Description

A kind of calcium gluconate sodium chloride injection and preparation method thereof
Technical field
The present invention relates to a kind of injection, specifically, relate to a kind of calcium gluconate sodium chloride injection.
Background technology
Calcium gluconate, chemical name is maltonic acid hydrate of calcium, and molecular formula is C 12h 22caO 14h 2o, molecular weight is 448.40, and structural formula is as follows:
Calcium gluconate is white crystalline or graininess powder, and odorless, tasteless, is soluble in boiling water, is slightly dissolved in cold water, is insoluble to the organic solvent such as ethanol or ether.
Calcium gluconate injection is calcium complement agent.Calcium can maintain nervimuscular NE, promotes teleneuron secretion acetylcholine.Serum calcium can occur that neural muscle excitability improves, and twitches when reducing, and the too high then irritability of blood calcium reduces, and occurs weakness etc.Calcium ion can improve membrane passage, increases the compactness of capillary tube, makes to ooze out minimizing, plays anti-allergic effects.Calcium ion can promote that the calcification of skeleton and tooth is formed.There is competitive antagonism between high concentration calcium ion and magnesium ion, can be used for the rescue that magnesium is poisoning.Calcium ion can generate insoluble calcium fluoride with fluoride, can be used for the rescue of fluorosis.Calcium gluconate injection is also applied when cardiac resuccitation, for hyperkalemia or low blood calcium, or the rescue of New function exception that this channel blocking causes.
In the prior art, calcium gluconate injection is small-volume injection product, and the dissolubility of calcium gluconate in water is 3.33%, and the specification of product is the concentration of 10%, is supersaturated solution.Therefore, between the storage life, easily there is crystallization.In traditional prescription, lactic acid and calcium hydroxide generate calcium lactate, though certain hydrotropy effect can be played to calcium gluconate, but calcium gluconate can only be made not occur crystallization at short notice, along with the prolongation of period of storage, especially under cryogenic, the dissolubility of calcium gluconate reduces gradually, makes saturated calcium gluconate crystallization gradually.In addition, small-volume injection in use easily causes secondary pollution owing to repeatedly puncturing, and ampoule bottle exists chips of glass hidden danger when opening simultaneously.
