Unit 2:
A.C. is a 60-year-old Caucasian woman with newly diagnosed peptic ulcer
disease, generalized anxiety disorder, and iron deficiency anemia. She also
has a long history of asthma and depression. She is a strong believer of
herbal medicine. She takes St. John’s wort for her depression, iron pills for
her anemia, and alprazolam (Xanax) as needed for her anxiety. During her
asthma exacerbation, she is instructed to take prednisone for at least 5
days. She also takes esomeprazole (Nexium) for her peptic ulcer disease.
Three months later, she experienced severe fatigue, shortness of breath,
dizziness, and swelling/soreness in the tongue. Her asthma is well
controlled with the occasional use of albuterol (Proventil) inhaler. During
her physical exam, her physician suspected that she had bacterial vaginosis
and gave her a prescription for a 1-week course of metronidazole (Flagyl).
She drinks at least two to three cans of beer per day.
1. St. John’s wort is known to inhibit which of her medication that is known
to be metabolized by cytochrome P-450 (CYP3A4) and could potentially
cause her to experience significant fatigue?
2. Which of her medications could interfere with the absorption of her iron
pills?
3. Which of her medications could potentially cause her to develop vitamin
B12 deficiency?
4. How does metronidazole interfere with alcohol?
5. If she were given a prescription for ketoconazole, which of her
medications could interfere with its absorption?
• As you complete the remainder of your remediation, make note of
specific drug-drug and drug-food interactions as you encounter
them.
• Choose one of the medications in the case study above. Review the
half-life of that medication and describe the concept of half-life
specific to that medication.
Unit 3
,M.W. is a 70-year-old white woman with a medical history of hypertension,
osteoarthritis, atrial fibrillation, and total hysterectomy who lives by herself
in a two-story row home. She visits the primary care clinic with her
daughter, who is concerned because M.W. has “bounced” a few checks and
can no longer pay her bills without assistance. M.W. admits that she has
been forgetful and appears anxious as she describes an incident in which
she went shopping and could not remember where she parked her car. Her
daughter states that her mother’s memory has progressively worsened over
the past year. M.W.’s medications include fosinopril 20 mg PO daily,
metoprolol succinate ER 50 mg PO daily, warfarin 5 mg PO daily, vitamin D
1,000 IU PO daily, and acetaminophen 325 mg 2 tablets (650 mg) PO tid. A
careful evaluation and workup were ordered. Diagnosis: Mild AD with an
MMSE Score of 22
1. List specific goals of treatment for M.W.
2. What drug therapy would you prescribe for M.W.? Why?
3. What are the parameters for monitoring success of therapy?
4. Discuss specific patient education based on prescribed therapy.
5. List one or two adverse reactions for the selected agent that would cause
you to change therapy.
6. What would be the choice for second-line therapy?
7. Would there be any over-the-counter and/or alternative agents
appropriate for M.W.?
8. What lifestyle changes would you recommend to M.W.?
9. Describe one or two drug–drug or drug–food interactions for the selected
agents
M.P. is a 66-year-old man with past medical history of hypertension and
hyperlipidemia presenting to the clinic describing problems with balance
and gait that have worsened in the past few months. A gait assessment
reveals reduced arm swing while walking and a single halt hesitation when
turning. During straight walking, he continues smoothly without freezing.
, The MDS-UPDRS reveals slight impairment related to postural instability
and mild impairment related to both gait and freezing. Based on his history
and physical exam, he is diagnosed with PD. Following his diagnosis, he
mentions that he is considering retirement. Diagnosis: Parkinson Disease
1. Which of the following is not an appropriate goal of therapy for M.P.?
a. Maintain patient independence by alleviating motor symptoms.
b. Preserve patient ability to perform activities of daily living.
c. Reverse disease progression.
d. Maintain patient quality of life by alleviating nonmotor symptoms.
2. What is the most appropriate initial therapy for M.P.?
a. Amantadine 100 mg twice daily
b. Carbidopa/levodopa IR 25 mg/100 mg three times daily
c. Pramipexole IR 0.125 mg three times daily
d. Benztropine 0.5 mg twice daily
3. In addition to the pharmacologic recommendation mentioned above,
which of the recommendations below is most appropriate for M.P.?
a. Referral to a speech therapist
b. High-intensity resistance exercises
c. Qigong
d. Initiation of coenzyme Q10 300 mg daily
J.J., age 24, presents to your practice for the first time. She reports constant
headaches. She smokes a pack of cigarettes a day but is in good health
otherwise. She states that the headaches usually occur in the morning and
last a few hours. The pain, localized to an area near her right temple, has a
throbbing quality. The headache often results in nausea and vomiting and
sensitivity to bright lights. She has tried to treat the headaches with
acetaminophen, ibuprofen, and naproxen unsuccessfully. The headaches are
causing her to miss work, and she is afraid she will lose her job. Diagnosis:
Migraine Headaches without Aura
