Many acute-attack treatments depend on injectable or intravenous delivery, which can delay care in low-resource or emergency-limited settings. FDA approval of Ekterly (sebetralstat), the first oral plasma kallikrein inhibitor for acute HAE attacks in patients aged 12+, marks a major management shift. This editorial explains the scientific rationale, reviews KONFIDENT trial results, and evaluates safety, efficacy, and clinical fit, highlighting faster onset and oral independence. It also discusses CYP3A4 interactions and limited evidence in pregnancy or hepatic impairment.","Editorial  \nNovel drug approval by the FDA: Ekterly(Sebetralstat), oral plasma kallikrein inhibitor fortreating acute attacks of hereditary angioedema  \nGulalai, BDSa , Syeda Aiman Miraj, MBBSb , Raghabendra Kumar Mahato, MBBSc ,*  \n# Abstract\n\nHereditary angioedema (HAE) remains a challenging, potentially life-threatening disorder driven by dysregulated plasma kallikreinactivity and excessive bradykinin generation. Despite major therapeutic advances, most available treatments for acute attacks relyon injectable or intravenous agents that impose barriers to timely administration, particularly in low-resource or emergency-limitedsettings. The recent FDA approval of Ekterly (sebetralstat), the first orally administered plasma kallikrein inhibitor for acute HAEattacks inpatients aged 12 years and older, represents a landmark shift in the management of this rare disorder. In this editorial, wehighlight the scientific rationale behind sebetralstat, summarize key findings from the KONFIDENT clinical trial, and evaluate itssafety, efficacy, and clinical applicability. Ekterly demonstrated a significantly faster onset of symptom relief, earlier reduction inattack severity, and more rapid attack resolution compared with placebo, marking a meaningful improvement over existingtherapies. Its oral administration represents a significant therapeutic advancement, allowing patients to manage acute attackspromptly and independently without reliance on clinical facilities. This is particularly advantageous in settings with limited access tointravenous therapy, cold-chain storage, or timely emergency care. The novelty of our work lies in synthesizing emergingmechanistic insights, regulatory developments, real-world applicability, and clinical trial performance into a unified evaluation of thefirst oral short-term prophylactic and on-demand kallikrein inhibitor for HAE. Through a detailed appraisal of its therapeutic efficacy,safety profile, and pharmacologic constraints -including clinically relevant interactions with CYP3A4 modulators andthe lack ofevidence in pregnant patients or those with hepatic impairment,this editorial emphasizes Ekterly’semerging role as an importantand potentially transformative addition to HAE management.The approval of sebetralstat signals a new era of convenient, rapid -acting, accessible treatment for HAE, with the potential to reduce emergency visits, enhance patient autonomy, and improvequality of life. Continued surveillance, long-term safety studies, and global access initiatives will be essential to maximize its public -health impact and ensure equitable availability of this breakthrough oral therapy.  \nKeywords: Bradykinin, CYP3A4, Ekterly, hereditary angioedema, Sebetralstat  \nDear Editor,  \nHereditary angioedema (HAE) is a rare genetic disorderinherited in an autosomal dominant pattern, resulting frommutations in the gene responsible for producing C1 esteraseinhibitor (C1-INH).
