Aluminum hydroxide is an inorganic salt used as an antacid. It is a basic compound that acts by neutralizing hydrochloric acid in gastric secretions. Subsequent increases in pH may inhibit the action of pepsin. An increase in bicarbonate ions and prostaglandins may also confer cytoprotective effects.

Gastric-peptic disease occurs as a result of an imbalance between protective factors, such as mucus, bicarbonate, and prostaglandin secretion, and aggressive factors, such as hydrochloric acid, pepsin, and Helicobacter pylori (H. pylori). Antacids work by restoring acid-base balance, attenuating the pepsin activity and increasing bicarbonate and prostaglandin secretion.

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.

Simethicone is used as an antiflatulent to relieve symptoms commonly referred to gas including upper GI bloating, pressure, fullness or stuffed feeling. The clinical use of Simeticone is based on its antifoaming properties. Its antifoaming action relieves flatulence by dispersing and preventing the formation of mucous surrounded gas pockets in the GI tract. Simeticone acts in the stomach and intestines to change the surface tension of gas bubbles, enabling them to coalesce; thus gas is freed and eliminated more easily by belching or passing flatus. Simeticone aids in the elimination of gas from the GI tract and can be used to reduce postoperative gas pains. Simeticone can also be used prior to gastroscopy to enhance visualization and prior to radiography of the intestine to reduce gas shadows.

Simethicone decreases the surface tension of gas bubbles in the gastrointestinal tract, facilitating their expulsion. It has a short duration of action as it is generally given as needed, and a wide therapeutic index as it is not systemically absorbed.

Uses

Aluminum hydroxide is an antacid used for the symptomatic relief of heartburn, acid indigestion, and sour stomach.

For relief of heartburn and acid indigestion.

Acid regurgitation, Constipation, Gastric ulcer, Gastrointestinal hyperacidity, Heartburn, Indigestion, Non ulcer dyspepsia, Osmotic laxative

Flatulence, abdominal distention, fullness, gas and windy colic: Simethicone is an excellent and effective antiflatulent. It is used for relief of the painful symptoms of excess gas in the digestive tract. Such gas is frequently caused by excessive swallowing of air or by eating foods that disagree. Simethicone drop is especially used in infants, acts in the stomach and intestines. Thus Simethicone enables freeing and eliminating the gas more easily by belching or passing flatus.

Large bowel preparation: Addition of Simethicone to a polyethylene glycol bowel preparation produces symptomatic improvement prior to investigation in the management of accidental ingestion of foaming detergents.

Treatment of poisoning: Simethicone has an anecdotal use as an antifoaming agent in the management of accidental ingestion of foaming detergents.

How Mylanta works

Aluminum hydroxide is a basic inorganic salt that acts by neutralizing hydrochloric acid in gastric secretions. Aluminum hydroxide is slowly solubilized in the stomach and reacts with hydrochloric acid to form aluminum chloride and water. 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.

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.

Simethicone is a surfactant that decreases the surface tension of gas bubbles in the gastrointestinal tract, more easily allowing gas to exit the body.

Side Effects

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

Simethicone is physiologically inert and no adverse effect has been noted after oral ingestion.

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.

Data regarding overdoses with simethicone are rare due to the fact that it is not systemically absorbed.. In the case of an overdose stop the drug and initiate symptomatic and supportive care.

Precaution

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

Do not exceed 12 doses per day except under the advice and supervision of a physician.

Interaction

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

There is no evidence that Simethicone modifies the effect of other drugs. The defoaming effect of Simethicone is reduced by antacids such as Aluminium Hydroxide and Magnesium Carbonate, which absorb the Silicone.

Volume of Distribution

The peak action and distribution of magnesium hydroxide are variable.

Simethicone is not systemically absorbed and so these data are not readily available.

Elimination Route

Approximately 17-30% of the aluminum chloride formed is absorbed.

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

Simethicone is not systemically absorbed and so these data are not readily available.

Half Life

N/A

Simethicone is not systemically absorbed and so these data are not readily available.

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.

Simethicone is not systemically absorbed and so these data are not readily available.

Elimination Route

Absorbed aluminum chloride is rapidly eliminated by the kidneys in patients with normal renal function.

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.

Simethicone is eliminated in the feces.
