Amantadine hydrochloride, also known by the brand name Symmetrel among others, is a medication with two main uses:
1. Treatment of Parkinson's disease:
- It helps manage the symptoms of Parkinson's disease, such as stiffness, tremors, shaking, and difficulty moving.
- It can also be used to control involuntary movements (dyskinesia) that are a side effect of certain medications used to treat Parkinson's disease.
- Its mechanism of action in this context is not fully understood, but it is believed to increase dopamine levels in the brain, a neurotransmitter crucial for movement control.
2. Treatment of influenza A (no longer recommended):
- Historically, it was used to prevent and treat influenza A infection.
- However, due to the emergence of widespread drug resistance among influenza A viruses, this use is no longer recommended.
- Its antiviral effect worked by blocking the ability of the virus to replicate within the host cells.
