🇮🇳 bronkolast l tablet के बारे में (Hindi Summary)
उपयोग: यह दवा लेवोसेटिरिज़िन और मॉन्टेलुकास्ट का संयोजन है, जिसका उपयोग एलर्जी राइनाइटिस (नाक की एलर्जी) और अस्थमा के इलाज के लिए किया जाता है। यह छींक, बहती नाक, खुजली वाली आंखें, और सांस लेने में कठिनाई जैसे लक्षणों से राहत देती है। यह दवा एलर्जी और अस्थमा दोनों के लक्षणों को नियंत्रित करने में मदद करती है। इसे डॉक्टर के परामर्श के बिना नहीं लेना चाहिए।
साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में सिरदर्द, नींद आना, मुंह सूखना, गले में खराश और पेट दर्द शामिल हैं। ये आमतौर पर हल्के होते हैं और कुछ समय में ठीक हो जाते हैं। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन यदि आपको त्वचा पर चकत्ते, सूजन, या सांस लेने में कठिनाई हो, तो तुरंत डॉक्टर से संपर्क करें।
सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। इससे नींद आ सकती है, इसलिए वाहन चलाने या मशीनरी चलाने से बचें जब तक आपको इसका असर पता न चल जाए। शराब का सेवन न करें क्योंकि इससे नींद और चक्कर बढ़ सकते हैं। यदि आप गर्भवती हैं, स्तनपान करा रही हैं, या आपको किडनी या लीवर की समस्या है, तो अपने डॉक्टर को बताएं। इस दवा को बच्चों की पहुंच से दूर रखें।

🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Levocetirizine is a selective histamine H1-receptor antagonist that blocks histamine from binding to its receptors, reducing allergic symptoms such as sneezing, itching, and runny nose. Montelukast is a leukotriene receptor antagonist that blocks cysteinyl leukotrienes (LTC4, LTD4, LTE4) from binding to CysLT1 receptors in the airways, reducing bronchoconstriction, mucus secretion, and airway inflammation. Together, they address both immediate and delayed allergic responses.

Dosage Information
| Adult Dosage | The usual adult dose of this medicine is one tablet taken orally once daily, preferably in the evening. However, the dose and frequency must be individualized by a qualified clinician based on the indication, age, weight, renal and hepatic function, and response to treatment. Do not self-adjust the dose. Take this medicine exactly as prescribed by your doctor. |
| Pediatric Dosage | Pediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children. |
| Elderly Dosage | Elderly patients may be more sensitive to the side effects of this medicine, especially drowsiness. Dose adjustment may be needed based on kidney and liver function. Consult your doctor for appropriate dosing. |
| Renal Impairment | Dose adjustment is required in patients with kidney problems. Levocetirizine is excreted by the kidneys, and its clearance is reduced in renal impairment. Consult your doctor for appropriate dosing. |
| Hepatic Impairment | Dose adjustment may be needed in patients with liver problems. Montelukast is metabolized in the liver. Consult your doctor for appropriate dosing. |
| Maximum Daily Dose | The maximum recommended daily dose is one tablet (Levocetirizine 4 mg + Montelukast 2.5 mg) once daily. Do not exceed the prescribed dose. |
