Description
Benorylate is the acetaminophen ester of
acetylsalicylic acid, designed to provide a less
irritating form of aspirin. Gastrointestinal blood
loss in patients taking benorylate is less than that
during therapy with soluble aspirin. Benorylate has been found to be as effective as aspirin for
the treatment of chronic rheumatic disorders.
Originator
Benortan,Winthrop,Switz.
Uses
Benorilate is a codrug of Acetylsalicylic Acid (A187780) and Acetaminophen (A161220) and is used as an anti-inflammatory and antipyretic medication.
Definition
ChEBI: Benorilate is a carbonyl compound.
Manufacturing Process
Example 1: 65 grams of N-acetyl-p-aminophenol were slurried with 400 ml of
water and cooled to 10°C. 125 ml of 20% sodium hydroxide were slowly
added to the mixture with stirring, the temperature being maintained between
10°and 15°C. To the solution obtained, 75 grams of acetyl salicoyl chloride
were added with vigorous stirring over a period of 1/2 hr, the solution being
maintained at a temperature of about 10°C. Towards the end of the reaction
the pH was checked and adjusted to greater than 10 by the addition of a
small amount of 20% sodium hydroxide. After all the acid chloride had been
added, vigorous stirring was continued for half an hour during which time the
crude product separated out. This product was filtered off, washed thoroughly
with water and recrystallized from ethanol.
Example 2: 65 grams of sodium N-acetyl-p-aminophenol were slurried with
500 grams of dry benzene and 80 grams of acetyl salicoyl chloride added. The
mixture was heated under reflux for four hours and filtered hot. The excess
benzene was removed under vacuum and the crude acetyl salicyclic acid ester
of N-acetyl-p-aminophenol crystallized from ethanol.
