Colloid bismuth pectin compound and quality control method of pharmaceutical compositions thereof

The invention relates to a colloid bismuth pectin compound and a quality control method of pharmaceutical compositions of the colloid bismuth pectin compound, and specifically provides a colloid bismuth pectin compound, new quality control indexes of pharmaceutical compositions of the colloid bismuth pectin compound and a detection method of the colloid bismuth pectin compound and the pharmaceutical compositions of the colloid bismuth. In the prior art, the quality of products having poor efficacy can not be well controlled because the efficacy-related indexes are not controlled strictly in the existing quality control methods of colloid bismuth pectin and pharmaceuticals thereof. Based on the existing quality control methods of colloid bismuth pectin and pharmaceuticals thereof, the following detection items and indexes are added: intrinsic viscosity, gel property, uniformity and galacturonic acid content. The invention can effectively ensure clinical efficacy of products, make the product quality standards more scientific, reasonable and controllable, and has great significance in quality control of the colloid bismuth pectin and the pharmaceutical preparation of colloid bismuth pectin.

Method for detecting free bismuth in colloidal bismuth pectin or preparation containing colloidal bismuth pectin

The invention provides a method for detecting free bismuth in colloidal bismuth pectin or a preparation containing colloidal bismuth pectin. The method includes the following steps of: placing colloidal bismuth pectin or the preparation containing colloidal bismuth pectin in a plastic centrifuge tube, adding water to shake for no more than 1min, obtaining a colloidal solution with uniform dissolution, centrifuging the colloidal solution immediately, separating the supernatant, measuring the content of bismuth in the supernatant by complexometric titration or ultraviolet spectrophotometry, andcalculating the content of free bismuth in colloidal bismuth pectin or the preparation containing colloidal bismuth pectin. The method for detecting free bismuth in colloidal bismuth pectin or the preparation containing colloidal bismuth pectin, established by the invention, has the advantages of strong specificity, high accuracy, good repeatability, good linear relationship and high sensitivity,and can be used as a mass control method for free bismuth in colloidal bismuth pectin or the preparation containing colloidal bismuth pectin to effectively control the quality of products of colloidalbismuth pectin or the preparation thereof.

Streptococcus lactis enteric-coated tablets inhibiting helicobacter pylori (HP) and preparation method thereof

The invention provides streptococcus lactis enteric-coated tablets inhibiting helicobacter pylori (HP) and a preparation method thereof. The streptococcus lactis enteric-coated tablets are prepared from streptococcus lactis, colloidal bismuth pectin, furazolidone, spirulina, vitamin U, soybean lecithin, diethyl phthalate, polyacrylic acid resin No. 2, Tween-80, castor oil, polyethylene glycol-6000, xanthan gum, talc and starch. According to a formula, the streptococcus lactis is used as a main active ingredient for treating the helicobacter pylori; the spirulina is suitable for mucosa repair,regeneration and normal secretion of intestinal ulceration formed by helicobacter pylori pathogens; the soybean lecithin has the effects of nourishing the stomach, sterilizing and repairing gastric mucosae; the colloidal bismuth pectin has the effects of isolating gastric acid, protecting injured mucosae and killing the helicobacter pylori. The streptococcus lactis enteric-coated tablets providedby the invention achieves significant inhibiting and infiltrating effects for the treatment of the helicobacter pylori; meanwhile, the mucosal injury and ulceration of the gastrointestinal tract caused by the helicobacter pylori can be alleviated and repaired.

Method for measuring free bismuth in colloidal bismuth pectin or preparation containing colloidal bismuth pectin

The invention provides a method for measuring free bismuth in colloidal bismuth pectin or a preparation containing colloidal bismuth pectin. The method comprises the following steps of: adding ethanolwater solution with the volume concentration of 7-20% into the colloidal bismuth pectin or the preparation containing the colloidal bismuth pectin, and shaking to enable the dissolution to be uniform, or adding ethanol water solution with the volume concentration not more than 5% to shake and disperse, then adding ethanol until the volume concentration of the ethanol in the dispersion liquid is 30-50%, and shaking to enable the dissolution to be uniform to obtain colloidal solution; centrifuging to obtain supernatant; measuring by a complexometric titration method or an ultraviolet spectrophotometry method; and calculating the content of free bismuth in the colloidal bismuth pectin or the preparation containing the colloidal bismuth pectin. The ethanol aqueous solution not only has bettersolubility to free bismuth, but also can seal colloidal bismuth pectin molecules to a certain extent, and effectively prevent the dynamic bismuth salt release process of the colloidal bismuth pectin.According to the invention, the free bismuth is measured by dispersing the colloidal bismuth pectin with the ethanol aqueous solution, and the measuring result of the free bismuth is more accurate and reliable.
