How Zencal K2 works

Calcium carbonate is a basic inorganic salt that acts by neutralizing hydrochloric acid in gastric secretions. It also inhibits the action of pepsin by increasing the pH and via adsorption. Cytoprotective effects may occur through increases in bicarbonate ion (HCO₃^-) and prostaglandins. Neutralization of hydrochloric acid results in the formation of calcium chloride, carbon dioxide and water. Approximately 90% of calcium chloride is converted to insoluble calcium salts (e.g. calcium carbonate and calcium phosphate).

The term "Milk of Magnesia" was first used to describe a white aqueous, mildly alkaline suspension of magnesium hydroxide formulated at about 8%w/v. Milk of magnesia is primarily used to alleviate constipation, but can also be used to relieve indigestion and heartburn. When taken internally by mouth as a laxative, the osmotic force of the magnesia suspension acts to draw fluids from the body and to retain those already within the lumen of the intestine, serving to distend the bowel, thus stimulating nerves within the colon wall, inducing peristalsis and resulting in evacuation of colonic contents. Magnesium supplements have also been shown to reduce platelet aggregation by inhibiting in the influx of calcium, a crucial component of platelet aggregation.

Dosage

Zencal K2 dosage

Calcium Carbonate is always used orally and when used as an antacid the recommended doses for adults are equivalent to 540-2000 mg Calcium Carbonate per day, doses for children being half of those for adults. As a dietary supplement, such as for the prevention of osteoporosis, 1250-3750 mg Calcium Carbonate (500-1500 mg calcium) daily is recommended in general, but again this will need to be tailored to the individual patient depending on any specific disease such as Calcium deficiency, malabsorption or parathyroid function. In pregnancy and lactation therecommended daily dose of calcium is 1200-1500 mg. In chronic renal failure the doses used vary from 2.5 - 9.0 gm Calcium Carbonate per day and need to be adjusted according to the individual patient. To maximize effective phosphate binding in this context the Calcium Carbonate should be given with meals.

Tablet: The usual adult dosage is one 500 mcg tablet three times daily. The dosage should be adjusted according to the age of patient and the severity of symptoms.

Injection:

• Peripheral neuropathies: The usual adult dosage is one ampoule equivalent to 500 mcg of Mecobalamin, administered intramuscularly or intravenously three times a week.The dosage should be adjusted according to the age of patient and the severity of symptoms.
• Megaloblastic anemia: The usual adult dosage is one ampoule equivalent to 500 mcg of Mecobalamin, administered intramuscularly or intravenously three times a week. After about two months of administration, dosage should be changed to one ampoule equivalent to 500 mcg of Mecobalamin every one to three months as maintenance therapy

Syrup-

• Children under 10 kg: One teaspoonful 2 times daily.
• Children within 10 to 30 kg: Two teaspoonful 1-3 times daily.
• Adults and children over 30 kg body weight: Four teaspoonful 1-3 times daily.

Tablet-In the treatment of Diarrhoea Zinc should be given as soon as diarrhoea starts:

• For infants between 2 to 6 months of age: 10 mg Zinc once daily for 10-14 days.
• For children between 6 months to 5 years of age: 20 mg Zinc once daily for 10-14 days.

For other indications:

• The recommended dose for children: 2 to 2.5 mg/kg/day.
• Children under 10 kg: 10 mg Zinc 2 times daily.
• Children within 10 to 30 kg: 20 mg Zinc 1-3 times daily.
• Adults and children over 30 kg body weight: 40 mg Zinc 1-3 times daily.

Dispersible Tablet-

• Place the tablet in a teaspoon
• Add adequate amount of water
• Let the tablet dissolve completely
• Give the entire spoonful solution

Side Effects

In rare cases, flatulence, diarrhoea or constipation.

Generally Mecobalamin is well tolerated. However, a few side effects like GI discomfort (including anorexia, nausea or diarrhea) & rash may be seen after administration of Mecobalamin.

In case of zinc mild side effects such as gastric ulcer, nausea, vomiting, metallic taste, headache, drowsiness have been observed.

Precaution

In the presence of mild hypercalciuria, excretion levels must be carefully monitored and where necessary the dose of calcium carbonate should be reduced or treatment should be stopped. Patients with a history of stone formation should also be recommended to increase their fluid intake. High dosage of vitamin D should be avoided during Calcium therapy unless specifically indicated.

The medicine should not be used for months if there is no response at all after its use for a certain period of time.

Concurrent administration of Zinc salt with penicillamine might diminish the effect of Penicillamine. The absorption of Zinc, although poor, may be decreased by various compounds including some foods. Chelation may occur with tetracyclines.

Interaction

Oral calcium can reduce internal absorption of tetracycline and fluoride prepa-rations and an interval of at least 3 hours should therefore be allowed between ingestion of these medications. Vitamin D increases internal absorption of calcium. The intestinal uptake of calcium may be reduced by concomitant ingestion of certain foods (e.g. spinach, milk and milk products).

Decreased GI tract absorption with neomycin, aminosalicylic acid, H2-blockers and colchicine. Reduced serum concentrations with oral contraceptives. Reduced effects in anaemia with parenteral chloramphenicol.

Zinc may inhibit the absorption of concurrently administered tetracyclines, when both are being given an interval of at least 3 hours.

Volume of Distribution

Calcium is rapidly distributed taken up by skeletal tissues following absorption and distribution into extracellular fluids. Bone contains 99% of the body's calcium and the remaining 1% is approximately equally distributed between intracellular and extracellular fluids.

Elimination Route

Maximal absorption occurs at doses of 500 mg or less taken with food. Oral bioavailability depends on intestinal pH, the presence of food and dosage.

Elimination Route

Excreted mainly in the feces. The majority of renally filtered calcium is reabsorbed in the ascending limb of the loop of Henle and the proximal and distal convoluted tubules. Also secreted by sweat glands.

Pregnancy & Breastfeeding use

Pregnant women : Calcium containing drugs are used widely in pregnancy by way of calcium supplement or antacid therapy. No relationship between malformation in general and calcium exposure has been noted.

Lactating mother : There is no contraindication to the use of calcium carbonate in lactating mother.

Not recommended during pregnancy & lactation.

Pregnant women and nursing mothers should avoid zinc doses higher than RDA amounts.

Contraindication

Hypersensitivity to the Calcium Carbonate or any inactive ingredient of the medication. Hypercalcemia (e.g. in hyperparathyroidism, overdosage of vitamin D, demineralizing tumours such as plasmacytomas and bone metastases), severe hypercalcuria, several renal insufficiency.

Hypersensitivity to any component of this product.

It is contraindicated in patients with hypersensitivity to Zinc.

Special Warning

USE IN CHILDREN: Calcium carbonate has been extensively studied in children and infants with chronic renal failure and is both safe and effective.

USE IN ELDERLY: In case of elderly patients with renal failure when calcium carbonate is taken constipation may be troublesome one for this group. For this reason, monitoring of serum calcium and phosphate is of course indicated for elderly patients.

Use in children: Not recommended.

Acute Overdose

Zinc sulphate is corrosive in overdose. Symptoms are corrosion and inflammation of the mucous membrane of the mouth and stomach; ulceration of the stomach followed by perforation may occur. Gastric lavage and emesis should be avoided. Demulcents such as milk should be given. Chelating agents such as sodium edetate may be useful.

Storage Condition

Store in a cool, dry place in controlled room temperature.

Oral: Store at room temperature. Protect from moisture and light.

Parenteral: Store at room temperature. Do not expose to direct light.

Store in a cool place. The syrup should be protected from light.
