  • Publication number: 20240108639
    Abstract: The present disclosure provides methods of preparing pharmaceutical compositions containing cocrystals through the combination application of dielectric heating and distributive and dispersive mixing such as hot melt extrusion (HME). The cocrystals used in these compositions may be formed using an active pharmaceutical ingredient and a co-former. The co-former may be either an excipient or a second active pharmaceutical ingredient. These pharmaceutical compositions may be used in the treatment of a disease or disorder.

  • Publication number: 20230218533
    Abstract: The present disclosure provides pharmaceutical compositions prepared using an additive manufacturing process where the active pharmaceutical ingredient has been rendered into the amorphous form or prepared as an amorphous solid dispersion at a temperature below the melting point of the active pharmaceutical ingredient or the glass transition of the physical mixture or composition of the individual components. The present disclosure also provides methods of preparing these compositions by using properties such as the chamber and surface temperature and the electron laser density.

  • Patent number: 11246833
    Abstract: A method of producing an extruded, powdered/granulated composition comprising an active pharmaceutical ingredient (API), by the steps of providing an API and a porous inorganic excipient, and processing them by an extrusion process to directly produce an extruded, powdered/granulated composition wherein the API is at least partially absorbed within the pores of the inorganic excipient. In preferred embodiments, the API is melted, or solubilised in a solubilizer.

  • Patent number: 10881616
    Abstract: The invention relates to a process of preparing a salt of an active pharmaceutical ingredient, the process comprising providing a blend of an active pharmaceutical ingredient and a salt forming substance, mixing the blend, optionally in the presence of added water, to react the active pharmaceutical ingredient with the salt forming substance to provide the salt of the active pharmaceutical ingredient; wherein when the active pharmaceutical ingredient is acidic, the salt forming substance is a base and the pKa difference between the acidic active pharmaceutical ingredient and the base is greater than 1, typically greater than 2 or preferably greater than 3; or when the active pharmaceutical ingredient is basic, the salt forming substance is an acid and the pKa difference between the basic active pharmaceutical ingredient and the acid is greater than 1, typically greater than 2 or preferably greater than 3.
