Combined effects of prazepam and trichlormethiazide (TCM) which were given simultaneously were studied in renal hypertensive rats (1-kidney type) and DOCA hypertensive rats. In this study the blood pressure was measured by the plethysmographic method. Orally administered prazepam alone did not show any appreciable effect on the blood pressure, while TCM, even when administered alone, exhibited marked and long-lasting hypotensive effects of both hypertensive rats. In addition, the hypotensive effect of TCM was apparently potentiated by the concurrent use of prazepam. In the experiment where conscious and unconstricted spontaneous hypertensive rats (SHR) were used, the pressor response and tachycardia were observed when foot shock (acute stress) was loaded. This pressor response was the "all or none" type and a threshold existed. In contrast to the pressor response, the degree of tachycardia varied depending on the intensity of the stress. The similar responses were also observed in normotensive rats, although the degrees of the responses were significantly weaker than those in SHR. Prazepam given alone obviously suppressed the cardiovascular responses mentioned above. The present results suggest that prazepam is an useful drug for the treatment of hypertension.
