Trapidil[edit]
Trapidil is a pharmaceutical drug that functions primarily as a vasodilator and platelet aggregation inhibitor. It is used in the treatment of various cardiovascular conditions, including angina pectoris and peripheral vascular disease.
Mechanism of Action[edit]
Trapidil works by inhibiting the action of platelet-derived growth factor (PDGF), which plays a significant role in the proliferation of smooth muscle cells and the development of atherosclerosis. By blocking PDGF, trapidil helps to prevent the narrowing of blood vessels and improves blood flow.
Additionally, trapidil has been shown to have anti-inflammatory properties and can inhibit the release of histamine and other inflammatory mediators. This contributes to its effectiveness in reducing vascular inflammation and endothelial dysfunction.
Clinical Uses[edit]
Trapidil is primarily used in the management of:
- Angina pectoris: By dilating the coronary arteries, trapidil increases blood flow to the heart muscle, thereby reducing chest pain and improving exercise tolerance.
- Peripheral vascular disease: It helps to improve blood flow in the limbs, reducing symptoms such as pain and cramping.
- Post-angioplasty restenosis: Trapidil is sometimes used to prevent the re-narrowing of arteries following angioplasty procedures.
Side Effects[edit]
Common side effects of trapidil may include:
In rare cases, more severe side effects such as allergic reactions or gastrointestinal bleeding may occur.
Pharmacokinetics[edit]
Trapidil is administered orally and is absorbed through the gastrointestinal tract. It is metabolized in the liver and excreted primarily through the kidneys. The drug has a relatively short half-life, necessitating multiple doses throughout the day to maintain therapeutic levels.
