Abstract
Case report of 68 year old female with central post-stroke pain successfully treated with oral ketamine. The patient's pain was refractory to conventional pain treatments and she had persistent right hemi-body neuropathic pain with allodynia and hyperalgesia. An intravenous ketamine trial, followed by oral ketamine with titration to 50mg three times a day was beneficial in decreasing allodynia and hyperalgesia, as well as improving functional capabilities. Known side effects including dysphoria, hallucinations, and paranoid feelings were attenuated with benzodiazepines.
