Strategy and tactic of modern Parkinson therapy

The aim of modern Parkinson therapy is to overcome the dopamine deficit in the brain of parkinsonian patients which is the cause of their motor disability. This can be achieved in two ways: (a) substitution of the lacking dopamine by l-dopa, or (b) stimulation of the endogenous biosynthesis by activating the enzyme tyrosine hydroxylase. The latter approach is possible by the iron compound oxyferriscorbone or by the coenzyme nicotinamide adenine dinucleotide (NADH). In addition to these two major medications the essential therapeutic additives such as the decarboxylase inhibitor benserazide, the monoamineoxidase B inhibitor deprenyl and the dopamine receptor agonist lisuride should be used for the fine adjustment of the individual patient.
