Alka-Seltzer is an effervescent antacid and pain reliever first marketed by the Dr. Miles Medicine Company. It was developed by Maurice Treneer, head chemist at Miles, in Elkhart, Indiana.〔(Origin of Everyday Things ) by Think Books (editor), Sterling Publishing Company, Inc., Nov 28, 2006 page 12. Retrieved October 21st, 2012〕〔(Google Books ), Sold on Radio: Advertisers in the Golden Age of Broadcasting By Jim Cox pp 197-199 ISBN 978-0-7864-3391-9 May 23, 2008〕 Alka-Seltzer is marketed for relief of minor aches, pains, inflammation, fever, headache, heartburn, stomachache, indigestion, and hangovers, while neutralizing excess stomach acid.〔(Google Books Sold on Radio: Advertisers in the Golden Age of Broadcasting ) By Jim Cox pp 197-199 ISBN 978-0-7864-3391-9 May 23, 2008〕 It was launched in 1931.〔(The book of answers: the New York Public Library Telephone Reference Service's most unusual and entertaining questions ) By Barbara Berliner, Melinda Corey, George Ochoa. Simon and Schuster, 1992〕 A spin-off of Alka-Seltzer made to relieve colds and flu, Alka-Seltzer Plus, was later introduced. A short-lived antacid non-aspirin variant, Alka-Mints, was introduced in 1994 and discontinued in 1997. Alka-Seltzer is currently owned by Bayer Schering Pharma AG, Germany. The name "Alka-Seltzer" has been extended to incorporate an entire line of medications sold over the counter and taken by means of rapidly dissolving tablets that form a carbonated solution in water. The brand is sold in North and Central America (and the Caribbean), as well in Asia-Pacific. In the 1980s and 1990s, Bayer attempted to introduce the brand in Europe and South America with little success, withdrawing them after a few years. In these markets (and the rest of the world), the company has reentered the antacid market in recent years under the name "Rennie". ==Composition== Alka-Seltzer contains three active ingredients; aspirin (acetylsalicylic acid), sodium bicarbonate, and anhydrous citric acid.〔(【引用サイトリンク】title=Alka Seltzer Directions of use, Sodium & Aspirin content - Alka Seltzer relief from Headaches, Migraine & Upset stomach )〕 The aspirin is a pain reliever and anti-inflammatory, and the sodium hydrogen carbonate and citric acid form an antacid.〔(【引用サイトリンク】title=Alka-seltzer original )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Alka-Seltzer」の詳細全文を読む スポンサード リンク
