🇮🇳 arixtra 2.5mg injection के बारे में (Hindi Summary)
उपयोग: यह दवा फोंडापेरिनक्स 2.5 मिलीग्राम इंजेक्शन के रूप में उपलब्ध है और इसे त्वचा के नीचे (सबक्यूटेनियस) लगाया जाता है। इसका उपयोग मुख्य रूप से बड़ी हड्डी की सर्जरी, जैसे हिप फ्रैक्चर, हिप रिप्लेसमेंट या नी रिप्लेसमेंट के बाद खून के थक्के बनने से रोकने के लिए किया जाता है। यह दवा खून के थक्के बनाने वाले प्रोटीन को रोककर काम करती है, जिससे खून पतला रहता है और थक्का नहीं बनता। यह दवा डॉक्टर की सलाह पर ही दी जाती है और इसे प्रशिक्षित स्वास्थ्यकर्मी द्वारा ही लगाया जाना चाहिए।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में इंजेक्शन लगाने की जगह पर खून आना, चोट लगना, खून की कमी (एनीमिया), जी मिचलाना और उल्टी शामिल हैं। कुछ मामलों में गंभीर खून बहना, जैसे दिमाग में या पेट में खून आना, हो सकता है। अगर आपको असामान्य खून बहना, काला मल, खून की उल्टी, या तेज सिरदर्द हो, तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: यह दवा केवल डॉक्टर की सलाह पर ही लगवाएं। इसे स्वयं न लगाएं जब तक कि आपको प्रशिक्षण न मिला हो। अपने डॉक्टर को अपनी सभी दवाओं के बारे में बताएं, खासकर खून पतला करने वाली दवाएं, दर्द निवारक दवाएं और एस्पिरिन। चोट लगने से बचें और खून बहने के लक्षणों पर नजर रखें। गुर्दे या लीवर की बीमारी हो तो डॉक्टर को जरूर बताएं। दवा की खुराक खुद से न बदलें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by selectively binding to antithrombin III, a natural protein in the blood that inhibits clotting factors. This binding greatly enhances antithrombin's ability to inactivate factor Xa. Factor Xa is a crucial enzyme in the coagulation cascade that converts prothrombin to thrombin. By inhibiting factor Xa, this medicine reduces thrombin generation, which in turn decreases fibrin formation and clot development. Unlike heparin, this medicine does not directly inhibit thrombin and does not require the presence of the heparin cofactor II. Its action is mediated entirely through antithrombin III.

Strength: 2.5 mg/0.5 mL single-dose prefilled syringe for subcutaneous injection
Dosage Information
| Adult Dosage | The usual adult dose of this medicine for prevention of venous thromboembolism after major orthopedic surgery is 2.5 mg given subcutaneously once daily. For treatment of deep vein thrombosis or pulmonary embolism, the dose may be higher (e.g., 5 mg, 7.5 mg, or 10 mg based on body weight) and is individualized by a qualified clinician. The dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-administer unless trained. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients may have reduced renal function and an increased risk of bleeding. The dose should be selected with caution, and renal function should be monitored. No specific dose adjustment is recommended solely based on age, but individualization is necessary. |
| Renal Impairment | In patients with creatinine clearance between 30 and 50 mL/min, the dose may need to be reduced or used with caution. This medicine is contraindicated in patients with creatinine clearance less than 30 mL/min. Dose must be individualized by a qualified clinician based on renal function. |
| Hepatic Impairment | No specific dose adjustment is recommended for patients with mild to moderate hepatic impairment. However, this medicine should be used with caution in patients with severe hepatic impairment due to an increased risk of bleeding. Dose must be individualized by a qualified clinician. |
| Maximum Daily Dose | The maximum recommended daily dose for the 2.5 mg strength is 2.5 mg once daily for prophylaxis. For treatment doses, the maximum is 10 mg once daily, but this must be determined by a clinician based on indication and patient factors. |
