摘要:
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.

The present invention especially relates to the use of a combination comprising(1) an ACEI selected from the group consisting of benazepril, benazeprilat, and pharmaceutically acceptable salts thereof, and (2) amlodipine or pharmaceutically acceptable salt thereof, for the manufacture a medicament for the treatment or prevention or delay of progression of a condition selected from the group consisting of hypertension, congestive heart failure, angina, myocardial infarction, artherosclerosis, diabetic nephropathy, diabetic cardiac myopathy, renal insufficiency, peripheral vascular disease, left ventricular hypertrophy, cognitive dysfunction, blood pressure-related cerebrovasular disease, stroke, pulmonary disease or pulmonary hypertension and headache; wherein (i) the amount of amlodipine or a pharmaceutically acceptable salt thereof corresponds to 6 about mg to 40 about mg of the free base and (ii) the amount of the ACE inhibitor or a pharmaceutically thereof corresponds to 20 about mg to 160 about mg of benazepril hydrochloride.
摘要:
Therapeutically active sustained release dosage forms are described which are prepared from compositions which comprise (A) a hydrophilic cellulose ether polymer or mixtures thereof as a binder matrix material, (B) a granulating medium selected from the group consisting of a lipid component, polyethylene glycol polymers, and mixtures thereof, said granulating medium having a melting range higher than about 30.degree. C., and (C) a therapeutically active medicament, said components being in melt association. The compositions are prepared by a melt granulation process.
摘要:
Solid pharmaceutical compositions and methods of their use suitable for the oral delivery of pharmacologically active agents, e.g. peptides, comprising a therapeutically-effective amount of a pharmacologically active agent; a crospovidone or povidone; and a delivery agent for said pharmacologically active agent are disclosed. The compositions utilize micronized forms of the delivery agent which provides enhanced bioavailability of pharmacologically active agents, particularly calcitonin.

摘要:
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.
摘要:
Polyethylene oxide polymer is employed as a directly compressible binder matrix for therapeutically active dosage forms. Advantageously, the polyethylene oxide has an adjustable rate control effect on the release of medicament from the dosage form, enabling in particular the preparation of sustained release dosage forms.
摘要:
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.
摘要:
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.
