Pharmacology Using Drugs Therapeutically Chapter 5

The drug's main action for which it was prescribed by the physician is called the therapeutic(beneficial) effect
Drug actions that are undesirable but not unexpected are called side effects
Severe side effects are called adverse effects
Poisonous effects of a drug are called toxic effects
An unusual or exaggerated allergic reaction to a medication is called anaphylaxis
Undesirable interaction of drugs is called incompatibility
A unique reaction to a medication is called an idiosyncrasy
A drug that deactivates another drug is called an antagonist
Two drugs combining to produce an effect greater than the independant effects of each is called synergism
An example of a beneficial synergistic effect is Tylenol #3 which contains acetaminophen & codeine
Together they provide more analgesic effect than either can separately
An example of an undesirable synergistic effect is the combination of antihistamines and alcohol which can cause unusual drowsiness
The synergistic effect of tranquilizers and alcohol can cause death
