阿托伐他汀钙对高血压病患者血脂异常的疗效及对高敏C反应蛋白的影响

Objective To investigate the effect and safety of atovastatin calcium on dyslipidemia and hypersensitive C-reactive protein in hypertension patients. Methods One hundred and twenty-eight hypertensive patients with dyslipidedmia were divided into two groups: control group and treatment group. All patients were in low-fat and low-cholesterol diet and received antihypertensive treatment as usual. Patients in treatment group took atovastatin (20 mg/day) for 12 weeks. Systolic blood pressure (SBP), diastolic blood pressure(DBP), serum total glycerin (TG), total cholesterol ( TC ), low-dense-lipoprotein cholesterol ( LDL-C ), high-dense-lipoprotein cholesterol (HDL-C), very low-dense-lipoprotein cholesterol (VLDL-C), hypersensitive C-reactive protein (hs-CRP), creatinin (Cr), glutamate pyruvate transaminase (ALT) and creatine kinase (CK) were measured before and after the treatment. Results In patients with atovastatin treatment, TG was reduced 16%[(1.6 ±1.2)mmoL/L vs (2.0 ±0.9) mmol/L, P ＜ 0.05], TC was reduced 24% [(4 ± 1 ) mmol/L vs (6 ± 1 ) mmoL/L, P ＜ 0.01], LDL-C was reduced 34% [(3 ± 1 ) mmol/L vs (4 ± 1 ) mmol/L, P ＜ 0.01] and hs-CRP was significantly reduced [(2.3 ± 1.5 )mg/L vs (5.3 ± 2.9)mg/L, P ＜ 0.01]. CK increased lightly in two patients with atovastatin treatment and were in normal range in one month although the patients received atovastatin ( 10 mg/day) treatment. Compared to control group, TC, LDL-C, VLDL-C and hs-CRP were significantly reduced in treatment group. There was no significant difference in HDL-C, SBP, DBP, Cr and ALT. Conclusion Atovastatin can decrease hypersensitive C-reactive protein in hypertension patients with dyslipidemia.     

氟伐他汀对缺血性脑卒中患者的疗效观察及护理措施

Objective To explore the effect and nursing main points of fluvastatin on the patients with cerebral arterial thrombosis. Methods Eighty-five patients with cerebral arterial thrombosis were randomly divided into three groups. Group Ⅰ was the negative control group. Group Ⅱ was the conventional-dose therapy group and group Ⅲ was the high-dose therapy group. Each group was treated with related therapy and care. The blood lipids in all groups were tested before the treatment, 4 weeks, 12 weeks and 24 weeks after the treatment; the carotid intima-media thickness (IMT) were measured by the Germany SEQUOIAS-512-B ultra machine before the treatment and 24 weeks after the treatment; At the same time, the side effects of fluvastatin were recorded. Results The results of blood lipid tests showed that the LDL, TC and TG in two treated groups were significantly decreased compared to negative control group (P<0.05). After treated for 24 weeks, the carotid intima-media thickness (IMT) in two treated groups were significantly reduced (P<0.05); the side effects of fluvastatin were infrequent and there was no significant different among the three groups (P>0.05). Conclusion The effects of different doses of fluvastatin on cerebral arterial thrombosis were significantly different. With the dose of fluvastatin increased, the serum LDL-L and TC reduced more obvious and the inhibition on carotid atherosclerosis shows more obvious, and the side effects did not increased.

Clinical and experimental aspects of olmesartan medoxomil, a new angiotensin II receptor antagonist

Olmesartan medoxomil is a new orally active angiotensin II (Ang II) type 1 receptor antagonist. It is a prodrug and is rapidly de-esterified during absorption to form olmesartan, the active metabolite. Olmesartan is a potent, competitive and selective Ang II type 1 receptor antagonist. Olmesartan is not metabolized by the cytochrome P-450 and has a dual route of elimination, by kidneys and liver. In patients with essential hypertension olmesartan medoxomil administered once daily at doses of 10-80 mg dose-dependently reduced diastolic blood pressure (DBP). Troughto-peak ratios for both DBP and systolic blood pressure (SBP) were above 50%. At the recommended once-daily starting doses, olmesartan medoxomil (20 mg) was more effective than losartan (50 mg), valsartan (80 mg) or irbesartan (150 mg) in reducing cuff DBP in patients with essential hypertension. The results of cuff SBP and mean 24-h DBP and SBP were similar to those of cuff DBP measurement. In mild-to-moderate hypertensive patients the recommended starting dose of olmesartan medoxomil was as effective as that of amlodipine besylate (5 mg/day) in reducing both cuff and 24-h blood pressure. In lowering DBP olmesartan medoxomil, at 10-20 mg/day, was as effective as atenolol at 50-100 mg/day. In mild-to-moderate hypertensive patients, olmesartan medoxomil, at 5-20 mg once daily, was more effective than captopril at 12.5-50 mg twice daily. At 20-40 mg once daily olmesartan medoxomil was as effective as felodipine, at 5-10 mg once daily. Olmesartan medoxomil has minimal adverse effects with no clinically important drug interactions. Animal studies have shown that olmesartan medoxomil provides a wide range of organ protection. Olmesartan medoxomil ameliorated atherosclerosis in hyperlipidemic animals and ameliorated cardiac remodeling and improved survival in rats with myocardial infarction. Olmesartan medoxomil has renoprotective effects in a remnant kidney model and type 2 diabetes models. Future investigation should reveal whether these beneficial effects of olmesartan medoxomil are applicable to human diseases.     

Safety and antihypertensive efficacy of carvedilol and atenolol alone and in combination with hydrochlorothiazide

Carvedilol has been shown to be effective and safe in patients with essential hypertension when given as monotherapy. In this double-blind, randomized, group-comparative study, 2 groups of 59 patients with mild to moderate essential hypertension [median supine systolic/diastolic blood pressure at baseline (SBP/DBP), 168/105 mm Hg] were treated with either 25 mg carvedilol once daily (o. d.) or 50 mg atenolol o. d. for 4 weeks. Responders at 4 weeks (DBP, < 90=" mmhg)=" terminated=" the=" study.=" nonresponders=" continued=" the=" study.=" hydrochlorothiazide=" (hctz)=" was=" added=" at=" 25=" mg=" o.=" d.=" for=" a=" further=" 6=" weeks.=" the=" median=" blood=" pressure=" decreased=" under=" monotherapy=" with=" carvedilol=">n = 59) from 167/105 at baseline to 155/94 mmHg after 4 weeks, and in the atenolol group (n=59) it decreased from 168/105 to 162/97 mmHg. The patients who received carvedilol in combination with HCTZ and were evaluated for efficacy (n = 38) showed a decrease in SBP/DBP from 156/97 at the end of monotherapy to 145/88 mmHg after 10 weeks; the combination of atenolol with HCTZ (n = 44) reduced BP from 162/97 to 147/88. Both carvedilol and atenolol were safe when given either alone or in combination with HCTZ. In conclusion, after long-term administration, 25 mg carvedilol o. d. and 50 mg atenolol o. d. significantly reduced both SBP and DBP over 24 h. The addition of HCTZ led to a further increase in antihypertensive efficacy. Combined treatment with carvedilol or atenolol and HCTZ was very well tolerated, without hypotensive events or relevant changes in objective safety parameters.     

Antihypertensive effect of carteolol in thiazide-treated hypertensive subjects

The antihypertensive effect of carteolol, a new potent nonselective beta-adrenergic antagonist, was investigated in a double-blind, parallel study of 35 patients with mild-to-moderate, essential hypertension whose blood pressures were not adequately controlled with a diuretic. Patients were randomly assigned to receive placebo, carteolol 5 mg, or carteolol 20 mg once a day in addition to hydrochlorothiazide 50 mg for six weeks. Thirty-four patients completed the study: 11 patients received placebo (group 1), 12 patients received carteolol 5 mg (group 2), and 11 patients received carteolol 20 mg (group 3). After six weeks of treatment, the two groups that received carteolol had significant reductions in systolic (SBP) and diastolic (DBP) blood pressure from baseline in both the supine and standing positions. In group 2, mean SBP decreases for supine and standing positions were 11 +/- 2.1 and 11 +/- 1.9 mm Hg, respectively (P less than .01) and 8 +/- 1.2 and 9 +/- 1.3 mm Hg, respectively, for DBP (P less than .01); whereas in group 3, values were 8 +/- 2.8 and 12 +/- 3.0 mm Hg for SBP, in 5 +/- 1.9 and 9 +/- 3.1 mm Hg, respectively, for DBP (P less than .01). The hypotensive effect was associated with slight but significant decreases in heart rate (P less than .01 in group 2 and P less than .05 in group 3). Reductions in SBP and DBP with the 20-mg dose were not significantly different from those with the 5-mg dose.2+ moderate hypertension.
