🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by releasing nitric oxide, which activates guanylate cyclase and increases cyclic GMP levels in smooth muscle cells. This leads to relaxation of vascular smooth muscle, resulting in vasodilation. The dilation of veins reduces preload, while dilation of arteries reduces afterload, decreasing myocardial oxygen demand. Additionally, it dilates coronary arteries, improving blood flow to the heart muscle.
