🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by releasing nitric oxide, which activates guanylate cyclase, leading to increased cyclic guanosine monophosphate (cGMP) levels. This results in relaxation of vascular smooth muscle, causing vasodilation. The dilation of veins reduces preload, while dilation of arteries reduces afterload, decreasing myocardial oxygen demand. Additionally, dilation of coronary arteries improves blood flow to ischemic areas of the heart.
