Diltiazem Pharmacology

Diltiazem is a non-dihydropyridine calcium channel blocker that can be used in atrial fibrillation as well as hypertension.

One big downside to diltiazem is that it does have a few drug interactions via CYP3A4.

Aripiprazole, apixaban, and certain statins are all examples of medication that can have concentrations increased by adding diltiazem to a patient’s regimen.

Diltiazem works a little differently from dihydropyridine calcium channel blockers (like amlodipine) as it works on the heart AND the vessels.
