EXECUTIVE SUMMARY
The worldwide market for Parkinson's disease drugs was $700 million in 1997, accounting for 22% of neurology-related products, and is predicted to reach $1,500 million in 2002. The increase can be attributed to the growing global elderly population and because the Parkinson's disease rate increases with age.


There is an ongoing debate about the use of the current gold standard treatment - levodopa - and whether its use should be delayed in younger patients so as to avoid inevitable movement problems later on in treatment. New alternative treatments are being developed as monotherapies to postpone the need for levodopa treatment and as adjunctive compounds to reduce the dosage of levodopa required, both with the common goal of preventing the 'on-off' fluctuations characteristic of lengthy treatment with levodopa. Other compounds on the market include the dopamine agonists, catechol-O-methyltransferase (COMT) inhibitors and monoamine oxidase inhibitors.


Recent setbacks involving serious side effects with Roche's COMT inhibitor Tasmar (tolcapone), have left scope for improvement in this area, a gap which competitor companies are already attempting to fill. Again, there are opportunities for more convenient drug formulations. This is because the nature of Parkinson's disease means that swallowing an oral formulation can be difficult for some patients and so other options are required.


Alternative strategies are also being employed such as dopamine reuptake inhibitors, glutamate antagonists, adenosine A2 antagonists, iron chelating agents and the use of levodopa prodrugs. More excitingly, although in its early stages, are techniques which could revolutionise the way Parkinson's disease is treated by attempting to reverse the neurodegeneration itself, rather than just treating the symptoms of it.
