You are unique. And so is RYTARY.*

Every RYTARY capsule contains a unique combination of time-released carbidopa/levodopa (CD/LD) beads.

*Compared to IR CD/LD.

This is what makes RYTARY different.

Together, these beads allow RYTARY to work (absorb) quickly—and keep working for up to 4 to 5 hours—to treat the symptoms of Parkinson’s disease.

In comparison, IR CD/LD medications only provide an immediate dose of medication. Levodopa levels look like a series of peaks and valleys over the course of a day.

The chart below is based on a single-dose study of RYTARY in healthy volunteers; pharmacokinetic level was projected over 12 hours.


RYTARY works to smooth out those peaks and valleys created by IR CD/LD by quickly delivering levodopa and then extending levodopa levels over a longer period of time. This may reduce the amount of “off” time you experience each day.

When I told my doctor about how often I was experiencing ‘off’ time, we talked about switching to extended release RYTARY. Our hope was that it would keep me on a more even keel, and it does do that for me.

Let RYTARY help the real you
shine through.

Taking RYTARY may result in:
reduction in “off” time compared with
Immediate-Release (IR) CD/LD

In a clinical study, people with advanced Parkinson’s disease taking RYTARY experienced a 13.1% reduction in “off” time during waking hours (compared with only 6.2% for people taking IR CD/LD).

  • RYTARY at study start and study end§: 36.9% to 23.8%
  • IR CD/LD at study start and study end§: 36.0% to 29.8%
Better movement control

RYTARY also improved motor symptoms compared with IR CD/LD, which may help you perform daily activities. ||

“Waking hours” is a term used to describe the hours during a day in which you are awake. The primary measurement in this study was the percentage of “off” time during waking hours.
§Study end = Week 22 or early termination.
||This was a secondary measure of the study.
I have more ‘on’ time with RYTARY. Parkinson’s doesn’t stop me from stretching and staying physically active as my doctor recommended.

RYTARY was shown to have
a similar safety profile as IR CD/LD.

In a clinical study, the most common side effects occurring in at least 5% of people treated with RYTARY and at a higher rate than IR CD/LD were nausea and headache.
I wasn’t surprised when I had a little trouble with nausea at first, and a slight dose adjustment was needed. RYTARY definitely gives me more ‘on’ time, so it’s been a great choice for me.
