Enalapril is a medication commonly used to treat high blood pressure and heart failure. It belongs to a class of drugs known as ACE inhibitors, which work by relaxing blood vessels, making it easier for the heart to pump blood. This helps lower blood pressure and reduces the workload on the heart. Patients taking Enalapril may experience side effects such as dizziness, headache, or a persistent cough. It is important to follow a healthcare provider's instructions regarding dosage and to have regular check-ups to monitor blood pressure and kidney function while on this medication.
