सुरक्षा सलाह: इस दवा को हमेशा डॉक्टर के बताए अनुसार ही लें। दवा लेते समय बैठें या लेटें, खासकर अगर आपको चक्कर आते हैं। शराब न पिएं क्योंकि इससे ब्लड प्रेशर और कम हो सकता है और बेहोशी आ सकती है। किसी भी सर्जरी या दंत चिकित्सा से पहले अपने डॉक्टर को इस दवा के बारे में बताएं। इरेक्टाइल डिसफंक्शन की दवाओं के साथ इसका सेवन न करें। दवा को ठंडी, सूखी जगह पर, धूप से दूर, बच्चों की पहुंच से बाहर रखें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by releasing nitric oxide, which activates an enzyme called guanylate cyclase inside smooth muscle cells. This leads to an increase in cyclic guanosine monophosphate, which causes the smooth muscle in blood vessels to relax. The result is dilation of veins and arteries, especially veins, which reduces the amount of blood returning to the heart. This lowers the pressure inside the heart chambers and reduces the heart's workload, which in turn decreases the heart's demand for oxygen. At the same time, the widening of coronary arteries can improve blood flow to areas of the heart that are not getting enough oxygen. Together, these effects help prevent angina attacks.
