🇮🇳 calcilac tablet के बारे में (Hindi Summary)

उपयोग: यह दवा कैल्शियम और विटामिन डी3 का संयोजन है, जिसका उपयोग शरीर में इन पोषक तत्वों की कमी को पूरा करने के लिए किया जाता है। यह हड्डियों को मजबूत बनाने, ऑस्टियोपोरोसिस, ऑस्टियोमलेशिया और रिकेट्स जैसी हड्डियों की बीमारियों में सहायक उपचार के रूप में दी जाती है। यह उन लोगों के लिए भी फायदेमंद है जिनके आहार में कैल्शियम और विटामिन डी की मात्रा कम है या जो धूप में कम समय बिताते हैं। यह दवा मांसपेशियों की ऐंठन, हड्डियों के दर्द और कमजोरी में भी राहत देने में मदद कर सकती है। इसे डॉक्टर की सलाह के अनुसार ही लेना चाहिए।

साइड इफेक्ट्स: इस दवा को लेने पर आमतौर पर हल्के पेट संबंधी विकार जैसे कब्ज, पेट फूलना, जी मिचलाना और चॉकी स्वाद महसूस हो सकता है। ये लक्षण आमतौर पर अस्थायी होते हैं और भोजन के साथ दवा लेने पर कम हो जाते हैं। कभी-कभी दस्त, पेट में ऐंठन या भूख में कमी भी हो सकती है। गंभीर दुष्प्रभाव दुर्लभ हैं, लेकिन अधिक मात्रा में लेने पर रक्त में कैल्शियम बढ़ सकता है, जिससे गुर्दे की पथरी या किडनी की समस्या हो सकती है। अगर आपको चक्कर, अत्यधिक प्यास, बार-बार पेशाब या मांसपेशियों में कमजोरी महसूस हो, तो तुरंत डॉक्टर से संपर्क करें।

सुरक्षा सलाह: इस दवा को डॉक्टर द्वारा बताई गई मात्रा में ही लें और अपने मन से मात्रा न बढ़ाएं। इसे भोजन के साथ और पूरे गिलास पानी के साथ लें, इससे अवशोषण बेहतर होता है और पेट की तकलीफ कम होती है। अगर आप लेवोथायरॉक्सिन, आयरन, जिंक, टेट्रासाइक्लिन या डॉक्सीसाइक्लिन जैसी दवाएं लेते हैं, तो इस दवा और उनके बीच कम से कम दो घंटे का अंतर रखें। गुर्दे की बीमारी, पथरी, हाई ब्लड कैल्शियम या सारकॉइडोसिस होने पर डॉक्टर को जरूर बताएं। गर्भावस्था या स्तनपान के दौरान इसका उपयोग डॉक्टर की सलाह के बिना न करें। बच्चों की पहुंच से दूर रखें।

🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionCalcium absorption occurs mainly in the duodenum and proximal jejunum and is enhanced by the vitamin D3 in this medicine. Absorption is most efficient when the supplement is taken with food and in divided doses rather than as a single large dose. Vitamin D3 is absorbed in the small intestine along with dietary fats and requires bile salts and pancreatic lipase for efficient uptake.

DistributionCalcium is distributed throughout the body, with approximately 99% stored in bones and teeth and the remaining 1% in blood and soft tissues. Vitamin D3 and its metabolites are transported in the blood bound to vitamin D-binding protein and are distributed to the liver, kidney, bone, intestine, and other tissues.

Protein BindingCalcium in the blood is partly bound to albumin and other plasma proteins, with the free ionized fraction being the physiologically active form. Vitamin D3 and its metabolites are strongly bound to vitamin D-binding protein and, to a lesser extent, to albumin and lipoproteins.

MetabolismCalcium is not metabolized in the conventional sense; it is absorbed, used, stored, and excreted. Vitamin D3 is metabolized in the liver to calcifediol by cytochrome P450 enzymes, mainly CYP2R1, and then in the kidney to calcitriol by CYP27B1. Calcitriol is further inactivated by CYP24A1.

Half-LifeThe elimination half-life of calcium from the body is not usually expressed as a single value because calcium is continuously exchanged between bone, blood, and other tissues. The half-life of calcifediol is approximately two to three weeks, while calcitriol has a much shorter half-life of about four to six hours.

ExcretionUnabsorbed calcium is excreted in the feces, and absorbed calcium is excreted mainly in the urine and, to a smaller extent, in sweat and bile. Vitamin D metabolites are excreted primarily in bile and feces, with small amounts in urine.

BioavailabilityThe bioavailability of calcium from this supplement depends on the calcium salt, the dose, and the presence of food and vitamin D. It is generally higher when taken with meals and in divided doses. Vitamin D3 bioavailability is good when taken with dietary fat.

Onset of ActionThe onset of action for correcting calcium and vitamin D deficiency is gradual and is usually measured in weeks rather than hours. Symptomatic improvement in deficiency-related bone pain may take several weeks of consistent use.

Peak Plasma TimeSerum calcium levels rise within a few hours after an oral dose, but the full effect on bone and mineral balance develops over days to weeks. Vitamin D3 levels increase more slowly, with peak calcifediol levels typically reached after several days to weeks of regular dosing.

Duration of ActionThe effect of a single dose on serum calcium lasts for several hours, while the beneficial effects on bone and mineral metabolism persist as long as the supplement is taken regularly. After stopping, vitamin D levels decline gradually over weeks.

How It Works

This medicine works through the combined actions of calcium and vitamin D3. Calcium is a structural mineral that is deposited in bone as calcium phosphate and calcium carbonate, providing mechanical strength to the skeleton. It also participates in muscle contraction, nerve conduction, blood clotting, and hormone secretion. Vitamin D3, or cholecalciferol, is converted in the liver to calcifediol and then in the kidney to calcitriol, the active hormone form. Calcitriol binds to vitamin D receptors in the intestine, bone, kidney, and parathyroid glands. In the intestine, it increases the production of calcium-binding proteins that carry calcium across the gut wall into the bloodstream. In bone, it helps regulate the balance between bone formation and bone resorption. In the kidney, it promotes calcium reabsorption, and in the parathyroid glands it reduces parathyroid hormone secretion. Together, these actions raise the amount of calcium available for bone mineralization and help maintain normal blood calcium levels.

Mechanism Steps

1

Calcium dissolution and absorption: The calcium salt in this medicine dissolves in the stomach and is absorbed mainly in the small intestine, where vitamin D3 enhances its uptake.

2

Vitamin D3 activation: Vitamin D3 is converted in the liver to calcifediol and then in the kidney to calcitriol, the biologically active form.

3

Vitamin D receptor binding: Calcitriol binds to vitamin D receptors in the intestine, bone, kidney, and parathyroid glands, altering gene expression.

4

Increased calcium transport: In the intestine, calcitriol increases the synthesis of calcium-binding proteins that carry calcium into the bloodstream.

5

Bone mineralization: The absorbed calcium and phosphate are deposited in bone as mineral crystals, improving bone density and strength.

6

Parathyroid hormone suppression: Rising calcium levels reduce parathyroid hormone secretion, which lowers bone resorption and helps maintain calcium balance.

Dosage Information

Adult Dosage	The usual adult dose of this medicine is one tablet taken orally once daily, preferably with a meal, or as directed by your doctor. The exact dose and duration depend on the indication, your dietary calcium intake, your vitamin D status, and any other medicines you take. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function. Do not take more than the prescribed dose without medical advice.
Pediatric Dosage	Pediatric dosing is not established from available information. Consult a pediatrician.
Elderly Dosage	Older adults often need calcium and vitamin D supplementation, but the dose should be individualized by a clinician because kidney function and the risk of hypercalcemia increase with age. Regular monitoring of calcium and vitamin D levels is advised.
Renal Impairment	Use with caution in people with kidney disease. The dose may need to be reduced or the supplement avoided in severe renal impairment because the kidneys play a key role in calcium excretion and vitamin D activation. Dose must be individualized by a qualified clinician based on renal function.
Hepatic Impairment	No specific dose adjustment is usually required for mild to moderate liver disease. In severe liver disease, vitamin D activation may be impaired, and the dose should be individualized by a qualified clinician.
Maximum Daily Dose	The maximum daily dose should not exceed the amount prescribed by your doctor. In general, total elemental calcium intake from all sources should not exceed 2000 mg per day for most adults, and vitamin D intake should not exceed the recommended upper limit for your age and condition. Always follow your clinician's advice.
