The present invention includes compositions and methods for reduce the taste of the drug in the drug resin complex. The composition may include one or more drug-resin complexes and a highly compressible, free-flowing pharmaceutical excipient. The resin is present in an amount effective to reduce the taste of the drug in the drug resin complex relative to an otherwise identical pharmaceutical composition without the resin; and wherein the highly compressible, free-flowing pharmaceutical excipient causes release of the drug-resin complex in the mouth.

The invention provides a preparation method of dendrobium nobile polysaccharide extracts, which is realized by steps of degreasing, extracting, alcohol precipitating, protein removing, monose and oligosaccharide removing and purifying gel columns and the like. The polysaccharide content in the polysaccharide extract is more than 93 percent. The polysaccharide extract has remarkable oxidation prevention activity, can be combined with medicament excipients and carriers permitted by preparation agents, and can be applied in preparing medicaments or medicament combinations for treating and preventing cardiovascular diseases. The preparation method of the dendrobium nobile polysaccharide extracts is reasonable in design and convenient in operation.

Disclosed is a substantially anhydrous, powdered, galactomannan composition consisting essentially of a galactomannan hydrocolloid exhibiting about 50% to about 90% by weight of anhydromannose residues and about 10% to about 50% by weight anhydrogalactose residues; less than about 1% by weight of protein material and less than about 3% of other nonaqueous impurities. This material is useful for preparing pharmaceutical compositions both in the substantially anhydrous form but preferably in an anhydrated form which includes about 5-15% by weight water. The pharmaceutical compositions comprise a therapeutically effective amount of a drug, the hydrated powered gallactomannan composition and optionally other pharmaceutically-acceptable excipients. When the hydrated powdered purified glactomannan of the invention is used to form a tablet, one sees improved hardness in the tablet formed. The pharmaceutical composition of the invention is particularly valuable for delivering a therapeutically effective drug to the colon without significant release of the drug in the upper GI tract after oral administration of the composition. Unique means to prepare the purified galactomannan in large quantities is provided.

The invention relates to a PLA/PLGA shell-core microsphere prepared by solid-in-oil-in-water in the technical field of pharmacy and a preparation method thereof. The microsphere comprises 0.01 to 50 percent of medicine, 20 to 99.99 percent of polylactic acid and/or polylactic acid-glycolic acid, or/and 0 to 30 percent of pharmaceutical excipient (weight percentage). The method comprises the steps of: adding medicine particles into a PLA and/or PLGA organic solution to be emulsified, then selecting a hydrophilic organic solvent to re-emulsify to form unhardened balls, finally hardening in another large oil phase, removing the organic solvent and collecting micropheres. The method overcomes the disadvantages of low envelope rate of the prior W/O and W/O/W, serious burst release of S/O/O, and environmental pollution, controls the grain diameter of the microsphere according to the need, does not pollute the environment, and can be applied to the preparation of slow release or controlled release microspheres of various medicines and adjuvants of vaccines.

A rapidly disintegrating tablet for oral administration of acid-labile active ingredients is described. The rapidly disintegrating tablet for oral administration of an acid-labile active ingredient comprises a plurality of individual active ingredient units together with pharmaceutical excipients, where the acid-labile active ingredient is present in the individual active ingredient units in a matrix composed of a mixture comprising at least one solid paraffin and one or more substances from the group of fatty alcohol, triglyceride and fatty acid ester, and where excipients which, on oral intake of the tablet, bring about rapid disintegration of the tablet are present.

The present invention describes the use of pharmaceutical compounds in pharmaceutical compositions for sublingual administration, including as active ingredient thereof, an agonist of the central receptor of benzodiazepinics chosen among diazepam, lorazepam, bromazepam, triazolam, alprazolam, flunitrazepam, nitrazepam and midazolam maleate, in a mixture with a pharmaceutical excipient consisting of, at least, 70% of the weight of the final formulation containing 40-45% by weight of lactose, 15-27% by weight of sorbitol and 12-16% by weight of cellulose.

Disclosed are improved pharmaceutical formulations comprising dehydroepiandrosterone (DHEA), enriched in selected polymorphic forms, for therapeutic applications. In one embodiment, the formulation comprises, in solid form, DHEA, at least 85% of which is present as a single polymorph selected from the form I polymorph or the form II polymorph, and at least one pharmaceutical excipient. Methods for making and using such compositions are also disclosed.

The invention discloses a panax notoginseng polysaccharide extract and a preparation method, preparations and applications thereof. The panax notoginseng polysaccharide extract is prepared by taking waste residues produced after panax notoginseng saponins are extracted as raw materials through the steps of extraction, concentration, purification, drying, crushing and detection, wherein the content of panax notoginseng polysaccharides is not less than 15%. The preparation method of the panax notoginseng polysaccharide extract comprises the steps of extraction, concentration, purification, drying, crushing and detection, and specifically comprises the steps of adding waste residues produced after panax notoginseng saponins are extracted into purified water for extracting, carrying out filtration and concentration on the obtained object, adding ethanol into the obtained object for precipitating, and carrying out filtration, purification and drying on the obtained product so as to obtain a target dried product. Pharmaceutical excipients are added into the panax notoginseng polysaccharide extract to be prepared into powder, capsules, granules, tablets or pills; and the panax notoginseng polysaccharide extract is applied to the preparation of antineoplastic drugs and immunity enhancing drugs. According to the invention, waste residues produced after panax notoginseng saponins are extracted are reused, thereby changing waste material into things of value, facilitating the comprehensive utilization of panax notoginseng resources, reducing the cost and improving the economic benefits.

Stabilized substituted benzimidazole modified release pharmaceutical formulations with at least two drug-containing fractions, wherein the release from a first fraction precedes the release from a second fraction, pharmaceutical excipients, processes for preparing the stable formulations, packaging therefor, and their use in treatment of erosive esophagitis and heartburn associated with non-erosive gastroesophageal reflux disease.
