What is Rytary?
Rytary is a prescription medication used to treat the symptoms of Parkinson's disease [1]. It is an extended-release formulation that combines carbidopa and levodopa [1]. Parkinson's disease is a progressive neurological disorder that affects movement [2].
How does Rytary work for Parkinson's Disease?
Rytary works by delivering carbidopa and levodopa over an extended period. Levodopa is converted to dopamine in the brain, which helps to alleviate the motor symptoms of Parkinson's disease, such as stiffness, tremor, and slowness of movement [1]. Carbidopa helps to increase the amount of levodopa that reaches the brain and reduces some of its side effects [3]. The extended-release formulation is designed to provide more consistent plasma concentrations of levodopa, potentially leading to more predictable symptom control [1].
When can Parkinson's patients start using Rytary?
Rytary can be used by Parkinson's disease patients as initial therapy or as a conversion from other carbidopa-levodopa products [1]. It is indicated for the treatment of motor fluctuations in patients with Parkinson's disease [1].
What are the benefits of Rytary compared to other carbidopa-levodopa treatments?
Rytary's extended-release formulation aims to reduce "off" time, which is a period when Parkinson's symptoms return between doses of medication [1]. This can lead to more consistent symptom control and potentially fewer motor fluctuations throughout the day compared to immediate-release carbidopa-levodopa formulations [1].
What are potential side effects of Rytary?
Common side effects of Rytary can include abnormal dreams, constipation, diarrhea, dizziness, dry mouth, headache, insomnia, nausea, stomach pain, and vomiting [1]. More serious side effects can include involuntary movements (dyskinesias), hallucinations, confusion, and low blood pressure [1]. Patients should discuss any concerns about side effects with their healthcare provider [1].
