How drugs get into, are
distributed, and do their job in the
body
Drugs undergo a complex journey within the body starting from their entry to their final destination where they exert their intended effects. Initially, drugs are often administered orally and must be small enough to be absorbed through the stomach lining.
How drugs get into, are
distributed, and do their job in the
body
circulatory
the deug travels to the liver and to the targeted
area through the circulatory system.
small intestine
the drug moleculess have to be small enough
to be absorbed through the intestine lining
if the drug is not fully absorbed in the
stomach,it moves to the small intestine lining
stomach and stomach acid
the drug also has to to a small enough molecule
to be absorbed by the stomach lining
the stomach however may destory the drug as
a result. this is when the drug is chosen to be
adminstered through inhalation or injeaction
the drug is dissoled in the stomach by the
stomach acid. the stomack lining absorb the
drug into the bloodstream
liver
whenthe drug has entered the bloodstream
it travles to the liver where it could possibly be
dstroyed by the enzymes produced. this
is when another methood of getting drugs to the
targetd area
fat
fat in the bloodstream may be a
barrier to the drug getting to the
targeted area as it may hijack the drug molecules.
enzymes
the enzymes may not be helful in the liver
as the enzymes produced in the liver may
be destroyed by them
the enzymes are helful to targeting to
area that the drug is intended for
receptors
the drugs know where to go when the recetors
that target the organblatch onto the drug
molecules
side effected can happen when the drug molecules
bind receptors that are not the intended
target
protein
protein can hijack the drug molecule which
prvents the drug from going where it is
intended to go
Subtopic
cells
the cells soak up the drug and
the drug does what it is intended
to do ex. relieve pain.
