Simple Summary: The inability of antimicrobials to kill or inhibit the growth of microorganisms
that they used to previously kill or inhibit leads to antimicrobial resistance (AMR). Overuse of
antimicrobials is usually associated with AMR; thus, global efforts have been made to systematically
monitor the availability and use of antimicrobials in humans and animals. In this study, a survey
was conducted from 2018 to 2020 to estimate the actual availability of different antimicrobials for
veterinary use in Nepal, targeting major government and non-government stakeholders relevant to
the authorization, production, and sales of antimicrobials. It was found that the total availability of
antimicrobials, including class I antibiotics that are critically important for the treatment of human
diseases, remarkably declined with the progression of time, meaning less antibiotics were used for the
treatment of animals in 2020 than in 2018 in Nepal. As animal health is closely connected with human
health, the data are very encouraging from a public health point of view. However, the awareness
and organized surveillance should be continued in the future.
Abstract: Antimicrobial resistance is a global public health problem and is primarily driven by the
widespread overuse of antibiotics. However, antimicrobial use data in animals are not readily avail-
able due to the absence of a national database in many developing countries, including Nepal. This
study was conducted to estimate the quantities of antimicrobials available in Nepal as an indicator of
their use in food-producing animals between 2018 and 2020. Data were collected through surveys
targeting major stakeholders: (i) the Department of Drug Administration (DDA), the Government of
Nepal (GoN) for the authorized antimicrobials for veterinary use in Nepal, (ii) veterinary pharma-
ceuticals for antimicrobials produced in Nepal, (iii) the DDA and Veterinary Importers Association
for antimicrobials bought by veterinary drug importers, and (iv) the Department of Customs, GoN,
for antibiotics sourced through customs. Data showed that in the 3 years, a total of 96 trade names,
comprising 35 genera of antibiotics representing 10 classes, were either produced or imported in
Nepal. In total, 91,088 kg, 47,694 kg, and 45,671 kg of active ingredients of antimicrobials were
available in 2018, 2019, and 2020, respectively. None of the antibiotics were intended for growth pro-
motion, but were primarily for therapeutic purposes. Oxytetracycline, tilmicosin, and sulfadimidine
were among the most-used antibiotics in Nepal in 2020. Oxytetracycline was primarily intended for
parenteral application, whereas tilmicosin was solely for oral use. Sulfadimidine was available for
oral use, except for a small proportion for injection purposes. Aminoglycosides, fluroquinolones,
nitrofurans, sulfonamides, and tetracyclines were mostly produced locally, whereas cephalosporins,
