Antacid: Aluminum Hydroxide Flashcards

Questions and Answers

Explain why some antacids such as Maalox contain magnesium?

Maalox is a magnesium hydroxide drug that is used in combination with aluminum hydroxide to reduce side effects of magnesium causing diarrhea and aluminum causing constipation.

Explain the ideal dosing intervals for antacids?

The ideal dosing interval for antacids is 1 and 3 hours after meals and at bedtime. Chewable tablets should be followed by water, and liquid antacids should be taken with 2 to 4 ounces of water.

Examine the reason antacids containing magnesium are contraindicated for patients with impaired renal function?

They are contraindicated in patients with impaired renal function because of the risk for hypermagnesemia.

Study Notes

Antacid: Aluminum Hydroxide (Amphojel) Study Notes

Maalox combines magnesium hydroxide and aluminum hydroxide to balance side effects; magnesium can cause diarrhea while aluminum might lead to constipation.
The ideal dosing interval for antacids is 1 to 3 hours after meals and at bedtime. Chewable tablets require water afterward, while liquid antacids should be taken with 2 to 4 ounces of water, ensuring no more than 4 ounces is consumed.
Antacids containing magnesium are contraindicated for patients with impaired renal function due to the risk of hypermagnesemia.
Aluminum hydroxide (Amphojel) is a nonsystemic antacid made of alkaline salts like aluminum and magnesium. Long-term use can lead to diarrhea from magnesium or constipation from aluminum and calcium.
Prolonged use of aluminum hydroxide can result in hypophosphatemia, osteoporosis, nephrolithiasis, and osteomalacia.
Aluminum hydroxide is classified as an antiulcer drug and an antacid, commonly known by its trade name, Amphojel.
Contraindications for aluminum hydroxide include hypersensitivity to aluminum and hypophosphatemia from prolonged usage. Caution is advised for older adults.
Aluminum hydroxide decreases the effectiveness of several drugs, including tetracycline, phenothiazines, isoniazid, phenytoin, digoxin, digitalis, quinidine, and amphetamines.
This antacid enhances the effects of benzodiazepines and raises urine pH.
Therapeutically, aluminum hydroxide is used to treat hyperacidity, peptic ulcers, reflux esophagitis, and to reduce hyperphosphatemia by neutralizing gastric acidity.
Common side effects of aluminum hydroxide include anorexia, constipation, and speckled or white stools.
Adverse reactions from aluminum hydroxide may include hypophosphatemia, osteoporosis, nephrolithiasis, and potential gastrointestinal obstruction with long-term use.
Pain relief from antacids typically occurs within 1 to 2 weeks following treatment.
Nursing care measures include advising patients to drink 2 ounces of water post-antacid, taking medication 1 to 3 hours after meals (not at mealtime), and avoiding milk or foods high in vitamin D. Patients should be informed to seek medical advice if self-prescribing antacids for longer than 2 weeks.
Patients should avoid high-fat or spicy foods, caffeine-containing drinks, and alcohol while taking aluminum hydroxide.
