| titleOfInvention | Osmotic drug delivery devices with hydrophobic wall materials |
| abstract | Osmotically driven drug delivery devices with walls of porous hydrophobic materi-al as the sole diffusion-limiting wall component are disclosed. Despite pores which are considerably larger than the molecular dimensions of non-volatile species in the interior of the device, despite pores which by their hydrophobic character do not permit the pas-sage of liquid water, and despite the absence of a cellulosic semipermeable membrane, the devices absorb water by osmosis without loss of the non-volatile species, and function in a manner analogous to osmotic pumps of the prior art. By permitting the use of hydrophob-ic substances as the wall material, the invention permits the device to be constructed en-tirely from biodegradable materials. |
