Short General Description of Symmetrel (Amantadine)

Symmetrel (amantadine) is an antiviral medication that is primarily prescribed to treat and prevent influenza A virus infections in adults. It belongs to a class of drugs known as adamantane derivatives.

Amantadine works by inhibiting the replication of the influenza A virus, preventing it from spreading and causing illness. It does this by blocking a specific protein called M2 ion channel, which is essential for viral replication.

In addition to its antiviral properties, Symmetrel also has some antiparkinsonian effects and is commonly used in the treatment of Parkinson’s disease. It is believed to work by increasing the release of dopamine, a neurotransmitter that is deficient in individuals with Parkinson’s disease.

Indications

Symmetrel is primarily indicated for the treatment and prevention of influenza A virus infections in adults.

It may also be prescribed for:

  • Preventing influenza A virus infections in individuals at high risk, such as healthcare workers or individuals with weak immune systems
  • Reducing symptoms of Parkinson’s disease, including tremors, stiffness, and difficulty with muscle control
  • Improving motor function in individuals with drug-induced extrapyramidal reactions

Dosage and Administration

The recommended dosage of Symmetrel may vary depending on the indication for use. It is important to follow your healthcare provider’s instructions and the instructions provided on the prescription label.

For the treatment and prevention of influenza A virus infections, the usual dosage is:

Patient Group Dosage
Adults aged 18-65 200 mg per day, taken as a single dose or divided into two doses of 100 mg
Adults over 65 or with renal impairment 100 mg per day

For the treatment of Parkinson’s disease, the starting dosage is usually 100 mg per day, which may be increased gradually as directed by your healthcare provider.

It is important to note that Symmetrel should be taken with food to improve absorption and minimize potential gastrointestinal side effects.

Side Effects and Precautions

Common side effects of Symmetrel may include:

  • Nausea and vomiting
  • Dizziness or lightheadedness
  • Dry mouth
  • Insomnia
  • Blurred vision

More serious side effects are rare but may include:

  • Allergic reactions
  • Confusion or hallucinations
  • Seizures
  • Increased heart rate
  • Difficulty urinating

It is important to inform your healthcare provider about any pre-existing medical conditions or medications you are taking before starting Symmetrel. This includes any history of seizure disorders, heart problems, kidney disease, or psychiatric disorders.

For more detailed information and guidance on Symmetrel, it is always recommended to consult the FDA-approved prescribing information.

Use of Symmetrel (amantadine) in Medical Treatment

Description: Symmetrel, also known as amantadine, is a medication primarily used to treat influenza A virus infections. It belongs to the class of drugs called adamantane antivirals. Symmetrel can be used to prevent or alleviate symptoms of influenza A, as well as for the treatment of Parkinson’s disease and certain respiratory tract infections caused by a specific virus called respiratory syncytial virus (RSV).

1. Influenza A Treatment:

Symmetrel is widely used for the prevention and treatment of influenza A virus infections. It acts by inhibiting the replication of the virus within the body. When taken within 24 to 48 hours after the onset of flu symptoms, Symmetrel can reduce the duration and severity of the illness. It is important to note that Symmetrel is not effective against influenza B or other viral infections.

Important information: It is recommended to consult with a healthcare professional before using Symmetrel for influenza. This ensures appropriate usage, dosage, and potential side effects.

2. Parkinson’s Disease:

Symmetrel is also utilized in the treatment of Parkinson’s disease, a neurodegenerative disorder that affects movement control. Individuals with Parkinson’s disease often experience tremors, stiffness, and difficulty with coordination. Symmetrel helps to improve symptoms by enhancing the release of dopamine, a neurotransmitter that regulates movement and mood.

Effect on Parkinson’s symptoms: Symmetrel can reduce tremors, muscle stiffness, and problems with muscle control in Parkinson’s patients.

Usage: Symmetrel is usually prescribed as an adjunct therapy along with other medications for Parkinson’s disease, such as levodopa. The dosage and administration schedule varies based on the individual’s condition and response to treatment. It is essential to follow the healthcare provider’s instructions for optimal outcomes.

3. Respiratory Syncytial Virus (RSV) Infections:

In some cases, Symmetrel may be used to treat respiratory tract infections caused by the respiratory syncytial virus (RSV). RSV infections primarily affect the lungs and respiratory system, particularly in young children and older adults. Symmetrel helps reduce the severity and duration of symptoms associated with RSV infections.

Special considerations: Symmetrel is not routinely recommended for the treatment of RSV infections, and its use is typically reserved for specific cases under the guidance of a healthcare professional.

Overall, Symmetrel is a versatile medication utilized in the treatment and prevention of influenza A virus infections, management of Parkinson’s disease symptoms, and selected cases of respiratory syncytial virus infections. It exerts its therapeutic effects by inhibiting virus replication, enhancing dopamine release, and mitigating symptoms associated with respiratory infections.

Use of Symmetrel (Amantadine) in Treatment

Symmetrel, also known by its generic name amantadine, is a medication primarily used in the treatment of Parkinson’s disease and certain viral infections. It falls under the category of antiviral drugs and dopaminergic agents, providing a dual-action therapeutic effect.

Parkinson’s Disease Treatment

Symmetrel has shown significant efficacy in managing the symptoms of Parkinson’s disease, a neurodegenerative disorder characterized by movement difficulties, tremors, and muscle stiffness. It works by:

  1. Stimulating the release of dopamine, a neurotransmitter responsible for coordinating muscle movements, in the brain.
  2. Blocking the reuptake of dopamine, enabling more of the neurotransmitter to be available for use.

These effects help improve muscle control, reduce tremors, and enhance overall mobility in individuals with Parkinson’s disease.

Treatment of Influenza A

Symmetrel’s antiviral properties make it effective in the prevention and treatment of influenza A, a common type of influenza virus. It functions by inhibiting the replication of the virus within the body, reducing the duration and severity of flu symptoms. Symmetrel is particularly beneficial when taken within a short period after flu symptoms appear.

Additional Uses of Symmetrel

Aside from its primary applications, Symmetrel has also been explored for various off-label uses. These include:

  • Treating fatigue in individuals with multiple sclerosis
  • Improving cognitive function in individuals with traumatic brain injury
  • Managing hallucinations and delusions associated with Parkinson’s disease and certain psychiatric conditions

It is advisable to consult a healthcare professional before considering Symmetrel for off-label uses to ensure its appropriateness and safety for individual cases.

Important Considerations and Precautions

While Symmetrel offers therapeutic benefits, it is crucial to be aware of the following:

  • It may cause side effects like dizziness, dry mouth, constipation, and blurred vision. Immediate medical attention should be sought if severe side effects occur.
