A membrane or matrix for controlling the permeation rate of drugs |
| abstract |
The invention relates to a membrane or matrix for controlling the permeation rate of a drug, wherein said membrane or matrix comprises a siloxane-based elastomer composition which comprises at least one elastomer and possibly a non-crosslinked polymer. The elastomer composition comprises poly(alkylene oxide) groups, and the poly(alkylene oxide) groups are present in the elastomer or the polymer as alkoxy-terminated grafts of polysiloxane units, or as blocks, the said grafts or blocks being linked to the polysiloxane units by silicon-carbon bonds, or as a mixture of these forms. The invention also relates to methods for the preparation of the elastomer composition to be used in said membrane or matrix. |
