The mainstay of therapy for motor symptoms of Parkinson disease are:
The mainstay of therapy for motor symptoms of Parkinson disease are: Levodopa, dopamine agonists, monoamine oxidase (MAO) B inhibitors, anticholinergic agents, amantadine, catechol-O-methyl transferase (COMT) inhibitors, estrogen and other drugs such as [[Exenatide]], [[uric acid]], [[isradipine]], [[nilotinib]] and [[GDNF]] infusion.

The mainstay of therapy for motor symptoms of Parkinson disease are: Levodopa, dopamine agonists, monoamine oxidase (MAO) B inhibitors, anticholinergic agents, amantadine, catechol-O-methyl transferase (COMT) inhibitors, estrogen and other drugs such as Exenatide, uric acid, isradipine, nilotinib and GDNF infusion.
Treatment choices for some of the nonmotor symptoms of PD are:
The mainstay of therapy for motor symptoms of Parkinson disease are:
Levodopa: This drug is the most effective in controlling motor symptoms in PD patients.[1][2] If we use levodopa alone, it will convert to dopamine in the peripheral circulation, so we combine it with a decarboxylase inhibitor like carbidopa to prevent this. The ratio of carbidopa_levodopa in tablets are 10/100, 25/100 or 25/250.[3][4] The adverse effects of this drug includes elevated serum homocysteine, low levels of vitamin B12, elevated methylmalonic acid and sensorimotor peripheral neuropathy.[5][6][7][8] It can also cause motor fluctuations, dyskinesia, cramps and dystonia.[9][10] One of the concerns regarding long term use of levodopa is that it may be increase the rate of dopamineneurons degeneration[11] but other studies demonstrated that it does not damage neurons.[12][13]
Estrogen: In postmenopausal women who are experiencing motor fluctuation on antiparkinsonism drugs we can use low dose estrogen to improve their condition.[33][34]
