🇮🇳 etotan-h 25mg/12.5mg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा उच्च रक्तचाप (हाई ब्लड प्रेशर) के इलाज के लिए इस्तेमाल की जाती है। इसमें लोसार्टन और हाइड्रोक्लोरोथियाजाइड दो सक्रिय तत्व हैं, जो मिलकर रक्त वाहिकाओं को आराम देते हैं और शरीर से अतिरिक्त नमक और पानी को बाहर निकालते हैं। यह दवा आमतौर पर दिन में एक बार मुँह से ली जाती है। यह डॉक्टर के पर्चे के बिना नहीं लेनी चाहिए।

साइड इफेक्ट्स: इस दवा के आम दुष्प्रभावों में चक्कर आना, सिरदर्द, थकान, और पेशाब में वृद्धि शामिल हैं। कुछ लोगों को मांसपेशियों में ऐंठन या जी मिचलाना भी हो सकता है। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अगर चेहरे, होंठ या गले में सूजन, सांस लेने में कठिनाई, या गंभीर त्वचा पर लाल चकत्ते दिखें तो तुरंत डॉक्टर से मिलें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। इसे अचानक बंद न करें, क्योंकि इससे रक्तचाप फिर से बढ़ सकता है। पर्याप्त पानी पिएं और शराब से बचें। नियमित रूप से रक्तचाप, गुर्दे की कार्यप्रणाली और इलेक्ट्रोलाइट स्तर की जाँच कराते रहें। अगर आप गर्भवती हैं या स्तनपान करा रही हैं, तो डॉक्टर को बताएं।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLosartan is well absorbed after oral administration, but it undergoes some first-pass metabolism. Hydrochlorothiazide is also absorbed from the gastrointestinal tract, though its absorption may be reduced when taken with food. Exact absorption percentages are not established from the available information for this specific combination.
DistributionLosartan and its active metabolite are highly bound to plasma proteins and distribute into body tissues. Hydrochlorothiazide distributes into extracellular fluid and does not significantly accumulate in tissues. Specific volume of distribution values are not established from the available information for this combination.
Protein BindingLosartan is about 98% bound to plasma proteins. Hydrochlorothiazide is about 40-68% bound to plasma proteins. These values are for the individual components.
MetabolismLosartan is metabolized in the liver to an active metabolite, E-3174, which is more potent than losartan itself. Hydrochlorothiazide is not metabolized and is excreted unchanged by the kidneys.
Half-LifeThe elimination half-life of losartan is about 2 hours, and its active metabolite is about 6-9 hours. Hydrochlorothiazide has a half-life of about 6-15 hours. These values are for the individual components.
ExcretionLosartan and its metabolites are excreted mainly in urine and bile. Hydrochlorothiazide is excreted unchanged in urine. Specific percentages are not established from the available information for this combination.
BioavailabilityThe bioavailability of losartan is about 33%, and that of hydrochlorothiazide is about 65-70%. These values are for the individual components and may vary.
Onset of ActionBlood pressure lowering effect may begin within a few hours after the first dose, but the full effect may take 2-4 weeks of regular use.
Peak Plasma TimeLosartan reaches peak plasma levels in about 1 hour, and its active metabolite in about 3-4 hours. Hydrochlorothiazide peaks in about 1-2 hours. These values are for the individual components.
Duration of ActionThe blood pressure lowering effect lasts for about 24 hours, allowing once-daily dosing.

How It Works

This medicine combines two active ingredients with different but complementary ways of lowering blood pressure. Losartan blocks angiotensin II receptors, which prevents a powerful blood vessel-narrowing hormone from doing its work, so blood vessels relax and blood pressure falls. Hydrochlorothiazide increases the removal of sodium and water through the kidneys, which reduces blood volume and also helps blood vessels relax over time. The result is a more effective blood pressure reduction than either ingredient alone.

Mechanism Steps

1
Losartan blocks AT1 receptors: Losartan binds to angiotensin II receptor type 1, preventing angiotensin II from causing blood vessels to narrow.
2
Blood vessels relax: With the receptor blocked, blood vessels widen, which lowers blood pressure and reduces the heart's workload.
3
Hydrochlorothiazide inhibits sodium reabsorption: Hydrochlorothiazide blocks the sodium-chloride symporter in the kidney's distal tubule, so more sodium and water are excreted in urine.
4
Fluid volume decreases: The increased urine output reduces blood volume, which further lowers blood pressure.
5
Combined effect: The two mechanisms work together to produce a greater blood pressure reduction than either ingredient alone.
