Laxgem Mp Uses, Dosage, Side Effects, Food Interaction and all others data.

Magnesium hydroxide increases peristaltic activity causing osmotic retention of fluids, thus resulting in bowel evacuation. It also reduces stomach acid by reacting with hydrochloric acid to form Mg chloride.

As an antacid, magnesium hydroxide suspension neutralizes gastric acid by reacting with hydrochloric acid in the stomach to form magnesium chloride and water. It is practically insoluble in water and does not have any effect until it reacts with the hydrochloric acid in the stomach. There, it decreases the direct acid irritant effect and increases the pH in the stomach leading to inactivation of pepsin. Magnesium hydroxide enhances the integrity of the mucosal barrier of the stomach as well as improving the tone of both the gastric and esophageal sphincters.

As a laxative, the magnesium hydroxide works by increasing the osmotic effect in the intestinal tract and drawing water in. This creates distension of the colon which results in an increase in peristaltic movement and bowel evacuation.

Sodium Picosulfate is a triarylmethane group derivative stimulant laxative. After oral administration it is activated by the colonic bacteria and acts locally in the colon. The active form then stimulates the nerve endings of the intestinal wall and results in colonic peristalsis with promotion of accumulation of water and electrolytes in the colonic lumen. This results in stimulation of defecation, reduction of transit time and softening of the stool. Stimulation of the rectum causes increased motility and a feeling of rectal fullness. The rectal effect may help to restore the "call to stool".

How Laxgem Mp 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

Laxgem Mp dosage

Gastrointestinal hyperacidity:

Adult: Up to 1 g daily, usually given in conjunction with an aluminium-containing antacid eg, aluminium hydroxide.

Osmotic laxative:

Adult: 2.4-4.8 g daily as a single dose or in divided doses.
Child: 6-11 yr: 1.2-2.4 g daily; 2-5 yr: 0.4-1.2 g daily. Doses may be given as a single dose or in divided doses.

For oral administration. The following dosages are recommended to be taken at night to produce evacuation the following morning. It is recommended to start with the lowest dose. The dose may be adjusted up to the maximum recommended dose to produce regular stools. The maximum recommended daily dose should not be exceeded:

Adults and children over 10 years of age-

Tablet: 5-10 mg per day.
Oral Solution: 5-10 ml or one to two teaspoonful per day.

Children are aged 4-10 years-

Tablet: 2.5-5 mg per day.
Oral Solution: 2.5-5 ml or Half to one teaspoonful per day.

Children under 4 years of age-

Oral Solution: 0.25 ml/kg body weight per day.

Side Effects

GI irritation, diarrhoea, abdominal cramps; hypermagnesaemia (in patients with renal impairment). Paralytic ileus.

Hypersensitivity, dizziness, syncope, vasovagal response, gastrointestinal disorders, diarrhea, abdominal pain and abdominal cramps, nausea, vomiting.

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

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

Prolonged excessive use may lead to fluid and electrolyte imbalance and hypokalemia. Harmful for those suffering from alcoholism. To be taken into account in pregnant or breast-feeding women, children and high-risk groups such as patients with liver disease or epilepsy.

Interaction

Decreases absorption of tetracyclines and biphosphonates. Separate administration of these and other drugs by around 2 hr.

The concomitant use of diuretics or adreno-corticosteroids may increase the risk of electrolyte imbalance if excessive doses are taken. Concurrent administration of antibiotics may reduce the laxative action of this product.

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

Pregnancy category- A.

There are no reports of undesirable or damaging effects during pregnancy or to the foetus attributable to the use of this product. Use of the drug should be avoided during the first trimester. Clinical data show that neither the active moiety of sodium Picosulfate (BHPM or bis-(p hydroxyphenyl)-pyridyl-2-methane) nor its glucuronides are excreted into the milk of healthy lactating females.

Contraindication

Intestinal obstruction, faecal impaction; renal failure; appendicitis.

Ileus or intestinal obstruction, severe painful and/or feverish acute abdominal conditions (e.g. appendicitis) potentially associated with nausea and vomiting, acute inflammatory bowel diseases, severe dehydration, known hypersensitivity to Sodium Picosulfate or any other component of the product.

Acute Overdose

Laxatives when taken in chronic overdosage may cause chronic diarrhea, abdominal pain, hypokalemia, secondary hyperaldosteronism, and renal calculi. Renal tubular damage, metabolic alkalosis, and muscle weakness secondary to hypokalemia have also been described in association with chronic laxative abuse.
