Why it is necessary to control the dosage of rasagiline/alzilate

Rasagiline is a selective monoamine oxidase B (MAO-B) inhibitor, mainly used to treat Parkinson's disease . Its main mechanism of action is to increase the concentration of dopamine by inhibiting monoamine oxidaseB in the brain, thereby alleviating the motor symptoms of Parkinson's disease patients. Dosage control of rasagiline is critical, and here are some of the main reasons:

1. Avoid side effects caused by drug overdose

Rasagiline is a MAO-B inhibitor. Increasing the dose may lead to excessive dopamine accumulation, leading to a series of side effects. For example, excessive use may cause adverse reactions such as nausea, insomnia, and anxiety, and may even trigger hypertensive crisis or "severe side effects" in severe cases.

2. Control treatment effects

In the treatment of Parkinson's disease, the dosage of rasagiline needs to be adjusted according to the patient's individual condition to ensure the best therapeutic effect. If the dose is too low, the expected therapeutic effect may not be achieved, resulting in insufficient relief of symptoms; while a dose that is too high may cause side effects. Depending on clinical needs, the patient's drug dosage may need to be adjusted between 0.5mg and 1mg to ensure maximum drug effect while reducing side effects.

3. Avoid interactions with other drugs

Concomitant use of rasagiline with other drugs may result in drug-drug interactions, especially with other drugs that affect the central nervous system. When used in combination with levodopa, the dose of rasagiline usually needs to be reduced to 0.5 mg to avoid adverse reactions caused by excessive dopamine effects. Therefore, controlling the dose not only ensures the therapeutic benefit of the drug, but also avoids the negative effects of drug-drug interactions.

4. Prevent drug resistance and drug dependence

When rasagiline is used for a long time, excessive dosage may induce drug resistance or drug dependence, resulting in reduced efficacy. Proper dosage control can help reduce this risk and allow the drug to maintain good efficacy during treatment.
