Q

Receptor

A

A molecular structure within or on the outer surface of a cell. Receptors bind specific substances (e.g. drug molecules) and one or more corresponding cellular effects occurs as a result of this drug-receptor interaction.

25
Steady State
The physiologic state in which the amount of drug removed via elimination is equal to the amount of drug absorbed with each dose.
26
Synergistic Effects
Drug interactions in which the effect of a combination of two or more drugs with similar actions is greater than the sum of the individual effects of the same drugs given alone.
27
Therapeutic Effect
The desired or intended effect of a particular medication
28
Therapeutic Index
The ratio between the toxic and therapeutic concentrations of a drug
29
Toxicology
The study of poisons. It deals with the effects of drugs and other chemicals in living systems, their detection and treatments to counteract their poisonous effects
30
Trade Name
The commercial name given to a drug product by its manufacturer (also called the proprietary name or brand name)
31
Active Transport
The active energy-requiring movement of a substance between different tissues via biomolecular pumping mechanisms contained within cell membranes
32
Diffusion
The passive movement of a substance (e.g. a drug) between different tissues from areas of higher concentration to areas of lower concentrations
33
Polypharmacy
The use of many different drugs concurrently in treating a patient, who often has several health problems.
34

39
Agonist
A substance that binds to a receptor and causes a response
40
Allopurinol

41
Analgesics
Medications that relieve pain without causing loss of consciousness.
42
Anesthesia
Loss of the ability to feel pain, resulting from the administration of an anesthetic drug or other medical interventions.
43
Anesthetics
Drugs that depress the central nervous system to produce diminution of consciousness, loss of responsiveness to sensory stimulation, or muscle relaxation.
44
Antagonist
A drug that binds to a receptor and prevents (blocks) a response.
45
Arthritis
Inflammation of the joints
46
Balanced Anesthesia
The practice of using combinations of drugs rather than a single drug to produce anesthesia
47
Chronic Pain
Pain resulting from any disorder that is often difficult to treat. Typically it is pain that lasts 3-6 months
48
Gate Theory
The most common and well described theory of pain transmission and pain relief.
49

A drug-induced state in which the CNS is altered to produce varying degrees of pain relief throughout the body as well as depression of consciousness, skeletal muscle relaxation, and diminished or absent reflexes.
50
Gout
Hyperuricemia; the arthritis caused by tissue build up or uric acid crystals
51
Inflammation
A localized protective response stimulated by injury to tissues that serves to destroy, dilute, or wall off both the injurious agent and the injured tissue.

57
Neuropathic Pain
Pain that results from a disturbance of function or pathologic change in a nerve.

60
Opioid Tolerance
A normal physiologic condition that results from long-term opioid use, in which larger doses of opiods are required to maintain the same level of analgesia and in which abrupt discontinuation of the drug results in withdrawal symptoms

A theory that describes the relationship between the lipid solubility of anesthetic drugs and their potency
62

The level of a stimulus that results in the perception of pain.
63
Pain Tolerance
The amount of pain a patient can endure without its interfering with normal function
64
