Embodiment 4 Stability Determinations
,, under 75% condition, place and within 6 months, carry out accelerated stability investigation, in 0,1,2,3,6 sampling and measuring high polymers in 40 DEG C with reference to the sample of example 1, reference example 2 and embodiment 1, embodiment 2.
In amoxicillin, high polymer is measured, and with reference to 2010 editions amoxicillin standards of Chinese Pharmacopoeia, measures according to molecular exclusion chromatography (annex V H).
Chromatographic condition and system suitability: using sephadex G-10(40~120 μ is m) filler, glass column internal diameter 1.0~1.6cm, post height 30~40cm.Taking the 0.05mol/L phosphate buffer [0.05mol/L disodium phosphate soln-0.05 mol/L sodium dihydrogen phosphate (95:5)] of pH8.0 as mobile phase A, taking water as Mobile phase B, flow velocity is 1.5ml per minute, and detection wavelength is 254nm.Taking mobile phase A, B as mobile phase, get 0.1mg/ml blue dextran 2000 solution 200 μ l injection liquid chromatographies respectively, number of theoretical plate calculates and is all not less than 500 by blue dextran 2000 peaks.Tailing factor all should be less than 2.0.In two kinds of flow phase system, the ratio of blue dextran 2000 peak retention times should be between 0.93~1.07, and in contrast solution main peak and need testing solution, in polymer peak and corresponding chromatographic system, the ratio of the retention time at blue dextran 2000 peaks all should be between 0.93~1.07.Take the about 0.2g in amoxicillin and put in 10ml measuring bottle, add 2% Carbon Dioxide sodium solution 4ml and make after dissolving,, shake up to scale with blue dextran 2000 solution dilutions of 0.3mg/ml.Measure 200 μ l injection liquid chromatographies, measure by mobile phase A, record chromatogram.Paddy between the peak height of high polymer and monomer and high polymer is high than being greater than 2.0.Separately, taking Mobile phase B as mobile phase, precision measures contrast solution 200 μ l, continuous sample introduction 5 times, and the relative standard deviation of peak area should be not more than 5.0%.
The preparation of contrast solution: get penicillin reference substance appropriate, accurately weighed, with water dissolution and quantitatively dilution make in every 1ml the approximately solution containing 0.2mg.
Algoscopy: get the about 0.2g of this product, accurately weighed, put in 10ml measuring bottle, add 2% Carbon Dioxide sodium solution 4ml and make to dissolve, be diluted with water to scale, shake up, precision measures 200 μ l injecting chromatographs immediately, measures as mobile phase taking mobile phase A, records chromatogram.Another precision measures contrast solution 200 μ l injecting chromatographs, taking Mobile phase B as mobile phase, is measured in the same method.
Result is as following table:
The above results shows, the contained macromolecule impurity content of amoxicillin granules that the present invention prepares is less than the impurity content in reference example, also be, amoxicillin granules of the present invention has higher quality, better stability, and in preparation process, avoid with an organic solvent, being more suitable for suitability for industrialized production.
