Product information
Vitamin D3 is an active factor against rickets. It is a regulator of calcium-phosphorus exchange and ensures proper mineralization and normal development of bones and teeth. Cholecalciferol, a natural form of vitamin D, is produced in the skin by exposure to sunlight. Compared to vitamin D2, it differs in that its activity is higher than 25%. It is necessary for the normal function of the thyroid gland. It affects the intestines, kidneys and bone system. It plays an important role in the absorption of calcium and phosphates from the intestine, the transport of mineral salts and the calcification of bones, and also regulates the excretion of calcium and phosphates through the kidneys. The concentration of calcium ions affects a number of important biochemical processes that determine the maintenance of the tone of skeletal muscles, the transmission of nerve impulses, and the blood coagulation process. Vitamin D also participates in the functioning of the immune system by affecting the production of lymphokines. In the period of rapid development of the child, lack of vitamin D in food, weakening of its absorption, lack of calcium, lack of exposure to sunlight cause rickets; in adults, it can cause osteomalacia, tetanus symptoms in pregnant women, and disruption of bone hardening processes in newborns. The need for vitamin D increases in menopausal women as a result of the development of osteoporosis, often due to hormonal disorders.
An aqueous solution of vitamin D3 is better absorbed than an oily solution. In premature babies, the absorption of vitamins in the form of a fat solution is impaired because the production of bile and its entry into the duodenum are insufficient. After oral administration, cholecalciferol is absorbed in the small intestine. It undergoes metabolism in the liver and kidneys. The half-life of cholecalciferol is several days. The drug easily passes through the placental barrier. Penetrates into breast milk. It is excreted from the body with urine and faeces.

Instructions for use
Recommended as an additional source of vitamin D in the following situations: 
- Prevention and treatment of vitamin D deficiency or deficiency
- Due to the violation of the absorption of vitamin D in the gastrointestinal tract (malabsorption syndrome, 
chronic diarrheas, enteropathies, pancreatitis) prevention and treatment of vitamin D deficiency
- Prevention and treatment of rickets and rickets-like diseases
- Metabolic osteopathies (hypoparathyroidism, pseudohypoparathyroidism)
- Tetany, convulsions caused by hypocalcemia
- Secondary hyperparathyroidism (increase in the level of parathormone, which regulates calcium metabolism in the body)
- Risk of fractures due to decreased bone volume (osteomalacia) (supportive treatment)
- Complex treatment of osteoporosis (including postmenopausal osteoporosis).
Contraindications
Hypersensitivity to cholecalciferol (vitamin D3) or any of the excipients, high blood pressure (hypertension), atherosclerosis, active pulmonary tuberculosis, hypervitaminosis D, increased levels of calcium in the blood and urine, oxalate kidney stones (nephrolithiasis, nephrocalcinosis), renal failure .

Method of use and dosage  
Always use SUN DROPS as directed by your doctor. 
1 ml (20 drops) of solution contains 8000 BV, 1 drop contains 400 BV of cholecalciferol (vitamin D3).

Rickets disease:5-12 drops (2000-5000 BV)/day every day for 4-6 weeks, depending on the severity and course of the disease, with strict control of the clinical condition, examination of biochemical indicators of blood and urine (calcium, phosphorus, alkaline phosphatases). Treatment is started with a dose of 1000 IU for 3-5 days, then the dose is increased to an individual therapeutic dose (usually 3000 IU/day) if the drug is well accepted by the body. A daily dose of 5000 BV is applied only if there are clearly expressed changes in the bone. If necessary, the course of treatment can be repeated after a week break. The treatment is carried out until the exact therapeutic effect is obtained, then it is transferred to a preventive dose (1-4 drops (400-1600 BV)/day). 
Rickets-like diseases:50-75 drops (20,000-30,000 IU)/day, depending on age, body weight and severity of the disease, monitoring biochemical indicators of blood and urine. The course of treatment is 4-6 weeks. Treatment is carried out under the supervision of a doctor.
Complex treatment of osteoporosis:1-3 drops (400-1200 BV)/day.
Osteomalacia caused by vitamin D deficiency: 25 drops (10,000 IU)/day, maintenance dose 3-5 drops (1,200-2,000 IU)/day.
