Abstract:
We investigated whether a single dose of standardized Ginkgo biloba extract (GBE) can improve vascular function. A randomised controlled crossover trial was conducted on 14 young healthy men, who received GBE or placebo. The digital volume pulse was monitored to measure reflection index (DVP-RI) and stiffness index (DVP-SI) and peripheral augmentation index (pAIx) was assessed using radial pulse wave analysis at baseline and 2, 4 and 6 h after treatment. DVP-SI was slightly higher 2 h following GBE compared to placebo (P < 0.05); other outcome variables were unaffected by treatment.

Antianginal 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. Administered...

Treatment for Pulmonary Arterial Hypertension: Phosphodiesterase Inhibitors
Among the PDE5 inhibitors, sildenafil (Revatio) stands out as a competitive and selective inhibitor. It operates by elevating cellular levels of cGMP and augmenting signaling through the cGMP-PKG pathway, promoting vasodilation. Upon oral...
