🇮🇳 valfect h 80mg/12.5mg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा उच्च रक्तचाप (हाइपरटेंशन) के इलाज के लिए इस्तेमाल की जाती है। इसमें वैल्सार्टन और हाइड्रोक्लोरोथियाजाइड दो सक्रिय तत्व होते हैं जो मिलकर रक्तचाप को कम करने में मदद करते हैं। वैल्सार्टन रक्त वाहिकाओं को आराम देता है और हाइड्रोक्लोरोथियाजाइड शरीर से अतिरिक्त नमक और पानी को बाहर निकालता है। यह दवा आमतौर पर दिन में एक बार मुँह से ली जाती है। इसे डॉक्टर की सलाह के अनुसार ही लें और बिना पूछे बंद न करें।

साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में चक्कर आना, सिरदर्द, थकान और जी मिचलाना शामिल हैं। कुछ लोगों में पेशाब बार-बार आना, प्यास लगना और इलेक्ट्रोलाइट असंतुलन हो सकता है। गंभीर दुष्प्रभाव दुर्लभ हैं लेकिन इनमें तेज ब्लड प्रेशर गिरना, किडनी की समस्या और एलर्जी प्रतिक्रिया शामिल हो सकती है। अगर आपको कोई असामान्य लक्षण दिखे तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। खुराक बदलें या दवा बंद करने से पहले डॉक्टर से सलाह लें। इस दवा से चक्कर आ सकते हैं, इसलिए वाहन चलाने या मशीन चलाने से बचें जब तक आपको पता न चल जाए कि यह आप पर कैसा असर करती है। पर्याप्त पानी पिएं। शराब से बचें क्योंकि इससे चक्कर और ब्लड प्रेशर कम हो सकता है। अगर आप गर्भवती हैं या गर्भधारण की योजना बना रही हैं तो तुरंत डॉक्टर को बताएं। नियमित रूप से किडनी फंक्शन और इलेक्ट्रोलाइट्स की जांच कराएं।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionValsartan is rapidly absorbed after oral administration, with peak plasma concentrations occurring 2-4 hours after ingestion. Hydrochlorothiazide is also rapidly absorbed, with peak levels at about 1-2 hours. Food may slightly reduce the absorption of hydrochlorothiazide but does not significantly affect valsartan.
DistributionValsartan is highly bound to plasma proteins (about 95%), mainly albumin. Hydrochlorothiazide is about 40-70% bound to plasma proteins. Both drugs distribute into extracellular fluid. Valsartan has a volume of distribution of about 17 liters. Hydrochlorothiazide crosses the placental barrier and is distributed into breast milk.
Protein BindingValsartan: approximately 95% bound to serum proteins. Hydrochlorothiazide: approximately 40-70% bound to plasma proteins.
MetabolismValsartan is minimally metabolized, with only about 20% of the dose converted to inactive metabolites. Hydrochlorothiazide is not metabolized and is excreted unchanged in the urine.
Half-LifeValsartan: approximately 6 hours. Hydrochlorothiazide: approximately 6-15 hours.
ExcretionValsartan is excreted primarily in the feces (about 83%) and urine (about 13%). Hydrochlorothiazide is excreted unchanged in the urine (about 95%).
BioavailabilityValsartan: approximately 23-35% (variable). Hydrochlorothiazide: approximately 60-80%.
Onset of ActionAntihypertensive effect begins within 2-4 hours after oral administration, but maximum blood pressure reduction may take 2-4 weeks of regular use.
Peak Plasma TimeValsartan: 2-4 hours. Hydrochlorothiazide: 1-2 hours.
Duration of ActionBlood pressure lowering effect lasts for about 24 hours, allowing once-daily dosing.

How It Works

This medicine combines two antihypertensive agents with complementary mechanisms. Valsartan selectively blocks the angiotensin II type 1 (AT1) receptor, preventing angiotensin II from exerting its vasoconstrictor and aldosterone-secreting effects. This leads to vasodilation, reduced aldosterone release, and decreased sodium and water retention. Hydrochlorothiazide inhibits the reabsorption of sodium and chloride in the distal convoluted tubule of the kidney, increasing excretion of sodium, chloride, and water. This diuretic effect reduces plasma volume and, over time, lowers peripheral vascular resistance. The combination produces a greater reduction in blood pressure than either agent alone.

Mechanism Steps

1
Valsartan blocks AT1 receptors: Valsartan binds to and blocks angiotensin II type 1 receptors in vascular smooth muscle and adrenal glands, preventing angiotensin II from causing vasoconstriction and aldosterone release.
2
Reduced vasoconstriction and aldosterone: Blockade of AT1 receptors leads to relaxation of blood vessels and decreased aldosterone secretion, which reduces sodium and water retention.
3
Hydrochlorothiazide inhibits sodium reabsorption: Hydrochlorothiazide inhibits the sodium-chloride symporter in the distal convoluted tubule, increasing excretion of sodium, chloride, and water.
4
Reduced plasma volume and peripheral resistance: The diuretic effect reduces plasma volume, while the combined actions lower peripheral vascular resistance, resulting in decreased blood pressure.
