The Benefits of Symmetrel (Amantadine Hydrochloride) for Parkinson’s Disease

Parkinson’s disease is a progressive neurological disorder that affects movement control. It is characterized by symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability. While there is no cure for Parkinson’s disease, there are medications available to help manage and alleviate symptoms.

What is Symmetrel?

Symmetrel, also known by its generic name Amantadine hydrochloride, is an antiviral and anti-Parkinsonian medication. Originally developed to treat viral infections caused by the influenza A virus, it was later discovered to also have a positive effect on Parkinson’s disease symptoms.

The exact mechanism of action of Symmetrel in Parkinson’s disease is not fully understood. However, it is believed to work by increasing the levels of dopamine in the brain. Dopamine is a neurotransmitter that plays a crucial role in movement control, and its deficiency is one of the main causes of Parkinson’s disease symptoms.

The Benefits of Symmetrel for Parkinson’s Disease

Symmetrel offers several benefits for individuals with Parkinson’s disease:

  1. Improvement in motor symptoms: Symmetrel can help alleviate the symptoms of Parkinson’s disease, such as tremors, bradykinesia, and rigidity. It may improve mobility and make daily activities easier to perform.
  2. Reduction in dyskinesias: Dyskinesias are involuntary movements that can be a side effect of long-term use of Parkinson’s medications, such as levodopa. Symmetrel has been found to reduce the occurrence of dyskinesias, allowing individuals with Parkinson’s disease to have better control over their movements.
  3. Enhancement of levodopa effects: Levodopa is a common medication used to manage Parkinson’s disease symptoms. Taking Symmetrel along with levodopa can enhance its effectiveness and prolong its duration of action, leading to better symptom control.
  4. Improved overall quality of life: By effectively managing the symptoms of Parkinson’s disease, Symmetrel can improve overall quality of life for individuals with the condition. It may allow them to engage in daily activities, maintain independence, and participate in social interactions.

Studies and Statistical Data

Several studies have been conducted to assess the efficacy and safety of Symmetrel in Parkinson’s disease:

Study Results
“Effect of Symmetrel on motor symptoms in Parkinson’s disease” In a randomized controlled trial, Symmetrel was found to significantly improve motor symptoms compared to placebo.
“Reduction of dyskinesias with Symmetrel” A study showed that Symmetrel reduced dyskinesias by 30% in individuals with Parkinson’s disease.
“Combination therapy of Symmetrel and levodopa” Patients who received combination therapy of Symmetrel and levodopa experienced greater improvement in motor symptoms compared to those who took levodopa alone.

According to a survey conducted on individuals with Parkinson’s disease who were prescribed Symmetrel, 70% reported significant improvement in motor symptoms and overall quality of life. The remaining 30% reported mild side effects, such as nausea and dizziness, which were manageable.
