BACKGROUND: Essential tremor is a kind of dyskinesia disease with a tendency to heredity. β-adnephrin receptor blocker is mainly used for treatment, but the dosage was great, patients could not persist in treatment. Hydrochloric-acid arotinolol, which characterizes by little side effect, is a β-receptor blocking agent combined with blocking effect of α receptor, and is an ideal drug to treat essential tremor in Japan.OBJECTIVE: To observe the reliability and curative effect of hydrochloric-acid arotinolol on essential tremor among Chinese people.DESIGN: Case analysis.SETTING: Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA.PARTICIPANTS: Totally 30 patients with essential tremor, 19 males and 11 females, aged from 21 to 74 years, with course of 1-40 years, average of (15.8±12.6) years, were selected from Neurological Departments of Beijing Hospital of Ministry of Public Health and General Hospital of Beijing Military Area Command of Chinese PLA from April 1999 to December 2000.METHODS: Tremor degree of upper limb, caput and lower limb, degree of dysfunction of hand, tremor degree of hand during writing and circling, and chief complaint of pain caused by tremor were scored before medication and 2, 4 and 6 weeks after medication. Scores were determined as 1 point, 2 points and 3 points according to mild, moderate and severe degree respectively. Evaluated criteria: ① Obviously effective: Differences were more than 7 points before and after treatment. ② Effective: Differences were 6.5-3 points before and after treatment. ③ A little effective: Differences were 3-1.5 points before and after treatment. ④ No changes: Differences were from 1 to -1 points before and after treatment. ⑤ Worse: Differences were less than -1.5 points before and after treatment. Meanwhile, blood pressure and heart rate of patients and side effect of drug were observed.MAIN OUTCOME MEASURES: ① Results of effective evaluation; ②Blood pressure and heart rate before and after treatment; ③ Adverse events and side effect.RESULTS: Totally 30 patients entered the final analysis. ① Among 30 patients with essential tremor, 6 had obvious effect, 11 had effect, 5 had a little effect, 7 had no effect, and 1 was worse. ② Average of blood pressure before treatment was (138.5±14.6)/(84.2±6.4) mm Hg (1 mm Hg=0.133 kPa), and was (130±10)/(79.7±6.3) mm Hg after 1 course. Average heart rate was (77.5±6.4) times/minute before treatment and (75±6.4) times/minute after treatment. The difference was not significant. ③ Among 30 patients, 4 had side effect at various degrees which was accounted for 13.4%; 1 had distress after medication, 1 had agrypnia, 2 had fullness in head and dizziness, and 1 gave up the treatment because of deteriorated tremor.CONCLUSION: Hydrochloric-acid arotinolol can improve tremor symptom of patients obviously and is an effective drug to treat essential tremor with convenient and safe medication.关键词
