ABSTRACT
Soshikokito is a Kampo formulation used in the treatment of bronchial asthma, especially in those patients with hot flushes and cold sensation in their feet. But there is also a description in classical textbooks for its usage for the treatment of tinnitus. We report two typical cases of prolonged tinnitus treated successfully with soshikokito. Case1was a 70-year-old woman who visited our clinic complaining of tinnitus, dizziness and insomnia. She had a history of bilateral otitis media in her childhood, and had been suffering from tinnitus after being operated for it. The tinnitus had worsened during the three months prior to her first visit to us. After 3 months' treatment with soshikokito with additional shisoyo, her symptoms improved, so much so that after 8 months, she could live her life normally. Case 2 was a 58-year-old man who presented with tinnitus, hearing disturbance and a sense of irritation. He also complained of insomnia and cold sensation in his limbs. After1month's treatment with soshikokito with additional shisoyo and bushi, most all of his symptoms resolved. In addition, we also evaluated the clinical efficacy of soshikokito for prolonged tinnitus, retrospectively, and found that it was effective in five out of the ten cases we treated with this formulation. Most of the successfully treated patients presented with hot flushes or cold sensation in their feet. These case reports suggest that soshikokito may be a useful formulation for the treatment of not only bronchial asthma, but also of prolonged tinnitus.
