Document Summary
Pharmacology: the scieniic study of how drugs afect the nervous system and behavior. Drugs: chemical compounds administered to produce a desired change in the body. Psychoacive drug: substance that acts to alter mood, thought, or behavior; may be used to manage neuropsychological illness. Oral administraion is the safest, easiest, and most common route. Also the most complex; more barriers that the drug must cross to have its desired efect. Other methods, such as inhalaion or injecion, produce much faster efects as there are fewer barriers for the drug to pass. Intravenous (iv) injecion is the fastest route to the brain. Brain has a great need for nutrients and oxygen (it has a high blood low), which increases the risk of toxic danger. Capillaries in brain do not allow drugs to pass as easily as capillaries in rest of body. Caused by ight juncions between cells in the blood vessels of the brain.
