GENERAL PHARMACOLOGY

13. What is Pharmacology?
(Greek “Pharmacon” – drug, “logos” - teaching)
Pharmacology is the study of the effects of chemical substances on living
systems, and the study of the effects of living systems on chemical
substances.

14. Pharmaceutical explosion
Nowadays there are over 350 thousand drugs
in the world which are used for different
diseases

15. 200 000 people in U.S.A. die from side effects of drugs
annually
76,6 billion $ are spared in U.S.A. annually to treat
complications attached to drugs usage

16. Take 5th place among causes of mortality on the Earth after
cardiac-vascular diseases, malignant tumors, lungs diseases,
traumas
Among stationary patients frequency of SE after introduction of
drugs makes 2-40 %

17. Doctors:
◦ Overdosing
◦ Administration of drugs to patients with allergy
◦ Mixing up names of the drugs
Medical nurses:
◦ Introduction of other drug by a mistake
◦ Violation of drug introduction regime
◦ Mistake in medical form

18. Branches/Divisions

19. Pharmacotherapeutics
It is the usage of drugs in everyday
medical therapy.
Pharmacokinetics—(what the body does to the drug)
◦ It is the branch of pharmacology that deals with drug dose, routes of
administration and absorption, distribution, metabolism and excretion.

20. The Life Cycle of a Drug
(pharmacokinetics)
Absorption
Distribution
Degradation
Excretion

21. Pharmacodynamics—(what the drug does to the body)
◦ It is a branch of pharmacology that deals with the mechanism of action,
pharmacological effects, indication and contraindication of use and adverse effects
of drugs.

22. What is Pharmacy?

2) 7-Chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one
◦Generic Name
◦ E.g 1) Acetyl- salicylic acid
2) Diazepam
◦Trade Name
◦ E.g 1) Aspirin
2) Valium

25. What is a PRESCRIPTION

◦The new drugs which are safer and more effective are included
◦The less useful and unsafe drugs are deleted.

27. Pharmacopoeias are published by many countries of the world
◦ Eg., British Pharmacopoeia – BP
◦ United states Pharmacopoeia – USP
◦ European Pharmacopoeia – EP
◦ International Pharmacopoeia – PI
◦ National Formulary NF

28. Pakistan National Formulary PNF
1. It is a publication of the drugs registered by Federal Ministry of
Health, Govt. of Pakistan to be marketed in the country
2. It includes all drugs manufactured in Pakistan and imported from
