ABSTRACT:
A matrix or monolithic drug delivery system for the controlled release of carbidopa and levodopa consists of the two drugs uniformly dispersed in a polymer vehicle at a concentration that is greater than the solubility of either drug in the polymer. Treatment of parkinsonism with the controlled release formulation provides several advantages over treatment with the standard carbidopa/levidopa combinations presently employed.
