Provided are pharmaceutical compositions and methods for preparing pharmaceutical compositions using solventless mixing methods. Excess coating material that is not bound to a coated API particle may be removed by a sieving process. Coating and dosing ratios can also be optimized to minimize the amount of excess unbound coating material. Specifically, a coating ratio and/or a dosing ratio can be used to minimize the residual amount of excess unbound coating material to minimize agglomeration of coating material during storage. In some embodiments, a pharmaceutical composition is provided, the pharmaceutical composition comprising: 65-85% w/w API particles; 15-30% w/w coating material coating the API particles; and 3-15% w/w matrix surrounding the coated API particles, wherein the pharmaceutical composition comprises a disintegration time rate of less than 10 seconds for at least six months under storage conditions of at least 25° C. and at least 60% relative humidity.

Minimizing agglomeration of drug particle coating material during storage to stabilize disintegration times of pharmaceutical products

Provided are methods of making a pharmaceutical composition comprising: providing a matrix solution/suspension comprising a matrix former, a structure former, 0.1-1.5 wt. % anti-aerating agent, and a solvent; mixing a plurality of hydrophobic particles into the matrix solution/suspension to form a pharmaceutical suspension; and dosing the pharmaceutical suspension into preformed blister packs, wherein a dosed weight of the dosed pharmaceutical suspension is within 10 % of a target dosed weight.

Minimizing aeration of suspensions during in-line mixing

Provided are pharmaceutical compositions and methods for preparing pharmaceutical compositions comprising coated API. Excess coating material that is not bound to coated API may be removed by a sieving process. Coating and dosing ratios can also be optimized to minimize the amount of excess unbound coating material. Additionally, the compositions can be formulated to preserve the functional coating of coated API and to minimize aeration of API when mixed into suspension.

Pharmaceutical compositions comprising coated API

Provided are pharmaceutical compositions and methods for preparing pharmaceutical compositions that preserve the coating of coated API particles in a pharmaceutical suspension. Pharmaceutical compositions include coated active pharmaceutical ingredient (API) particles comprising: an API particle; a first coating comprising one or more deformed components coating the API particle; a second coating comprising silica surrounding and/or partially or fully embedded into the first coating, a matrix former, and a structure former.

Preserving functionally-coated API particles produced by solventless mixing processes in aqueous suspension

Provided are pharmaceutical compositions and methods for preparing pharmaceutical compositions comprising Ibuprofen using solventless mixing methods. Excess coating material that is not bound to coated Ibuprofen may be removed by a sieving process. Coating and dosing ratios can also be optimized to minimize the amount of excess unbound coating material. Additionally, the compositions can be formulated to preserve the functional coating of coated Ibuprofen and to minimize aeration of Ibuprofen when mixed into suspension.
