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 [].

Abstract:

Yohimbine treatment of sexual side effects induced by serotonin reuptake blockers. BACKGROUND: Preclinical and clinical studies suggest that yohimbine facilitates sexual behavior and may be helpful in the treatment of male impotence. A single case report suggests that yohimbine may be used to treat the sexual side effects of clomipramine. This study evaluated yohimbine as a treatment for the sexual side effects caused by serotonin reuptake blockers. METHOD: Six patients with either obsessive compulsive disorder, trichotillomania, anxiety, or affective disorders who suffered sexual side effects after treatment with serotonin reuptake blockers were given yohimbine on a p.r.n. basis in an open clinical trial. Various doses of yohimbine were used to determine the ideal dose for each patient. RESULTS: Five of the six patients experienced improved sexual functioning after taking yohimbine. One patient who failed to comply with yohimbine treatment had no therapeutic effects. Side effects of yohimbine included excessive sweating, increased anxiety, and a wound-up feeling in some patients. CONCLUSION: The results of this study indicate that yohimbine may be an effective treatment for the sexual side effects caused by serotonin reuptake blockers. Future controlled studies are needed to further investigate the effectiveness and safety of yohimbine for this indication.
