Controlled release pharmaceutical composition with resistance against the influence of ethanol employing a coating comprising neutral vinyl polymers and excipients
The invention relates to a controlled release pharmaceutical composition, comprising a core, comprising a pharmaceutical active ingredient, whereby the core is coated by an ethanol resistance conferring coating layer which has the effect of conferring the release profile of the pharmaceutical active ingredient to be resistant against the influence of ethanol, whereby the ethanol resistance conferring coating layer comprises at least 70% by weight of a mixture of a polymeric portion a) and an excipients portion b), with the polymeric portion a) is consisting of a water insoluble essentially neutral vinyl polymer or vinyl copolymer and the excipients portion b) is consisting of the excipients b1) 100 to 250% by weight of a non-porous inert lubricant, b2) 1 to 35% by weight of a cellulosic compound, b3) 0.1 to 25% by weight of an emulsifier and additionally or alternatively to b3), b4) 0.1 to 30% by weight of a plasticizer whereby the excipients of the excipients portion b) are each calculated on the dry weight of the polymer portion a).
Administration of growth factors for the treatment of CNS disorders
A method and system that is directed to the local delivery of growth factors to the mammalian CNS to treat CNS disorders associated with neuronal death and/or dysfunction is described.
Pharmaceutical dosage form
A pH responsive and mucoadhesive pharmaceutical dosage form for the release of a pharmaceutically active agent is described. The dosage form includes a mucoadhesive layer for site-specific mucoadhesion, a water-insoluble outer layer, and an intermediate layer including one or more pharmaceutically active agents for site-specific delivery. The different membranous layers perform different functions in order to create a drug delivery system which is able to deliver a drug to a specific site, for a particular period of time and with a specific drug release pattern. The dosage form can have two or more intermediate layers, each layer comprising an active agent. The mucoadhesive layer can also include an active agents. The dosage form is preferably an oral or buccal delivery form for release of the active agent into the gastro intestinal tract. The intermediate layer can be an electrospun fibrous membrane layer containing the active agent.
Self-assembled brush block copolymer-nanoparticles for drug delivery
The invention provides amphiphilic liquid crystalline brush block copolymers that can readily self-assemble to nanoparticles in aqueous solutions and also allow for encapsulation of hydrophobic pharmaceutically active molecules.
Stable solid fingolimod dosage forms
The present invention relates to a solid pharmaceutical dosage forms and methods for preparing the solid pharmaceutical dosage form that contains fingolimod or its pharmaceutically acceptable salts, conjugates or complexes thereof. The solid pharmaceutical dosage forms may rapidly disintegrate in a patient's oral cavity.

Delayed-release encapsulation of deer velvet powder to protect the deer velvet powder until micellization and absorption within the terminal illium
An encapsulation of deer velvet powder for ensuring delivery of the deer velvet powder to the terminal ileum of the small intestine, thereby ensuring micellization of unaltered molecules of the deer velvet powder, and systemic delivery of the unaltered molecules to all the organs of the body for regeneration and repair. The encapsulation includes: a delayed release capsule, and deer velvet powder contained within the delayed release capsule. The delayed release capsule is acid resistant, thereby protecting the deer velvet powder from digestive processes while transiting the stomach and upper small intestine, enabling the deer velvet powder to be released substantially along the terminal ilium of the small intestine so as to ensure micellization and absorption of unaltered molecules of deer velvet. Thus, swallowing the deer velvet powder encapsulated in a delayed release capsule delivers more of the benefits of deer velvet than standard encapsulations of deer velvet.
Hydroxyalkyl alkyl cellulose, method for producing the same, and solid preparation
Provided is a hydroxyalkyl alkyl cellulose exhibiting good flowability and high compressibility. More specifically, there are provided a hydroxyalkyl alkyl cellulose having a volume-based average particle size, determined by dry laser diffractometry, of more than 100 m and not more than 150 m; and after dividing all particles into fine particles, spherical particles and fibrous particles by a dynamic image analysis, a volume fraction of the fibrous particles relative to all of the particles of more than 40% and not more than 50%, and a volume fraction of the fine particles relative to all of the particles of less than 2.0%; a solid preparation including the hydroxyalkyl alkyl cellulose; and others.
Gastric reflux resistant dosage forms
Gastric resistant film-forming compositions are described herein. The composition contains a gastric resistant natural polymer, a film-forming natural polymer, and optionally a gelling agent. Suitable gastric resistant natural polymers include polysaccharides such as pectin and pectin-like polymers. The film-forming composition can be used to prepare soft or hard shell gelatin capsules which can encapsulate a liquid or semi-solid fill material or a solid tablet (SOFLET) containing an active agent and one or more pharmaceutically acceptable excipients. Alternatively, the composition can be administered as a liquid with an active agent dissolved or dispersed in the composition. The compositions are not only gastric resistant but may also prevent gastric reflux associated with odor causing liquids, such as fish oil or garlic oil, encapsulated in a unit dosage form and esophageal irritation due to the reflux of irritant drugs delivered orally.
Pulsed extended-pulsed and extended-pulsed pulsed drug delivery systems
The disclosure is directed to drug delivery devices that provide for combinations of extended and pulsed controlled release delivery of active pharmaceutical ingredient(s) APIs. The described drug delivery devices for oral administration of therapeutic compositions can include two or more populations of unit dosage forms including one or more API's in various combinations of pulsed and delayed/extended delivery formulations. The population of unit dosage forms are provided in a variety of different vehicles such as granules, beads, pellets, or tablets and can be contained within a drug delivery device of the present disclosure.
