🇮🇳 olotop eye drop के बारे में (Hindi Summary)

उपयोग: यह दवा एलर्जिक कंजंक्टिवाइटिस (आंखों की एलर्जी) के इलाज के लिए आंखों में डालने वाली दवा है। यह आंखों में खुजली, लालिमा, सूजन और पानी आने जैसे लक्षणों को कम करती है। यह एंटीहिस्टामिन और मास्ट सेल स्टेबलाइज़र के रूप में काम करती है।

साइड इफेक्ट्स: आम दुष्प्रभावों में आंखों में जलन, चुभन, धुंधली दृष्टि, सिरदर्द और मुंह में कड़वा स्वाद शामिल हैं। ये आमतौर पर हल्के होते हैं और अपने आप ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन यदि आपको गंभीर एलर्जी, आंखों में तेज दर्द या दृष्टि में बदलाव हो तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा का उपयोग करने से पहले अपने डॉक्टर को गर्भावस्था, स्तनपान या किसी अन्य आंख की समस्या के बारे में बताएं। ड्रॉपर की नोक को किसी सतह से न छुएं। कॉन्टैक्ट लेंस पहनने से पहले दवा डालें और 10 मिनट बाद ही लेंस पहनें। धुंधली दृष्टि होने पर वाहन न चलाएं।

How It Works

Olopatadine is a dual-action antihistamine and mast cell stabilizer. It selectively antagonizes histamine H1 receptors and prevents the release of histamine and other inflammatory mediators from mast cells. This reduces the allergic response in the conjunctiva.

Mechanism Steps

1
Histamine H1 receptor antagonism: Olopatadine binds to H1 receptors on cells in the eye, preventing histamine from triggering allergic symptoms.
2
Mast cell stabilization: It stabilizes mast cells, reducing the release of histamine and other inflammatory substances.
3
Reduction of allergic response: The combined effects lead to decreased itching, redness, and swelling in the eye.
