Alka-Seltzer (Acetylsalicylic acid/Citric acid/Sodium bicarbonate) is an over-the-counter medication used to relieve symptoms of excess stomach acid like heartburn, acid indigestion, and upset stomach when accompanied by headache or body ache. Without treatment, the extra gastric acid can lead to peptic ulcers in the stomach and intestine. The drug also treats upset stomachs with headaches from overindulgence in food or drink. Alka-Seltzer also treats headaches, body aches, and pain alone. The active ingredients in Alka-Seltzer are acetylsalicylic acid, citric acid, and sodium bicarbonate. Acetylsalicylic acid (Aspirin) belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by blocking proteins that cause inflammation in the body to relieve pain and swelling. Citric acid and sodium bicarbonate are antacids. They work by neutralizing the acid in the stomach to relieve indigestion and upset stomach.
