You will be shown an abstract from a biomedical research paper. Given this abstract, your task is to extract all unique entities of the following types: ["Brand", "UnapprovedDrug", "Drug", "DrugGroup"].

Please return the output as a JSON object of the format: {"Brand" : ["Aspirin", ...], "DrugGroup": ["Salicyclate", ...], "Drug": ["Phenobarbital", ...], "UnapprovedDrug": ["Heroin", ...]}. The keys should be entity types and values should be lists of extracted entities belonging to the corresponding type. If you cannot find entities belonging to a specific type, the value should be [].

Only output the JSON object and do not include any additional text.

Abstract:

Acid-catalyzed ethanolysis of temazepam in anhydrous and aqueous ethanol solutions. The benzodiazepines are a family of anxiolytic and hypnotic drugs. When taken concurrently with ethanol, a pharmacological interaction may occur, potentiating the central nervous system depression produced by either drug. In addition to this pharmacological interaction, this report describes a novel chemical reaction between temazepam (a benzodiazepine) and ethanol under acidic conditions similar to those found in vivo, resulting in a 3-ethoxylated product. Optimal conditions, kinetics, equilibrium, and the mechanism of this acid-catalyzed ethanolysis are reported. The results raise the possibility that the ethanolysis reaction may occur in the stomach of people who consume alcohol and 3-hydroxy-1,4-benzodiazepine on a regular basis. The acid-catalyzed ethanol-drug reaction is a relatively unexplored area and may alter the pharmacological action of some drugs.
