Controlled-release carbidopa/levodopa in the treatment of Parkinsonism. 1984

J T Hutton, and R L Dippel, and J R Bianchine, and H K Strahlendorf, and P G Meyer

Controlled release carbidopa/levodopa (CSR-1) was compared to standard carbidopa/levodopa in a double-blind, crossover study of 20 Parkinson's disease patients. The most consistent finding in a variety of clinical measurements was the superiority of standard carbidopa/levodopa to CSR-1. Increased dosages of CSR-1 resulted in reduced Parkinson symptoms, suggesting that a more potent controlled-release formulation might prove to be more efficacious than CSR-1.

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.
