Amantadine hydrochloride

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.

Additional information:

  • Amantadine hydrochloride is available in capsule and liquid forms.
  • It is typically taken orally, once or twice daily, with or without food.
  • Common side effects include dizziness, lightheadedness, confusion, fatigue, and nausea.
  • It can interact with other medications, so it is crucial to inform your doctor about all medications you are taking before starting amantadine.
  • Pregnant or breastfeeding women should not take amantadine hydrochloride without consulting their doctor.
