Dextromethorphan-Quinidine: not quite ready for prime time

We only chose one article for this month's #GeriMedJC.  It was a randomized controlled trial of dextromethorphan-quinidine for agitation in Alzheimer disease:

Effect of Dextromethorphan-Quinidine on Agitation in Patients With Alzheimer Disease Dementia: A Randomized Clinical Trial. JAMA. 2015 Sep 22-29;314(12):1242-54. 

There was pretty much consensus that dextromethorphan-quinidine is not quite ready for prime time in the management of agitation in Alzheimer disease.  Among some important concerns raised were:

  • trial was funded by pharma
  • last-observation carried forward is not a recommended method for imputing missing data in dementia trials
  • biases introduced by the choice of rescue medication, Lorazepam
  • agitation in this trial lumped together verbal aggression, physical aggression, and non-aggressive activity (pacing, restlessness)
  • mode of action
Thank you to all those who joined in the discussion:

See you on December 18, 2015 at 08:00 ET for the next #GeriMedJC!  Articles will be announced in advance by @GeriMedJC

  2. Unfortunately there are a lot of AIDS/Herpes denials on Herbal cures still out there. I did research on them after I was tested HIV/Herpes positive I was so worried am I going to die soon. I continue my search again on herbal remedy for Std, then I found lots of testimony on how Dr Itua Herbal Medicine Cured HIV/Aids, Herpes Virus,Copd, Hepatitis, Diabetes, On websites sharing their testimonies, which made much more sense to me. All the authors pronounce Dr Itua As a man with Good Heart, I pick interest in their testimonies and I contact him about my situation then he gave me procedure how it works, I proceed after one week he courier his Herbal Medicine to me and instruct me on how to drink it for two weeks to cure. I receive His Herbal Medicine so I drank it for two weeks as I was told then after 2 days I go for a test I found out I was cured from HIV/Aids & Herpes Virus, I pay homage to him 2 months ago to his country to celebrate with him on his African festival which he told me it usually happens every year. I know there are lots of (HIV)/Aids&Herpes Virus denials of Herbal Remedy movement the same few doctors and they represent a very small faction of the community. I could have died because I refused Natural Herbs Cures for so long, but luckily, by the grace of God I am alive to tell my story.
