1 The aim of the present study was to determine the effect of chronic oral treatment with a new angiotensin II type 1 (AT(1)) receptor antagonist, RNH-6270 (the active form of olmesartan medoxomil), on cardiovascular responses to excitatory amino acids in the RVLM of SHR. olmesartan angiotensinogen Rattus norvegicus
2 These results demonstrated that chronic oral treatment with RNH-6270, an AT(1) receptor antagonist, partly normalizes the pressor responses to L-glutamate or NMDA, but not (1S,3R)-ACPD, in the RVLM of SHR, suggesting that endogenous angiotensin II may be involved in the exaggerated pressor response to l-glutamate, probably through its ionotropic glutamate receptors. olmesartan angiotensinogen Rattus norvegicus
