However you cannot use human cells and
tissues to test drugs that affect multiple body
systems or the whole body system (blood)
2
The next stage is to test it on live animals ...
to see whether the drug works
to see how harmful the drug is
and to see what the best dosage is
there is a law that says you must test
a new drug on 2 different live animals
Annotations:
there is then the debate about the cruelty on animal testing and the fact its for the greater good of humans
3
if the the drug passes the
animal testings its then tested
on humans in clinical trials
optimum dose
dose of drug that is most effective
and has the least side effects
next the optimum dose is found and
the drug is given to healthy patients to
see if it has any harmful side effects
next, to test if the drug actually work, patients are
put in two groups. One group is given the actual new
drug and the other is given a placebo effect drug
then the drug is sold commercially to
help people in need
most of the clinical trials
are blind trials (with the
placebo drug) where the
patient doesn't know
a double blind trial is where
the doctor doesn't know
either
