Abstract
A variety of neuropharmacological agents were tested to elucidate how chlorpromazine influenced an endotoxin-induced reaction. The results obtained, particularly with beta-adrenergic blocking agents, reserpine and fusaric acid, suggested that the primary locus of chlorpromazine's action was mediated by peripheral beta-adrenergic receptor blockade. Such a locus is compatible with the low doses of propranolol which suppress the reaction, and with successful treatment of shock with dopamine.
