Expulsion of material from a delivery device |
| abstract |
A delivery device for delivering an active substance (12) to a patient at a predetermined time after administration comprises a male hydrogel plug (2) engaged in the neck (4) of a female body (6). An expandible excipient (10) such as a hydrogel powder or a pharmaceutical disintegrant in powder, slug or tablet form is provided beneath the active substance. In contact with an aqueous medium, the excipient absorbs water and swells such as to rapidly expel the active substance and effectively deliver it from the device. |
