[Comparative study on treatment of somnipathy in patients with hypertension by traditional Chinese medicine and by estazolam].
OBJECTIVE
To study the efficacy of traditional Chinese medicine (TCM) in treating somnipathy in patients with hypertension, and to observe the change of blood pressure after sleep being improved.


METHODS
Two hundred and thirty-nine patients with hypertension accompanied somnipathy were randomly assigned to two groups, 123 patients in the treated group were treated with TCM according to syndrome differentiation, and 116 in the control group treated with Estazolam. Changes of blood pressure, scores of sleep dysfunction rating scale (SDRS), Hamilton anxiety rating scale (HAMA) and treatment emergent symptom scale (TESS) before and after treatment were observed.


RESULTS
TCM showed a significant effect on hypnagogic disturbance, and significantly reduced the scores of insomnia syndromes in early sleep stage, improve the quality of sleep, prolong the sleeping time to fulfill the physiological requirement, the total effective rate being 80.5% (99/123 cases), with the overall effect higher than that (66.4%, 77/116 cases) in the control group (P < 0.05). Along with the improving of sleep, blood pressure, both systolic and diastolic, reduced in both groups, but with the reduction in the treated group superior to that in the control group (P < 0.01), and the rate of reaching target BP (< 140/90 mmHg) in the former was also significantly higher than that in the latter (39.7%, 46/116 cases, P < 0.05). As compared with those in the control group, the occurence of adverse reaction, were less in the treated group (P < 0.05).


CONCLUSIONS
TCM has better efficacy in treating somnipathy of hypertension patients than Estazolam. And the improvement of somnipathy is favorable for improving the hypertensive condition of patient.
