| In vivo | Intracisternal injection of 10 μg/kg Talipexole dihydrochloride promotes vagal-mediated reflex bradycardia induced by injection of angiotensin in β-adrenoceptor-blocked dogs. Intravenous administration of Talipexole dihydrochloride at 30 mcg/kg initially caused an increase in blood pressure in cats. Then there is the long-term drop in blood pressure and heart rate[4]. |
