Abstract: The present invention provides conjugates comprising a sugar such as mannitol and one or more L-DOPA and/or DOPA decarboxylse inhibitors including, inter alia, L-DOPA, carbidopa, benserazide, or a combination thereof, wherein the sugar is conjugated to the carboxyl group of the L-DOPA and/or DOPA decarboxylse inhibitor/s) via a hydroxyl group of the sugar. The present invention further provides related pharmaceutical compositions and methods of producing the conjugates, as well as methods of use for treating medical disorders responsive to dopamininergic stimulation such as movement disorders including, inter alia, Parkinson's Disease.

Abstract: A method includes using a subcutaneously-implanted pump to deliver to a portion of a gastrointestinal tract a formulation including a levodopa compound and a carbidopa compound which provides a treatment for a neurological disease, such as Parkinson’s disease.

Abstract: A pharmaceutical composition for treatment of Parkinson's disease comprising a compound of levodopa dissolved in a non-degradative solvent which allows transdermal administrtion of levodopa. The compound of levodopa is an alkyl-ester of levodopa and the solvent is a formulation comprising a substantially non-aqueous solvent, a transdermal enchancer and a detergent. The alkyl-ester of levodopa is preferably levodopa-ethyl-ester (LDEE).

Abstract: There is provided a composition for the transdermal application of basic drugs which have a high specific activity. The drug is provided in combination with a fatty acid having a low molecular weight. Amongst others, the delivery system is suited for cholinergic and anticholinergic basic drugs. The compositions can be supported by a pad, bandage or the like. It is one of the advantages of the compositions of the invention that a prolonged effect can be obtained, with an essentially constant therapeutic level of the active ingredient.
