🇮🇳 aldostix 20 mg/50 mg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा फ्यूरोसेमाइड और स्पाइरोनोलैक्टोन का संयोजन है, जिसका उपयोग शरीर में जमा अतिरिक्त पानी (सूजन) को कम करने के लिए किया जाता है। यह हृदय विफलता, लिवर सिरोसिस और किडनी रोग से जुड़ी सूजन के इलाज में मदद करती है। यह पेशाब की मात्रा बढ़ाती है और पोटैशियम के स्तर को संतुलित रखने में मदद करती है।

साइड इफेक्ट्स: आम दुष्प्रभावों में बार-बार पेशाब आना, चक्कर आना, सिरदर्द, जी मिचलाना और मांसपेशियों में ऐंठन शामिल हैं। गंभीर दुष्प्रभावों में गंभीर निर्जलीकरण, इलेक्ट्रोलाइट असंतुलन, किडनी की समस्या और एलर्जी प्रतिक्रियाएं शामिल हो सकती हैं। यदि आपको लगातार उल्टी, दस्त, असामान्य थकान या संक्रमण के लक्षण दिखें तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। अपनी मर्जी से खुराक न बदलें और न ही दवा बंद करें। पर्याप्त पानी पिएं जब तक डॉक्टर ने तरल पदार्थ प्रतिबंधित न किया हो। शराब से बचें क्योंकि इससे चक्कर और निम्न रक्तचाप बढ़ सकता है। अचानक उठने से बचें। अपने डॉक्टर को अन्य सभी दवाओं के बारे में बताएं। नियमित रक्त परीक्षण कराएं। गर्भावस्था या स्तनपान के दौरान डॉक्टर से सलाह लें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionFurosemide is absorbed from the gastrointestinal tract, with bioavailability varying between 10-100% depending on formulation. Spironolactone is well absorbed from the gastrointestinal tract. Food may affect the absorption of both components.
DistributionFurosemide is highly bound to plasma proteins and distributes into extracellular fluid. Spironolactone and its active metabolites are also highly protein-bound and distribute widely in tissues.
Protein BindingFurosemide is approximately 95% bound to plasma proteins. Spironolactone and its metabolites are more than 90% bound to plasma proteins.
MetabolismFurosemide is partially metabolized in the liver, mainly by glucuronidation. Spironolactone is extensively metabolized in the liver to active metabolites, including canrenone and 7-alpha-thiomethylspirolactone.
Half-LifeThe elimination half-life of furosemide is approximately 0.5 to 2 hours. Spironolactone has a variable half-life, with parent drug around 1.4 hours, but active metabolites have longer half-lives up to 16 hours.
ExcretionFurosemide is excreted primarily in the urine as unchanged drug and metabolites. Spironolactone and its metabolites are excreted mainly in urine and bile.
BioavailabilityFurosemide oral bioavailability is approximately 50-60% but can range from 10-100%. Spironolactone bioavailability is about 90%.
Onset of ActionFurosemide onset of action is within 30-60 minutes after oral administration. Spironolactone onset is slower, typically 1-2 days for full effect.
Peak Plasma TimeFurosemide peak plasma concentration occurs 1-2 hours after oral administration. Spironolactone peak levels are reached in 2-4 hours.
Duration of ActionFurosemide duration of diuretic action is about 4-6 hours. Spironolactone duration is longer, up to 24-48 hours due to active metabolites.

How It Works

This medicine combines two diuretics with complementary mechanisms. Furosemide inhibits the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, leading to increased excretion of sodium, chloride, and water. Spironolactone is a competitive aldosterone antagonist that acts on the distal tubule and collecting duct, reducing sodium reabsorption and potassium excretion. Together, they produce diuresis while mitigating potassium loss.

Mechanism Steps

1
Furosemide inhibits NKCC2: Furosemide blocks the Na-K-2Cl cotransporter in the thick ascending limb of the loop of Henle, preventing sodium and chloride reabsorption.
2
Increased osmotic diuresis: The retained sodium and chloride in the tubule draw water into the urine, increasing urine volume.
3
Spironolactone blocks aldosterone receptors: Spironolactone competitively inhibits aldosterone binding in the distal tubule and collecting duct, reducing sodium reabsorption and potassium secretion.
4
Potassium-sparing effect: By blocking aldosterone, spironolactone reduces potassium excretion, counteracting furosemide-induced potassium loss.
5
Combined diuretic and antihypertensive effect: The net result is enhanced diuresis with a lower risk of hypokalemia and a reduction in blood pressure and edema.

Elderly DosageElderly patients may be more sensitive to the effects of this medicine, especially dizziness and electrolyte imbalances. Start with a lower dose and monitor closely. Dose must be individualized by a qualified clinician.
Renal ImpairmentUse with caution in patients with renal impairment. Dose reduction may be necessary. Monitor renal function and electrolytes closely. In severe renal impairment, this combination may be contraindicated.
Hepatic ImpairmentUse with caution in patients with hepatic impairment. Spironolactone may accumulate in liver disease. Monitor liver function and electrolytes. Dose adjustment may be required.
Maximum Daily DoseThe maximum daily dose should not exceed what is prescribed by your doctor. Typically, the maximum daily dose of furosemide is 600 mg and spironolactone is 400 mg, but the combination dose should be individualized. Do not exceed the prescribed dose.
