The present invention pertains generally to the field of therapeutic compounds. The pharmaceutical compositions comprising an effective amount of compounds of formula I, and methods for the treatment of autonomic and other neurological disorders may be formulated for oral, buccal, rectal, topical, transdermal, transmucosal, intravenous, parenteral administration, syrup, or injection. This structure allows the formation of a relatively a thick channel region and decreases the sensitivity of characteristics of the device dependent upon the thickness of the channel region. Since the electric terminal is left outside the BGA, it is possible to easily connect a probe of an inspection apparatus such as an oscilloscope, a voltammeter and a logic analyzer to the electric terminal. The present invention further provides a pharmaceutical dosage form containing an active ingredient, and the compacted pharmaceutical composition.
