Increase in Disease Awareness and Early Diagnosis

Increasing awareness about PAH is significantly contributing to the growth of Japan's PAH drugs market. Historically underdiagnosed due to its non-specific symptoms, PAH is now being recognized more widely by both patients and healthcare providers. Public awareness campaigns led by health organizations, hospitals, and pharmaceutical companies are educating the public and medical professionals about the importance of early diagnosis and timely intervention. In parallel, advancements in diagnostic technologies, including echocardiography, right heart catheterization, and biomarkers, have enabled earlier detection of the disease, driving greater demand for PAH therapies. In addition to this, the number of diagnosed PAH patients in Japan is gradually increasing, underscoring the positive impact of heightened awareness and early detection. This growing recognition is fueling the demand for treatment, further catalyzing the market's expansion.
