Measure
IPX203 First Then Sinemet
Participants first received IPX203 ER CD-LD Capsules for 15 days After a Washout Period of 7 days; participants then received Sinemet (IR CD-LD) Tablets for 15 days Study drug doses were determined based on the subject's prestudy IR CD-LD regimen The typical IPX203 dosing regimen was 3 times a day, dosed approximately every 7 to 8 hours.
Sinemet First Then IPX203

All Study Participants
n=28 Participants
The recommended first morning dose of IPX203 on Day 1 was based on the subject's prestudy IR CD-LD morning dose The initial IR CD-LD dosing regimen was the same as the subject's stable prestudy regimen (unless s/he was taking a single daily bedtime dose of CR CD-LD, either alone or in combination with IR CD-LD, in which case, the CR CD-LD dose was discontinued and substituted with a 1:1 milligram-equivalent IR CD-LD dose).
