Alka-Seltzer is an effervescent antacid and pain reliever owned by Bayer since 1978. First marketed by the Dr. Miles Medicine Company of Elkhart, Indiana, United States, Alka-Seltzer contains three active ingredients: aspirin (acetylsalicylic acid) (ASA), sodium bicarbonate, and anhydrous citric acid.[1] The aspirin is a pain reliever and anti-inflammatory, the sodium bicarbonate is an antacid, and the citric acid reacts with the sodium bicarbonate and water to form effervescence.[2]
It was developed by head chemist Maurice Treneer.[3][4] Alka-Seltzer is marketed for relief of minor aches, pains, inflammation, fever, headache, heartburn, stomach ache, indigestion, acid reflux, and hangovers while neutralizing excess stomach acid.[4] It was launched in 1931.[5]
Its sister product, Alka-Seltzer Plus, treats cold and flu symptoms. A wide variety of formulae, many using acetaminophen (paracetamol) instead of aspirin, are available under the sister brand.[6]
