Until now, injectable glucagon was the only available treatment used in the management
of severe hypoglycemia wherein glucagon had to be prepared in several steps before

route of drug delivery. nasal glucagon (NG) now serves an efficient, safe, easy-to-administer,
and a favorable substitute to glucagon injections. This ready to use device stand
in clear contrast to overcome the limitations associated with the currently available
glucagon preparations has emerged a key advancement in the management of severe hypoglycemia
in adolescents and children with type 1 diabetes. NG is now being developed and studied
in other countries as well to meet the unmet need for an easy and convenient glucagon
administration. This review covers the basic information of nasal glucagon, trials
on nasal glucagon in children and adults and its potential uses, limitations, and
future scope in practice.
