Tylenol is an American brand of drugs advertised for reducing pain, reducing fever, and relieving the symptoms of allergies, cold, cough, and flu. The active ingredient of its original, flagship product, acetaminophen (commonly known by its INN paracetamol elsewhere in the world), is marketed as an analgesic and antipyretic. Like the words 'acetaminophen' and 'paracetamol', the brand name is derived from the chemical name for the compound, N-acetyl-para-aminophenol (APAP). The brand is owned by McNeil Consumer Healthcare, a subsidiary of Johnson & Johnson. James Roth, a U.S. gastroenterologist, advocated paracetamol as a gastric-friendly alternative to aspirin, which can irritate the stomach when taken without food. Roth was also principal consultant to McNeil Laboratories. In 1953, McNeil Laboratories introduced Algoson, a preparation containing paracetamol together with sodium butabarbital, a sedative.
