During a drug regimen review, a technician notices that a patient, Tomasz Bellaire, is receiving both lisinopril 20 mg daily and ramipril 5 mg daily from two different prescribers. Both medicines belong to the same therapeutic class. What is the technician's most appropriate first action?
- ADispense both medicines as written, because each was ordered by a separate prescriber with independent authority
- BAlert the pharmacist to the duplicate ACE inhibitor therapy so the issue can be assessed and the prescribers contacted Correct
- CSubstitute one of the two medicines for an angiotensin receptor blocker without contacting either prescriber
- DReduce the lisinopril dose by half and dispense the ramipril at the full ordered strength
Why A is wrong: It is tempting because two valid prescriptions exist from two prescribers, but separate authority does not resolve the duplication of two ACE inhibitors, which raises the risk of hypotension and hyperkalaemia and must be flagged before dispensing.
Why B is correct: Lisinopril and ramipril are both ACE inhibitors, so taking both is a therapeutic duplication; the technician's role is to detect the flag and escalate to the pharmacist, who clinically evaluates and intervenes with the prescribers.
Why C is wrong: It seems reasonable because an ARB avoids stacking two ACE inhibitors, but a technician cannot change therapy on their own authority, and switching classes still requires a prescriber decision.
Why D is wrong: It appears to lower the combined effect, but altering a prescribed dose is outside the technician's scope and dose reduction does not address that two same-class agents are still being taken together.
