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:

Seizure after flumazenil administration in a pediatric patient. Flumazenil is a benzodiazepine receptor antagonist used to reverse sedation and respiratory depression induced by benzodiazepines. Seizures and cardiac arrhythmias have complicated its use in adult patients. Overdose patients who have coingested tricyclic antidepressants have a higher risk of these complications. Little information exists concerning adverse effects of flumazenil in children. We report the occurrence of a generalized tonic-clonic seizure in a pediatric patient following the administration of flumazenil.
