Q

Currently, physicians are more likely to prescribe second- generation antipsychotics instead of first-generation anti- psychotics. Why does this occur? Does the scientific evi- dence support the view that second-generation antipsychotics are superior to first-generation antipsychotics?

A

The prevailing wisdom among physicians who prescribe second-generation antipsychotics is that there are reduced side effects with these drugs. However, recent large clinical trials have revealed that there appears to be little difference in effectiveness or side effects for either antipsychotic drug class. Both types control symptoms, and both may lead to serious side effects.

postmarketing testing

31

80%

32
Q

Fred and Jim both are experiencing symptoms of psychosis. A physician determined that the cause of Fred’s psychosis is drug-induced since he had recently taken a large dose of cocaine. A physician determined that the cause of Jim’s psychosis is due to the mental disorder of schizophrenia. What is the probable prognosis for these two individuals?

A

Fred’s prognosis is better than Jim’s prognosis. The cause of Fred’s psychosis is correctable. Once the cocaine leaves Fred’s body, his psychotic symptoms should abate, and he may not even need treatment with an antipsychotic drug. By contrast, Jim’s prognosis is more serious given that schizophrenia is typically a lifelong mental disorder that will probably require continuous antipsychotic drug treat- ment to keep symptoms under control

33
Q

Your mother goes to the pharmacy to fill a prescription. The pharmacist tells her that the brand-name drug will cost $32, while the generic version costs $4. She wants to save the money and take the generic, but she is worried that the brand-name drug will work better. What would you say to her?

A

You would tell her that the generic drug is a copy of the brand-name drug. The Food and Drug Administration (FDA) ensures that all generics are the same in terms of safety, strength, route of administration, quality, perfor- mance characteristics, intended use, and how dosing should occur.

59
Q

What is the relationship between a country’s socioeconomic status and its rate of depression? Why might this relation- ship be observed?

A

Lower- to middle-income countries tend to have lower rates of depression than high-income countries. This counterintuitive relationship may be observed because for people living in developing countries, such as India and China, many individuals are poor. In the United States, there is great affluence and also great poverty. The poor in the United States may face the stark reality of their situation more often.

60
Q

Explain the relationship between antidepressant drug treatment and neurogenesis.

A

Depression, anxiety, and chronic stress can induce brain damage, as evidenced by neuronal death observed in struc- tures of the brain such as the hippocampus. Antidepressant drug treatment induces neurogenesis in the hippocampus. With several weeks of drug treatment, new neurons will form in this region of the brain. The timing of neurogenesis coincides with the long time that antidepressants must be taken before the patient reports beneficial symptom relief.

Mildred is 70 years old and has recently developed symptoms of generalized anxiety disorder. What medication would her physician likely prescribe for her? Be specific about ideal duration of action and dose when explaining your answer

A

Given Mildred’s age, her physician would likely prescribe a
short-acting benzodiazepine, but at a dose that would be less than would be prescribed for a younger patient. This choice would reflect the reduced metabolism capacity in elderly patients, especially for benzodiazepines.

68

69
Q

Elton has a prescription for a benzodiazepine. He also smokes, drinks alcohol, and sometimes snorts cocaine. Which recreational drug is most risky when combined with the benzodiazepine, and why?

A

Alcohol is the most risky drug to combine with the benzodiazepine because both are sedatives. When combined, they could suppress respiration, which could lead to a coma or even death.
