Low blood pressure caused by diltiazem needs to be promptly reduced or discontinued with this medication, and vasoactive drugs such as dopamine may be given to raise blood pressure if necessary.
Diltiazem is a calcium channel blocker. By acting on the calcium channels in the myocardium, coronary blood vessels, smooth muscle of peripheral blood vessels and atrioventricular node, it can relieve and prevent the contraction of myocardial and vascular smooth muscle cells, and it has the effect of dilating coronary arteries and peripheral blood vessels, improving cardiac hypertrophy and prolonging the conduction time of the atrioventricular node, and it can effectively treat hypertension, angina pectoris, and cardiac arrhythmia.
The main adverse reactions that may be caused by taking Diltiazem include swelling, dizziness and headache, nausea, weakness and rash. The rest can also cause a small number of adverse reactions include symptomatic hypotension, atrioventricular block, bradycardia, congestive heart failure, dysgeusia, dyspepsia, dyspnea, hepatic function abnormalities, thrombocytopenia.
In this case, it is necessary to promptly adjust the dose or discontinue the use of this drug. The drug is also contraindicated in patients with sick sinus node syndrome without a pacemaker, atrioventricular block of II or III degree without a pacemaker, systolic blood pressure of less than 90 mmHg, heart rate of less than 50 beats per minute, congestive heart failure, as well as in those who are allergic to the components of the drug.
In case of low blood pressure caused by Diltiazem, the patient should go to the hospital in order to avoid delays in the treatment.
