Description

The compositions of cefmetazole acid and sodium citrate
Technical field
The present invention relates to a kind of compositions, be specifically related to the compositions of a kind of antibiotics cefmetazole acid and sodium citrate.
Background technology
Cefmetazon (Sankyo) (Cefmetazole Sodium) is the novel cephalosporin class antibiotic that three common companies develop alone the earliest, three altogether companies obtain permission in August, 1978 with the trade name of Cefmetazon, start selling injection from February, 1980, the Cefmetazon (Sankyo) chemistry is by name: sulfur (6R-cis)-7-[[[(cyanogen methyl)] acetyl] amido]-7-methoxy-3-[[(1-methyl isophthalic acid H-5-tetrazole base) sulfur]-methyl]-8-oxo-5-thia-1-azabicyclic [4.2.0] oct-2-ene-2-carboxylic acid sodium salt.Structural formula is shown below:
Figure G2009102335988D00011
Its active component is a cefmetazole acid, but because its polarity is less, poorly water-soluble, use for convenient clinically, make dosage form with its sodium salt, cefmetazole acid commonly used adds sodium carbonate or sodium bicarbonate becomes sodium salt, regulate about pH=6, adopt freeze-dry process to prepare freeze-dried powder then.But cefmetazole acid sodium itself does not have crystal formation, so character less stable, the cefmetazole acid structure easily changes in freeze-drying process and in the follow-up storage, be transformed into other material, in quality standard control, other its related substances is higher, simultaneously since impurity content than higher, side reaction and anaphylaxis easily produce the secondary injury than higher to patient in clinical use.
Summary of the invention
Goal of the invention: technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of product quality height and steady quality are provided, the compositions of the novel cefmetazole acid of large-scale industrial production preferably.
Technical scheme: in order to realize above purpose, the compositions with antibacterial action of the present invention, it is made up of cefmetazole acid and sodium citrate.
Compositions with antibacterial action of the present invention, the weight ratio of cefmetazole acid and sodium citrate is 1: 0.4 to 1: 2 in the compositions.
As preferred version, the weight ratio of cefmetazole acid and sodium citrate is 1: 0.4 to 1: 0.8 in the compositions.
As preferred scheme, the weight ratio of cefmetazole acid and sodium citrate is 1: 0.65 in the compositions.
Compositions with antibacterial action of the present invention, have wherein that cefmetazole acid is antimicrobial active component in the compositions of antibacterial action, it and sodium citrate are used in combination, sodium citrate is as cosolvent, can effectively solve the difficult problem of cefmetazole acid poorly water-soluble, and the bactericidal composition formed of cefmetazole acid and sodium citrate injection or the injectable powder steady quality made, can long term storage, be difficult for being transformed into other materials through the experimentation cefmetazole acid, impurity content is few, can make things convenient for to formulate quality standard accurately, and because steady quality, side reaction and irritated rate are lower in the use, quality safety.
Compositions with antibacterial action of the present invention, can be through conventional method, get cefmetazole acid and sodium citrate in proportion and prepare the antibacterials of injection dosage form, perhaps get the medicine that cefmetazole acid and sodium citrate prepare the injectable powder dosage form in proportion.
When the compositions that the present invention is made up of cefmetazole acid and sodium citrate is made the injectable powder dosage form, its technical scheme is: in aseptic batch plant, take by weighing cefmetazole acid and sodium citrate sterile bulk drug according to the prescription ratio, pour in the efficient three-dimensional motion mixer, setting the three-dimensional rotating speed that mixes the powder machine is 5 to 8 rev/mins, begins to mix the powder operation according to mixed powder packaging standard rule of operation, mix 60min~90min, behind the mix homogeneously, discharging divides packing promptly.
Beneficial effect: the compositions with antibacterial action provided by the invention is compared with prior art and is had the following advantages:
1, the compositions with antibacterial action provided by the invention, screen through lot of experiments, with cefmetazole acid and sodium citrate combination, the two is coordinated mutually, mutually promote, sodium citrate can effectively increase the water solublity of cefmetazole acid as the cosolvent of cefmetazole acid, shortcoming, the especially cefmetazole acid and the sodium citrate that solve the clinical use inconvenience of sodium citrate have excellent water solublity when weight ratio is combination in 1: 0.65.
2, the compositions with antibacterial action provided by the invention, the two scientific matching of cefmetazole acid and sodium citrate, cefmetazole acid can its antibacterial action of fine performance, the compositions that obtains after the two proportioning has good stability, the injectable powder that makes can long term storage, antibacterial activity composition cefmetazole acid Stability Analysis of Structures, can not produce the impurity of toxic and side effects, stable curative effect safety.
3, the compositions with antibacterial action provided by the invention can make things convenient for and make injection or injectable powder according to a conventional method, the convenient storage and use.
The specific embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, should understand these embodiment only is used to the present invention is described and is not used in and limit the scope of the invention, after having read the present invention, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment 1
By cefmetazole acid and sodium citrate preparation of compositions injectable powder: in aseptic batch plant, mix proportion scheme according to table 1 takes by weighing cefmetazole acid and the common 50kg of sodium citrate sterile bulk drug, pour in the efficient three-dimensional motion mixer, setting the three-dimensional rotating speed that mixes the powder machine is 5 rev/mins, begin to mix the powder operation according to mixed powder packaging standard rule of operation, mix 60min~90min to mix homogeneously, discharging, divide packing, obtain injectable powder.
Get the pH value of each sample of sample detection of each proportioning, be prepared into conventional instillation of human body with water for injection then and use the liquid medicine of concentration, detect the water solublity of each sample solution, concrete experimental result is as shown in table 1.
The pH value of the cefmetazole acid of the different proportionings of table 1 and sodium citrate compositions and water solublity testing result
