Antimicrobials are precious agents for combating infectious diseases and had saved millions of lives throughout the world. However, the current trend of increasing antimicrobial resistance (AMR) has become a global health problem with increased morbidity and mortality in infectious diseases. Sri Lanka is not an exemption and face many health related issues with multidrug resistant (MDR) organisms. Currently there is a global effort in combating antimicrobial resistance. WHO extends its fullest support and plays a major role in motivating the countries to combat antimicrobial resistance with national action plans in place. Sri Lanka has initiated combating AMR with multisectoral collaboration, under one health concept. The development of the National Strategic Plan (NSP) 2017-2022 provides the roadmap to combat AMR.
