Overview
Medical Therapy
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 dopamine neurons degeneration[11] but other studies demonstrated that it does not damage neurons.[12][13]
- Dopamine agonists: Dopamine agonist such as bromocriptine, pramipexole and ropinirole are proved to be effective in managing motor symptoms of PD patients.[14] At first, the use of dopamine agonist were limited t the condition where there is reduced levodopa response or when we had disturbing levodopa complications[15][16] but since dopamine agonists have fewer side effects, some experts suggest using these drugs as the first line therapy especially for PD patients under 60 years old.[17] The adverse effects of dopamine agonist are nausea, vomiting, sleep disorders, confusion, peripheral edema and valvular heart disease.[18][19]
- Monoamine oxidase (MAO) B inhibitors: MAO B inhibitors such as selegiline, rasagiline and safinamide are proved to be helpful in managing motor symptoms of PD patients.[20][21][22][23] these drugs can cause nausea and headaches.[21] Rasagiline can also cause impulse control disorders.[24]
- Anticholinergic agents: In PD we have reduced amount of dopamine and excess amount of cholinergic effects, so anticholinergic drugs such as trihexyphenidyl and benztropine can reduce the symptoms of PD.[25][26][27]
- Amantadine: Amantadine, an antiviral drug can improve PD symptoms by increasing dopamine release, inhibition of dopamine reuptake, stimulation of dopamine receptors and anticholinergic effect.[28][29] Some studies showed that in controlling bardykinesia, this drug can be more effective than anticholinergic drugs.[30]
- Catechol-O-methyl transferase (COMT) inhibitors: The catechol-o-methyl transferase (COMT) inhibitors such as entacapone and tolcapone can potentiate the effect of levodopa in reducing PD motor symptoms.[31][32]
- Estrogen: In postmenopausal women who are experiencing motor fluctuation on antiparkinsonism drugs we can use low dose estrogen to improve their condition.[33][34]
- Other agents: Other drugs such as Exenatide[35], uric acid[36], isradipine[37], nilotinib[38] and GDNF infusion[39] can be effective in controlling PD patients symptoms.
Treatment choices for some of the nonmotor symptoms of PD are:
- Psychosis: Drugs such as quetiapine, clozapine and pimavanserin are used in managing psychosis in PD.(10_15) one of the side effects of clozapine is leukopenia and agranulocytosis.(14)
- Dementia: Cholinesterase inhibitors such as rivastigmine and donepezil are the main treatment of dementia in PD.(130_131_138)
- Fatigue: Amantadine, methylphenidate and pemoline can improve fatigue in PD patients.(21_22_23)
- Depression: Amitriptyline(24), desipramine, citalopram(25),paroxetine, venlafaxine(28), ropinirole and pramipexole(11_29_30) are useful in managing depression in PD patients. If we intent to use tricyclics we should be aware that their anticholinergic effect can increase orthostatic hypotension and cognitive impairment(13) and for SSRI we should know that they can cause dystonia, tremor and parkinsonism.(34) the combination of MAO B inhibitors with SSRIs or tricyclics can cause serotonin syndromes(48)
- Constipation: Increasing probiotics and fibers, lubiprostone and polyethylene glycol are effective in treatment of constipation.(51_52_53)
- Sialorrhea: If the sialorrhea is mild we can treat it with chewing gum and hard candy(54_55) but in severe cases, botulinum toxin injection into salivary glands is helpful.(11_56 ta 59)
- Sexual dysfunction: Male sexual dysfunction can be treated with sildenafil.(66)
- Ortostatic hypotention: Fludrocortisone(29), Sympathomimetic agents such as ephedrine, pseudoephedrine, methylphenidate and dextroamphetamine are used to treat orthostatic hypotension.(33_34_35)
