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: ["Disease", "Chemical"].

Please return the output as a JSON object of the format: {"Chemical" : ["Naloxone", ...], "Disease" : ["Hypotensive", ...]}. 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:

Hepatotoxicity of amiodarone. Amiodarone has proved very effective in the treatment of otherwise resistant cardiac tachyarrhythmias. The use of amiodarone has, however, been limited due to its serious side-effects. A patient with cholestatic hepatitis due to amiodarone treatment is presented below and a review of the hepatotoxicity of amiodarone is given. It is concluded that solid evidence exists of hepatic injury due to amiodarone treatment, including steatosis, alterations resembling alcoholic hepatitis, cholestatic hepatitis and micronodular cirrhosis of the liver. Patients receiving amiodarone should be regularly screened with respect to hepatic enzyme levels. Therapy should be discontinued on the suspicion of cholestatic injury or hepatomegaly.
