摘要:
The present invention provides a water-soluble effervescent composition prepared by hot-melting (i) an active component and (ii) an acid and a carbonate for effervescing, both in powdery or granular state, with (iii) a water-soluble adjuvant whose melting point is not lower than 40.degree. C., for addition to drinking water.
摘要:
The rate of disintegration and/or dissolution of effervescent acetylsalicylic acid tablets obtained by direct compression of a dry powder mixture is surprisingly increased by incorporating in said mixture powdered dextrose and/or sucrose. Preferably, spray-crystallized dextrose is used.
摘要:
A non-alcoholic effervescent compound for cleaning and disinfecting the mouth, teeth, gums and breath without necessity of alcohol as a solvent. Surface acting agents, or surfactants, are used to reduce surface tension of the compound in solution, facilitating dissolution of all additives including non-soluble oil-containing components. Surface acting agents also produce a foaming effect which loosens bacteria and food off and out from between teeth. The compound eliminates use of alcohol as a solvent, has increased cleaning action from both foaming and effervescence and produces a good-tasting, desirable mouthwash with appropriate flavor concentrations.

A calcium citrate composition having a bulk density greater than about 1.1 g/cc. Citric acid and a calcium compound are mixed to produce a mixture having a calcium compound/citric acid molar ratio of about 1.5. A hydrated mixture percent is produced by agitatively adding water to the mixture, although when desired the calcium compound, citric acid and water mayBACKGROUND OF THE INVENTIONA portion of the development of the present invention was supported by Grant No. P01-AM 20543 from the United States Government, National Institutes of Health.
摘要:
A method and composition for providing aspartame as a sweetener in effervescent calcium ion-generating systems is provided. The method includes a step for providing a selected surfactant in association with the aspartame sweetener, to provide for aqueous solution of the aspartame in the presence of the solubilized calcium without film formation and without excessive foaming. Preferably, the aspartame/surfactant is provided by a granule composition, utilized in association with a calcium carbonate/citric acid effervescent couple.
摘要:
A pharmaceutical preparation containing ibuprofen is disclosed. In the preparation, the ibuprofen particles are enveloped by a coating of a hydro-colloid and fumaric acid. Preferably, the hydro-colloid comprises xanthan gum and/or maltodextrin. This preparation reduces the tendency of ibuprofen to irritate the esophagus and the gastrointestinal tract when taken orally. An effervescent mixture of the ibuprofen containing preparation can be prepared by incorporating citric acid and calcium carbonate into the mixture. A process for the manufacture of the ibuprofen containing preparation is also disclosed. In this process, ibuprofen particles are coated with the hydro-colloid and fumaric acid under vacuum conditions in a vacuum mixing machine and the resulting preparation is thereafter vacuum-dried.
摘要:
Dry, stable carbonating agents comprised of a carbohydrate/metal bicarbonate complex are disclosed. The complex is prepared by reacting a carbohydrate with a metal hydroxide or oxide at a temperature not exceeding 25.degree. C. to form a carbohydrate/metal hydroxide adduct to which carbon dioxide is then introduced to form the complex. The complex is then immediately dried, preferably by freeze drying. The carbonating agents are particularly useful as components of dehydrated beverage powders. Upon rehydration, the complex releases carbon dioxide and carbonates the beverage. Additionally, upon rehydration the complex promotes the solubilization of the carbohydrate components in the beverage.
摘要:
Flavored, effervescent, water soluble compositions containing water-soluble and oil-soluble vitamins and amino acid chelated minerals in bioavailable form are contained in a composition consisting of 20-30% of a vitamin blend consisting of water-soluble and oil-soluble vitamins adsorbed on a lactose carrier containing a minor amount of propylene glycol, 5-25% of one or more amino acid chelated minerals selected from the group consisting of calcium, magnesium, iron, zinc, copper and manganese, 20-45% citric acid, 5-25% of one or more alkali or alkaline earth metal bicarbonates or carbonates, 1-5% flavoring agent, 0.5-2% of a sweetening agent and sufficient additional lactose carrier to provide the desired vitamin and mineral content per unit dosage which will normally vary between about 2 and 6 grams. When dissolved in water a flavored, lightly carbonated drink is provided which will contain in soluble bioavailable form between about 50 to 100% of the U.S. RDA of one or more vitamins contained in a dosage unit of the composition and between about 20 to 50% of the U.S. RDA of one or more of the trace minerals iron, zinc, copper and magnesium as contained in a unit dosage of the composition as amino acid chelates. Separate effervescent vitamin compositions without minerals and mineral compositions without vitamins are also disclosed.
摘要:
A tablet for oral adminstration of a sustained-release medication is formed by compressing microcapsules of the active principle. The microcapsules are of a size range between about 5 and 300 microns and comprise particles of active principle coated with a thin, flexible layer of sustained release material. The sustained-release material contains about 15-30% by weight thereof of plasticizer and is coated in an amount corresponding to 10-25% of the weight of the active material. Excipients causing disintegration of the tablet after administration can be uniformly mixed with the microcapsules prior to compression.
