Lecture Notes No. 4
Pharmacology and Pharmacokinetics
Part 1
Pharmacology
, Pharmacology
Study of drugs: structure, physical properties, chemical characteristics relevant to its activity as therapeutic agent
Drugs
any substance that causes a physiological change
agents for prevention, diagnosis, and treatment of diseases
Biotechnology
production of substances by genetic engineering
ex. production of antibiotics
Pharmaceutics
“What the pharmacist does to the drug”
preparation of dosage forms
Pharmacokinetics
“What the body does to the drug”
absorption, distribution, metabolism, excretion of drugs
Pharmacodynamics
“What the drug does to the body”
biochemical and physiological effects of drugs and MOA
