Selected disorder: PTSD (POST TRAUMATIC STRESS DISORDER)

This week, please focus on the pharmacological (drug) treatment of your selected disorder. Other modes of treatment are not the focus of our class. For instance, papers that discuss psychotherapy, other than in passing, will not be given credit. In your paper, please be sure that the following aspects of your topic are discussed:

Describe the key classes of drugs used to treat your selected disorder. A class of drug usually indicates the drugs mechanism of action (how the drug exerts is pharmacological effects on the body). Be sure to explain why this class of drugs or classes of drugs would be helpful in treating your selected disorder by describing the action of these drugs on the neurotransmitter system(s) involved in the disease process. Within each class of drug, there will be one or more drugs available on the market for use in clinical management, and examples of these should be included in your discussion.
Analyze and describe the agonist-antagonist activity of the drugs, and the receptor types and subtypes on which the drugs will exert their pharmacological action. Indicate if these drugs will reverse or slow the disease process, or if they will only help ameliorate symptoms.
Close your paper with an analysis of the risk-benefit of drug use for your selected disorder. Include a discussion of how the drug class(es) would be typically used, what expected benefits would be obtained from drug use, and what common drug side effects might occur.
For Week 2, please research a minimum of three peer-reviewed or scholarly articles published within the last five-to ten years. These references are in addition to those used in the Week 1 written assignment, and should focus on pharmacological (drug) treatment of your selected disorder. These sources should provide evidence-based information to help support your analysis, focusing on the aspects described above. Be sure to cite your sources in your paper and include them on your References page. You may utilize required or recommended course materials in your work, but these will not count towards the reference requirements; however, you may cite and reference the DSM-5 as one of your sources used for the grading credit.
