title: The deleterious effects of high dose cimetidine in acute thermal injury.
abstract: Pharmacological doses of cimetidine have been reported to reduce oedema formation in murine burn models. Sprague-Dawley rats subjected to a 30 per cent full-thickness burn were treated with cimetidine (200 mg/kg) pre and post burn. Untreated, burned animals and sham-burned animals were also studied. No beneficial effects of cimetidine were demonstrated. Cimitidine increased the water content in lung, stomach and eschar of burned animals. No differences were seen in serum or urine electrolytes, or extrarenal water loss. Cimetidine did reduce serum hyperosmolality seen in unresuscitated burned animals. Multiple doses of cimetidine following thermal injury were associated with a significant increment in mortality rate.
