🇮🇳 nerwita-pg tablet के बारे में (Hindi Summary)
उपयोग: यह दवा न्यूरोपैथिक दर्द (नसों से जुड़ा दर्द) के इलाज के लिए इस्तेमाल की जाती है। इसमें प्रेगाबालिन और नॉर्ट्रिप्टिलीन दो सक्रिय तत्व होते हैं जो नसों के अति सक्रिय संकेतों को शांत करते हैं और दर्द को कम करने में मदद करते हैं। यह मधुमेह से होने वाले नसों के दर्द, दाद के बाद होने वाले दर्द, और रीढ़ की हड्डी की चोट के बाद होने वाले दर्द में प्रभावी है। यह दवा केवल डॉक्टर के पर्चे पर मिलती है और इसे डॉक्टर के बताए अनुसार ही लेना चाहिए।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में नींद आना, चक्कर आना, मुँह सूखना, धुंधली दृष्टि, वजन बढ़ना और हाथ-पैरों में सूजन शामिल हैं। ये आमतौर पर हल्के होते हैं और कुछ समय में ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अगर आपको एलर्जी, आत्महत्या के विचार, या दिल की धड़कन में गड़बड़ी महसूस हो तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। इसे अचानक बंद न करें। जब तक आपको इसका असर पता न चले, वाहन न चलाएं और मशीनरी न चलाएं। शराब का सेवन न करें। अगर आप गर्भवती हैं या स्तनपान करा रही हैं तो डॉक्टर को बताएं। दवा को ठंडी और सूखी जगह पर रखें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Pregabalin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the nervous system, which reduces the release of excitatory neurotransmitters such as glutamate, noradrenaline, and substance P. This leads to decreased nerve excitability and pain signalling. Nortriptyline, a tricyclic antidepressant, inhibits the reuptake of serotonin and noradrenaline in the brain and spinal cord, which enhances descending pain inhibition and helps modulate the perception of pain. Additionally, Nortriptyline has anticholinergic and sedative effects that can help with sleep and anxiety often associated with chronic pain.

Dosage Information
| Adult Dosage | The usual starting dose of this medicine is one tablet taken orally once daily, preferably at bedtime to minimize daytime drowsiness. The dose may be gradually increased by your doctor based on your response and tolerability. The maximum recommended dose is generally one tablet twice daily, but this must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and other medications. Do not adjust the dose without medical advice. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician. |
| Elderly Dosage | Elderly patients (above 65 years) are more sensitive to the effects of this medicine, especially drowsiness, dizziness, and anticholinergic effects. Start with a lower dose and titrate slowly. Renal function should be assessed before initiating therapy, and dose adjustments may be necessary. |
| Renal Impairment | Pregabalin requires dose reduction in renal impairment. For creatinine clearance 30-60 mL/min, the dose should be reduced; for 15-30 mL/min, further reduction; and for <15 mL/min, use is not recommended. Nortriptyline does not require renal dose adjustment, but its anticholinergic effects may worsen urinary retention. Consult your doctor for personalized dosing. |
| Hepatic Impairment | Nortriptyline should be used with caution in patients with hepatic impairment due to reduced metabolism. Pregabalin does not require hepatic dose adjustment. Monitor liver function and adjust dose as needed under medical supervision. |
| Maximum Daily Dose | The maximum daily dose is generally two tablets per day, but this must be determined by a qualified clinician based on individual factors. Do not exceed the prescribed dose. |
