Sixteen patients with advanced Parkinson's disease (PD) and motor fluctuations were evaluated throughout 12 months of open label therapy on CR4-Sinemet. Reduced dosage frequency and significant motor improvement with reduced fluctuation occurred and were maintained with CR4-Sinemet compared with baseline on Sinemet. In a double-blind protocol using CR4-Sinemet in 20 stable PD patients, CR4-Sinemet was given twice daily and compared with Sinemet given four times daily. Patients remained stable without improvement or deterioration when the long-acting drug was substituted at 50% frequency. Plasma levodopa levels with CR4-Sinemet were smoother than with Sinemet. Although some patients receiving CR4-Sinemet found they functioned more slowly in the morning, the easier dosing schedule and improved amount of "on" time in fluctuators suggest that this formulation may become increasingly useful in managing PD.

UI MeSH Term Description Entries
D007980 Levodopa The naturally occurring form of DIHYDROXYPHENYLALANINE and the immediate precursor of DOPAMINE. Unlike dopamine itself, it can be taken orally and crosses the blood-brain barrier. It is rapidly taken up by dopaminergic neurons and converted to DOPAMINE. It is used for the treatment of PARKINSONIAN DISORDERS and is usually given with agents that inhibit its conversion to dopamine outside of the central nervous system.

D010300 Parkinson Disease A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D002230 Carbidopa An inhibitor of DOPA DECARBOXYLASE that prevents conversion of LEVODOPA to dopamine. It is used in PARKINSON DISEASE to reduce peripheral adverse effects of LEVODOPA.
