103 results about "Sustained release dosage forms" patented technology

The present invention relates to zero-order sustained release solid dosage forms suitable for administration of a wide range of therapeutically active medicaments, especially those that are water-soluble, and to a process of making same. The solid dosage form comprises (a) a matrix core comprising ethylcellulose and the active agent and (b) a hydrophobic polymer coating encasing the entire matrix core.

Chronic pain is alleviated in a mammal suffering there from by administering to the mammal a chronic pain alleviating amount of a nontoxic N-methyl-D-aspartate receptor antagonist such as dextromethorphan, dextrorphan, ketamine or pharmaceutically acceptable salt thereof, in combination with a μ-opiate analgesic such as tramadol or an analogously acting molecular entity, and a capsaicin or an ester of capsaicin, and optionally in sustained release dosage form.

The present invention relates to sustained-release formulations and dosage forms of ruxolitinib, or a pharmaceutically acceptable salt thereof, which are useful in the treatment of Janus kinase-associated diseases such as myeloproliferative disorders.

The present invention relates to oral sustained release formulations of tofacitinib and pharmaceutical acceptable salts thereof. The formulations described herein have desirable pharmacokinetic characteristics.

Corticosteroid microparticle formulations are provided for use for treating pain, including pain caused by inflammatory diseases such as osteoarthritis or rheumatoid arthritis, and for slowing, arresting or reversing structural damage to tissues caused by an inflammatory disease, for example damage to articular and/or peri-articular tissues caused by osteoarthritis or rheumatoid arthritis. Corticosteroid microparticle formulations are administered locally as a sustained release dosage form (with or without an immediate release component) that results in efficacy accompanied by clinically insignificant or no measurable effect on endogenous cortisol production.

The novel sustained release dosage form comprising an active agent and a combination of a non-swelling pH dependent release retardant and a non swelling pH independent release retardant polymer which provides pH-independent drug release for a considerable period of time after administration.

Aspects of the invention include a sustained release dosage form that can be administered to an oral cavity, e.g., the mouth. In certain embodiments, the sustained release dosage form is formulated as a lozenge or gum that may be administered to an oral cavity for the purpose of providing lubrication therein. In certain embodiments, the sustained release dosage form not only provides lubrication to a mucosal surface of an oral cavity, but also provides for the sustained release of a flavoring and/or beneficial agent. Accordingly, in certain embodiments, the sustained release dosage form includes a water-insoluble polymer, e.g., ethylcellulose, an essential oil component, and an effective amount of a film forming binder, e.g., xanthan gum. In certain embodiments, the effective amount of the film forming binder and the type of film forming binder are selected so as to provide the sustained release dosage with the capability of lubricating one or more mucosal surfaces within an oral cavity when the dosage form is positioned therein. In certain embodiments, the sustained release dosage form is formulated in a manner sufficient to form a matrix that includes the various components of the sustained release dosage form, such that when positioned in an oral cavity the matrix slowly dissolves and thereby lubricates the oral cavity and/or delivers a flavoring and/or beneficial agent thereto. Methods of formulating such dosage forms and administering them to an oral cavity for the treatment of an adverse condition are also provided.

A method of treating or preventing myocardial ischemia in a patient in need thereof comprising administration of a controlled-release Galenical preparation of pharmaceutically acceptable Diltiazem including the pharmaceutically acceptable salts thereof, suitable for evening dosing every 24 hours containing from about 180 mg to about 420 mg of the form of Diltiazem associated with excipients to provide controlled (sustained) release of the form of Diltiazem for providing a C_max of Diltiazem in the blood at between about 10 hours and about 17 hours after administration, the preparation comprising the form of Diltiazem in oral sustained-release dosage form in which the Diltiazem is adapted to be released after administration over a prolonged period of time and exhibits when given to humans

(i) a higher bioavailability when given at night compared to when given in the morning without food according to FDA guidelines or criteria and

(ii) bioequivalence when given in the morning with and without food according to the same FDA guidelines or criteria.

A solid dosage form suitable for forming a tablet for the containment and delivery of medicament is provided wherein the matrix forming material is a pressure sensitive adhesive, present in the amount from about 0.1 to about 40 weight %, based on the total weight of the composition. The dosage form is comprised of the medicament and a water-insoluble polymer silicone pressure sensitive adhesive and allows release of the medicament in a controlled fashion depending on simple parameters such as weight percent of the polymer silicone adhesive. A sustained release dosage form is provided for delivery of medicament wherein the release rate of medicament does not depend on the dissolution medium of the pH. Another aspect of invention is formation of solid tablets of poorly compressible material and the method for making the solid composition. The dosage form for this invention s particularly suitable for oral dosage forms.

The present invention provides a modified release dosage form of tacrolimus that releases two or more amount of tacrolimus upon oral administration, the first amount of tacrolimus releases from the immediate release dosage unit substantially immediately within 0-2 hours followed by a time interval ranging from about 1-10 hours during which substantially no amount of tacrolimus is released from the dosage form, after which a second amount of tacrolimus is released wherein said second amount is released from the delayed release dosage unit either immediately e.g. within 0-2 hours or over a period of time ranging from about 2-12 hours from its initial release from the delayed release dosage unit. The dosage form may further comprise additional amount of tacrolimus to provide additional pulse of tacrolimus. The dosage forms of tacrolimus exhibit improved bioavailability and reduced flux or fluctuation over existing composition of tacrolimus. A method of preparing the dosage forms is also described.
