🇮🇳 adtrol xt tablet के बारे में (Hindi Summary)

उपयोग: यह दवा कैल्शियम और विटामिन डी3 की कमी को पूरा करने के लिए दी जाती है। यह हड्डियों की मजबूती के लिए जरूरी है और ऑस्टियोपोरोसिस, ऑस्टियोमलेशिया और रिकेट्स जैसी हड्डियों की बीमारियों में मदद करती है। यह मांसपेशियों की ऐंठन, हड्डियों के दर्द और थकान को कम करने में सहायक है। गर्भवती महिलाओं, स्तनपान कराने वाली माताओं और बुजुर्गों में कैल्शियम की बढ़ी हुई आवश्यकता को पूरा करने के लिए भी इसका उपयोग किया जाता है।

साइड इफेक्ट्स: इस दवा के सामान्य दुष्प्रभावों में कब्ज, पेट में गैस, सूजन, जी मिचलाना और पेट खराब होना शामिल हैं। ये आमतौर पर हल्के होते हैं और कुछ समय में ठीक हो जाते हैं। दवा को भोजन के साथ लेने से ये लक्षण कम हो सकते हैं। कभी-कभी मुंह सूखना या धातु जैसा स्वाद आ सकता है। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अगर आपको भ्रम, अत्यधिक प्यास, बार-बार पेशाब आना या गंभीर जी मिचलाना हो तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा को डॉक्टर के बताए अनुसार ही लें। खुराक से अधिक न लें। गोली को पूरा निगलें और साथ में एक गिलास पानी पिएं। इसे भोजन के साथ लेना बेहतर होता है। पर्याप्त पानी पीते रहें। अगर आपको किडनी की बीमारी, किडनी में पथरी या खून में कैल्शियम की अधिकता है तो डॉक्टर को बताएं। लंबे समय तक लेने पर कैल्शियम और किडनी की जांच कराते रहें। बच्चों की पहुंच से दूर रखें। ठंडी और सूखी जगह पर स्टोर करें।

💡 Did You Know? The first generic medicine was introduced in India in 1970 after the Patents Act was amended.

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCalcium absorption occurs primarily in the duodenum and proximal jejunum and is enhanced by vitamin D. Absorption is saturable and depends on the dose and the presence of food. Vitamin D3 is well absorbed from the small intestine in the presence of bile salts.
DistributionCalcium is distributed to bones, teeth, and extracellular fluids. About 99% of body calcium is stored in bones. Vitamin D3 and its metabolites are transported in the blood bound to vitamin D-binding protein.
Protein BindingCalcium is approximately 40% bound to plasma proteins, mainly albumin. Vitamin D metabolites are highly bound to vitamin D-binding protein.
MetabolismVitamin D3 is metabolized in the liver to 25-hydroxyvitamin D and in the kidney to 1,25-dihydroxyvitamin D. Calcium is not metabolized.
Half-LifeCalcium is eliminated primarily via the kidneys and feces. The half-life of 25-hydroxyvitamin D is about 2-3 weeks; calcitriol has a half-life of 5-8 hours.
ExcretionUnabsorbed calcium is excreted in feces. Absorbed calcium is excreted mainly in urine and feces. Vitamin D metabolites are excreted in bile and urine.
BioavailabilityCalcium absorption from Calcium Carbonate is about 30% under normal conditions and increases with vitamin D. Vitamin D3 bioavailability is good when taken with a fat-containing meal.
Onset of ActionCalcium effects on serum levels occur within hours; vitamin D effects on calcium absorption take days to weeks.
Peak Plasma TimeSerum calcium peaks 2-4 hours after oral intake. Vitamin D3 peak levels occur 4-12 hours after ingestion.
Duration of ActionCalcium effects last several hours; vitamin D effects persist for days to weeks due to its long half-life.

How It Works

This medicine works by supplying elemental calcium and vitamin D3. Calcium Carbonate neutralizes gastric acid and releases calcium ions, which are essential for bone formation, muscle function, nerve signaling, and blood coagulation. Vitamin D3 (cholecalciferol) is converted in the liver and kidney to its active form, calcitriol, which promotes intestinal absorption of calcium and phosphate, stimulates bone mineralization, and regulates parathyroid hormone levels. Together, they help maintain normal calcium homeostasis and bone health.

Mechanism Steps

1
Calcium dissolution: Calcium Carbonate dissolves in the stomach acid to release calcium ions.
2
Vitamin D activation: Vitamin D3 is hydroxylated in the liver to 25-hydroxyvitamin D and then in the kidney to 1,25-dihydroxyvitamin D (calcitriol).
3
Intestinal calcium absorption: Calcitriol binds to vitamin D receptors in the intestine, increasing the production of calcium-binding proteins that facilitate calcium uptake.
4
Bone mineralization: Calcium and phosphate are deposited into the bone matrix, maintaining bone strength and structure.
5
Parathyroid regulation: Elevated calcium levels suppress parathyroid hormone release, reducing bone resorption and renal calcium excretion.

Dosage Information

Adult DosageThe usual adult dose is one tablet once daily or as directed by a physician. Dosage may vary based on the indication, severity of deficiency, and individual patient factors. For osteoporosis, it is often combined with other medications. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not self-adjust the dose.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician for appropriate dosing in children.
Elderly DosageElderly patients may require lower doses due to reduced renal function. Regular monitoring of serum calcium and renal function is advised. Dose must be individualized by a qualified clinician.
Renal ImpairmentUse with caution in patients with renal impairment. Dose reduction may be necessary. Monitor serum calcium and renal function closely. Consult a nephrologist for guidance.
Hepatic ImpairmentNo specific dose adjustment is established for hepatic impairment. Use with caution and monitor as clinically indicated.
Maximum Daily DoseThe maximum daily dose should not exceed the prescribed amount. Typically, one tablet daily is recommended, but the maximum safe dose depends on individual calcium and vitamin D requirements. Do not exceed the dose recommended by your doctor.

🍽️ Food Timing Guide

With meals
Take with food
Enhances absorption and reduces stomach upset.
Oxalate-rich foods (spinach, rhubarb)
Avoid taking together
Oxalates bind calcium and reduce absorption.
Phytate-rich foods (whole grains, bran)
Separate by 2 hours
Phytates interfere with calcium absorption.
Caffeine
Limit intake
Caffeine increases calcium excretion.
