Real Life Pharmacology - Pharmacology Education For Health Care Professionals

On this episode, I discuss verapamil pharmacology, adverse effects, and important drug interactions. There are numerous drug interactions to be aware of with verapamil as it inhibits the enzyme CYP3A4. Verapamil is a calcium channel blocker (non-dihydropyridine) that blocks calcium channels in the heart and vessels. In addition to hypotension and bradycardia, verapamil can cause constipation which may be more prominent in our geriatric patients.
