  • Publication number: 20210085631
    Abstract: Solid oral dosage forms, especially tablets, of a pharmaceutical composition comprising a supramolecular complex can be formed from a direct compression process or a compaction process such as roller compaction. Such solid oral dosage forms feature an immediate release profile that allows for fast release of the therapeutic agent. A particularly useful supramolecular complex is trisodium [3-((1S,3R)-1-biphenyl-4-ylmethyl-3-ethoxycarbonyl-1-butylcarbamoyl) propionate-(S)-3?-methyl-2?-(pentanoyl{2?-(tetrazol-5-ylate)biphenyl-4?-ylmethyl}amino)butyrate]hemipentahydrate.

  • Publication number: 20100035949
    Abstract: A drug delivery system, e.g., microemulsion preconcentrate, that spontaneously forms a microemulsion when brought in contact with an aqueous medium. The drug delivery system contains valsartan, a hydrophilic component, a lipophilic component and a surfactant. A particularly useful hydrophilic component in the system is a polymer that is solid at room temperature, e.g., solid PEG.

  • Patent number: 4723958
    Abstract: There is provided a novel drug delivery system which provides for intermittent drug delivery with readily adjustable intervals between drug delivery pulses. This is accomplished by providing a multilayer device in which layers of active drug are readily expandable or erodable when contacted with the environment in which the drug is to be administered. The drug layer is alternated with an inert layer and a multiplicity of such layers are contained within a tube impervious to such environment but provided with an opening into such environment. The multiplicity of such layers is driven along the length of such tube towards the opening. The interval between pulses is determined by the rate the layers are driven along the tube and the sizes of the layers. The duration of the pulse is determined by the rate of expansion or dispersion of the active layer into the environment, wherein the rate of expansion or dispersion is greater than the rate the layers are driven along the tube.

  • Patent number: 4690775
    Abstract: Stable, isotropic gels which can be readily redispersed/reconstiuted into fluid emulsions, as such providing useful carriers for a wide variety of substances having little or no solubility in water, e.g., some types of drugs, are prepared by centrifuging an emulsion comprising a substantially oleophilic, hydrophobic liquid component constituting the dispersed phase in a substantially aqueous liquid component containing an emulsifying amount of emulsifying amount of emulsifying agent which is soluble therein at its level of concentration but which is substantially insoluble in the oleophilic, hydrophobic component, the emulsion being devoid of gelling agent, to separate the emulsion into a gel phase containing substantially all of the oleophilic, hydrophobic component of the emulsion and a clear aqueous phase.
