Ferobid Z

Uses

Ferrous Sulfate is used for the treatment and prevention of iron deficiency anaemia and anaemia of pregnancy where routine administration of iron is necessary.

Zinc sulfate is a drug used to replenish low levels of zinc or prevent zinc deficiency, or to test for zinc deficiency.

This medication is a mineral used to treat or prevent low levels of zinc alone and together with oral rehydration therapy (ORT). It is also used as a topical astringent. Zinc Sulfate Injection, USP is indicated for use as a supplement to intravenous solutions given for TPN.

Ferobid Z is also used to associated treatment for these conditions: Dry Eyes, Local itching, Localized pain, Localized swelling, Nutritional supplementation

How Ferobid Z works

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

Ferobid Z dosage

Adult-

• Initial therapeutic dose: 3-4½ teaspoonful daily in divided doses or as prescribed by the physician.
• Maintenance dose: 1½ teaspoonful daily, but if needed up to 1.8g (9 teaspoonful) daily can be given.

Children-

• Under 1 year: ¼ th teaspoonful thrice daily or as directed by physician
• 1-5 years: 1 teaspoonful thrice daily
• 6-12 years: 1½ teaspoonful twice daily.

Should be taken on an empty stomach. Best taken on an empty stomach. May be taken with meals to reduce GI discomfort. Mix with water or fruit juice to avoid temporary staining of teeth. Do not mix with milk.

Side Effects

GI irritation, abdominal pain and cramps, nausea, vomiting, constipation, diarrhoea, dark stool and discoloration of urine; heartburn.

Toxicity

Human : TDLo ( Oral) 45mg/kg/7D-C : Normocytic anemia, pulse rate increase without fall inBP Human: TDLo (oral) 106mg/kg : Hypermotylity, diarrhea Mouse ; LD50 Oral : 245mg/kg Mouse : LD50 : subcutaneous : 781mg/kg

Precaution

Should be administered with caution when given to patients with iron storage or iron absorption disease, haemoglobinopathies or existing gastrointestinal disease.

Interaction

Absorption of iron salt and Tetracycline is diminished when taken concomitantly by mouth. If treatment with both drugs is required iron salt should be given 3 hours before or 2 hours after Tetracycline. Absorption of iron is also decreased in the presence of antacids or when taken with tea.

Volume of Distribution

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

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

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

Pregnancy & Breastfeeding use

Pregnancy Category- Not Classified. FDA has not yet classified the drug into a specified pregnancy category.

Contraindication

Iron therapy is contraindicated in haemachromatosis and haemosiderosis.It should not be given to patients receiving repeated blood transfusion or with anaemia not produced by iron deficiency.

Acute Overdose

Symptoms: Nausea, vomiting, abdominal pain, diarrhoea of green or tarry stools, haematemesis, seizures, drowsiness, metabolic acidosis, hepatic dysfunction, renal failure, coma.

Treatment: Empty stomach contents by gastric lavage. In severe toxicity, IV desferrioxamine may be given. Treatment is supportive. Haemodialysis is unlikely to be useful.
