Treatment of neuropathic pain remains a challenge and the role of various analgesics in this setting is still debated. The effects of tramadol, an atypically acting analgesic with a combined opioid and monoaminergic mechanism of action, and morphine, a prototypical opioid, were tested in rat models of neuropathic and nociceptive pain. ⋯ The results of this study are consistent with clinical data supporting the efficacy of opioids in neuropathic pain conditions, and furthermore suggest an additional contribution of the monoaminergic mechanism of tramadol in the treatment of neuropathic pain states.

Satraplatin [BMS 182751, BMY 45594, JM 216] belongs to a series of orally-active platinum compounds with anticancer activity. It was jointly originated by Bristol-Myers Squibb, Johnson Matthey and the Institute of Cancer Research in the UK; however, Johnson Matthey has since ceased involvement with drug development. Subsequently, the agent has been licensed to and is under development with GPC Biotech, Pharmion and Spectrum Pharmaceuticals. ⋯ The patents have been assigned to Johnson Matthey, a multinational chemical company in the UK, which has exclusively sub-licensed these to GPC Biotech under a co-development and licensing agreement with Spectrum Pharmaceuticals. The patents cover the composition of matter and anticancer uses of various platinum-based compounds, including satraplatin. Two of the US patents will expire in 2008 and 2010, respectively, while patents in most other countries will expire in 2009.
