absorption,destribution,metabolism and excretion
of drugs.
• The entry of drug in the body until its excretion,
the study of what happens to drug in the body is
known as pharmacokinetics.
• Pharmacodynamics:It deals with the study of
MOA and pharmacological effect of drug.

i.e.economic aspects of drugs used therapeutically.
• Pharmacogenomics:It is a branch of genetics which
deals with the use of pharmacogenetic information in
selecting drugs for a person.
• Pharmacoepidemiology:It is the study of both useful
and adverse effects of drugs on large number of people.
• Pharmacovigilence:It is a branch of science which
deals with the study of adverse drug effect in the body.
• Clinical pharmacology:It evaluate the
