furthermore , the interaction of d , l-nebivolol with the peripheral sympathetic neurotransmission was investigated in pithed rats by electrical stimulation of the spinal cord . d , l-nebivolol and d-nebivolol ( threshold concentration 10 ( -8 ) mol/kg ) were demonstrated to be selective beta 1-adrenoceptor antagonists . l-nebivolol was a factor of 1,000 less potent as beta 1-adrenoceptor blocker .
