Sixteen patients with Parkinson's disease and therapeutic response fluctuations entered an open-label trial of a controlled-release carbidopa/levodopa preparation, Sinemet CR4. Sinemet CR4 behaved as a slow release preparation. At the end of 6 weeks CR4 treatment, there was an increase in percent "on" time and mean interdose interval; the number of daily doses and "off" periods were diminished and a slight reduction in the variability of plasma levodopa levels was observed.

Eight Parkinson patients with response fluctuations completed an open-label trial of a controlled-release carbidopa/levodopa preparation (Sinemet CR3). At the end of 6 weeks, percent "on" time and mean interdose interval increased, the number of daily doses and "off" periods was decreased, and the variability of plasma levodopa levels and disability scores was reduced. However, response fluctuations continued to occur, day-to-day consistency was poor, and the bioavailability of levodopa appeared less than that of standard Sinemet.
