12/17/1982 - "vert.), given after St 91 (16 micrograms/kg i.v.) abolished the residual bradycardia whereas pretreatment with piperoxan (150 micrograms/kg, intracisternally) inhibited both the initial and the residual bradycardia. "
10/01/1982 - "Baroreceptor reflex activation induced bradycardia was inhibited by yohimbine or piperoxane injected into the cisterna magna or microinjected bilaterally into the nucleus tractus solitarius. "
12/01/1983 - "The clonidine induced bradycardia and hypotension were antagonized by piperoxan pretreatment. "
05/01/1986 - "Clonidine (3 micrograms/kg, i.c.v.) and B-HT 933 (100 micrograms/kg, i.c.v.) induced a bradycardia which was fully reversed by piperoxan (30 micrograms/kg, i.c.v.). "

12/01/1983 - "The clonidine induced bradycardia and hypotension were antagonized by piperoxan pretreatment. "
05/01/1982 - "Pretreatment with 250 microgram of yohimbine and with 500 microgram of piperoxan inhibited the clonidine hypotension, but pretreatment even with 2 mg of either of these drugs did not affect the methoxamine hypertension. "
01/01/1982 - "4. p-Octopamine hypotension was not antagonized by piperoxan, yohimbine and prazosin, a relatively selective antagonist of post-synaptic alpha adrenoceptors. "
02/01/1978 - "In conscious rats, the hypotension and metoprolol, but were unaffected by pretreatment with phentolamine, piperoxan, fluphenazine or methysergide. "

07/01/1982 - "1. 170 150 (imidazolinyl-2)-2-benzodioxane 1-4), as does piperoxan, competitively antagonizes the hypertension induced by clonidine in the pithed rat. "

07/01/1985 - "S 3341 reduced hypertension and tachycardia due to stimulation of the sympathetic outflow in the pithed rat, an effect also antagonised by piperoxan. "

05/01/1982 - "Pretreatment with 250 microgram of yohimbine and with 500 microgram of piperoxan inhibited the clonidine hypotension, but pretreatment even with 2 mg of either of these drugs did not affect the methoxamine hypertension. "

07/01/1985 - "S 3341 reduced the tachycardia resulting from stimulation of the cardioaccelerator nerve in the anaesthetized, spinalised and bilateraly vagotomised dog, this effect was reversed by piperoxan. "
07/01/1985 - "S 3341 reduced hypertension and tachycardia due to stimulation of the sympathetic outflow in the pithed rat, an effect also antagonised by piperoxan. "
10/01/1982 - "Piperoxan microinjection into nucleus tractus solitarius elicited a mild but significant tachycardia and could also block the noradrenaline and clonidine responses. "
10/01/1982 - "Conversely, piperoxan, but not metoclopramide, reduces the bradycardia and inhibition of stimulation-evoked tachycardia produced by M-7. "
04/01/1985 - "Microinjection of monoamines, noradrenaline, phenylephrine and 5-hydroxytryptamine (5-HT) into nucleus dorsalis raphe elicited hypertension and tachycardia which could be blocked by local pretreatment with piperoxan (an alpha-adrenoceptor blocker) and methysergide (a 5-HT receptor blocker) respectively.
