| Alternative Names: 1-aminoadamantane, sold as Symmetrel®.. Amantadine is an antiviral drug that was approved by the FDA in 1976 for the treatment of Influenzavirus A in adults. Influenza A virus causes "avian influenza" (also known as bird flu, avian flu, Influenzavirus A flu, type A flu, or genus A flu). Early in the 2005/2006 flu season, the CDC found rates of amantadine resistance to be much higher than in previous seasons: A resistance rate of 92.3% for the major flu strain was called "alarmingly high". Reasons For Use The drug has also been demonstrated to help reduce symptoms of Parkinson's disease. Amantadine has been shown to relieve SSRI-induced Anorgasmia in some people, though not in all people. Side-Effects Amantadine has been associated with several CNS side-effects, including nervousness, anxiety, agitation, insomnia, difficulty in concentrating, and exacerbations of pre-existing seizure disorders and psychiatric symptoms in patients with Schizophrenia or Parkinson's disease. Another possible side-effect of amantadine is livedo reticularis, the dermatological reaction that results in skin mottling and purpurish mesh network of blood vessels. |
