Psychopharmacology for Advanced Psychiatric Mental Health Practice prepares PMHNP students to prescribe psychiatric medications safely for acute and chronic conditions across diverse populations.
It sits in term 4 of WGU's MSN - Psychiatric Mental Health Nurse Practitioner program at 3 competency units, building on the general Advanced Pharmacology for the Advanced Practice Nurse course.
The volume of drugs, side effects and interactions is what most students find heavy. The course rewards understanding mechanisms and monitoring principles rather than memorizing lists.

What D345 Covers
WGU describes the course as covering advanced pharmacotherapeutics, experimental versus clinical psychopharmacology, pharmacokinetics and pharmacodynamics, patient education, addiction and substance use (prevalence, presentation and treatment), and collaborative services such as group counseling, therapeutic communities and medication support. The three competencies are:
- Assess a patient's mental health status to prescribe appropriate agents safely.
- Incorporate best practices for patients with signs of substance use or addiction.
- Recommend appropriate, effective medications for mental health conditions and psychiatric disorders.
Key Concepts Explained
Pharmacokinetics and Pharmacodynamics
Pharmacokinetics is what the body does to the drug (absorption, distribution, metabolism, excretion). Pharmacodynamics is what the drug does to the body (receptor effects). Age, liver and kidney function, pregnancy and genetics all alter both.
Example (fictional): A 78-year-old woman with depression has reduced kidney function and takes several other medicines. A medication plan would start at a low dose, increase slowly, choose an agent with fewer anticholinergic and fall-risk effects, check for interactions, and schedule closer follow-up. "Start low, go slow" reflects changed pharmacokinetics in older adults.
Monitoring as Part of Prescribing
Many psychotropics need baseline and follow-up monitoring. Examples include metabolic monitoring with second-generation antipsychotics and blood level and organ function checks with lithium. A plan without monitoring is incomplete.
Substance Use Disorders
The course covers recognizing and treating substance use, including medications for some disorders alongside counseling and community support. Screening, harm reduction and coordinated care matter as much as the prescription.
Typical Assignments and How to Approach Them
| Assignment type | What it tests | How to approach it |
|---|---|---|
| Prescribing case | Safe, justified drug choice | Assess, choose, dose, monitor, educate and follow up |
| Drug class comparison | Mechanisms and side effects | Tabulate mechanism, indications, key risks and monitoring |
| Substance use plan | Best practice for addiction | Combine medication, behavioral treatment and community resources |
| Patient education | Communicating risks and benefits | Use plain language, cover onset time and warning signs |
Prescribing Across the Lifespan
WGU's description stresses individualized drug management based on setting, context and professional ethics. That means adjusting choices for children and adolescents, pregnancy and breastfeeding, older adults and patients with medical comorbidity.
In written work, show that you considered the population: cite guidance on safety warnings where relevant, explain why a dose or agent was adjusted, and include shared decision-making with the patient or family. Current drug references and clinical guidelines should support every recommendation.
Major Drug Classes at a Glance
A compact overview helps you organize the large volume of material. Use it as a starting point and confirm details in current drug references and guidelines.
| Class | Common uses | Key cautions and monitoring |
|---|---|---|
| SSRIs and SNRIs | Depression, anxiety disorders | Activation, sexual effects, serotonin syndrome risk, suicidality warnings in young people |
| Second-generation antipsychotics | Psychosis, bipolar disorder, some adjunctive uses | Weight, glucose and lipid monitoring; movement effects |
| Lithium | Bipolar disorder | Narrow therapeutic range; blood levels, kidney and thyroid checks |
| Anticonvulsant mood stabilizers | Bipolar disorder | Agent-specific risks, including teratogenicity and blood monitoring |
| Benzodiazepines | Short-term anxiety, alcohol withdrawal | Dependence, sedation, falls, respiratory risk with opioids |
| Stimulants | ADHD | Blood pressure, heart rate, appetite, misuse potential |
For each class, learn the mechanism first. Side effects usually follow logically from which receptors the drug affects.
Where Students Get Stuck
- Memorizing without mechanisms. Understanding receptor action explains both benefits and side effects.
- Forgetting monitoring and follow-up. Rubrics often expect both.
- Outdated sources. Use current guidelines and drug references.
- Ignoring substance use. Screen for it in every case; it changes diagnosis and drug choice.
Study Tips for D345
- Build one table per drug class: mechanism, uses, key adverse effects, interactions, monitoring.
- Review receptor basics (serotonin, dopamine, norepinephrine, GABA, glutamate) first.
- Practice full prescribing cases rather than isolated drug facts.
- Write a short patient teaching script for each major class.
