oral dose of 5 mg in 1 study and a dose of 40 mcg/kg of body weight in another study resulted in approximately 50% of the dose appearing in the urine. After a single oral dose of 15 mg, up to 90% of the dose was recovered in the urine. A majority of the metabolic products appeared in the urine after 6 hours; excretion was generally complete within 24 hours. Small amounts of orally administered folic acid have also been recovered in the feces. Folic acid is also excreted in the milk of lactating mothers.

Primarily fecal (approximately 90%); to a lesser extent in the urine and in perspiration.

Pregnancy & Breastfeeding use

Use of any drug during first trimester of pregnancy should be avoided if possible. Thus administration of Iron during the first trimester requires definite evidence of Iron deficiency. Prophylaxis of Iron deficiency where inadequate diet calls for supplementary Zinc and Folic acid is justified during the remainder of the pregnancy.

Contraindication

It is contraindicated in patients with a known hypersensitivity to any of the ingredients. Iron therapy is contraindicated in the presence of haemolytic anaemia.
