A composite formulation has been developed for selective, high efficacy delivery to specific regions of the mouth and gastrointestinal tract. The formulation is typically in the form of a tablet or capsule, which may include microparticles or beads. The formulation uses bioadhesive and controlled release elements to direct release to specific regions, where the drug is absorbed in enhanced amounts relative to the formulation in the absence of the bioadhesive and / or controlled release elements. This is demonstrated by an example showing delivery of gabapentin with a greater area under the curve (“AUC”) relative to the FDA reference immediate release drug, i.e., the AUC of the composite bioadhesive formulation is greater than 100% of the AUC of the immediate release drug. In the preferred embodiments, the formulation includes drug to be delivered, controlled release elements, and one or more bioadhesive elements. The bioadhesive polymer may be either dispersed in the matrix of the tablet or applied as a direct compressed coating to the solid oral dosage form. The controlled release elements are selected to determine the site of release. The bioadhesive components are selected to provide retention of the formulation at the desired site of uptake and administration. By selecting for both release and retention at a specific site, typically based on time of transit through the gastrointestinal tract, one obtains enhanced efficacy of uptake of the drug. This is particularly useful for drugs with narrow windows of absorption, and drugs with poor solubility such as the BCE class III and class IV drugs.

A liposome-capsule dosage unit system for the delivery of a biologically active material is formed by encapsulating a biologically active materials in liposomes and then placing the liposome encapsulated material into a capsule. The capsule is typically a soft gel capsule or a two piece capsule capable of tolerating a certain amount of water. A less water tolerant capsule can be employed if the liposomes are dehydrated prior to placement within the capsule. Biologically active material include drugs, nutritional supplements, vitamins, minerals, enzymes, hormones, proteins and polypeptides. The system is especially suited for the delivery of materials with poor oral solubility, materials that are not absorbed or are poorly absorbed from the gastrointestinal tract, and materials that have conventionally been given by an invasive route. The system can be administered orally, intra-occularly, intranasally, rectally, or vaginally.

A multiple pulsed dose drug delivery system for pharmaceutically active amphetamine salts, comprising an immediate-release component and an enteric delayed-release component wherein (1) the enteric release coating has a defined minimum thickness and / or (2) there is a protective layer between the pharmaceutically active amphetamine salt and the enteric release coating and / or (3) there is a protective layer over the enteric release coating. The product can be composed of either one of a number of beads in a dosage form, including either capsule, tablet, or sachet method for administering the beads.

A pharmaceutical dosage form such as a capsule, a conventional or orally disintegrating tablet capable of delivering a nitrogen (N)-containing therapeutic agent having a pKa in the range of from about 5 to 14 into the body in a sustained- released fashion, in order to be suitable for a twice- or once-daily dosing regimen, comprises at least one organic acid, which solubilizes the therapeutic agent the drug prior to releasing it into the hostile intestinal environment wherein said weakly basic drug is practically insoluble. The unit dosage form is composed of a multitude of multicoated particulates (i.e., immediate-release beads, sustained- release beads and / or one or more timed, pulsatile-release bead populations) is designed in such a way that said weakly basic drug and said organic acid do not come into close contact during processing and / or storage for in-situ formation of acid addition compounds while ensuring that the acid is not depleted prior to completion of the drug release.

The present invention relates to pharmaceutical compositions of mesalamine. The composition of the invention is a capsule dosage form filled with a tablet. The invention also relates to process for preparing such compositions. The invention specifically relates to a composition comprising an effective amount of mesalamine having higher bulk density.

A dispersing solid (capsule, tablet, particle, suppository and dripping pill) of cyclosporin A is prepared from cyclosporin A and carrier by solvent method, solvent fusion method, etc. It has high solubility of easy absorption.

The invention discloses a Ruyizhenbao medicine composite, which is prepared by adopting the following steps of essential oil extraction and inclusion, ethanol extraction, water extraction, fluid extract drying, medicinal material fine powder crushing, expensive and fine medicine fine powder preparation and the like. Pharmaceutically conventional auxiliary materials are added according to a conventional process to be prepared into clinically acceptable dosage forms such as: powders, capsules, tablets, oral liquid, condensed pills, granular formulations, pills, pellets and slow release preparations. The invention is characterized in that the Ruyizhenbao composite is prepared by taking phytochemical components as the material base and the pharmacodynamics activity as the guidance by adoptinga modern extraction preparation method. The medicinal preparation prepared by the method disclosed by the method has the advantages of high absorption rate, stable pharmacodynamic components, high bioavailability and the like under the condition that the pesticide effects of the raw preparation are remained.

The invention relates to the field of medicine, in particular to a pharmaceutical composition containing butylphthalide and a novel solubilizer to improve the water solubility of butylphthalide by means of the novel solubilizer, clinically required solid form, or semisolid form or liquid form of butylphthalide is developed, so that the treatment effect of butylphthalide can be better realized. The composition can be used for preparing various drug forms such as tablets, capsules, particles, powder, ointment, cream, gel, infusion, squirt cut, powder filling and oral liquid. Compared with the prior art, the pharmaceutical composition is better in safety performance and water solubility of butylphthalide.

An entecavir crystalline compound and a capsule preparation containing the entecavir crystalline compound are provided. The X-ray powder diffraction of the crystalline compound measured by Cu-K alpha1 is shown as Figure 1. The capsule preparation containing the entecavir crystalline compound comprises the components of an entecavir crystalline compound, a solubilizer, a filler, a disintegrating agent, a lubricant and a binder. The entecavir capsule provided by the invention uses pharmaceutical excipients almost with no side effects on the human body, and the in vivo and in vitro experiments show that the entecavir capsule can be released in a short time to achieve therapeutic plasma concentration and maintain therapeutic plasma concentration for a long time.
