Antanil (200 mg+125 mg)/5 ml Oral Suspension

Antanil (200 mg+125 mg)/5 ml Oral Suspension Uses, Dosage, Side Effects, Food Interaction and all others data.

This drug is well-balanced combination of essential non-systemic antacids which excel in efficacy and palatability. These are dependable antacid preparations without acid rebound, constipating or cathertic effects. Both the preparations provide symptomatic relief of hyperacidity associated with heartburn, acid ingestion or sour stomach.

Aluminium hydroxide gel, a slow acting antacid and an adsorbent with prolonged effect, has high neutralizing power. Magnesium Hydroxide possesses a slow but sustained acid neutralizing property. Antacids of both tablet and suspension possess adsorbent property. They form a protecting coating over the ulcer surface facilitating its healing; thus protecting the sensitive mucosa of stomach and duodenum from further irritation.

How Antanil (200 mg+125 mg)/5 ml Oral Suspension works

The suspension of magnesium hydroxide is ingested and enters the stomach. According to the amount ingested, the magnesium hydroxide will either act as an antacid or a laxative.

Through the ingestion of 0.5-1.5 grams (in adults) the magnesium hydroxide will act by simple acid neutralization in the stomach. The hydroxide ions from the magnesium hydroxide suspension will combine with the acidic H+ ions of the hydrochloric acid made by the stomachs parietal cells. This neutralization reaction will result in the formation of magnesium chloride and water.

Through the ingestion of 2-5 grams (in adults) the magnesium hydroxide acts as a laxative in the colon. The majority of the suspension is not absorbed in the intestinal tract and will create an osmotic effect to draw water into the gut from surrounding tissues. With this increase of water in the intestines, the feces will soften and the intraluminal volume of the feces will increase. These effects still stimulate intestinal motility and induce the urge to defecate. Magnesium hydroxide will also release cholecystokinin (CKK) in the intestines which will accumulate water and electrolytes in the lumen and furthermore increase intestinal motility.

Dosage

Antanil (200 mg+125 mg)/5 ml Oral Suspension dosage

Tablet: Two tablets 1-3 hours after meal and at bed time or as directed by the physician.

Suspension: 2 tea spoonful 1-3 hours after meal and at bed time or as directed by the physician.

Side Effects

Long term use of any antacid results in alkaluria, which may predispose to nephrolithiasis by forming precipitation of calcium phosphate.

Toxicity

LD50=8500 mg/kg (rat, oral)

Common side effects include drowsiness or flushing (warmth, redness or tingly feeling).

Daily use of magnesium hydroxide can result in fluid and electrolyte disturbances.

Excessive use of the laxative effects of magnesium hydroxide may result in abdominal cramping, nausea and/or diarrhea.

In overdose, symptoms of gastrointestinal irritation and/or watery diarrhea may occur.

Magnesium hydroxide poisoning can result in hypermagnesemia which includes symptoms of: nausea, vomiting, flushing, thirst, hypotension, drowsiness, confusion, loss of tendon reflexes, muscle weakness, respiratory depression, cardiac arrhythmias, coma and cardiac arrest.

Not to be used in individuals with any form of kidney disease or renal failure, a magnesium restricted diet or with any sudden changes in bowel movement lasting over two weeks. Also not to be used in those individuals with abdominal pain, nausea, vomiting, symptoms of appendicitis or myocardial damage, heart block, fecal impaction, rectal fissures, intestinal obstruction or perforation or renal disease. Not to be used in women who are about to deliver as magnesium crosses the placenta and is excreted in small amounts in breast milk.

Using magnesium hydroxide with aluminum hydroxide can decrease the absorption rate of these drugs.

Magnesium hydroxide can react with digoxin, dicoumerol and cimetidine.

Use of ibuprofen with magnesium hydroxide can increase the absorption of the ibuprofen.

Use of magnesium hydroxide with penicallamine, bisphosphates, ketoconazole, quinolones or tetracycline can decrease the absorption of these drugs.

Enteric-coated tablets can be prematurely released when taken with magnesium hydroxide.

It is important to routinely monitor levels of serum magnesium and potassium in patients using magnesium hydroxide. Serum magnesium levels are necessary to determine how much magnesium is being absorbed and how much is being excreted by the kidneys. Excessive diarrhea can occur from use of magnesium hydroxide and thus it is important to also monitor serum potassium levels to ensure hypokalemia does not occur.

Precaution

Chronic renal impairment; CHF; oedema; cirrhosis and low Na diets; patients with recent Gl haemorrhage. Administer 2-3 hrs before/after another medication to minimise drug interactions. Pregnancy and lactation

Colostomy, ileostomy; electrolyte imbalance. Monitor for toxicity in patients with impaired renal function. Pregnancy.

Interaction

This drug inhibits the absorption of following drugs: Azithromycin, cefpodoxime, ciprofloxacin, isoniazid, rifampicin, norfloxacin, ofloxacin, pivampicillin, tetracyclines, Gabapentin and phenytoin, Itraconazole, ketoconazole, Chloroquine ,hydroxychloroquine and Phenothiazines.

Volume of Distribution

The peak action and distribution of magnesium hydroxide are variable.

Elimination Route

About 15%-50% of magnesium hydroxide is absorbed very slowly through the small intestine.

Half Life

N/A

Clearance

Magnesium hydroxide is mainly excreted in the urine by the kidneys. Since the kidneys play a major role in its clearance, individuals with renal failure are at risk of hypermagnesemia with long term consumption as the appropriate amounts of magnesium may not be excreted.

Elimination Route

After oral administration, up to 50% of the magnesium hydroxide suspension may be absorbed as magnesium ions through the small intestines and then rapidly excreted in the urine through the kidneys. The unabsorbed drug is mainly excreted in the feces and saliva.

Pregnancy & Breastfeeding use

It is advised to avoid antacid preparations in the first trimester of pregnancy.

Contraindication

This is contraindicated in hypophosphataemia. It is also contraindicated in alkalosis and hypermagnesaemia where abdominal distention may be due to partial or complete intestinal obstruction.

Alimentary preparations: This drug reduces the absorption of tetracycline when given concomitantly. These should not be used concomitantly.

Storage Condition

Store in cool and dry place, out of reach of children.
