Here is an example template:

# [medname] must be formatted as {generic (hyphenate if combination)} with {_route} if dramatically different from oral.
# for example: [budesonide_inhaler] because the oral form is used for EoE.
# similarly, [fluticasone-furoate_inhaler] - note the hyphenation used between the drug combos.
