Systolic blood pressure after taking nifedipine controlled-release tablets is 104 mmHg normal, while diastolic blood pressure of 104 mmHg is not normal, so you can’t generalize. Hypertension is diagnosed if the average of three measurements taken on a different day is ≥140/90mmhg. After ineffective treatment through lifestyle intervention, nifedipine controlled-release tablets can be taken as prescribed by the doctor for antihypertensive treatment. If the systolic blood pressure is 104 mmhg after taking the medication, it belongs to the normal blood pressure range and is usually not a cause for concern. If the diastolic blood pressure is 104mmhg after taking the medicine, then it belongs to the range of second-degree hypertension, which may be due to the insufficient strength of the antihypertensive drug or the insensitivity to the antihypertensive drug, and can be replaced by other antihypertensive drugs and combined drugs, such as hydrochlorothiazide, metoprolol, etc., after the doctor’s comprehensive assessment of the condition. Nifedipine controlled-release tablets belong to calcium channel blockers, can reduce the extracellular calcium ions into the vascular smooth muscle cells, reduce the contractile response of resistance vessels, mainly used in the treatment of hypertension and other diseases. However, the drug may cause dizziness, nausea, vomiting and other discomforts after taking it. For cardiogenic shock, unstable angina is prohibited. In the process of taking the drug, it is necessary to pay attention to monitoring blood pressure and liver and kidney functions. Children and elderly patients need to use the drug under the guidance of a doctor. If the diastolic blood pressure is 104mmhg after taking nifedipine controlled-release tablets, it is recommended to go to the hospital in time, and carry out symptomatic treatment under the guidance of doctors.
