Devices and methods for treating a diseased tracheobronchial region in a mammal. The device can be a stent which can include a sustained-release material such as a polymer matrix with a treatment agent. The stent can be bioabsorbable and a treatment agent can be incorporated therewith. A treatment method can be delivery of a stent to a tracheobronchial region by a delivery device such as a catheter assembly.

The invention relates to an oral tablet and a preparation method thereof.
