🇮🇳 Stemiz 5mg Suspension के बारे में (Hindi Summary)
उपयोग: यह दवा एलर्जी के लक्षणों जैसे छींक, नाक बहना, आंखों में खुजली और त्वचा पर खुजली को कम करने के लिए इस्तेमाल की जाती थी। यह एस्टेमिज़ोल नामक एंटीहिस्टामिन है, जो शरीर में हिस्टामिन के प्रभाव को रोकता है। हालांकि, यह दवा दिल की धड़कन में गंभीर समस्या पैदा कर सकती है, इसलिए अब इसका उपयोग बहुत कम किया जाता है। इसे केवल डॉक्टर की सलाह पर ही लेना चाहिए।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में नींद आना, मुंह सूखना, सिरदर्द, जी मिचलाना और पेट में असहजता शामिल हैं। गंभीर दुष्प्रभावों में दिल की धड़कन अनियमित होना, बेहोशी और गंभीर एलर्जी प्रतिक्रिया शामिल हो सकती है। अगर आपको दिल की धड़कन तेज या अनियमित महसूस हो, चक्कर आएं या बेहोशी हो, तो तुरंत डॉक्टर से मिलें।
सुरक्षा सलाह: यह दवा केवल डॉक्टर की देखरेख में ही लें। निर्धारित मात्रा से अधिक न लें। शराब और नींद लाने वाली दवाओं से बचें। अपने डॉक्टर को अपनी सभी दवाओं के बारे में बताएं। अगर आपको दिल की बीमारी, लीवर की बीमारी या इलेक्ट्रोलाइट असंतुलन है, तो यह दवा न लें। दिल की धड़कन में बदलाव, चक्कर या बेहोशी होने पर तुरंत आपातकालीन चिकित्सा सहायता लें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Astemizole is a second-generation antihistamine that works by selectively blocking histamine H1 receptors. By binding to these receptors, it prevents histamine from triggering allergic symptoms such as sneezing, itching, and vasodilation. Unlike older antihistamines, it was designed to cause less sedation, but it can also block potassium channels in the heart, leading to QT prolongation and serious arrhythmias.
