1. Levodopa: this drug is the most effective medication to control the symptoms of Parkinson's disease. It is absorbed by the nerve cells in your brain and is converted to dopamine.

Anti-Parkinsons drugs are intended primarily for treating Parkinson's disease. They are not psychiatric drugs, which means they are not licenced to treat any mental health problems. The three anti-Parkinson's drugs which may be prescribed with antipsychotics are: Anticholinergic drugs reduce some of the symptoms of Parkinsonism, and reduce the reuptake of dopamine, thereby sustaining the activity of antiparkinson drugs natural neurohormone.
They may be effective in all stages of the disease. All drugs with anticholinergic properties, the naturally occurring belladonna alkaloids atropine, scopolamine, hyoscyaminesome antihistamines with anticholinergic properties, and synthetics such as benztropin Cogentinprocyclidine Kemadrin and biperiden Akineton are antiparkinson drugs of this group.
Although the anticholinergic drugs have only antiparkinson drugs activity against Parkinson's disease, they are useful in the early stages, and may be adjuncts to levodopa as the disease progresses.
Amantadine Symmetrelwas antiparkinson drugs for prevention of influenza virus infection, but has anti-Parkinsonian properties. Its mechanism of action is not known.
It appears to work by direct stimulation of the dopamine receptors.

Bromocriptine is used as a late adjunct to levodopa therapy, and may permit reduction in antiparkinson drugs dosage. Pergolide Permax is similar to bromocriptine, but has not been studied as extensively in Parkinson's disease.
Entacapone Comtan appears to act by maintaining antiparkinson drugs of dopamine through enzyme inhibition. It is used as an adjunct to levodopa was the patient is beginning to experience the on-off effect.
Tolcapone Tasmar is a similar agent, but has demonstrated the potential for inducing severe liver failure.

As such, tolcapone is reserved for cases antiparkinson drugs all other adjunctive therapies antiparkinson drugs failed or are contraindicated. Selegeline is used primarily as an adjunct to levodopa, although some studies have indicated that the drug may be useful in the early stages of Parkinsonism, and may delay the progression of the disease.
Pramipexole Mirapex and ropinirole Requip are believed to act by direct stimulation of the dopamine receptors in the brain. They may be used alone in antiparkinson drugs Parkison's disease, or as adjuncts to levodopa antiparkinson drugs advanced stages.
Recommended dosage Dosages of anti-Parkinsonian medications must be highly individualized.
All doses must be carefully titrated. Key terms Anorexia — Lack or loss of appetite. Anticholigerginc — An agent that blocks the parasympathetic nerves and their actions. This is significant due to antiparkinson drugs striatopallidal synapse being proposed as a target for Parkinson's disease treatment.
This can hopefully restore balance in the basal ganglia motor circuit. These procedures are typically done when patients no longer antiparkinson drugs to antiparkinson drugs. These procedures include transplantation of fetal tissue in an attempt to reestablish the secretion of dopamine in the neostriatum.
Researchers have also attempted strategies of gene therapy. A genetically modified virus was inserted into the subthalamic nucleus of patients with Parkinson's disease. This virus delivered a gene for GADwhich is the enzyme responsible for the biosynthesis of the major inhibitory neurotransmitter, GABA.
In the study, Antiparkinson drugs turned some of the excitatory glutamate-producing neurons in the sub-thalamic nucleus into inhibitory, GABA-producing neurons, improving the symptoms of Parkinson's disease.
Dopamine in the periphery only causes side effects, no antiparkinson effect. It is absorbed by the nerve cells in your brain and is converted to dopamine.
