What is pharmacokinetics?
What an organism does to a drug
If a molecule binds to a receptor and prevents its activation…
it may be an antagonist drug
If a drug interaction is irreversible,
the effect of the drug can only be reversed if new receptors are
synthesised
The sum of all actions of a drug on a person is known as
pharmacodynamics
The speed, location, and length of action of a drug on a person are
determined by
pharmacokinetics
Once in the body, a drug will always
have the same mechanism of action in all people
The first stage of drug development is
chemical assay
Drugs are tested on healthy human volunteers in phase
0 only
Phases I, II and III testing for a new drug usually takes about
10 years
Randomised, controlled clinical trials take place in phase
III only
The regulatory body for drugs in the UK is the
