2. It is a branch of medicine & biology which deals with
the study of interaction between a drug (Or chemical
with possible therapeutic potential ) & the living
system i.e , body or microorganism.
The two main division of P’Cology are :-
 Pharmacokinetics .
 Pharmacodynemics .

4.  PHARMACOLOGY
PHRMACOKINETIC
PHARMACODINEMIC
ADME MOA
ABSORPTION MECHANISM OF
ACTION
DISTRIBUTION EFFECT
METABOLISM (CAMP-CYCLIC
ADRININE
EXCRETION MONOPHOSPHATE)

5.  It is a branch of P’Cology which deals with movement of a drug in the
body .
 Which include the process of Absorption ,Distribution ,Metabolism &
Excretion .
 Most of the drugs are
Absorb into the blood from the site of administration by passive
transport.
Distribution by binding with plasma protein.
Metabolism by liver.
At last they Excreted .

6.  It is a branch of P’Cology which deals with the study of
mechanism of action & result in physiological & biochemical or
behaviours effect of drug.(What the Body does to the Drug)
 Example :- Adrenaline blind to β-1 receptor of heart
Increase CAMP
ACTION
Increase Calcium Ion in Heart Muscles
Increase Force of Contraction of heart
EFFECT
Increase B.P

7.  Poisons are substances that cause death, injury or
harm to organs, usually by chemical reactions or
other activity on the molecular scales, when an
organism absorbs a sufficient quantity.
 The substance that disturb normal Physiological
,Biological & Behavioural Activities , Poison is fatal.
 When it is absorbed in the body in a sufficient
quantity drug at high dose can act as poison.

8. It is a branch of biology , chemistry &
medicine (more specifically Pharmacology)
which deals with the study of adverse
effect of chemical on living organism.

9. It is a branch of P’cology which deals with the
study of therapeutic uses & effect of drug in
patients.
OR
Pharmacotherapeutics is a branch of
Pharmacology, which is defined by Merriam-
Webster as “the study of the therapeutic uses
and effects of drugs” this is a study of
beneficial and adverse effects of drugs.

10.  It provide the rational basic for the therapeutic use of
drug.
 To study of disease /disorder (Pharmacology)
 To study of Pharmacodynemics.
 To study of Pharmacokinetic.(ADME)
 Clinical Pharmacology & Therapeutic.

11. Posology :-
It is the study of dosage & dose schedule.
Toxicology :-
It is a branch of biology , chemistry & medicine (more
specifically Pharmacology) which deals with the study of
adverse effect of chemical on living organism.
Pharmacovigilance :-
It is Pharmacological science nothing to detection ,
assessment , understanding & prevention of adverse
effect particularly long term & short term side effect
of drug.

12. Chemotherapy :-
It is a branch of P’Cology , Chemotherapy is a drug
treatment that uses powerful chemicals to kill fast-
growing cells in your body.
Pharmacy :-
Pharmacists are healthcare professionals with
specialized education and training who perform
various roles to ensure optimal health outcomes for
their patients through the quality use of medicines.
Pharmacists may also be small-business proprietors,
owning the pharmacy in which they practice.
