简要总结
The safety and efficacy at 100 mg once daily for oral dose of sitaxentan sodium were demonstrated in the STRIDE clinical trial program. Sitaxentan sodium was approved in the EU, Canada and Australia. In this study, the safety and efficacy after administrations of sitaxentan sodium at a dose of 100 mg alone or in combination with another medication will be investigated in Japanese PAH patients.
