Frequent Fallacies Identified in a Pharmacology Prescription error Case Study.
A prescription errors pharmacology case study is one of the strengths because it shows the recurring errors identified within the healthcare field.
Wrong Drug Identification.
One of the mistakes that should be avoided is a mix of brand and generic names. The case study of prescription errors pharmacology tends to attract attention to the fact that such errors may include the provision of a completely incorrect medicine.
Inappropriate Dosing
Patients are often harmed due to dose miscalculations, particularly controlled substances. Such mistakes underline the necessity to know the half-life and metabolism along with individual dosing in patients.
Lost or Unfulfilled Orders.
The right prescription should have all the necessary elements. Case study analysis of prescription errors in pharmacology commonly includes the following omissions; route, frequency, or refill limitations.
Omission to examine the History of the Patients.
A significant factor behind prescribing error is disregard of renal, age, comorbid, or co-existing medications, and is frequently taught in case-based pharmacology.
Prescription Errors Pharmacology Case Study, Educational Value.

SAMPLE QUESTION
SCENARIO 1
What are the errors in the following prescriptions (1 per prescription)? Rewrite each prescription correctly. What is each medication classification? What is the mechanism of action (MOA)? Appropriate medication is prescribed or changed. Rationale provided and includes current literature to support decision. All aspects of the patient history are considered in making the medication selection.
- methylphenidate 5 mg po BID before breakfast and lunch #60 1 refill
- zolpidem 10 mg po qhs #30 6 refills
- alprazolam (Valium) 0.5 mg po TID #90 1 refill
- pregabalin 75 mg po BID #60 6 refills
- infliximab (Humira) 40 mg SQ inject every other week #2 1 RF
SCENARIO 2
Nicotine stimulates nicotinic acetylcholine receptors in the brain, leading to increased release of dopamine, norepinephrine, serotonin, acetylcholine, and glutamate. These neurochemical effects can temporarily enhance mood, concentration, and alertness—making nicotine use feel relaxing or mentally focusing. Many individuals with ADHD, anxiety, or depression use tobacco products as a form of self-medication. Identify a single prescription medication that can address depression, ADHD symptoms, and assist with smoking cessation. Write a complete medication order for this drug, and include monitoring and patient counseling. Should the patient quit smoking before beginning the medication?
SCENARIO 3
Tramadol has a half-life of 6 hours. If a patient takes 50 mg at 21:00, what will the blood level be at 09:00 the next morning? Name 3 antidepressants that can be prescribed for pain-related conditions (eg fibromyalgia, neuropathic pain, or chronic musculoskeletal pain). Include complete medication orders, MOA and common side effects for each of the 3 medications.
SCENARIO 4
PL is a 42-year-old female presenting for medication refills. She has no recent lab work, but reports fatigue and occasional dizziness. Current meds: metformin 1000 mg PO daily, Invokamet 50/500 mg BID with meals, eszopiclone 2 mg po qHS, atomoxetine 40 mg po daily, and gabapentin 300 mg PO TID. How would you assess and improve her regimen? What monitoring is needed? List 5 possible disease states based on her medications.

ANSWER
Medication Safety, Pharmacologic Decision-Making and Clinical Optimization: Case-Based Analysis.
Introduction
The history and current evidence-based guidelines need to be used to make a specific clinical decision and prescribe drugs with safe and effective pharmacologic management, which presupposes proper prescription writing, knowledge of drug-classification and their mechanism of action, and individual treatment of patients. Medication errors, which include wrong doses, wrong refills, and misidentification of drugs, may cause undesirable consequences, legal problems, and failure to treat. In this paper, four clinical cases will be investigated with the aim of evaluating errors in prescribing medications, the pharmacologic aspects, the correct choice of drugs, and their optimal use. In both scenarios, the existing clinical literature is incorporated with the rationale based on guidelines to enhance safe prescribing practices.
Scenario 1: Detection and Prevention of Prescription mistakes.
Methylphenidate
Identified Error
The prescription did not specify the formulation of the medication (immediate-release or extended-release) and gave a refill of a Schedule II controlled substance, which is not allowed under the U.S. federal law.
Corrected Prescription
Methylphenidate immediate-release 5 mg tablet.
Use once a tablet orally, 30 minutes prior to breakfast and lunch.
Dispense 60 tablets
No refills
Medication Classification
stimulant of central nervous system.
Mechanism of Action
Methylphenidate suppresses the uptake of dopamine and norepinephrine in the prefrontal cortex which improves attention, impulse control, and executive functioning.
Rationale
The use of immediate-release methylphenidate is suitable in the initial treatment and dose titration of ADHD. To minimize misuse and diversion, Schedule II stimulants need new prescriptions each time (UpToDate, 2024).
Zolpidem
Identified Error
The dose was higher than the maximum dose suggested by the FDA in women and refills were too many in controlled hypnotic.
Corrected Prescription
Zolpidem 5 mg tablet
One tablet orally at night as required to treat insomnia.
Dispense 30 tablets
No refills
Medication Classification
Non-benzodiazepine hypnotic (Z-drug).
Mechanism of Action
Zolpidem is a selective a1 subunit of GABA-A receptor, which induces sedative action.
Rationale
The metabolism of zolpidem is lower in women, which puts them at risk of experiencing psychomotor impairment the following day. The highest dosage of 5 mg per night is advised by the FDA (FDA, 2022).
Alprazolam
Identified Error
The unusual prescription identified the alprazolam as Valium, a brand name of diazepam.
Corrected Prescription
Alprazolam 0.5 mg tablet
Use one tablet orally and in 3 doses per day as needed in the case of anxiety.
Dispense 90 tablets
No refills
Medication Classification
Benzodiazepine
Mechanism of Action
Alprazolam augments inhibitory actions of gamma-aminobutyric acid (GABA) at the GABA-A receptor which results in anxiolytic and sedative actions.
Rationale
The correct identification of drug is of paramount importance to patient safety. Refill reduction minimizes the risks of dependence and withdrawal of benzodiazepines.
Pregabalin
Identified Error
It was over-prescribed with more refills of a controlled substance that is scheduled V.
Corrected Prescription
Pregabalin 75 mg capsule
Once a day orally, twice a day.
Dispense 60 capsules
Two refills
Medication Classification
Neuropathic pain agent; anticonvulsant.
Mechanism of Action
Pregabalin is an antagonist of the a2d subunit of calcium channels, which decreases the release of excitatory neurotransmitters.
Rationale
The refill restrictions encourage regular reevaluation as the use of pregabalin is likely to be abused and has side effects that improve with each dose.
Adalimumab
Identified Error
The prescription had mistakenly made the identical error of comparing infliximab to the Humira, the brand name of adalimumab.
Corrected Prescription
Adalimumab (Humira) 40 mg/ 0.4 mL pre-filled pen.
Administration 40 mg under the skin after every other week.
Dispense two pens
One refill
Medication Classification
Tumor necrosis factor- alpha (TNF-a) inhibitor
Mechanism of Action
TNF-a is inhibited by adalimumab that binds to it.
Rationale
Tuberculosis screening is a required infection risk monitoring with appropriate drug identification in biologic therapies.
Scenario 2: Pharmacologic Management of Depression, ADHD and Smoking Cessation.
Medication Selection
Bupropion sustained-release (SR) is a single-agent treatment that is adequate in treating depression, and ADHD symptoms, and also in smoking cessation.
Complete Medication Order
Bupropion SR 150 mg tablet
Administer one tablet orally after three days and then administer 150 mg twice a day.
Dispense 60 tablets
Two refills
Mechanism of Action
Bupropion is an norepinephrine-dopamine reuptake inhibitor which increases dopaminergic activity in reward systems, decreases nicotine cravings and improves mood and concentration.
Rationale and Counseling
Smoking cessation Bupropion is approved by the FDA and has shown to be effective in adult ADHD. The patients do not have to quit smoking before the initiation, there is usually a quit date, which is one or two weeks after starting the therapy. Monitoring consists of blood pressure, mood variation, insomnia, and risk of seizures.
Scenario 3: Pharmacokinetics and Antidepressants to the Pain.
Calculation of Half-Life of Tramadol.
The half-life of Tramadol is six hours. Twelve hours (two half-lives) later there is still 25 percent of the original dose. Hence, an initial dose of 50 mg at 21:00 would be left the following morning at 09:00 of about 12.5 mg.
Antidepressants in the treatment of pain.
Duloxetine
Duloxetine 30 mg capsule
One capsule should be taken orally every day during a period of seven days after which the dose should be raised to 60 mg/day.
Dispense 30 capsules
Two refills
MOA and Side Effects
Duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI) which increases descending pathways of pain inhibition. The usual side effects are nausea, dry mouth and high blood pressure.
Amitriptyline
Amitriptyline 10 mg tablet
One tablet orally at night.
Dispense 30 tablets
One refill
MOA and Side Effects
Antidepressant that is a tricyclic and prevents the reuptake of serotonin and norepinephrine. Side effects include a general state of sedation, anticholinergics, and QT prolongation.
Venlafaxine Extended-Release
Venlafaxine XR 37.5 mg capsule
administer one capsule orally as intolerable.
Dispense 30 capsules
Two refills
MOA and Side Effects
Venlafaxine improves serotonergic and noradrenergic neurotransmitters. The side effects include nausea, insomnia and hypertension.
Scenario 4: Evaluation and Optimization of the Medication Regimen.
Clinical Assessment
PL is a 42-year-old female who would be reporting with her medication refills, and no recent lab investigation. She also complains of fatigue and dizziness taking various drugs, including metformin therapy twice (metformin and Invokamet).
Recommended Interventions
Stop independent metformin to eliminate duplication of therapy.
Invokamet should be continued with renal monitoring.
Evaluate eszopiclone and gabapentin on adverse effects of sedation.
Assess atomoxetine in orthostatic hypotension.
Monitoring Recommendations
HbA 1C and fasting glucose.
Complete metabolic and estimated glomerular filtration rate.
Vitamin B12 level
Orthostatic vital and blood pressure.
Potential Disease States
Type 2 diabetes mellitus
Attention-deficit/hyperactivity disorder
Insomnia
Neuropathic pain
Fear or major depression.
Conclusion
Such situations underscore the need to accurately write prescriptions, make correct choices in selecting medications, and make clinical decisions that are patient-centered. The combination of the pharmacologic knowledge with the existing clinical guidelines minimizes medication errors, enhances patient outcomes, and provides the opportunity to engage in the safe prescribing practices in the case of a wide range of clinical manifestations.
