Background:
Puerarin is an effective ingredient isolated from Radix Puerariae, a leguminous plant. In China, a large number of early studies suggest that puerarin may be used in the treatment of coronary heart disease. In recent years, puerarin injection has been widely used to treat coronary heart disease and angina pectoris.
Objective:
To systematically evaluate the clinical efficacy and safety of puerarin injection in the treatment of unstable angina pectoris (UAP).
Methods:
Data were retrieved from digital databases, including PubMed, Excerpt Medica Database (EMBASE), China Biology Medicine (CBM), the Cochrane Library, and Chinese databases.
Results:
Compared with patients who were treated with conventional Western medicines alone, the patients who were treated with conventional Western medicines in combination with puerarin injection exhibited significant improvements in the incidence of angina pectoris, electrocardiogram findings, nitroglycerin consumption and plasma endothelin levels.
Conclusions:
Strong evidence suggests that, the use of puerarin in combination with conventional Western medicines is a better treatment option for treating UAP, compared with the use of conventional Western medicines alone.

These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
01:16Antianginal Drugs: Nitrates and β-Blockers
Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
