There have been many persons who are interested to know that what are the specific reasons for which the amantidine (commercial link deleted) is considered to be so helpful for the Parkinson’s patients, so I would like to tell in this regard that the said drug has been evident in readily being absorbed by the body and hence traverses smoothly to the brain and its presence has also been witnessed in the saliva and the nasal secretions. What’s more convenient and easy going with amantadine is on requirement it can quite easily be eradicated from the urine and still more than 90% of the dose is available unchanged.
