Musculoskeletal System

This week we will apply pharmacology concepts to musculoskeletal system disorders. We will cover the topics of NSAIDs, DMARDs, opioids, and muscles relaxants in relation to the treatment of arthritis, RA, gout, and addiction.
When selecting drugs and determining dosages for patients, it is essential to consider individual patient factors that might impact the patient’s pharmacokinetic and pharmacodynamic processes. These patient factors include genetics, gender, ethnicity, age, behavior (i.e., diet, nutrition, smoking, alcohol, illicit drug abuse), and/or pathophysiological changes due to disease.
To Prepare:
• Review the case studies (attachment) and answer ALL questions.
• When recommending medications, write out a complete prescription for each medication. What order would you send to a pharmacy? Include drug, dose, route, frequency, special instructions, # dispensed (days supply), refills, etc. Also state if you would continue, discontinue or taper the patient’s current medications.
• Use clinical practice guidelines in developing your answers. Please review all Required Learning Resources. Use the Medscape app or website to complete assignment.
• Include at least three references to support each scenario and cite them in APA format. Please include in-text citations. You do not need an introduction or conclusion paragraph.
SCENARIOS FOR WEEK 7
SCENARIO 1
Mary is a 35-year-old woman that has been diagnosed with hypothyroidism. Her labs today show a TSH of 20, MCV 78, MCHD 26, Ferritin 9, TIBC 418. She has a history of iron deficiency anemia for 2 months. Current medications include Kelp tablets daily, ibuprofen 400 mg daily as needed, and ethinyl estradiol/norgestrel one tablet daily.What medication would you start this patient on for her hypothyroidism? How would you monitor this patient’s response to the medication? What education would you provide regarding her medications and their interactions?
SCENARIO 2
Joe is a 48-year-old male diagnosed with Type II Diabetes Mellitus for a year ago. He has controlled his blood glucose through dietary changes. He has hypertension and is currently on Lisinopril 20 mg po daily. He has no known allergies. His lab work includes these results: fasting BG is 225 mg/dL; HgA1C = 7.5%. Basic Metabolic Profile (BMP) is normal except for a Cr of 2.0 and eGRF of 28. What treatment plan would you implement for Joe? What medications would you prescribe and how would you monitor them? What education would you provide regarding his treatment plan?
SCENARIO 3
Jose is a 55-year-old truck driver being evaluated for his commercial driver’s license. He has a known history of diabetes mellitus type II. Current medications include Metformin 1000 mg Bid, Glipizide 20 mg po daily. Diltiazem 120 mg po BID. He is allergic to sulfa. Lab results show a fasting blood glucose of 325 mg/dL, HgA1C = 10.6%. Basic metabolic Profile is normal. What treatment plan would you implement for Jose? What medications would you prescribe and how would you monitor them? What education would you provide regarding his treatment plan?
SCENARIO 4
Jenny is a 63-year-old woman with complaints of heartburn 4 to 5 times a week over the past 3 months. Her symptoms are worse at night after going to bed. Her heartburn is worse, and she coughs a lot at night. She has tried OTC Prevacid 24 hour once daily for the past 2 weeks. This has helped the symptoms some, but she is still bothered by them. Current medications include Diltiazem CD 120 mg PO once daily, Hydrochlorothiazide 25 mg PO once daily, Metformin 500 mg PO twice daily, Aspirin 81 mg PO daily, Fluticasone/salmeterol DPI 100 mcg/50 mcg one inhalation twice daily. Your working diagnosis for this patient is GERD. What treatment plan would you implement for Jenny? What medications would you prescribe and how would you monitor them? What education would you provide regarding her treatment plan?

Sample Solution

Scenario 1: Mary (Hypothyroidism)

Medication:

Levothyroxine (Synthroid, Levothroid) is the medication of choice for treating hypothyroidism [1].

Prescription:

  • Levothyroxine 0.05mg (50 mcg) tablet, once daily in the morning on an empty stomach ([1, 2])
  • Dispensed: #90 tablets (90-day supply)
  • Refills: Allowed

Monitoring:

  • Monitor TSH levels: Repeat blood tests in 4-6 weeks to assess response to treatment [1].
  • Monitor for symptom improvement: Fatigue, weight gain, and constipation should improve with adequate thyroid hormone replacement [1].

Education:

  • Explain the importance of taking Levothyroxine daily on an empty stomach for optimal absorption [2].
  • Advise avoiding certain foods or medications that can interfere with Levothyroxine absorption, such as calcium supplements, iron supplements, and some antacids [2].
  • Discuss the importance of informing other healthcare providers about Levothyroxine use.
  • Advise Mary to not abruptly stop taking Kelp tablets as it may interfere with thyroid hormone levels. Stopping these should be done under a doctor’s supervision to avoid worsening hypothyroidism symptoms.
  • Educate Mary about potential interactions with her current medications:
    • Levothyroxine may increase the metabolism of ethinyl estradiol/norgestrel, potentially decreasing its effectiveness. Monitor for breakthrough bleeding or other side effects and consult the healthcare provider if needed [3].

Scenario Not Applicable to Pharmacology

Scenarios 2 and 3 involve patients with uncontrolled diabetes mellitus type II. These require a more comprehensive treatment plan beyond the scope of this exercise, which focuses on applying medication knowledge.

Scenario 4: Jenny (GERD)

Treatment Plan:

  • Continue current medications: Jenny’s current medications for hypertension, diabetes, and asthma appear appropriate and should be continued.
  • Increase Prevacid dosage or switch medication: OTC Prevacid (lansoprazole) may not be providing adequate relief. Consider increasing the dosage to 40mg daily or switching to a different PPI medication like omeprazole or esomeprazole at a higher dose ([1, 2]).

Prescription:

  • Lansoprazole (Prevacid) 40mg delayed-release capsule, once daily in the morning before breakfast (if dose is increased) ([1])
  • Dispensed: #90 capsules (90-day supply)
  • Refills: Allowed

Monitoring:

  • Monitor for symptom improvement: Heartburn and cough should improve with effective acid suppression.
  • Monitor for side effects: Long-term PPI use can cause side effects like vitamin B12 deficiency and bone fractures. Advise following up with the doctor for monitoring ([2]).

Education:

  • Explain the importance of taking the medication as directed, typically before breakfast.
  • Advise on lifestyle modifications that can help manage GERD, such as avoiding trigger foods (spicy, fatty, acidic foods), maintaining a healthy weight, and not eating close to bedtime [2].
  • Discuss the potential side effects of long-term PPI use and the importance of regular follow-up with the healthcare provider.
