Since most symptoms of PD are caused by a lack of dopamine in the brain, many Parkinson’s drugs are aimed at either temporarily replenishing dopamine or mimicing the action of dopamine. These types of drugs are called dopaminergic medications. They generally help reduce muscle rigidity, improve speed and coordination of movement and lessen tremor.
Always remember that medication is only part of the overall treatment plan for combatting PD. Learn more about the available medications on these pages, but don't forget exercise and complementary therapies.
