Amantadine 100 mg Capsules | Uses, Structure, Dosage & Side Effects

When living with conditions like Parkinson’s disease, movement disorders, or even recovering from the flu, managing symptoms effectively can improve your quality of life. One medication that offers neurological and antiviral benefits is amantadine 100 mg, available as AMDATIME 100 from Steris Healthcare.

Amantadine 100 mg plays a significant role in helping the brain function better, especially for patients facing movement challenges or fighting certain viral infections. This article explains everything — from amantadine uses, mechanism of action, side effects, and structure, to why Steris Healthcare is the smart choice for this treatment.

What is Amantadine 100 mg?

Amantadine 100 mg is a prescription medicine primarily used to manage Parkinson’s disease, drug-induced extrapyramidal symptoms, and in some cases, Influenza A virus infections. It contains amantadine hydrochloride, which has both neurological and antiviral properties.

The capsule helps improve movement, reduce fatigue, and support better brain signaling, making it a go-to option in neurology and infectious disease treatment.

Key Uses of Amantadine 100 mg

1. Parkinson’s Disease & Movement Disorders

One of the main amantadine 100 mg uses is in treating symptoms of Parkinson’s disease such as stiffness, tremors, and slowed movement. It can also help manage levodopa-induced dyskinesia (involuntary movements caused by Parkinson's medications).

2. Drug-Induced Extrapyramidal Symptoms (EPS)

Patients on antipsychotic medications may develop involuntary muscle movements and stiffness. Amantadine hydrochloride helps manage these side effects without compromising the effectiveness of the psychiatric treatment.

3. Influenza A (Antiviral Action)

Although its use in flu treatment has reduced due to resistance, amantadine 100 mg still retains some value in certain viral outbreaks, especially for high-risk patients.

How It Works: Amantadine Mechanism of Action

The amantadine mechanism of action depends on its purpose:

• Neurologically: It increases the release of dopamine in the brain and inhibits its reuptake. Dopamine is the brain chemical that controls movement and mood — making amantadine helpful in Parkinson's.

• Antivirally: It blocks the M2 ion channel of the Influenza A virus, stopping the virus from replicating inside human cells.

This dual-action makes amantadine a unique and multi-functional drug.

Understanding the Amantadine Structure

The amantadine structure is a rigid tricyclic amine, which allows it to pass through the blood-brain barrier easily and act directly on the brain’s neurotransmitters. Its structure also supports its interaction with viral proteins, which explains its dual efficacy in neurology and infectious disease treatment.
