Complivit Calcium D3, orange 100 pcs

Pharmacotherapeutic group: calcium-phosphorus metabolism regulator.

ATC code: [A12AX].

Pharmacological properties

Pharmacodynamics

Combined drug regulating calcium and phosphorus metabolism in the body (bones, teeth, nails, hair, muscles). It reduces resorption (resorption) and increases bone density, compensating the lack of calcium and vitamin D₃ in the body, increases absorption of calcium in the intestine and reabsorption of phosphate in the kidneys, promotes mineralization of bones and teeth.

Calcium is involved in the formation of bone tissue, in maintaining a stable cardiac function, in the regulation of nerve conduction, muscle contractions, production of hormones and is a component of the blood clotting system.

The adequate intake of calcium is especially important during growth, pregnancy and lactation.

Vitamin D₃ (colecalciferol) increases the absorption of calcium in the intestine and promotes the formation and mineralization of bone and dental tissue.

The use of calcium and vitamin D₃ prevents increased production of parathyroid hormone (PTH), which is a stimulant of increased bone resorption (leaching of calcium from bone).

Pharmacokinetics.

Calcium

Intake: Calcium is absorbed in ionized form in the proximal small intestine through an active, D-vitamin dependent transport mechanism. Typically, the amount of calcium absorbed in the gastrointestinal tract is approximately 30% of the dose taken.

Distribution and metabolism: 99% of calcium in the body is concentrated in the hard structure of the bones and teeth. The remaining 1% is in intra- and extracellular fluids.

Excretion: calcium is excreted by the intestines, kidneys and sweat glands. Renal excretion depends on glomerular filtration and tubular reabsorption of calcium.

Vitamin D3

Intake: Vitamin D₃ is easily absorbed in the small intestine (about 80% of the dose taken).

Distribution and metabolism: coleciferol and its metabolites circulate in the blood, bound to a specific globulin. Colocalciferol is converted in the liver by hydroxylation to 25-hydroxycalciferol.

It is then converted in the kidneys to the active form 1,25-hydroxycalciferol, responsible for increasing calcium absorption in the intestine and tubular reabsorption in the kidneys. Unmetabolized vitamin D₃ is deposited in fat and muscle tissue. 3 is excreted by the intestine and kidneys.

Indications

Prevention and treatment of calcium and/or vitamin D3 deficiency.

Prevention and comprehensive therapy of osteoporosis and its complications (bone fractures).

How to take, the dosage

Complivit® Calcium D3, chewable tablets, apply inally with meals. The tablet should be chewed or sucked. After that, if necessary, it can be drunk with water.

Adults: for treatment of osteoporosis – 1 tablet 2-3 times a day, to prevent osteoporosis – 1 tablet 2 times a day.

In case of calcium and/or vitamin D3 deficiency:

Adults and children over 12 years – 1 tablet 2 times a day.

Children from 5 years to 12 years – 1 to 2 tablets per day.

In children from 3 to 5 years of age, the dosage according to the doctor’s recommendation.

Special patient groups

Patients with impaired liver function:

Dose adjustment is not required.

Patients with impaired renal function:

The drug should not be used in severe renal failure.

Elderly patients:

The dose is the same as for adults. Possible decreased creatinine clearance should be considered.

The duration of treatment

When used for prevention and in complex therapy of osteoporosis the duration of treatment is determined by the doctor individually.

When using for replenishment of calcium and/or vitamin D3 deficiency the average duration of treatment course is at least 4-6 weeks. The number of repeated courses within a year is determined individually.

Interaction

Vitamin D3 activity may decrease when used concomitantly with phenytoin or barbiturates.

Hypercalcemia may potentiate toxic effects of cardiac glycosides when used simultaneously with calcium and vitamin D preparations. Monitoring of ECG and serum calcium content is necessary.

Calcium preparations may decrease absorption of tetracyclines from the gastrointestinal tract. Therefore tetracyclines should be taken at least 2 hours before or 4-6 hours after taking Complivit® Calcium D3.

In order to prevent reduced absorption of bisphosphonate preparations, it is recommended that they be taken at least one hour before taking Complivit® Calcium D3.

Glucocorticosteroids decrease calcium absorption, so treatment with glucocorticosteroids may require increasing the dose of Complivit® Calcium D3.

Concomitant treatment with colesteramine preparations or mineral or vegetable oil-based laxatives may decrease vitamin D3 absorption.

The concomitant use of thiazide-type diuretics increases the risk of hypercalcemia because they increase the tubular reabsorption of calcium. When concomitant use of thiazide diuretics, serum calcium content should be regularly monitored. In contrast, furosemide and other “loop” diuretics increase renal calcium excretion.

Calcium reduces the effectiveness of levothyroxine by reducing its absorption. The time period between levothyroxine and Complivit® Calcium D3 should be at least 4 hours.

The absorption of antibiotics of the quinolone group is reduced when used concomitantly with calcium preparations. Therefore, antibiotics of quinolone group should be taken 2 hours before or 6 hours after taking Complivit® Calcium D3.

The intake of foods containing oxalates (sorrel, rhubarb, spinach) and phytin (cereals) reduces calcium absorption, so you should not take Complivit.sup>® Calcium D3 within 2 hours of eating sorrel, rhubarb, spinach, and cereals.

Special Instructions

Serum calcium and creatinine should be monitored during long-term therapy. Monitoring is especially important in elderly patients with concomitant treatment with cardiac glycosides and diuretics (see section “Interaction with other medicinal products and foodstuffs”) and in patients with increased propensity to form kidney stones.

In cases of hypercalcemia or signs of impaired renal function, the dose should be reduced or treatment stopped.

Vitamin D3 should be taken with caution in patients with renal insufficiency. In this case it is necessary to control the content of calcium and phosphate in serum. Also the risk of soft tissue calcinosis should be considered.

In order to avoid an overdose, additional vitamin D intake from other sources must be considered.

In the elderly, the need for calcium is 1,500 mg/day and vitamin D3 is 0.5-1,000 IU/day.

Calcium and vitamin D3 should be used with caution in immobilized patients with osteoporosis because of the risk of hypercalcemia.

Simultaneous use with antibiotics of the tetracycline or quinolone group is generally not recommended or should be used with caution (see section “Interaction with other drugs and foods”).

Impact on the ability to drive vehicles and machines.

The Complivit® Calcium D3 drug does not affect the ability to drive vehicles or operate technically complex machinery.
