While immediate-release granules dissolve rapidly, the extended-release pellets inside 
CREXONT® (carbidopa and levodopa) are built to last. Each ER pellet is designed with 
a novel mucoadhesive polymer that helps the levodopa reach the optimal area of 
absorption, where it can release slowly, making CREXONT the oral CD/LD therapy with 
the longest-lasting LD plasma levels.1-3*†
*Based on the time that LD plasma levels were maintained above 50% of Cmax. 
†Exact site and duration of absorption are unknown.
CD/LD=carbidopa/levodopa; Cmax=maximum observed plasma concentration; ER=extended-release; LD=levodopa.
