•The study of absorption, distributions, biotransformation and excretion of drugs•What the body do to the drugs•Fate of the drug in the body•Involved in how the concentration of drug in the body varies with time
Pharmacokinetics
•The study of biochemical and physiological effects of drugs and their mechanism of action•What the drug do to the body
Pharmacodynamics

Pharmacy :The scientific study about preparing, compounding and dispensing of drugs

The study of the drugs use in the prevention & treatment of disease
Some mechanism of actions of drugs :• Stimulate / depress biochemical or
physiological functions relief of symptoms
• Alter the course of disease
• Eliminate the pathogenic cells / organisms
Pharmacotherpeutics

Study relationship of genetics factors to variations in drug response (Brody, 1998)
Concerned with drugs responses that are governed by heredity (Laurence & Bennet, 1987) Inherited causal factors are :
• Biochemical – genes govern the production enzymes• Anatomical – mydriatics induced glaucoma in
patients with a shallow anterior eye chamber
Pharmacogenetics

Aspect of pharmacology that deals with AEs of drugs
Concerned with- drugs used in therapy- chemical household and industrial
intoxication
Toxicology

Chemical agent that effect the living process
Any substance used to modify physiological system OR pathological condition for the benefit of the recipient
So… what is drug?

Essential drugsmeet the health of the majority of
population
Generic drugsmarketed by any producers under non-
proprietary (=INN) / branded namesexp: paracetamol
Patent drugs (branded drug)pharmaceutical products marketed
under branded namesexp: Panadol, tempra
