Matrix-assisted cocrystallization (MAC) simultaneous production and formulation of pharmaceutical cocrystals by hot-melt extrusion
Contributor(s):: Boksa, Kevin, Otte, Andrew, Pinal, Rodolfo
A novel method for the simultaneous production and formulation of pharmaceutical cocrystals, matrix-assisted cocrystallization (MAC), is presented. Hot-melt extrusion (HME) is used to create cocrystals by coprocessing the drug and coformer in the presence of a matrix material. Carbamazepine...

Toward Continuous Crystallization of Urea-Barbituric Acid: A Polymorphic Co-Crystal System
Contributor(s):: Powell, KA, Bartolini, GWittering, KE, Saleemi, AN, Wilson, CC, Rielly, CD, Nagy, ZK
Pharmaceutical co-crystals are multicomponent molecular systems typically formed through hydrogen bonding of a co-former molecule with the active pharmaceutical ingredient (API). Just as many single component molecular structures can exhibit polymorphism due to the geometry of hydrogen bond...
