Pharmacotherapy in congestive heart failure: COX-2 inhibition: a cautionary note in congestive heart failure.
NSAIDs have been a mainstay of therapy for rheumatologic diseases for a number of years. Unfortunately, their use was accompanied by sometimes unacceptable gastrointestinal and/or renal side effects. Therefore, safer treatment options were sought. In the process of such a search, selective cyclo-oxygenase-2 inhibitors were identified. Drugs in this class have anti-inflammatory properties similar to NSAIDs and did not produce anywhere near the same pattern of NSAID-related gastrotoxicity. The enthusiasm for this class of drugs would appear, at least on the surface, to be well grounded. However, establishing the renal side effect profile of the selective cyclo-oxygenase-2 inhibitors would appear to be a work in progress. Formal studies with selective cyclo-oxygenase-2 inhibitors have not been conducted in the congestive heart failure population. Information does though exist for other patient cohorts--similarly "prostaglandin-dependent" for their integrity of renal function, such as the elderly and sodium-deplete individual. These data would strongly suggest that the selective cyclo-oxygenase-2 inhibitors could decrease glomerular filtration rate and stimulate salt and water retention, comparable to what occurs with nonselective NSAIDs. To date, no compelling information exists, which supports the notion that differences exist among the currently available selective cyclo-oxygenase-2 inhibitors--celecoxib and--in the potential to negatively impact renal function in this and similarly compromised patient populations.
