Parsitan (generically known as ethopropazine) is a prescription oral medication used to treat the symptoms of Parkinson’s disease, improve muscle control, reduce stiffness, and limit tremors and abnormal muscle movements.  

Ethopropazine works by blocking the action of acetylcholine, a chemical messenger in the brain that is involved in movement control. By blocking the activity of acetylcholine, it can help to reduce the symptoms of tremors, stiffness, and slow movement that are associated with Parkinson’s disease. 

Use and Dosage 

Parsitan comes in the form of a tablet to take it orally with or without food with effects to be noticed within a few days. Swallow the whole tablet without crushing and chawing it down. Chewing or crushing tablets that are not designed to be chewed or crushed can alter the way the medication is absorbed by the body and can potentially cause harm. 

The usual adult dose of Parsitan is one tablet, taken 2-3 times daily, with or without food. The dosage may be adjusted as needed, based on the individual’s response to the medication. Follow the instructions of the prescribing healthcare provider and do not take more or less of the medication than prescribed. 

Abruptly stopping Parsitan tablet may cause withdrawal symptoms, such as confusion, hallucinations, and delirium, especially in older adults.  

If you miss a dose of Parsitan tablet, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
