FAFP1 Pharmaceutical care I 2019 – 2020, 1st seminar Classification of DRPs according to PCNE V8.02 – case studies PharmDr. Bc. Dana Mazankova, Ph.D.
Classification of Drug related problems - PCNE Classification V 8.02
Case 1: Mrs. Terning
You are the pharmacist and Mrs. Terning comes in to ask you to recommend an OTC sleep aid (some OTC
drug). In your conversation with her, you learn her husband has recently passed away and she is not feel
well. You believe she is probably depressed from this situation and you should probably call her physician
(arrange her a visit).
Case 2: Mr. Howard
You accidentally fill an Rx for penicillin for Mr. Howard who is allergic to penicillin. Before you can call him
he takes the penicillin. He claims he’s fine when you reach him by phone that evening. When you reach his
home his neighbor tells you Mr. Howard is in the emergency room in hospital.
Case 3: amlodipin
A patient presents a new Rx Norvasc 10 mg (amlodipine) for BP of 164/102. He has never had blood pressure
(BP) of 164/102. He has never had this medicine before. You think this is too high a dose (usual initial dose
is 2.5 mg dose per day). How do you re-phrase the sentence “dose is too high” in words that will not offend
the presciber (doctor)?
Case 4: Mrs. Anton
Mrs Anton, an 87 year old lady, has been taking digoxin 0.25 mg daily for her atrial fibrillation for 3 years.
Recently you have noticed that she is getting increasingly frail and may have lost weight. Today morning she
presents a new prescription for digoxin. While you prepare the prescription in pharmacy, she tells you that
she has been having visual disturbance and wonders if she needs her glasses replaced. You recognise the
possible side effect of the digoxin and tell her not to take the digoxin for one day and to go to her GP
tomorrow to explain her symptoms.
