The present invention relates to a tablet composition for oral administration of abiraterone acetate, particularly to pharmaceutical granulates and tablets giving immediate release of abiratetone acetate in the stomach.

An orally disintegrating tablet combinable with a variety of drugs and exhibits excellent disintegrating properties in an oral cavity but having strength and the like allowing ability to form a tablet. The annular orally disintegrating tablet containing a drug and a disintegrating agent; and having a hole in a central portion making it annular. The content of the disintegrating agent relative to total weight is 2% to 50% by weight. It exhibits excellent disintegrating properties, i.e., when a gradient of disintegrating time (seconds) of the tablet with respect to tableting pressure (kN) upon compression-forming is defined as a and a gradient of disintegrating time (seconds) of a disk-shaped orally disintegrating tablet with respect to tableting pressure (kN) upon compression-forming is defined as b, the disk-shaped orally disintegrating tablet having the same weight and external diameter as the annular orally disintegrating tablet the ratio (a/b) is 0.90 or less.

The invention is directed to pharmaceutical compositions such as tablets that exhibit delayed release properties when administered as either whole or half tablets. The invention is also directed to delayed release tablets comprising deferiprone for oral administration, for which twice daily administration is bioequivalent to the same daily dose of an immediate release tablet administered thrice daily. The invention is also directed to methods of making and using the same.

There is provided low-substituted hydroxypropyl cellulose (L-HPC) having good bindability, anti-capping performance and disintegratability. More specifically, there are provided L-HPC having a hydroxypropoxy group content of 5 to 16% by mass and a volume fraction of long fibrous particles of more than 50.0% relative to all of L-HPC particles which are classified, on a basis of dynamic image analysis, into fine particles, spherical particles, the long fibrous particles and short fibrous particles; and a solid preparation containing the L-HPC.

The present disclosure relates to medical devices containing time-release drug substance, and more particularly, to medical tubing, catheters, stents, cables (including fiber optic cables), pills, capsules, sheaths, threads, clamps, sutures, and endotracheal devices. The invention also generally relates to a method for extruding multiple laminated flow streams using microlayer coextrusion to create these various time-release drug delivery products.

There is provide an extended release dosage form comprising a release modifying excipient comprising high amylose starch, cross-linked hydroxypropylated amylopectin, and a pre-gelatinized common starch; wherein the release modifying excipient is substantially free of crosslinks between amylose and amylopectin and substantially free of crosslinks between amylose and amylose. It has been found that the extended release properties of conventional cross-linked high amylose starches (e.g., Contramid) can be reproduced by intimately mixing i) cross-linked chemically modified amylopectin; ii) a high amylose, non-chemically modified starch and; iii) a pre-gelatinized common starch. Producing a release modifying excipient in this way means that no chemical cross linking between (a) amylose and amylopectin or (b) amylose and amylose has occurredproperties heretofore considered vital for Contramid function. The release modifying excipient blends overcome problems associated with use of Contramid, and provide a flexible platform for formulation of active pharmaceutical ingredients for controlled release applications.

An example device includes at least one three-dimensional (3D) printed tablet and a 3D-printed production support structure. Each 3D-printed tablet includes an excipient material and an active ingredient. The 3D-printed support structure includes a 3D-printed planar structure comprising the excipient material and at least one 3D-printed connecting member comprising the excipient material. The planar structure includes at least one aperture, each aperture corresponding to one of the at least one 3D-printed tablet. The connecting member detachably connects the at least one 3D-printed tablet with the 3D-printed planar structure and positions the at least one 3D-printed tablets within the apertures.

A drug delivery device includes a capsule, a logic circuit disposed within the capsule, and an actuator connected to the logic circuit and configured to expose an interior of the capsule to an exterior of the capsule upon activation by the logic circuit.

Disclosed herein are drug delivery devices and methods for the treatment of ocular disorders requiring targeted and controlled administration of a drug to an interior portion of the eye for reduction or prevention of symptoms of the disorder. The devices are capable of controlled release of one or more drugs and may also include structures which allow for treatment of increased intraocular pressure by permitting aqueous humor to flow out of the anterior chamber of the eye through the device.
