The best time to take Betaloc is around 6 o’clock in the morning. Because Betaloc is a beta-blocker, it can effectively inhibit sympathetic excitation, and the highest point of sympathetic excitation is between 8 and 12 am, so taking Betaloc 2 hours before its peak point can effectively inhibit sympathetic excitation, which can effectively lower the heart rate and blood pressure. For patients with coronary artery disease combined with high blood pressure, Betaloc is the best drug of choice because it not only lowers blood pressure, but also reduces heart rate and myocardial oxygen consumption, which can effectively relieve symptoms such as panic, chest tightness, shortness of breath, and dizziness and headache caused by high blood pressure. Betalac is also divided into extended-release tablets and flat tablets. Extended-release tablets are taken once a day, while flat tablets are taken twice a day. Patients are usually advised to take extended-release tablets because they can last for 24 hours and are more stable and effective.
