Amantadine HCL 100mg is a medication primarily used to treat the symptoms of Parkinson’s disease and influenza A. It’s an antiviral and antiparkinsonian drug.
For Parkinson’s, amantadine works by increasing the release of dopamine, a neurotransmitter vital for movement control. This helps alleviate tremors, rigidity, and other motor symptoms. The exact mechanism isn’t fully understood, but its effect on dopamine release is key.
Against influenza A, amantadine blocks the virus’s ability to enter host cells. It does this by interfering with the M2 protein, a crucial component of the influenza A virus’s replication cycle. This action prevents viral spread within the body.
It’s important to note that amantadine’s effectiveness against influenza A has decreased due to widespread viral resistance. Your doctor will consider this factor before prescribing it for flu.
Dosage and administration vary depending on the condition being treated and individual patient factors. Always follow your doctor’s instructions precisely. Potential side effects include dizziness, insomnia, and nausea. Consult your physician immediately if you experience any adverse reactions.
