Osmosis video - Antacids: Nursing pharmacology

Antacids are medications that neutralize stomach acid. There are three types of antacids: aluminum hydroxide, magnesium carbonate, and calcium carbonate. Each type has its benefits and drawbacks.

Aluminum hydroxide is the most common type of antacid. It's available over-the-counter and is effective at neutralizing stomach acid. However, it can also cause constipation and has been linked to neurotoxicity. Magnesium carbonate is also available over-the-counter and is effective at neutralizing stomach acid. It doesn't cause as many side effects, but it can still cause diarrhea and abdominal pain. Calcium carbonate is another antacid that is available over-the-counter. It's effective at neutralizing stomach acid and can be taken long-term. However, it can cause constipation and gas.
