The burden of GERD has been steadily rising in Indonesia, largely driven by changing dietary habits. According to the Indonesian National Guidelines for GERD Management (2022), the general population prevalence is estimated at approximately 9.35%. Market research firm IQVIA reports that the Indonesian anti-ulcerant market reached approximately IDR 2.5466 trillion (USD 164.3 million) in 2025, maintaining a steady annual growth rate of around 6%. Furthermore, tertiary-care hospital data indicate that 55.4% of GERD patients present with erosive esophagitis, underscoring the critical need for accurate diagnosis and prompt, effective early intervention in clinical practice.

Prof. Ji Won Kim, M.D., Ph.D., President-Elect of the Korean Gastroenterology Association, delivers remarks at the launch of Fexuprazan in Indonesia in Jakarta. He said that the official launch of Fexuprazan marks a significant milestone and expressed his hope that fexuprazan will contribute to improving the quality of life of patients with GERD in Indonesia.

Ari Fahrial Syam, MMB, SpPD, K-GEH, FACG, FACP, Chairman of Pengurus Besar Perkumpulan Gastroenterologi Indonesia (PB PGI) and Professor at Cipto Mangunkusumo National General Hospital, noted, “Indonesia has a high proportion of GERD patients presenting with erosive esophagitis, creating a strong clinical demand for next-generation therapies capable of rapid and robust acid suppression from the onset of treatment. Establishing evidence-based prescribing guidelines optimized for the local healthcare environment—supported by Indonesian clinical data—holds tremendous academic value.” 

During the media session for the launch of Fexuprazan in Indonesia by PT Daewoong Pharmaceutical Indonesia at Jakarta, 18 September 2026, Prof. Dr. dr. Ari Fahrial Syam, MMB, Sp.PD, K-GEH, FACG, FACP, Chairman of the Executive Board of the Indonesian Gastroenterology Association (PB PGI), stated, Indonesia has a fairly high proportion of GERD patients with erosive esophagitis. This condition indicates a clinical need for a new-generation therapy capable of providing rapid and strong acid suppression from start of treatment.

Highlighting real-world clinical experience and trial data from South Korea, Prof. Ahn Ji Yong, Professor of Gastroenterology at Asan Medical Center and the University of Ulsan College of Medicine, explained, “In South Korea, P-CAB therapies were introduced sequentially to address the unmet needs of conventional PPIs, allowing us to accumulate extensive clinical prescribing experience. In a Phase 3 study evaluating 263 Korean patients with erosive esophagitis, fexuprazan demonstrated a 99.1% endoscopic healing rate at Week 8, confirming significant clinical efficacy.” 

Prof. Ahn Jiyong,M.D, Ph.D., Professor of Gastroenterology at Asan Medical Center, explained during the media session for the launch of Fexuprazan in Indonesia by PT Daewoong Pharmaceutical Indonesia that the use of P-CABs in South Korea continues to grow in response to several clinical needs that are not fully addressed by proton pump inhibitor (PPI) therapy.
