A Case of Neurogenic Olfaction Disorder Successfully Treated with Reitakutsukito / 日本東洋医学雑誌

ABSTRACT

Reitakutsukito is a Kampo formulation that is applied for the treatment of olfaction disorder. There have been some reports that reitakutsukito improves nasal obstructions such as allergic rhinitis and chronic sinusitis, but none have reported a neurogenic olfaction disorder successfully treated with this formulation. We report a case of olfaction disorder that was neurogenic, successfully treated with reitakutsukito. The patient was a 43-year-old male. After being bruised on the head, he presented with olfaction disorder. He went to the otorhinolaryngology department at a university hospital and received a diagnosis of neurogenic olfaction disorder. However, he did not show any improvement. Fourteen months after the head trauma, he consulted our institution. We prescribed reitakutsukito for four weeks, and his subjective symptoms improved. Treatment with reitakutsukito for almost two years then resolved his symptoms. This case suggests that reitakutsukito could be a useful formulation for the treatment of not only respiratory olfaction disorder, but also neurogenic disorder.
