xafinact (SAFINAMIDE)

What is Xafinact?

Xafinact is primarily used to treat Parkinson's disease, often in combination with other medications like levodopa. It works by inhibiting monoamine oxidase B (MAO-B), which breaks down dopamine in the brain, and modulating glutamate release. This helps to improve motor function and reduce symptoms of Parkinson's, such as tremors and rigidity.

What is the usual dose of Xafinact?

The usual daily dose of Xafinact for adults is:

• Initial Dose: 50 mg orally once a day.
• Maintenance Dose: After 2 weeks, the dose may be increased to 100 mg once a day based on individual needs and tolerability.
• Maximum Dose: 100 mg per day.

For children, the use and dosage must be determined by a healthcare provider, as specific dosing guidelines for pediatric patients are not established.

How do I take Xafinact?

Xafinact can be taken with or without food, and there are no specific food restrictions. However, it is important to take the medication as prescribed, and the tablet should be swallowed whole without crushing or chewing. For optimal effectiveness, it should be taken consistently at the same time each day.

For how long do I take Xafinact?

The typical duration of use for Xafinact in treating Parkinson's disease is often assessed in clinical studies lasting 24 to 52 weeks. In these studies, patients are monitored for efficacy and safety, with some participants continuing in open-label extensions beyond the initial study period. Long-term use may be considered based on individual patient response and tolerability.

What disease or symptom is Xafinact used for?

Xafinact is primarily indicated for the treatment of Parkinson's disease. It is used as an adjunctive treatment to levodopa (a standard Parkinson's medication) to help manage motor fluctuations, such as "off" episodes where Parkinson's symptoms worsen despite medication. It can be used in both early and advanced stages of Parkinson's disease.

How long does it take for Xafinact to start working?

Xafinact may take several weeks to show noticeable benefits in patients with Parkinson's disease, as it works gradually to improve motor function. However, the time it takes to experience significant effects can vary depending on the individual and their response to the medication. It's important to follow the prescribed dosing schedule for optimal results.

Is Xafinact effective?

Xafinact has been proven effective in clinical trials for treating Parkinson’s disease, particularly in improving motor function and controlling symptoms like tremors and rigidity. Studies have shown that when added to a stable dose of levodopa, it improves the overall motor response, reduces “off” times (periods when symptoms worsen), and provides better control of symptoms. It works as both a monoamine oxidase-B inhibitor and a glutamate release modulator.

How do I know if Xafinact is working?

The effectiveness of Xafinact is typically evaluated through clinical assessments that monitor improvements in Parkinson's disease symptoms. Key indicators include motor function, assessed by scales like the Unified Parkinson's Disease Rating Scale (UPDRS), and the reduction in "off" time (periods of poor symptom control). Additionally, patient-reported outcomes, such as quality of life and functional ability, are also considered to evaluate the benefit. Regular follow-up with healthcare providers ensures that the medication is contributing positively to symptom management.

How does Xafinact work?

Xafinact works by increasing dopamine levels in the brain and modulating glutamate activity, both of which are important for controlling movement. It is a monoamine oxidase-B (MAO-B) inhibitor that helps prevent the breakdown of dopamine, improving motor control in people with Parkinson's disease. It also has NMDA receptor antagonism properties, which helps balance excitatory signals in the brain, further aiding in the reduction of motor fluctuations.

Who should avoid taking Xafinact?

Xafinact should be used with caution in patients with a history of mental health disorders, such as depression, as it may exacerbate mood changes or lead to suicidal thoughts. It is contraindicated in individuals with hypersensitivity to Xafinact or any of its components, severe hepatic impairment, or those taking certain other medications, such as monoamine oxidase inhibitors (MAOIs). Regular monitoring is recommended for those with a history of cardiovascular issues.

Can I take Xafinact with other prescription drugs?

Xafinact interacts with dopaminergic medications like levodopa, potentially increasing side effects like dyskinesia. It should not be combined with MAO inhibitors (e.g., selegiline) due to the risk of hypertensive crises or serotonin syndrome. Interactions with antidepressants (SSRIs, SNRIs) and antipsychotics can also increase the risk of serotonin syndrome or reduce effectiveness. Always consult a healthcare provider.

Can Xafinact be taken safely while pregnant?

Xafinact is classified as a Category C drug for pregnancy, meaning that there is limited evidence of potential risks to the fetus.
