🇮🇳 ritocal ct 0.25mcg tablet के बारे में (Hindi Summary)

उपयोग: यह दवा कैल्सिट्रियोल 0.25 mcg कैप्सूल है, जो विटामिन डी3 का सक्रिय रूप है। इसका उपयोग क्रोनिक किडनी रोग, हाइपोपैराथायरायडिज्म, और विटामिन डी-प्रतिरोधी रिकेट्स जैसी स्थितियों में कैल्शियम के स्तर को बढ़ाने के लिए किया जाता है। यह आंतों में कैल्शियम के अवशोषण को बढ़ाता है और पैराथायरायड हार्मोन को कम करता है। यह दवा डॉक्टर के पर्चे के बिना नहीं लेनी चाहिए।

साइड इफेक्ट्स: आम दुष्प्रभावों में मतली, उल्टी, कब्ज, मुंह सूखना, सिरदर्द और कमजोरी शामिल हैं। गंभीर दुष्प्रभावों में हाइपरकैल्सीमिया (कैल्शियम का बढ़ना) हो सकता है, जिससे भ्रम, अत्यधिक प्यास, बार-बार पेशाब आना, अनियमित दिल की धड़कन और गुर्दे की पथरी हो सकती है। यदि आपको लगातार मतली, उल्टी या कैल्शियम बढ़ने के लक्षण दिखें तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। खुराक से अधिक न लें। कैल्शियम, फॉस्फेट और गुर्दे की कार्यप्रणाली की नियमित जांच कराएं। डॉक्टर की सलाह के बिना कैल्शियम या विटामिन डी की खुराक न लें। पर्याप्त पानी पिएं। यदि आप गर्भवती हैं, गर्भवती होने की योजना बना रही हैं, या स्तनपान करा रही हैं तो डॉक्टर को बताएं। शराब से बचें। दवा को ठंडी, सूखी जगह पर धूप से दूर रखें। बच्चों की पहुंच से दूर रखें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCalcitriol is rapidly absorbed from the gastrointestinal tract after oral administration. Peak plasma concentrations are reached within 2 to 6 hours.
DistributionCalcitriol is distributed widely in the body, primarily bound to vitamin D-binding protein and albumin. It crosses the placenta and is excreted in breast milk.
Protein BindingApproximately 99.9% bound to plasma proteins, mainly vitamin D-binding protein and albumin.
MetabolismCalcitriol is metabolized in the liver and kidney to less active metabolites, including calcitroic acid.
Half-LifeThe elimination half-life of calcitriol is approximately 5 to 8 hours.
ExcretionCalcitriol and its metabolites are excreted primarily in bile and feces, with a small amount excreted in urine.
BioavailabilityThe oral bioavailability of calcitriol is approximately 70% to 80%.
Onset of ActionThe onset of action for increasing serum calcium is within 2 to 6 hours after oral administration.
Peak Plasma TimePeak plasma concentrations are achieved within 2 to 6 hours after oral administration.
Duration of ActionThe duration of action is approximately 3 to 5 days, but this can vary based on individual patient factors and dose.

How It Works

Calcitriol is the active form of vitamin D3. It binds to the vitamin D receptor (VDR) in target tissues, including the intestine, bone, kidney, and parathyroid glands. This binding leads to increased intestinal calcium absorption, increased renal calcium reabsorption, and decreased parathyroid hormone secretion. It also promotes bone mineralization and regulates cell differentiation and immune function.

Mechanism Steps

1
Binding to vitamin D receptor: Calcitriol binds to the vitamin D receptor (VDR) in the cytoplasm of target cells.
2
Receptor activation and gene transcription: The calcitriol-VDR complex enters the nucleus and binds to vitamin D response elements (VDREs) on DNA, regulating gene transcription.
3
Increased calcium absorption: This leads to increased synthesis of calcium-binding proteins in the intestine, enhancing calcium absorption.
4
Renal calcium reabsorption: Calcitriol increases calcium reabsorption in the distal tubules of the kidney.
5
Suppression of PTH: Calcitriol directly suppresses parathyroid hormone synthesis and secretion, reducing bone resorption.

For hypoparathyroidism, the dose may range from 0.25 mcg to 2 mcg daily. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function, and serum calcium levels.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the effects of calcitriol, especially regarding hypercalcemia. Dose should be individualized and monitored closely.
Renal ImpairmentIn patients with renal impairment, calcitriol should be used with caution. Dose adjustment may be necessary based on serum calcium and phosphate levels. Regular monitoring is required.
Hepatic ImpairmentIn patients with hepatic impairment, calcitriol metabolism may be altered. Dose adjustment may be necessary and monitoring is recommended.
Maximum Daily DoseThe maximum recommended daily dose is 2 mcg, but this may vary based on the condition being treated and the patient's response. Do not exceed the dose prescribed by your doctor.
