INTRODUCTION
 Pharmacology is the branch of science of
drugs which deals with the interaction of
exogenously administered chemical
molecules with living system.
 It is derived from greek word ‘pharmakon
means drug’ and ‘ logos means science or
knowledge’.
 Any single chemical substance which can
produce a biological response is called drug.
 It includes the study of mechanism of action ,
interactions , contraindications , adverse reactions,
side effects of drugs with in the living system.
 It explains about the pharmacodynamics [what
the drug does to the body] , and pharmacokinetics
[what the body does to the drug] .
 It also explains the different actions of drugs
in different people based on their body
responses to the drug.
HISTORY OF PHARMACOLOGY
 The origin of pharmacology is not clearly
known.
 In earlier most drugs were crude natural
products of unknown composition and limited
efficacy .
 The earlier people know the knowledge of
crude drugs and their uses in diseases .
 So , the early pharmacology focussed on
herbalism and natural substances , mainly plant
extracts .
 Pharmacology as an experimental science was
intiated by Rudolf buchheim who founded the
first institute of pharmacology in 1847 in
Gemany .
 Although the oswald schmiedeberg student of
buchheim influenced to study of medicines
into an experimental science .
 In 19th century Oswald schmiedeberg [1838-1921]
,regarded as ‘Father of pharmacology’ .
 Together with oswald many followers like J Langely,
T Frazer , P Ehrlich , AJ clark , JJ abel to enunciate
some of the fundamental concepts in
pharmacology .
 Since then the drugs have been purified ,
chemically characterized and a wide variety of
highly potent and selective new drugs have been
developed .
 The mechanism of action including molecular
target of many drugs have been illuminated .
