Summary for Patent: 8,574,626
Title:Osmotic device containing amantadine and an osmotic salt
Abstract: The osmotic devices of the present invention contain a unitary core comprising a salt of amantadine and an osmotic salt, wherein the two salts have an ion in common. The release rate of the amantadine is a sigmoidal release. The osmotic device includes a semipermeable membrane having a controlled porosity that can be adapted as needed to cooperate with the osmotic salt in providing a predetermined drug release profile. The osmotic salt need not be coated and it is in admixture with the amantadine salt. The osmotic device further includes a drug-containing coat external to the semipermeable membrane. The osmotic device can include one or more additional drugs in the core and/or the drug-containing coat.
