METHOD OF PRODUCING TABLETS OF N-BENZYL-N-METHYL-1-PHENYLPYRROLO[1,2-a]PYRAZINE-3-CARBOXAMIDE Russian patent published in 2024 - IPC A61K9/20 A61K31/4985 A61K47/38 A61K47/22 A61P25/22 

FIELD: medicine; pharmaceutics.

SUBSTANCE: invention relates to a method of producing tablets containing N-benzyl-N-methyl-1-phenylpyrrolo[1,2-α]pyrazine-3-carboxamide as an active substance, as well as excipients acceptable in pharmaceutical technology. Method of producing the tabletted form of N-benzyl-N-methyl-1-phenylpyrrolo[1,2-α]pyrazine-3-carboxamide is characterized by the fact that it has improved release in purified water (more than 80%) and 3% sodium lauryl solution ( more than 90%). Examples also show that tablets of N-benzyl-N-methyl-1-phenylpyrrolo[1,2-α]pyrazine-3-carboxamide, obtained using the methods described in this patent, are characterized by a reproducible result for the "Dissolution" test compared to by the method proposed earlier.

EFFECT: disclosed in this patent methods of producing tablets based on N-benzyl-N-methyl-1-phenylpyrrolo[1,2-α]pyrazine-3-carboxamide excludes the step of preparing a binder solution from the production process and thereby simplifying the technology of producing the finished dosage form; also new methods of obtaining are safe from the point of view of toxicology and fire hazard, since the possibility of using organic solvents in the process of producing tablets of N-benzyl-N-methyl-1-phenylpyrrolo[1,2-α]pyrazine-3-carboxamide is excluded.
