Cinanserin reduces plasma extravasation after burn plasma transfer in rats

Specific 5-HT2 antagonism reduces systemic burn edema and leukocyte activation after plasma transfer. Reduction of capillary leakage may be partially mediated by leukocyte dependent as well as independent mechanisms. Future studies need to evaluate specific 5-HT2 receptor subtypes to distinguish between local and systemic effects of serotonin antagonists.
