Ladies and gentlemen, my
name is Sven Stegemann.
I'm from the Graz
University of Technology,
Institute of Process and
Particle Engineering
in Graz, Austria.
I will give you an introduction
to the routes of drug delivery.

You see the definition.
We'll talk about the
route of drug delivery as
a combination of routes of
administration and
drug delivery.
The route of administration
is basically
the path by which
a drug molecule,
biologic or any other substance,
is taken into the body
or the site of action.
Drug delivery is a path by which
this active is released
in terms of rate,
time, place in the body,
in a very controlled
or desired way.

You see the routes
of administration,
which we can basically
classify into
six major routes
of administration.
The first is the oral
(enteral) route,
which is going
through the mouth.
The parenteral route, mainly
includes injection or infusion,
which is injecting by
a system of a needle
directly into the body,
through the arteries, into the
veins, into muscle tissue.
The next route of administration
is the cutaneous
(transdermal) route,
everything which is going on or
through our external skin.
Pulmonary and nasal delivery
is through our
respiratory tract,
either directly to
the lung or our nose.
The mucosal route is when we
apply drug systems
to any mucosa,
which is basically a wet
membrane that we have
in our mouth, in the
vagina and so on.
The last one is really
the emerging routes of
drug administration,
which is through
advanced therapy,
cell therapies, CAR-T
cells, and so on.
