    摘要: An osmotic solid pharmaceutical formulation for the controlled diffusional and osmotic delivery of a therapeutic agent to an environment of use comprising:
    a core comprising a physical mixture of a sulfoalkyl ether cyclodextrin, a therapeutic agent and a pharmaceutically acceptable carrier; and
    a membrane surrounding said core and comprising a film forming agent and a pore forming agent, said membrane having a passageway therethrough for communicating said core to an environment of use;
    wherein,
    a first portion of said therapeutic agent diffuses through said membrane and a second portion of said therapeutic agent passes through said passageway; and
    a major portion of said therapeutic agent is not complexed with said sulfoalkyl ether cyclodextrin.

    摘要: A multi-layered combined rapid and controlled release solid pharmaceutical formulation comprising:
    at least one controlled release first layer comprising a physical mixture of a first therapeutic agent, a release rate modifier and a sulfoalkyl ether cyclodextrin for releasing said first therapeutic agent at a controlled rate into a first environment of use; and
    at least one rapid release second layer comprising a physical mixture of a second therapeutic agent and a sulfoalkyl ether cyclodextrin for releasing said second therapeutic agent rapidly into a second environment of use;
    wherein,
    said first and second layers are juxtaposed; and
    major portions of each of said first and second therapeutic agents are not complexed with said sulfoalkyl ether cyclodextrin.
