Xadago (Safinamide) in Parkinson's Disease

Xadago (safinamide) is a medication approved for the treatment of Parkinson's Disease (PD) as an add-on therapy to levodopa/carbidopa in patients experiencing "off" episodes. Safinamide works by selectively inhibiting monoamine oxidase B (MAO-B) enzymes, which are involved in the breakdown of dopamine in the brain. By inhibiting these enzymes, safinamide increases the levels of dopamine, potentially improving motor function in PD patients. Clinical trials have demonstrated that safinamide, when used in conjunction with levodopa, can reduce "off" time and improve "on" time without troublesome dyskinesia, which are common challenges in PD management.

The efficacy of Xadago has been evaluated in several clinical studies. In these studies, patients treated with safinamide experienced an improvement in daily "on" time, where their PD symptoms were better controlled, without an increase in dyskinesia. Additionally, safinamide has shown to have a positive effect on both motor and non-motor symptoms of PD, which can significantly impact the quality of life for patients. However, it is important to note that the response to safinamide can vary among individuals, and the long-term effects of the drug are still under investigation.

Neupro (Rotigotine) in Parkinson's Disease

Neupro (rotigotine) is a non-ergoline dopamine agonist used in the treatment of Parkinson's Disease. It is available as a transdermal patch, which provides a continuous delivery of medication over 24 hours. Rotigotine mimics the action of dopamine, a neurotransmitter that is deficient in the brains of PD patients. By activating dopamine receptors, rotigotine can help alleviate the motor symptoms associated with PD, such as tremor, rigidity, and bradykinesia (slowness of movement).

The efficacy of Neupro in treating symptoms of Parkinson's Disease has been established through several clinical trials. Patients using Neupro have shown significant improvements in their motor function compared to those on placebo. The transdermal delivery system of Neupro allows for steady medication levels, which helps in managing the motor fluctuations that PD patients often experience. It is also noted for its utility in early-stage PD as a monotherapy and in later stages as an adjunct to levodopa. Despite its benefits, patients should be monitored for side effects, such as skin reactions at the patch application site and potential sleepiness or sudden onset of sleep.
