Drug Overview
Rytary (Impax Laboratories) is a novel oral capsule formulation of carbidopa and levodopa that contains both an immediate-release and a sustained-release levodopa component. Rytary is dosed three times daily, although its pharmacokinetic profile allows for smoother levodopa levels and consequently fewer motor fluctuations than conventional, immediate-release carbidopa + levodopa.
Rytary was finally approved by the US Food and Drug Administration in January 2015, despite over three years of regulatory scrutiny. Impax’s first submission in December 2011 resulted in a complete response letter requiring a re-inspection of its manufacturing facility. In the meantime, Impax’s former development partner GlaxoSmithKline terminated their agreement, leaving Impax to conclude the regulatory process and commercialize the product by itself.
