Amantadine
DESCRIPTION

Amantadine is a drug used as an antiviral and an anti-Parkinson’s disease treatment.

How it works

Amantadine is known as a dopamine promoter. It can prompt the body to release more dopamine by blocking dopamine reuptake by the neurons in the brain. These properties of Amantadine were long considered to be effective in treating Parkinson’s disease, a neurological condition connected to dopamine levels in the body. It also used to be prescribed as an antiviral drug to prevent influenza type A, better known as the common cold.

Amantadine is approved by the FDA to treat Parkinson’s and as an antiviral agent. However, the Centers for Disease Control no longer recommend Amantadine for treatment as an antiviral against influenza in the United States. Other research has also suggests that effectiveness of Amantadine against Parkinson’s is undetermined and lacks substantive evidence.

Uses

Amantadine may be prescribed for treating and preventing types of fly virus. It may also be recommended to treat uncontrolled muscle movements caused by Parkinson’s disease and certain types of medications. Physicians may prescribe the drug for other conditions as well.

Dosage

Dosage will be determined by the type of the condition being treated, physician recommendation among other concerns.

The normal recommended dose of Amantadine 100mg per day. The tablets should be taken orally in a single dose or two divided doses. The twice daily dose is recommended if the drug causes side effects affecting the central nervous system.

For Parkinson’s disease, the recommended dose is 100mg oral tablets taken twice a day.

Follow the dosage instructions exactly as prescribed by your doctor for the treatment to be effective. Stick to a dosage schedule to avoid missing doses.

Swallow tablets whole without breaking or crushing. You can take Amantadine with or without food.

Try not to take double doses to make up for a missed dose. If you do miss a dose, take it soon as possible only if the next dose is not due soon.

When taking Amantadine for influenza, it’s very important to follow the complete dosage schedule, even if you feel better. Stopping treatment prematurely may cause the viral infection to return.
