[Therapeutic Strategies for Myasthenia Gravis]

For years, the treatment of myasthenia gravis (MG) included high-dose oral steroids. This improved the mortality rate, but the adverse aspects of this treatment have become apparent. To overcome these statuses, an early fast-acting treatment strategy was advocated in the 2010s. Although this strategy improved the patients' quality of life, there are still many patients experiencing impaired activities of daily living. A certain number of so-called "refractory MG" patients also exist. Molecular-targeted drugs for MG have recently been developed. To date, three such drugs are available in Japan.
