A patient presents a prescription for Zestril. The technician notes the patient is also taking a potassium supplement. What is the primary safety concern for the pharmacist to review?
Show answer →Safety Concern: Hyperkalemia (high potassium levels). Rational: ACE inhibitors (like lisinopril/Zestril) and ARBs cause the kidneys to retain potassium by inhibiting aldosterone. Combining them with potassium supplements, salt substitutes (which often contain potassium chloride), or potassium-sparing diuretics (like spironolactone) significantly increases the risk of cardiac arrhythmias. Exam Strategy: The PTCB frequently tests electrolyte imbalances and the potassium-sparing nature of RAAS medications.
A patient complains of a dry, hacking cough after starting Altace. Which medication class is most likely to be prescribed as a substitute to avoid this specific side effect?
Show answer →Answer: Angiotensin II Receptor Blockers (ARBs). Rationale: ACE inhibitors (suffix -pril, e.g., ramipril/Altace) prevent the breakdown of bradykinin, leading to its accumulation in the lungs, causing a dry cough in up to 20% of patients. ARBs (suffix -sartan) block the receptor instead of the enzyme and do not affect bradykinin levels. Exam Strategy: If a question mentions bradykinin-induced cough, the most common clinical intervention is switching from an ACEI to an ARB.
Which of the following drug-suffix pairs is correctly matched for the class of medications used to treat hypertension and heart failure by blocking the AT1 receptor?
Show answer →Answer: -sartan (Angiotensin II Receptor Blockers/ARBs). Examples: Losartan (Cozaar), Valsartan (Diovan), Olmesartan (Benicar). Rationale: Unlike ACE inhibitors (-pril), ARBs block the action of Angiotensin II at the receptor site rather than its production. Both classes are first-line for hypertension and provide renal protection. Exam Strategy: Do not confuse -sartan (ARBs) with -statin (HMG-CoA Reductase Inhibitors) or -setron (5-HT3 antagonists).
A female patient of childbearing age is prescribed Cozaar. What critical Black Box Warning must the technician be aware of regarding ACE inhibitors and ARBs?
Show answer →Warning: Fetal Toxicity (Teratogenicity). Rationale: Both ACE inhibitors and ARBs are strictly contraindicated during pregnancy (especially 2nd and 3rd trimesters) because they interfere with the fetal renin-angiotensin system, leading to oligohydramnios, fetal injury, hypotension, and death. Pharmacy technicians should ensure pregnancy-related counseling flags are active for the pharmacist. Exam Strategy: PTCB emphasizes medications with high-risk contraindications for specific populations.
A patient is prescribed Zestoretic. What are the two active components of this combination medication, and what is its primary therapeutic category?
Show answer →Components: Lisinopril and Hydrochlorothiazide (HCTZ). Category: Antihypertensive (ACE Inhibitor + Thiazide Diuretic). Rationale: Combination products improve patient compliance by reducing pill burden. HCTZ helps lower blood pressure via fluid volume reduction, while Lisinopril inhibits the RAAS system. Exam Strategy: Recognize HCT or oretic suffixes in brand names as indicators of hydrochlorothiazide. Common examples include Hyzaar (Losartan/HCTZ) and Benicar HCT (Olmesartan/HCTZ).
