Variations in Drug Response
Using the knowledge you gained from the readings, evaluate how a typical drug,
when orally administered, may be handled differently by these two patients:
Ms. Jones is a 30-year-old female personal trainer that is 5’ 4” tall weighing 110lbs.
She regularly drinks socially and sometimes more than a bit when she meets with
her bi-weekly book club.
Mr. Smith is a 65-year-old software tester who is 6’ tall and weighs 235lbs. He drinks
only occasionally.
Assume no other significant medical history or issues with either patient. In your
analysis, compare how the two patients will metabolize the drug considering weight,
gender, distribution of body water and body fat, age, metabolic state, and alcohol
use. Explain how these factors impact the pharmacokinetics of the drug (half-life,
dosage, route of administration, and elimination of the drug). Evaluate the impact on
the risk-benefits analysis of the use of this drug.

Select a Topic for Your Critical Review
Select the topic for your Critical Review, which is due in Week Six, and briefly
analyze its key features and pathophysiology. You may select from any of the

disorder, depression, any of the anxiety disorders, PTSD, chronic pain disorders,
Alzheimer’s disease, Parkinson’s disease or other movement disorder, seizures,

treatment and not on other modes of treatment. Papers that discuss psychotherapy,
other than in passing, will not be given credit. Ask your instructor for clarification.
Explain your chosen psychiatric disorder in terms of neurotransmitter and receptor
theories. Describe the symptomology of the disorder and its relationship with the
neurotransmitters involved. Discuss the anatomic changes seen with the disorder.

resultant symptoms. Summarize the interaction(s) between the behavioral,
neuroanatomical, and neurotransmitter changes seen within the selected disorder.

Pharmacological and Physiological Antagonism
Prior to beginning work on this discussion, read the required chapters from the text
and review the required articles for this week. Alcohol and caffeine have nearly
opposite effects on behavior and the nervous system, yet these substances are not
used to treat overdose or addiction to the other.
Why not use caffeine to treat alcohol addiction? Analyze the issues of
pharmacological and physiological antagonism. Explain the receptor systems
involved and the central nervous system structures effects with regard to this
question. Frame your analysis in terms of drug action first and other consequences

Issues behind Addictive Drug Use
Prior to beginning work on this discussion, read the required chapters from the text
and review the required articles for this week. Humans have engaged in psychoactive
drug use, sometimes in formal (ceremonial) settings and sometimes recreationally,
since before recorded history. It has only been in the last century or so that abuse
and addiction have become large-scale problems. Using the literature and your own
insights into these issues, formulate an argument as to why the problem has reached
its current scale.
In your discussion, evaluate the employment of psychoactive drugs from the aspects
of a risk-benefits analysis and ethical considerations such as the risk of addiction
versus the cost of punitive action. Also explain purely pharmacological issues such
as pharma cokinetics and routes of drug administration and dose. If needed, include
factors such as supply, cultural attitudes to drug use, and the context of drug use.

Prior to beginning work on this discussion, read the required chapters from the text
and review the required articles for this week.
Taking on the role of the expert in the treatment of schizophrenia or depression, you

on the treatment of patients with these disorders. For this interactive assignment you
will create and upload a 5- to10-slide PowerPoint presentation as well as a fiveminute screen cast of the presentation to share with your peers.
For this presentation, select either schizophrenia or depression as the basis for your
presentation. Begin by creating your PowerPoint presentation. In the presentation,
include information which explains the neurotransmitter theory behind the disorder
and how the drugs used to treat the disorder affect those neurotransmitter
systems. Evaluate the risk and benefits of treating a patient with the most common
type of medication and of not using drugs to treat the patient.

Risks, Benefits, and Diagnosis
Prior to beginning work on this discussion, read the required chapters from the text
and review the required articles for this week.
The risk-benefit calculation for any drug assumes a correct diagnosis of the disorder.
Many investigators and clinicians feel the current epidemic of child psychiatric
disorders is largely due to inappropriate diagnosis. Evaluate the risk and benefits of
using psychoactive drugs in children correctly diagnosed with a disorder versus
those incorrectly diagnosed with a disorder.
Consider the risks and benefits of not treating (drug treatment) a child because he or
she is not correctly diagnosed with a disorder. In your evaluation summarize the
natural course of the disorder, the drug action on the neurotransmitter systems in
question, and the likelihood of short-term, long-term, and permanent positive and
negative effects of drug treatment. Make sure to take into account the ethical
dimension of this risk-benefit calculation.

weaknesses of using the medications to treat psychological disorders. Evaluate the
employment of psychoactive drugs in the treatment of disorders over the lifespan
from both an ethical and risk-benefits perspective. Summarize the theories of
psychiatric disease and the scientific rationale behind its treatment through the
employment of drug therapies. Explain what you believe to be the greatest
challenges in the use of psychoactive medications over the next several years.
