Ascorbic acid, twist cranberries 10 pcs.

Vitamin C (ascorbic acid) is considered the most broad-spectrum antioxidant, fights free radicals and removes them from the body, supports intensive production of antibodies, increases the body’s resistance to various infections, thanks to the resistance of the cells themselves to penetration of pathogenic agents.

Indications

Prevention and treatment of hypovitaminosis of vitamin C.

In high demand for vitamin C: during active growth in children, pregnancy, breastfeeding, with increased physical and mental exertion, fatigue, stress, recovery period after a long and serious illness.

Composition

1 tablet contains:

Ascorbic acid – 25 mg;

Sucrose (sugar) – 2.064 g;

Glucose (dextrose) – 0.830 g.

Bauxiliary substances:

Potato starch;

Citric acid;

Magnesium stearate;

Natural flavoring.

How to take, the dosage

Ascorbic acid is taken orally, after meals.

Acorbic acid is prescribed for prophylactic purposes:
Adults-50-100 mg/day; children 25 mg/day. During pregnancy and lactation 300 mg/day for 10-15 days, then 100 mg/day.

With a therapeutic purpose is prescribed:
Adults-50-100 mg 3-5 times a day; children 50-100 mg 2-3 times a day.

The duration of treatment depends on the nature and course of the disease and is recommended by the doctor.

Interaction

Ascorbic acid increases the blood concentration of benzylpenicillin and tetracyclines at a dose of 1 g / day increases the bioavailability of ethinylestradiol.

Enhances intestinal absorption of iron preparations (converts trivalent iron to divalent iron).

May increase iron excretion when used concomitantly with deferoxamine.

Acetylsalicylic acid (ASA), oral contraceptives, fresh juices and alkaline drinking reduce absorption and absorption. Concomitant use with ASA increases urinary excretion of ascorbic acid and decreases the excretion of ASA. Asc reduces absorption of ascorbic acid by about 30%.

increases the risk of crystalluria when treated with salicylates and short-acting sulfonamides, delays renal excretion of acids, increases excretion of drugs with an alkaline reaction (including alkaloids).
increases the excretion by the kidneys of alkaline-reactive drugs (including alkaloids) and reduces the blood concentration of prescriptional contraceptives.

Enhances the total clearance of ethanol, which, in turn, reduces the concentration of ascorbic acid in the body.

The drugs of quinoline series (fluoroquinolones, etc.), calcium chloride, salicylates, glucocorticosteroids in long-term use deplete ascorbic acid reserves.

In concomitant use reduces the chronotropic effect of isoprenaline.

In prolonged use or use in high doses may disrupt the disulfiram-ethanol interaction.

In high doses, increases renal excretion of mexiletine.

Barbiturates and primidone increase urinary excretion of ascorbic acid.

Decreases the therapeutic effects of antipsychotic drugs (phenothiazine derivatives), tubal reabsorption of amphetamine and tricyclic antidepressants.

Contraindications

Hypersensitivity to the components of Ascorbic acid.

Do not prescribe high doses in patients with increased blood clotting, thrombophlebitis and tendency to thrombosis, as well as in patients with diabetes and conditions accompanied by high blood sugar.

Overdose

Symptoms with prolonged use of large doses (more than 1 g): Headache, increased central nervous system excitability, insomnia, nausea, vomiting, hyperacid gastritis, gastrointestinal mucosal ulceration, heartburn, diarrhea, difficult urination, staining of urine red, hemolysis (in patients with glucose-6-phosphate dehydrogenase deficiency), inhibition of pancreatic insular function (hyperglycemia, glucosuria), hyperoxaluria, nephrolithiasis (from calcium oxalate), renal glomerular damage, moderate pollakiuria (when taking doses over 600 mg/day).

Decreased capillary permeability (deterioration of tissue trophism, increased blood pressure, hypercoagulation, development of microangiopathies is possible).
