The active ingredients in Alka-Seltzer are aspirin, sodium bicarbonate, and citric acid. Aspirin is a pain reliever and anti-inflammatory, while sodium bicarbonate is an antacid. Citric acid is a weak acid that helps to dissolve the aspirin and sodium bicarbonate.
When Alka-Seltzer is added to water, the sodium bicarbonate and citric acid react to form carbon dioxide gas. This gas causes the tablet to fizz and dissolve, releasing the aspirin into the water. The aspirin then dissolves into the stomach, where it can be absorbed into the bloodstream and relieve pain.
The antacid in Alka-Seltzer can also help to relieve heartburn and indigestion. Heartburn is a burning sensation in the chest that is caused by stomach acid backing up into the esophagus. Indigestion is a feeling of fullness, bloating, or discomfort in the stomach.
Alka-Seltzer is an effective over-the-counter medication for relieving pain, heartburn, and indigestion. It is available in tablet and powder form, and it can be taken with or without food.
