🇮🇳 lsrab capsule के बारे में (Hindi Summary)

उपयोग: यह दवा रेबेप्राजोल नामक सक्रिय तत्व से बनी है, जो प्रोटॉन पंप इनहिबिटर वर्ग की दवा है। इसका उपयोग एसिड रिफ्लक्स, गैस्ट्रोएसोफेजियल रिफ्लक्स डिजीज (जीईआरडी), पेट और आंतों के अल्सर, और हेलिकोबैक्टर पाइलोरी संक्रमण के इलाज में किया जाता है। यह पेट में एसिड का उत्पादन कम करके लक्षणों से राहत देती है।

साइड इफेक्ट्स: आम दुष्प्रभावों में सिरदर्द, दस्त, पेट दर्द, मतली और गैस शामिल हैं। गंभीर दुष्प्रभाव दुर्लभ हैं लेकिन एलर्जी, किडनी की समस्या, और मैग्नीशियम की कमी हो सकती है। लंबे समय तक उपयोग से हड्डियों के फ्रैक्चर का खतरा बढ़ सकता है।

सुरक्षा सलाह: इस दवा को डॉक्टर के निर्देशानुसार ही लें। कैप्सूल को चबाएं या तोड़ें नहीं, पूरा निगल लें। इसे आमतौर पर दिन में एक बार भोजन से पहले लिया जाता है। शराब का सेवन न करें क्योंकि इससे पेट में जलन बढ़ सकती है। यदि आप गर्भवती हैं या स्तनपान करा रही हैं तो डॉक्टर को बताएं। बच्चों की पहुंच से दूर रखें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionRabeprazole is rapidly absorbed after oral administration, with peak plasma concentrations occurring approximately 2 to 5 hours after dosing. The absolute bioavailability is approximately 52% due to first-pass metabolism. Food does not significantly affect the absorption of rabeprazole.
DistributionRabeprazole is approximately 96% bound to plasma proteins. It is widely distributed to tissues, including the gastric mucosa. The volume of distribution is not well established.
Protein BindingApproximately 96% bound to plasma proteins.
MetabolismRabeprazole is extensively metabolized in the liver, primarily by the cytochrome P450 enzyme system, specifically CYP2C19 and CYP3A4. Its major metabolites are inactive.
Half-LifeThe elimination half-life of rabeprazole is approximately 1 to 2 hours. However, the duration of acid suppression is much longer due to irreversible binding to the proton pump.
ExcretionRabeprazole is excreted mainly as metabolites in the urine (approximately 90%) and feces (approximately 10%). Less than 1% is excreted unchanged in urine.
BioavailabilityThe absolute bioavailability of rabeprazole is approximately 52%.
Onset of ActionAcid suppression begins within 1 hour after oral administration.
Peak Plasma TimePeak plasma concentrations are reached approximately 2 to 5 hours after dosing.
Duration of ActionThe duration of acid suppression is approximately 24 hours, allowing once-daily dosing.

How It Works

Rabeprazole is a proton pump inhibitor that works by irreversibly blocking the hydrogen-potassium adenosine triphosphatase enzyme system, also known as the proton pump, located in the parietal cells of the stomach. This enzyme is responsible for the final step in gastric acid secretion. By inhibiting this pump, rabeprazole suppresses both basal and stimulated acid secretion, leading to a significant reduction in stomach acid levels. This action helps to heal acid-related damage and relieve symptoms.

Mechanism Steps

1
Accumulation in acidic environment: Rabeprazole is a weak base and accumulates in the acidic environment of the parietal cell secretory canaliculi.
2
Activation to sulfenamide: In the acidic environment, rabeprazole is converted to its active form, a sulfenamide derivative.
3
Binding to proton pump: The active form binds covalently to cysteine residues on the H+/K+ ATPase enzyme, irreversibly inhibiting its function.
4
Inhibition of acid secretion: This binding prevents the exchange of hydrogen ions for potassium ions, thereby blocking the final step of acid production.
5
Suppression of acid output: As a result, both basal and stimulated gastric acid secretion are significantly reduced, allowing healing of acid-related damage.

Dosage Information

Adult DosageThe usual adult dose of this medicine is 20 mg once daily for most indications such as gastroesophageal reflux disease and peptic ulcer disease. For Helicobacter pylori eradication, it is typically used in combination with antibiotics for 7 to 14 days. The dose may be adjusted based on the condition being treated and the patient's response. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageNo specific dosage adjustment is required for elderly patients, but they may be more susceptible to side effects such as bone fractures and hypomagnesemia. Use with caution.
Renal ImpairmentNo dosage adjustment is necessary for patients with renal impairment.
Hepatic ImpairmentFor patients with severe hepatic impairment, a lower dose may be considered. Consult a doctor for individualized dosing.
Maximum Daily DoseThe maximum recommended daily dose is 20 mg for most indications, but up to 60 mg daily has been used in Zollinger-Ellison syndrome under medical supervision.
