Terpolymer, wherein 20 to 35% by weight of the structural units are derived from acrylic acid, 45 to 60% by weight of the structural units from a hydrophobic methacrylate selected from a group consisting of isopropyl methacrylate, tert-butyl methacrylate and cyclohexyl methacrylate and 15 to 40% by weight of the structural units from a third olefinic monomer selected from the group consisting of N-vinyl lactam, hydroxy ethyl methacrylate and phenoxyethyl acrylate with the proviso that the total amount of structural units derived from the three monomer groups adds up to 100% by weight, and the use of the terpolymers as crystallization inhibitors in pharmaceutical dosage forms for inhibiting the recrystallization in an aqueous environment of a human or animal body of an active ingredient.

Terpolymers and their use in pharmaceutical dosage forms

The use of powder-form, crosslinked, water-insoluble, low-swelling polyacrylates as disintegrants for solid pharmaceutical dosage forms.
