<b>Saikokaryukotsuboreito is Effective for </b><b>Blepharospasm : A Case Report </b> / 日本東洋医学雑誌

ABSTRACT

Blepharospasm is classified as a focal dystonia, and involves involuntary contraction of muscles such as the orbicularis oculi muscle and the corrugator muscle, which are associated with eyelid movement. Thus blepharospasm involves difficulties to eyelid opening. A 61-year-old woman came to our hospital complaining of a sense of discomfort of the eyes since a half year earlier. Blepharospasm was diagnosed based on current medical history and neurological examination. Oral saikokaryukotsuboreito was started and the blepharospasm improved gradually. After a week, oral treatment with one-third of the amount of shakuyakukanzoto was added and the blepharospasm further improved. The patient wanted to increase the dose of shakuyakukanzoto and to stop the saikokaryukotsuboreito. Once oral shakuyakukanzoto monotherapy was started, however, the blepharospasm worsened. Oral saikokaryukotsuboreito and low dose shakuyakukanzoto was started again, and her blepharospasm improved again.<br>The mechanism behind a focal dystonia such as blepharospasm is explained as a disorder of the basal ganglia motor loop. Saikokaryukotsuboreito is used for the diseases of the central nervous system. Thus there is the possibility that, here, saikokaryukotsuboreito improved a central nervous system disorder, and the blepharospasm. To our knowledge, this is the first report demonstrating that saikokaryukotsuboreito is effective for blepharospasm. It suggests that saikokaryukotsuboreito is a useful option for the treatment of blepharospasm.
