Especially for patients with unstable angina pectoris, chest tightness, shortness of breath, palpitation, precordial discomfort and pain in the precordial area, the application of quick-acting Heart Relief Pill can play a role in relieving coronary artery ischemia, stenosis and spasm, and the compound Dan Shen Drops can also play a role in activating blood circulation and resolving blood stasis, improving myocardial cell hypoxia and insufficient blood supply. Therefore, the two drugs can be taken at the same time, but the mechanism of action is different, so it is recommended to take them after an interval of 5-10 minutes. If the patient’s symptoms are not relieved, it is recommended to go to the hospital quickly for the next step of treatment.
