For purposes of the following detailed description, it is to be understood that embodiments provided by the present disclosure may assume various alternative variations and step sequences, except where expressly specified to the contrary. Moreover, other than in any operating examples, or where otherwise indicated, all numbers expressing, for example, quantities of ingredients used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.
Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard variation found in their respective testing measurements.
Also, it should be understood that any numerical range recited herein is intended to include all sub-ranges subsumed therein. For example, a range of “1 to 10” is intended to include all sub-ranges between (and including) the recited minimum value of 1 and the recited maximum value of 10, that is, having a minimum value equal to or greater than 1 and a maximum value of equal to or less than 10.

An immediate release composition or formulation can release substantially all of a pharmaceutically active ingredient into the gastrointestinal tract of a patient within less than 1 hour following oral administration, such as within less than 50 minutes, within less than 40 minutes, within less than 30 minutes, within less than 20 minutes, or within less than 10 minutes following oral administration. For example, an immediate release dosage form can release greater than 90%, greater than 95%, or greater than 98% of the constituents of the pharmaceutical composition into the gastrointestinal tract within less than 1 hour, such as within less than 50 minutes, less than 40 minutes, less than 30 minutes, less than 20 minutes, or less than 10 minutes, following oral administration. Immediate release pharmaceutical compositions can be useful for administering pharmaceutically active ingredients that are absorbed into the systemic circulation from the upper portion of the gastrointestinal tract.
“Modified release” pharmaceutical compositions and formulations can include controlled release formulations, delayed release formulations, extended-release formulations, sustained release formulations, timed release formulations, pulsatile release formulations, and pH-dependent release formulations. These formulations are intended to release a pharmaceutically active ingredient from the pharmaceutical composition at a desired rate and/or at a desired time following oral administration by a patient and/or at a certain location or locations within the gastrointestinal tract and/or at a certain pH within the gastrointestinal tract. The United States Pharmacopeia (USP) defines a modified release system as one in which the time course or location of drug release or both, are chosen to accomplish objectives of therapeutic effectiveness or convenience not fulfilled by immediate release dosage forms. A modified release oral dosage form can include extended release and delayed-release components. A delayed release dosage form is one that releases a drug all at once at a time other than promptly after administration. A modified release formulation can include delayed-release using enteric coatings, site-specific or timed release such as for colonic delivery, extended-release including, for example, formulations capable of providing zero-order, first-order, or biphasic release profiles, and programmed release such as pulsatile and delayed extended release.

An excipient granulation was prepared using high-shear dry granulation and high shear wet granulation.
Formulation development work with various excipients was undertaken to identify excipient granule formulations that rapidly formed a viscous solution after being reconstituted with 40 mL of water and were suitable for oral administration.
The methods to produce excipient granules were (1) dry granulation through roller compaction and/or slugging on a tablet press, and (2) high-shear wet granulation using either a small coffee grinder for small scale experiments or on a 4 L bowl high-shear granulator for the larger batch size.
An example of an excipient granule composition is provided in Table 1.
Excipient granules were prepared by dry mixing the constituents and then granulating the dry mixture with a buffer comprising the sodium citrate dihydrate and the citric acid anhydrous dissolved in water to provide a first granulation. The first granulation was wet massed to provide a first wet mass, which was then granulated with water to provide a second granulation. The second granulation was wet massed to provide a second wet mass and dried to provide the excipient granules.
A Collette (GEA) GRAL 25 high shear granulator equipped with a 25 L jacked bowl was used for granulation. The jacketed bowl was coupled to an Advantage Engineering Air cooled water chiller set at 46° F. (8° C.). Buffer or water was sprayed into the mixture using a two fluid nozzle with a 1-mm nozzle orifice at an atomization pressure of 45 bar.
The excipient granules were dried using a Freund-Vector FLM-3 fluid bed drier at 60° C.
The dried excipient granules were milled using a Quadro Comil® 197 equipped with 50 G or 32 G screens and sieved using a tabletop vibratory sieving base equipped with #35 and #70 mesh screens. Fines (<210 μm) passing through the #70 mesh screen were removed.
The excipient granules (1.2 g) were combined and mixed with 40 mL of water to provide a reconstituted viscous solution. The pH of the reconstituted viscous solution was 4.3.
The reconstitution viscosity profile for the excipient granules of Example 1 is shown in
The reconstitution viscosity was determined by combining 1.2 g or the excipient granules in 40 mL of water at a temperature of 23° C. and mixing using a Brookfield Digital Viscometer Model LVDV-I+ equipped with a Brookfield SC4-18 spindle at a spindle speed of 30 rpm.
The reconstitution luminosity profile for the excipient granulation of Example 1 and other excipient granules is shown in
Luminosity was measured by combining and mixing the excipient granules of Example 1 with 40 mL of water at a temperature of 23° C. and determining the viscosity using a Technical Color Solutions Datacolor™ 650 spectrophotometer.
The excipient granules of Example 1 had a bulk density from 0.58 g/mL to 0.62 g/mL, a tapped density from 0.69 g/mL to 0.74 g/mL, a Hausner Ratio from 0.18 to 1.20, a compressibility index from 15.5 to 16.8, and a Flodex value of 4.
It should be noted that there are alternative ways of implementing the embodiments disclosed herein. Accordingly, the present embodiments are to be considered as illustrative and not restrictive. Furthermore, the claims are not to be limited to the details given herein and are entitled their full scope and equivalents thereof.
