What effects and impacts may rasagiline have after long-term use?

Rasagiline As a monoamine oxidaseB (MAO-B) inhibitor, it is a common drug in the treatment of Parkinson's disease. It is especially used as a single drug for early treatment or in combination with levodopa to delay the progression of motor symptoms. The main effects of long-term use of rasagiline are focused on improving the core symptoms of Parkinson's disease such as tremor, bradykinesia and muscle stiffness. It helps to prolong the "on" period and reduce the "off" fluctuations, which has a positive effect on improving the quality of life. However, it should be noted that long-term medication may also cause some pharmacological effects and potential side effects that cannot be ignored.

First, although rasagiline is not likely to cause severe dopamine-related movement disorders, long-term use may still cause minor motor complications, such as increased muscle tone or movement fluctuations, which are usually related to disease progression and the use of other anti-Parkinsonian drugs. In addition, some patients may experience central nervous system-related side effects during long-term use, such as mild anxiety, insomnia, hallucinations or mood swings, especially when the disease is in an advanced stage or when used in combination with levodopa.

In addition, from a metabolic perspective, long-term use of rasagiline has less impact on liver metabolic function, but liver enzyme levels still need to be monitored regularly in patients with abnormal liver function. A few case reports also suggest the possibility of mild dizziness, dry mouth, or gastrointestinal discomfort, which are generally non-serious side effects that are reversible or controllable. Special reminder is that when combined with other MAO inhibitors or antidepressants containing multiple ingredients for a long time, the potential risk of hypertensive crisis or serotonin syndrome should be strictly guarded against.

Overall, rasagiline has stable long-term efficacy and is well tolerated, but it is still necessary to follow up with doctors regularly to evaluate treatment response and side effects so that medication strategies can be adjusted in a timely manner to achieve a balance between symptom control and quality of life.
