Abstract

We investigated the stability of “Chloral Hydrate Syrup” by 1H-NMR spectrometry and spectrophotometry.“Choloral Hydrate Syrup” is composed of 4%(w/v) chloral hydrate, 50%(w/v) simple syrup and 2%(w/v) pineapple flavor. When “Chloral Hydrate Syrup” was kept in the dark and cold conditions, chloral hydrate was found to be stable for at least 2 weeks. No changes in the smell and taste of “Chloral Hydrate Syrup” were observed. However, the color was fugitive, and 80% of original color was lost within a week even in the dark and cold conditions.The Pharmacological effects of “Chloral Hydrate Syrup” given for 25 infant patients, who had been hospitalized in Toyama Medical and Pharmaceutical University Hospital between September and November 1997, were evaluated clinically. “Chloral Hydrate Syrup” showed a certain, hypnotic effect in 24 out of 25 patients. These results suggest that “Chloral Hydrate Syrup” is useful as a hospital hypnotic preparation.
