**Week 9 Assignment: Advanced Pharmacology**

**1. Jamie is a 38-year-old homeless bipolar patient who is diagnosed with an acute psychotic episode. He tells you that he has been on lithium for years and was recently started on imipramine 75 mg daily by someone at a free clinic. What treatment plan would you develop for Jamie? Would you discontinue any medications? What medications would you add?**

**A. Patient History Considered in Making the Medication Selection:**

Jamie’s history includes bipolar disorder and current treatment with lithium. He is experiencing an acute psychotic episode, and recently started on imipramine, which is a tricyclic antidepressant. Given his existing lithium treatment and the new addition of imipramine, it is crucial to review his medication interactions, potential side effects, and overall management of bipolar disorder during acute psychosis.

**B. Medication Prescribed or Changed:**

– **Continue Lithium:** Lithium should be continued at the current dose, considering its efficacy in managing bipolar disorder.
– **Discontinue Imipramine:** Imipramine should be discontinued due to its potential to exacerbate manic symptoms in bipolar disorder and its interaction with lithium.
– **Add Olanzapine (Zyprexa):** Initiate olanzapine 10 mg orally at bedtime for acute psychotic symptoms.

**C. Rationale Provided to Include ‘WHY’ the Decision Using Clinical Guidelines:**

The addition of olanzapine, an atypical antipsychotic, is supported by clinical guidelines for managing acute manic or psychotic episodes in bipolar disorder. Olanzapine is effective for rapid control of acute symptoms. Imipramine, being a tricyclic antidepressant, may induce manic episodes in bipolar disorder, and hence should be discontinued. The combination of lithium and olanzapine aligns with the guidelines for managing acute episodes while minimizing potential interactions and side effects.

**D. Written Medication Orders with All 5 Aspects Required for a Valid Order:**

– **Olanzapine 10 mg orally at bedtime**
– **Dose:** 10 mg
– **Route:** Oral
– **Frequency:** Daily at bedtime
– **Special Instructions:** Take with or without food.
– **# Dispensed:** 30 tablets (30 days supply)
– **Refills:** 1 (Evaluate for efficacy and side effects before additional refills)

**E. References for the Scenario Scholarly, Peer-Reviewed, the Past 5 Years to Include the Appropriate Clinical Practice Guidelines if Applicable:**

**2. A 68-year-old woman has a history of rheumatoid arthritis and has been taking nabumetone (Relafen) 1000 mg po qd for 2 years. Other pertinent past medical history includes occasional incontinence, Crohn’s disease with frequent exacerbations, and well-controlled diabetes type 2. Recently, her arthritis pain has been much worse, and she is requesting additional medication for her rheumatoid arthritis. What would be appropriate additional therapy for this patient? What monitoring would be appropriate to monitor this medication?**

**A. Patient History Considered in Making the Medication Selection:**

The patient has a history of rheumatoid arthritis and is on nabumetone, a nonsteroidal anti-inflammatory drug (NSAID). She also has Crohn’s disease, which necessitates cautious use of additional medications due to potential gastrointestinal issues. Her diabetes and incontinence are well-managed but need to be considered in her overall treatment plan.

**B. Medication Prescribed or Changed:**

– **Add Methotrexate 7.5 mg weekly orally**

**C. Rationale Provided to Include Current Literature to Support the Rationale with Clinical Guidelines:**

Methotrexate is a disease-modifying antirheumatic drug (DMARD) recommended by clinical guidelines for managing moderate to severe rheumatoid arthritis when NSAIDs alone are insufficient. It helps in controlling disease progression and alleviating symptoms. Given her worsening arthritis pain, methotrexate is a suitable addition to her current treatment regimen. Monitoring is necessary due to methotrexate’s potential for gastrointestinal and renal adverse effects.

**D. Written Medication Orders with All 5 Aspects Required for a Valid Order:**

– **Methotrexate 7.5 mg orally once weekly**
– **Dose:** 7.5 mg
– **Route:** Oral
– **Frequency:** Once weekly
– **Special Instructions:** Take with or without food. Monitor for signs of gastrointestinal distress.
– **# Dispensed:** 4 tablets (1-month supply)
– **Refills:** 2 (Evaluate for efficacy and side effects before additional refills)

**3. Sheila is a 26-year-old with a history of head injury and tonic-clonic seizures. She is seen today with complaints of “funny” eye movements, feeling uncoordinated, blurred vision, and feeling lethargic. Her current medications include Ritalin 10 mg po BID, Dilantin 300 mg po BID, Paxil 20 mg po daily, Lasix 20 po daily. Lab Values from today Dilantin level of 11 microg/mL, Albumin 2 g/dL, WBC 9.9 x 10^9/L, Plt 177 x 10^9/L, Na+ 141 mEq/L, K+ 4.2 mEq/L, Hgb 13.2 g/dL. What do you think is causing the patient’s symptoms? What lab values and calculated corrected medication level support your diagnosis? What is your treatment plan for this patient?**

**A. Patient History Considered in Making the Medication Selection:**

Sheila’s symptoms of eye movements, uncoordination, blurred vision, and lethargy suggest a potential issue with her current medications, especially Dilantin (phenytoin), which can cause these side effects. Her lab results indicate low albumin, which can affect the free level of Dilantin.

**B. Medication Prescribed or Changed:**

– **Adjust Dilantin Dose:** Increase Dilantin dosage to 400 mg po BID.
– **Add Albumin Supplement:** Consider adding oral albumin supplementation to improve serum levels.

**C. Rationale Provided to Include Current Literature to Support the Rationale with Clinical Guidelines:**

Dilantin levels can be altered by low serum albumin, leading to increased free drug levels and toxicity. Increasing the dose may be necessary due to the low corrected Dilantin level, though close monitoring is required. The adjustment aims to balance seizure control while minimizing side effects. The addition of albumin supplements helps normalize serum levels to better assess therapeutic efficacy and safety.

**D. Written Medication Orders with All 5 Aspects Required for a Valid Order:**

– **Dilantin 400 mg orally twice daily**
– **Dose:** 400 mg
– **Route:** Oral
– **Frequency:** Twice daily
– **Special Instructions:** Monitor serum levels and signs of toxicity. Take with food if gastrointestinal upset occurs.
– **# Dispensed:** 60 tablets (30 days supply)
– **Refills:** 1 (Evaluate for efficacy and side effects before additional refills)
