A patient with coronary artery disease and diabetes is prescribed tadalafil. What is the most appropriate pharmacist response?

Suggest trying yohimbine instead
Advise the patient that vardenafil is better
Refuse to fill the prescription
Inform the patient that tadalafil is contraindicated with nitrates

The correct answer is: Inform the patient that tadalafil is contraindicated with nitrates

In the case of a patient with coronary artery disease and diabetes being prescribed tadalafil, the appropriate response highlights the significant drug interaction between tadalafil and nitrates. Tadalafil is a phosphodiesterase type 5 inhibitor that is commonly used to treat erectile dysfunction, but it can cause vasodilation and potentially result in a dangerous drop in blood pressure when taken concurrently with nitrates. Patients who are on nitrates due to coronary artery disease are at a heightened risk of experiencing adverse effects from this interaction, which could lead to serious complications. Therefore, informing the patient about the contraindication of tadalafil with nitrates is crucial for their safety. This helps the patient make an informed decision about their treatment options and encourages them to discuss any current medications with their healthcare provider. Taking proactive steps to prevent harmful drug interactions is an essential aspect of the pharmacist's role in patient care.
