1. Dear Drugs-Forum readers: We are a small non-profit that runs one of the most read drug information & addiction help websites in the world. We serve over 4 million readers per month, and have costs like all popular websites: servers, hosting, licenses and software. To protect our independence we do not run ads. We take no government funds. We run on donations which average $25. If everyone reading this would donate $5 then this fund raiser would be done in an hour. If Drugs-Forum is useful to you, take one minute to keep it online another year by donating whatever you can today. Donations are currently not sufficient to pay our bills and keep the site up. Your help is most welcome. Thank you.

The Role of Ketamine in the Treatment of Chronic Pain (Edmonds, 1998)

The Role of Ketamine in the Treatment of Chronic Pain (Edmonds, 1998)

    There has been increasing clinical interest in the role of the non-competitive N-methyl-D-aspartate (NMDA)
    antagonist ketamine for the management of complex pain states. In vivo and in vitro studies increasingly suggest involvement of the NMDA receptor complex in a variety of chronic pain states associated with the clinical features of allodynia, central hypersensitivity and plasticity. This article explores the evidence for the role of the NMDA receptor complex in acute and chronic pain, and for the therapeutic use of NMDA receptor antagonists such as ketamine. It concludes with a discussion of the adverse effects of ketamine and some recommendations for its clinical use.
