Doxazosin Mesylate is a selective, long-lasting antagonist of α1-adrenergic receptor [1].
Doxazosin Mesylate has been reported to potentiate contraction response to 5-HT in a dose-dependent manner [1]. Doxazosin significantly reduced alcohol drinking and increased water intake in adult male P rats [2].
Studies has indicated that doxazosin could inhibit TNF-α expression in LPS-induced systemic inflammation model as well as reduce the MCP-1 production in LPS-induced pulmonary inflammation model. Additionally, Doxazosin decreased thickness of footpad in the delayed-type hypersensitivity mice model. Doxazosin had been reported to slightly reduce MCP-1 level in the peritoneal cavity of mice induced by thioglycollate [3].
