The blood pressure lowering effect of captopril is quite good. Captopril is a classical angiotensin-converting enzyme inhibitor class of antihypertensive drugs, the effect of lowering blood pressure is relatively good, also can improve the cardiovascular system reconstruction, but the half-life of captopril is relatively short, need to take the drug several times in a day. Therefore, for some people with high blood pressure, the effect of lowering blood pressure may be poor because the individual’s body may not be very sensitive to this drug. If Captopril is not effective in treating hypertension alone, it can be combined with one of the calcium channel blockers to lower blood pressure. If the effect is still poor, you can then combine diuretics, beta-blockers, angiotensin II receptor antagonists and other antihypertensive drugs.
