摘要:
A medicament carrier composition includes a medicament and a polymer component including a polyvinylpyrrolidone having a weight average molecular weight of at least 700,000 g/mol. The medicament carrier composition has a viscosity of from 500 to 5,000 cps at 250 C, is substantially free of cellulose, and includes an auxiliary polymer. The medicament carrier composition is used to form a film that is also substantially free of cellulose. The film has a consistent thickness and size, and an increased flexibility and increased moisture resistance due to the polyvinylpyrrolidone. The medicament carrier composition is also used in a method of forming the film. The method includes the steps of providing the medicament and the polymer component. The method also includes the step of combining the polymer component and the medicament to form the medicament carrier composition. The method further includes the step of drying the medicament carrier composition to form the film.
