17664022-12	2007	Prazosin (alpha1- and alpha2B-adrenoceptor antagonist, 0.07-0.28 micromol/kg, i.v.)	Prazosin	0-8	adrenoceptor alpha 2B	Rattus norvegicus	10-42	
15087625-11	2004	Prazosin, the alpha 1-/alpha 2B-adrenoceptor antagonist, attenuated the analgesic effect of nitrous oxide and prevented dexmedetomidine-induced reversal of tolerance to nitrous oxide.	Prazosin	0-8	adrenoceptor alpha 2B	Rattus norvegicus	14-44	
8097565-5	1993	The concentration response curve of methoxamine was shifted to the right by the alpha 1/alpha 2B-adrenoceptor antagonist prazosin (0.1 mumol/l) with a pKD of 7.41 and that of UK 14304 by prazosin (0.3 mumol/l) with a pKD of 6.24.	Prazosin	121-129	adrenoceptor alpha 2B	Rattus norvegicus	80-109	
1719824-3	1991	alpha 2-Adrenoceptor ligands inhibited [3H]rauwolscine binding with a rank order of potency characteristic of interaction with the alpha 2B-adrenoceptor [inhibitory constant (Ki) values (in nM) rauwolscine (1.95) greater than ARC-239 (8.52) greater than prazosin (237) greater than oxymetazoline (30,000)].	Prazosin	254-262	adrenoceptor alpha 2B	Rattus norvegicus	131-152
