(a) a matrix having distributed therein as the drug said volatile active ingredient or a physiologically acceptable salt thereof, the matrix comprising a pressure-sensitive adhesive,
(b) an element of a pressure-sensitive adhesive composition which--where (a) contains a salt--contains basic groups to liberate the free base from its salt,
(c) a backing layer impermeable to the diffusable ingredients of (a) and (b), and
(d) a release liner impermeable to the diffusable ingredients of (a) and (b),
matrix (a) or at least a part of (b), whichever is in contact with release liner (d), having a tack sufficient for affixing the patch to the skin, any part of (b) positioned between matrix (a) and release liner (d) being permeable for the deprenyl or the salt thereof or both.
