Methods
In order to evaluate the blood pressure lowering effects and safety of Intravenous Nicorandil, we recruited 43 inpatients with unstable angina to intravenously pump Nicorandil, and the pumping speeds (2mg/h, 4mg/h and 6mg/h, respectively) were adjusted according to the patient’s blood pressure. After treatment, the effects of Intravenous Nicorandil on blood pressure and drug safety were observed.
