This product is colorless or yellowish clear liquid.
Pharmacology and toxicology
This product is a vitamin medicine. Vitamin C participates in amino acid metabolism, neurotransmitter synthesis, collagen synthesis and interstitial synthesis, which can reduce capillary permeability, accelerate blood coagulation, stimulate coagulation function, promote iron absorption in intestine, promote blood lipid reduction, increase anti-infection ability, participate in detoxification function, and have antihistamine effect to prevent carcinogen (nitrosamine) generation.
pharmacokinetics
Protein binding rate is low. A small amount is stored in plasma and cells, and the highest concentration is in glandular tissue. Intrahepatic metabolism. A very small amount of samples or metabolites are excreted through the kidneys. When the plasma concentration is greater than 14mg/ml, the urine volume increases. It can be removed by hemodialysis.
indicate
(1) can be used to treat scurvy, as well as various acute and chronic infectious diseases and purpura.
(2) Treatment of chronic iron poisoning: Vitamin C promotes the chelation of iron by deferoxamine and accelerates the excretion of iron.
(3) Treating idiopathic methemoglobinemia.
(4) In the following cases, the demand for vitamin C will increase:
① Patients received chronic hemodialysis, gastrointestinal diseases (after long-term diarrhea, gastrectomy or ileectomy), tuberculosis, cancer, ulcer, hyperthyroidism, fever, infection, trauma, burns, surgery, etc.
② Patients receiving parenteral nutrition due to strict diet control or choice, patients losing weight due to malnutrition, and patients during pregnancy and lactation;
③ When barbiturates, tetracyclines, salicylic acids or vitamin C are used as acidulants for urinary system.
dosage
Intramuscular or intravenous injection, each time 100 ~ 250 mg for adults, 1 ~ 3 times a day; Children's daily 100 ~ 300 mg, injected in batches. Keshan disease can be treated with a large dose, which is decided by the doctor.
counteraction
(1) Taking 2 ~ 3g daily for a long time can cause scurvy after stopping taking the medicine.
(2) Long-term and large-scale application of vitamin C can cause urate, cysteine or oxalate stones.
(3) Rapid intravenous injection can cause dizziness and fainting.
taboo
Matters needing attention
(1) The role of vitamin C in preventing or treating cancer, gingivitis, suppuration, hemorrhage, hematuria, retinal hemorrhage, depression, dental caries, anemia, acne, infertility, aging, arteriosclerosis, ulcer, tuberculosis, dysentery, collagen disease, fracture, skin ulcer, hay fever, drug poisoning, etc.
(2) Interference diagnosis. A large number of applications will affect the results of the following diagnostic tests:
① occult blood in stool can cause false positive;
② It can interfere with the automatic analysis results of serum lactate dehydrogenase and serum transaminase concentration;
③ Both urine sugar (copper sulfate method) and glucose (oxidase method) can cause false positive;
④ The concentration of oxalate, urate and cysteine in urine increased;
⑤ Serum bilirubin concentration decreased;
⑥ Urine pH decreased.
(3) The following situations should be used with caution:
① Cysteine urine;
② gout;
③ hyperoxaluria;
④ oxalate deposition;
⑤ Uric acid kidney calculi;
6 diabetes (because vitamin C may interfere with the quantification of blood sugar);
⑦ Glucose -6- phosphate dehydrogenase deficiency;
8 hemochromatosis;
Pet-name ruby sideroblastic anemia or thalassemia;
Indications: sickle cell anemia.
(4) Long-term sudden withdrawal of a large number of drugs may lead to scurvy symptoms, so it is advisable to gradually reduce the withdrawal of drugs.
Medication for pregnant and lactating women
This product can be secreted into milk through placenta. When pregnant women use it in large quantities, it will produce scurvy in infants.
Children's medication
Medication for elderly patients
drug interaction
(1) A large dose of vitamin C can interfere with the anticoagulant effect.
(2) Combined with barbital or primidone, the excretion of vitamin C can be increased.
(3) Sodium cellulose phosphate can promote the metabolism of vitamin C to oxalate.
(4) Long-term or large-scale application of vitamin C can interfere with the effect of disulfiram on ethanol.
(5) Salicylic acid can increase the excretion of vitamin C.
(6) It should not be compatible with alkaline drugs (such as aminophylline, sodium bicarbonate, sodium glutamate, etc.). ), riboflavin, trichlorotert-butanol, copper and iron ions (trace) so as not to affect the curative effect.
(7) Compatibility with vitamin K3, because the latter is oxidizing, can produce redox reaction, which weakens or disappears the curative effect of both.
excessive
Daily 1 ~ 4g can cause diarrhea, rash, gastric acid increase and gastric juice reflux, sometimes urinary calculi, increased excretion of oxalate and urate in urine, deep vein thrombosis, intravascular hemolysis or coagulation. Sometimes, it will lead to the decrease of phagocytosis of white blood cells. When the daily dose exceeds 5g, it can lead to hemolysis, and in severe cases, it can be fatal. When pregnant women use it in large quantities, it will produce scurvy in infants. If necessary, adults should take 2 ~ 4g each time, 1 ~ 2 times a day, or as directed by the doctor.
