  • Title: Effects of ketanserin on blood pressure variability in conscious spontaneously hypertensive rats.
    Author: Cheng Y, Kong XB, Su DF.
    Journal: Zhongguo Yao Li Xue Bao; 1992 May; 13(3):235-8. PubMed ID: 1442106.
    Abstract:
    Computerized analysis of blood pressure (BP) was used to study for the effects of ketanserin (Ket) on BP and blood pressure variability (BPV). Rats were instrumented chronically and BP was sampled every 4 ms by a computer from 2:00 to 14:00. Then a single dose of Ket (3 mg.kg-1) was given iv. BP and heart period (HP) were recorded for the next 30 min. The results showed that Ket lowered systolic BP (26.7 kPa to 21.1 kPa), diastolic BP (20.5 kPa to 15.8 kPa), and systolic BPV (1.3 kPa to 0.94 kPa). Otherwise, a positive relationship was found between antihypertensive effects of Ket and BPV. These findings may be of importance in antihypertensive treatment.
