acute pain
pain that is sudden in onset and usually subsides when treated
adjuvent agent
a drug that is not a primary analgesic but has been shown to have independant or additive analgesic properties
agonist
a substance that binds to a receptor and causes a response
agonist-antagonist
a substance that binds to a receptor and causes that receptor to be stimulated and a response to occur while simultaneously binding to another receptor, occupying it but not stimulating it
analgesics
medications that relieve pain without causing loss of consciousness and sometimes referred to as painkillers
antagonist
an agent that binds to a receptor and prevents a response
chronic pain
persistent or recurring pain that is often very difficult to treat
gate theory
the most common and well-described theory of pain transmission and pain relief: it uses a gate model to explain how impulses from damaged tissues are sensed in the brain
narcotic analgesics

narcotic withdrawl (opiod abstinance syndrome)
the signs and symptoms associated with the abstinence from or withrawl of opiod analgesics when the body has become physically dependant on the substance
opiate and opiod analgesics
narcotic pain relievers that contain opium, are derived from opium, or are chemically related to opium
opioid tolerance
a common physiological result of long-term opiod use in which larger doses of opiods are required to maintain the same levels of analgesia
pain
an unpleasant sensory and emotional experience associated with actual or potential tissue dammage
pain threshold
the level of stimulus that results in the perception of pain
pain tolerance
the amount of pain a patient can endure without its interfering with normal function
partial agonist
a substance that binds to part of a receptor and causes effects similar to but less pronounced than those of a pure agononist
physical dependence
the physical adaptation of the body to the presence of an opiod or other addicting substance (i.e. barbiturates)
psychologic dependence (addiction)
a pattern of compulsive opiod use characterized by a continuous craving for the substance and the need to use it for effects other than pain relief
somatic pain
pain that originates from skeletal muscles, ligaments, or joints
superficial pain
pain that originates from the skin or mucous membranes
visceral pain
pain that originates from organs or smooth muscles
