derived from the greekword pharmakon
“drug poison”
pharmacology
related to pharmakos, the ritualistic sacrifice or exile of a human scapegoat or victim in Ancient Greek religion
pharmakon
is a brance of medicine, biology and pharmaceutical sciences (biomedical science)
pharmacology
-Father of American Pharmacology
-founded the first pharmacology department in the US University of Michigan (1890)
Jacob Abel
Greek physician lived the age of Pericles
(Descendant of God)
Hippocrates
he translated and used pharmacological tects
Nicholas Culpeper
medicines were compiled in a book called?
pharmacopeias
he was the first one to set up a pharmacology department in 1847 at the University of Tortu
Rudolf Buckheim
a medical science concerned with safe and effective use of medicine
pharmacy
study of techniques (preparation, compounding, dispensing,preserve and storage)
pharmacy
scientist who specializes in the study of pharmacodynamics, employing all kinds of biochemical, physiological and other techniques
pharmacologist
qualified and licensed who prepares and dispenses drugs
responsible for the manufacture of the dosage from drugs (e.g,tablets and drugs)
pharmacist
the study of dosage of amount of drugs given in the treatment of diseases
Porsology
how to take the medication as prescribed:a specific amount, number and frequency of doses over a specific period of time
dosage
refers to a specified amount of medication taken at one time
dose
a substance or preparation used in treating patient and diseases
medication / medicine
chemical substance that causes a change in an organisms physiology or psychology when consumed
drug name
describe the drugs chemical structure
chemical name
official, non propriety name of the drug and is universally accepted
-must be approved by FDA before marketed
-have fhe same active ingredient as brand named drugs but are less expensive due to less extensive, testing process
generic name
propietry name, chosen by the drug company to distinguish its product from competitors
- with symbol R inside a circle after the trade name ( for registered trademark,
Brand / Trade Name
name of the drug as it appears in the official references, the USP/NF, generally the same as generic name
Official Name
the process of drug movement throughout the body necessary to achieve drug action
pharmacokinetics
The Four process of pharmacokinetics
absorption
distribution
metabolism
excretion
the movement of the drug into the bloodstream after administration
drug absorption
a powdered form of medicine mixed with water
assuspension
a process wherein a drug in solid form disintegrate into small particles and combine with a liquid to form a solution
dissolution
the breakdown of an oral drug into a smaller particles
disintegration
absorption across the mucosal lining of the small intestine occurs through
passive transport
active transport
pinocytosis
does not require energy to move drugs across the membrane
passive transport
drugs moves across the cell membrane from an area of higher concentration o one of lower concentration
diffusion
relies on a carrier protein to move the drug across from an area of higher concentration to lower concentration
facilitated diffusion
requires energy, a carrier such as an enzyme or protein, to move the drug against a concentration gradient
acive transport
a process by which cells carry a drug across the membrans by engulfing the drug particles in a vesicle
pincytosis
the movement of the drug from the circulation to body tissues
drug distribution
What are the factors of influencing drug distribution
vascular permeability and permeability on cell membranes
regional blood flow and pH
Cardiac Output
Tissue Perfussion
Ability of the drug to bind tissue and plasma protein
it is also known as “Biotransformation”
- the process by which the body chemically changes drug into a form that can be excreted
drug metabolism
it is the primary site of metabolism
- metabolizes the lipid - soluble drug substance to a water-soluble substance for renal excretion
liver
elimination of drug from the body
drug excretion
it is the main route of drug excretion
kidney
the desirable response
primary effect
drugs are also excreted through where?
bile
lungs
saliva
sweat
breastmilk
the study of the effects of drugs on the body
pharmacodynamics
may be the desirable or undesirable
secondary effec
could be life threatening
adverse effect
study of the poisonous effect of the drug on the body
-deals with the adverse effects of substances on lining creatures
- these substances, maybe household, environmental, industrial and other substances
toxicology
