🇮🇳 dentonex m gel के बारे में (Hindi Summary)
उपयोग: यह दवा मसूड़ों के संक्रमण और सूजन के इलाज के लिए इस्तेमाल की जाने वाली डेंटल जेल है। इसमें क्लोरहेक्सिडिन ग्लूकोनेट और मेट्रोनिडाजोल दो सक्रिय तत्व हैं जो बैक्टीरिया को मारते हैं और मसूड़ों की सूजन कम करते हैं। इसका उपयोग जिंजिवाइटिस, पीरियोडोंटाइटिस और दांत निकालने के बाद के संक्रमण में किया जाता है। इसे डॉक्टर या दंत चिकित्सक के निर्देशानुसार प्रभावित मसूड़ों पर लगाएं। इसे निगलना नहीं चाहिए।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में मसूड़ों में जलन, स्वाद में बदलाव, दांतों या जीभ पर हल्का दाग और मुंह सूखना शामिल हैं। ये आमतौर पर हल्के होते हैं और दवा बंद करने पर ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अगर चेहरे, होंठ या गले में सूजन, सांस लेने में कठिनाई या त्वचा पर चकत्ते दिखें तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को केवल प्रभावित मसूड़ों पर ही लगाएं। इसे निगलें नहीं, लगाने के बाद थूक दें। लगाने के 30 मिनट तक कुछ खाएं या पिएं नहीं। डॉक्टर की सलाह के बिना लंबे समय तक इसका इस्तेमाल न करें। बच्चों की पहुंच से दूर रखें। गर्भवती या स्तनपान कराने वाली महिलाएं डॉक्टर से सलाह लें। अगर आपको किसी भी प्रकार की एलर्जी है या आप अन्य दवाएं ले रहे हैं तो अपने डॉक्टर को बताएं।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two antimicrobial agents with complementary mechanisms. Chlorhexidine gluconate is a bisbiguanide antiseptic that binds to negatively charged bacterial cell walls, disrupting membrane integrity and causing leakage of intracellular contents, leading to bacterial cell death. Metronidazole is a nitroimidazole antibiotic that enters anaerobic bacteria and is reduced by ferredoxin-like electron transport proteins, forming reactive intermediates that damage DNA and inhibit nucleic acid synthesis, resulting in bacterial death. Together, they target a broad range of oral pathogens, including those associated with periodontal disease.
