Multi-layered osmotic device |
| abstract |
The present invention provides a simple and improved multi-layered osmotic device ( 1 ) that is capable of delivering a first active agent in an outer lamina ( 2 ) to one environment of use and a second active agent in the core ( 5 ) to another environment of use. Particular embodiments of the invention provide osmotic devices in which the first and second active agents are similar or dissimilar. An erodible polymer coat ( 3 ) between an internal semipermeable membrane ( 4 ) and a second active agent-containing external coat ( 2 ) comprises poly(vinylpyrrolidone)-(vinyl acetate) copolymer. This particular erodible polymer results in an improved multi-layered osmotic device possessing advantages over related devices known in the art. The active agent in the core ( 5 ) is delivered through a pore ( 6 ) containing an erodible plug ( 7 ). The osmotic device ( 1 ) can be coated by a final finish coat ( 8 ). |
