Abstract
A 12-hour anti-tussive modified release solid tablet or tablet-in-capsule is described which comprises a benzonatate-silicon dioxide adsorbate powder in a hydrophilic matrix to provide a 12-hour 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 1% release of the benzonatate within half an hour as determined in an in vitro dissolution assay.
