An Antiviral Medication for Dementia?

Amantadine began its pharmaceutical life as a treatment of influenza. For decades it has been a mainstay in the management of Parkinson’s disease. It is prescribed off-label for its ability to reduce symptoms of depression, ADHD, and traumatic brain injury. But changes in how it is thought to work, in combination with clinical research, indicate it might be a powerful tool for treating Alzheimer’s, the most common form of dementia. Many medications wind up being used for purposes far from their original indications. Rather than viewing this as a flaw in the pharmaceutical research process, it reflects that many molecules have a multitude of ways of interacting with human bodies.

Their Personal View also provides insight into the reasons why amantadine is not so widely used and emphasises the fact that, even though this drug has been available for 50 years, its complex pharmacology is still not fully understood nor are the mechanisms behind its beneficial effects.

Amantadine: reappraisal of the timeless diamond—target updates and novel therapeutic potentials

Amantadine was initially developed in early 60s and registered for anti-influenza A2 activity in 1966 (Gerzon et al. 1963; Maj et al. 1974). Few years later, a woman suffering from Parkinson’s disease observed radical improvement of symptoms after taking amantadine taken for ani-viral purposes and reported it to Schwab et al. Following that, the authors performed a clinical study on 163 patients with a positive outcome (Schwab et al. 1969). Following that, he performed a clinical study on 163 patients with a positive outcome. A few years later, amantadine was registered for use in Parkinson’s disease. In the next 5 decades, there were many clinical studies of amantadine in various indications...

StatPearls

Amantadine is an antiviral agent with mild antiparkinsonian activity. Amantadine was used in the early 2000s for Influenza A treatment. However, high levels of resistance have emerged recently, initially from Asia and now in North America. As of 2011, the CDC does not recommend treatment or prophylaxis of influenza A due to the high levels of resistance. Amantadine is now used mostly for Parkinson disease.
