Cox-2 Inhibitors are newly developed drugs for inflammation that selectively block the Cox-2 enzyme. Blocking this enzyme impedes the production of the chemical messengers (prostaglandins) that cause the pain and swelling of arthritis inflammation. Cox-2 inhibitors are a new class of non-steroidal anti-inflammatory drugs (NSAIDS). Because they selectively block the Cox-2 enzyme and not the Cox-1 enzyme, these drugs are uniquely different from traditional NSAIDS. This book explores new research in the field.
