Key takeaways
Enalapril (Vasotec, Epaned) and nisoldipine (Sular) are both medications used to treat high blood pressure. However, they belong to different medication classes. Enalapril is an angiotensin-converting enzyme (ACE) inhibitor, while nisoldipine is a calcium channel blocker (CCB). Enalapril is also FDA-approved for treating heart failure, whereas nisoldipine is not. Enalapril can be taken once or twice daily, and it is available in both tablet and liquid forms, making it suitable for children as young as 1 month old. Nisoldipine is taken once daily as an extended-release tablet on an empty stomach. Common side effects of enalapril include tiredness, dizziness, and cough, while nisoldipine may cause swelling in the legs and feet and headaches. Enalapril can interact with nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Motrin, Advil), whereas nisoldipine interacts with grapefruit and several other medications. Both medications require a prescription and are not controlled substances.
