Thank you for your question. Enalapril is an angiotensin converting enzyme inhibitor (ACE inhibitor) class of antihypertensive medication. The time it takes for enalapril to have therapeutic effect in lowering blood pressure, depends on your blood pressure, if you have any other medical conditions, if you have a history o renal disease, and your body's ability to absorb the medication.
In general, enalapril is quite fast acting with lowering blood pressure within 12 hours of taking the medication. In some patients, it can take up to two weeks to effectively work. If your blood pressure is not therapeutically lowered by two weeks, we recommend that you see your doctor to determine if your medication needs to be adjusted or changed in order to lower your blood pressure.
