Psychopharmacology Flashcards
____ (____) ____ are chemicals that interact with the central nervous system in a way that produces a change in mood, consciousness, perception, and/or behavior. These drugs exert their effects in a number of ways — i.e., by _________________________________________.
Psychoactive (Psychotropic) Drugs; increasing or decreasing the production or reuptake of neurotransmitters. by increasing or preventing the release of neurotransmitters, or by facilitating, mimicking, or blocking the effects of neurotransmitters at receptor sites.
____ ____: The following terms are used to describe the ____ of the ____ ____: Agonists; Inverse Agonists; Partial Agonists; Antagonists.
Drug Effects; Effects of the Psychoactive Drugs
____ produce effects similar to those produced by a neurotransmitter. ____ ____ exert their effects by mimicking the effect of a neurotransmitter at a receptor site, while ____ ____ attach to a binding site on a receptor cell (a site other than the one used by the neurotransmitter) and facilitate the action of the neurotransmitter.
Agonists; Direct Agonists; Indirect Agonists
____ ____ produce an effect opposite the effect produced by a neurotransmitter or an agonist.
Inverse Agonists
____ ____ produce effects that are similar to (but less than) the effects produced by a neurotransmitter or an agonist.
Partial Agonists
____ produce no activity in the cell on their own but, instead, reduce or block the effects of a neurotransmitter or agonist. ____ ____ exert their effects by attaching to a neurotransmitter’s receptor site, while ____ ____ attach to a binding site on a receptor cell (a site other than the one used by the neurotransmitter) and interfere with the action of the neurotransmitter.
Antagonists; Direct Antagonists; Indirect Antagonists
____ and ____ ____: ____ -____ ____ are a common cause of hospital admissions for people over the age of 65. Factors that contribute to these problems include the use of ____ ____, noncompliance with ____ ____, and ____ or ____ ____ to ____ ____. Changes in sensitivity are due to several factors including ____ -____ ____ in ____ ____, ____, ____, and ____.
Drugs and Older Adults; Medication-Related Problems; Multiple Medications, Noncompliance with Medication Regimens, and Decreased or Increased Sensitivity to Drug Effects; Age-Related Changes in Drug Absorption, Distribution, Metabolism, and Excretion
An age-related decrease in ____ or reduction in renal functioning may extend the half-life of some drugs (e.g., benzodiazepines), resulting in an increased risk for ____. (____ -____ refers to the time it takes for the plasma concentration of the drug to drop by 50%.) Because of the increased risk for adverse drug effects, a general rule when prescribing drugs for older adults is to “____ ____ and ____ ____ “ — i.e., begin with a low initial dose and, if necessary, increase the dose gradually.
Metabolism; Toxicity; Half-Life; Start Low and Go Slow
____ and ____ /____: Research has identified some cross-ethnic differences in responses to ____ ____ and has related these differences to a number of ____, ____, and ____ factors.
Drugs and Race/Ethnicity; Psychotropic Medications; Pharmacokinetic, Pharmacogenetic, and Pharmacodynamic
Regarding ____, some ethnic dissimilarities in drug response have been linked to differences in ____. For example, in comparison to Caucasians, higher proportions of Asians and, to a somewhat lesser degree, African-Americans are slower or poorer metabolizers of specific ____, which explains why they are more sensitive to the therapeutic and side effects of certain drugs such as neuroleptics, benzodiazepines, lithium, and some antidepressants.
Pharmacokinetics; Metabolism; Isoenzymes
Because of the ethnic differences, the experts propose that the best approach when prescribing a new drug for an Asian or African-American patient is to be4n with a ____ ____ and ____ ____ ____ until the ____ ____ ____ ____.
