Lecture 3 Definitions Flashcards
Pain that is sudden in onset, usually subsides when treated, and typically occurs over less than a 6-week period.
Acute pain
Drugs that are added fir combined therapy with a primary drug and may have additive or independent analgesic properties or both.
Adjuvant analgesic drugs
Substances that bind to a receptor and cause a response
Agonists
Substances that bind to a receptor and cause a partial response that is not as strong as that caused by agonists
Agonists- antagonists (partial agonists)
What occurs when a particular pain drug no longer effectively controls a patient’s pain despite the administration of the highest safe dosages
Analgesic ceiling effect.
Drugs that bind to a receptor and prevent (block) a response, resulting in inhibitory or antagonistic drug effects.
Antagonists (inhibitors)
Pain that occurs between doses of pain medication
Breakthrough pain
A 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.
Gate control theory
Pain that results from a disturbance of function or pathologic change in a nerve
Neuropathic pain
Processing of pain signals in the brain that give rise to the feeling of pain.
Nociception
A subclass of sensory nerves (A and C fibers) that transmit pain signals to the CNS from other body parts.
Nociceptors
Pain that arises from mechanical, chemical, or thermal irritation or peripheral sensory nerves. Two subtypes of this are visceral and somatic.
Nociceptive pain
Analgesics that are structurally and functionally different from opioids.
Nonopiod analgesics.
A large, chemically diverse group of drugs that are analgesics and possess anti-inflammatory and antipyretic properties but are not corticosteroids.
Nonsteroidal anti-inflammatory drugs (NSAIDs)
Synthetic drugs that bind to opiate receptods to relieve pain.
Opiate analgesics
