摘要：
A modified release benzonatate solid tablet or capsule is described which comprises a benzonatate adsorbate in a matrix with a sufficient amount of one or more pharmaceutically acceptable modified release pH-independent, substances to provide a modified release profile to the benzonatate, wherein there is substantially no benzonatate release from the tablet or capsule in the buccal cavity and no more than about 25% release of the benzonatate within 1 hour as determined in an in vitro dissolution assay.
