🇮🇳 Sormo 20mg Tablet के बारे में (Hindi Summary)
उपयोग: यह दवा एंजाइना (सीने में दर्द) को रोकने के लिए इस्तेमाल की जाती है। यह रक्त वाहिकाओं को फैलाकर दिल तक रक्त का प्रवाह बढ़ाती है और दिल पर दबाव कम करती है। यह दवा तीव्र एंजाइना के दौरे के इलाज के लिए नहीं है, बल्कि दौरे पड़ने की आवृत्ति को कम करने के लिए नियमित रूप से ली जाती है।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में सिरदर्द, चक्कर आना, और चेहरे पर गर्मी लगना शामिल हैं। ये आमतौर पर शुरुआत में होते हैं और धीरे-धीरे कम हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अगर आपको बहुत कम रक्तचाप, बेहोशी, या दिल की धड़कन तेज होने का अनुभव हो, तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। दवा की खुराक खुद से न बदलें और न ही बंद करें। शराब का सेवन न करें क्योंकि इससे चक्कर आ सकते हैं। उठते समय धीरे-धीरे उठें। यदि आपको तीव्र एंजाइना का दौरा पड़े तो तुरंत अपनी तेज काम करने वाली दवा लें और डॉक्टर से संपर्क करें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by releasing nitric oxide, which activates an enzyme called guanylate cyclase in smooth muscle cells. This leads to an increase in cyclic guanosine monophosphate (cGMP), which causes relaxation of vascular smooth muscle. The relaxation of veins and arteries reduces the workload on the heart and improves blood flow to the heart muscle, thereby preventing angina.
