The study is designed to answer the question: will nicotine at doses that do not cause serious side effects, show feasibility in treatment of levodopa-induced dyskinesia in patients with Parkinson's disease?
Nicotine will be employed at daily doses lower than those available OTC as smoking-cessation patches, in parkinsonian patients experiencing disabling dyskinesias due to their levodopa treatment. The principal adverse effect from this dose level of nicotine is expected to be nausea on acute administration to nicotine-naive patients. Because tolerance to the effects of nicotine is achieved by repeated dose, the study is designed to gradually escalate from 6 to 24 mg per day, taken in 6 separate oral doses of 6 mg each. The study is designed to see if doses which can be tolerated by parkinsonian patients will also reduce the severity and frequency of the dyskinesias experienced following administration of levodopa, the gold standard medication for Parkinson's disease.

Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.
Proteins associated with sporadic or familial cases of PARKINSON DISEASE.
A condition caused by the neurotoxin MPTP which causes selective destruction of nigrostriatal dopaminergic neurons. Clinical features include irreversible parkinsonian signs including rigidity and bradykinesia (PARKINSON DISEASE, SECONDARY). MPTP toxicity is also used as an animal model for the study of PARKINSON DISEASE. (Adams et al., Principles of Neurology, 6th ed, p1072; Neurology 1986 Feb;36(2):250-8)
A group of disorders which feature impaired motor control characterized by bradykinesia, MUSCLE RIGIDITY; TREMOR; and postural instability. Parkinsonian diseases are generally divided into primary parkinsonism (see PARKINSON DISEASE), secondary parkinsonism (see PARKINSON DISEASE, SECONDARY) and inherited forms. These conditions are associated with dysfunction of dopaminergic or closely related motor integration neuronal pathways in the BASAL GANGLIA.
Parkinsonism following encephalitis, historically seen as a sequella of encephalitis lethargica (Von Economo Encephalitis). The early age of onset, the rapid progression of symptoms followed by stabilization, and the presence of a variety of other neurological disorders (e.g., sociopathic behavior; TICS; MUSCLE SPASMS; oculogyric crises; hyperphagia; and bizarre movements) distinguish this condition from primary PARKINSON DISEASE. Pathologic features include neuronal loss and gliosis concentrated in the MESENCEPHALON; SUBTHALAMUS; and HYPOTHALAMUS. (From Adams et al., Principles of Neurology, 6th ed, p754)
