Effect of delapril/manidipine vs olmesartan/ hydrochlorothiazide combination on insulin sensitivity and fibrinogen in obese hypertensive patients.
    Internal medicine (Tokyo, Japan), 2008, Volume: 47, Issue:5

    To compare the effect of delapril/manidipine vs olmesartan/hydrochlorothiazide (HCTZ) combination on insulin sensitivity and plasma fibrinogen in obese hypertensive patients.. After a 4-week placebo period, 88 obese, hypertensive (DBP >95 and <110 mmHg) outpatients were randomized to delapril 30 mg/manidipine 10 mg combination or to olmesartan 20 mg/HCTZ 12.5 mg combination for 24 weeks according to a prospective, randomized, open-label, blinded endpoint, parallel group design. At the end of the placebo period and treatment period, clinical BP, fasting plasma glucose (FPG), plasma insulin, insulin sensitivity (by euglycemic hyperinsulinemic clamp) and plasma fibrinogen were evaluated. Insulin sensitivity was expressed as the amount of glucose infused during the last 30 minutes (glucose infusion rate, GIR) in mg/Kg/min. The total glucose requirement (TGR) to maintain a steady-state blood glucose level in response to a defined increase in plasma insulin concentration was also evaluated.. Both combinations significantly reduced SBP/DBP values (-22.3/16.4 mmHg and -22.6/17.2 mmHg, respectively, all p <0.001 vs placebo). GIR was significantly increased only by delapril/manidipine (+3.01 mg/min/Kg, p=0.038 vs placebo), the difference between treatments being significant (p <0.05). TGR was significantly increased by delapril/manidipine (+9.7 g, p=0.034), while it was unaffected by olmesartan/HCTZ. Plasma insulin as well as fibrinogen were significantly reduced by delapril/manidipine (-17.8 pmol/l, p=0.047 and -67.5 mg/dl, p=0.021, respectively), but not by olmesartan/HCTZ, the difference between the two treatments being statistically significant (p <0.05).. In obese hypertensive patients the delapril/manidipine combination but not the olmesartan/HCTZ combination significantly decreased insulin resistance and plasma fibrinogen levels, despite the similar BP lowering efficacy.

Effects of manidipine/delapril versus olmesartan/hydrochlorothiazide combination therapy in elderly hypertensive patients with type 2 diabetes mellitus.
    Hypertension research : official journal of the Japanese Society of Hypertension, 2008, Volume: 31, Issue:1

    The purpose of this study was to compare the combination treatments of manidipine/delapril and olmesartan/hydrochlorothiazide (HCTZ) in elderly diabetic hypertensives. After a 4-week placebo period, 158 hypertensive patients with type 2 diabetes (age range: 66 to 74 years) were randomized to receive combination treatment of 10 mg manidipine plus 30 mg delapril or 20 mg olmesartan plus 12.5 mg HCTZ for 48 weeks in a prospective, parallel arm trial. After 12 weeks, manidipine or HCTZ was doubled in nonresponders (systolic blood pressure [SBP] > or =130 mmHg and/or diastolic blood pressure [DBP] > or =80 mmHg). Patients were checked at the end of the placebo period and every 12 weeks thereafter. At each visit, lying, sitting and standing BP as well as fasting glycemia, glycosylated hemoglobin (HbA1c), electrolytes, uric acid, total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C) and triglycerides (TG) were evaluated. Both combinations reduced sitting SBP (-27.7 and -28.3 mmHg, respectively; both p<0.001) and DBP (-15.1 and -14.8 mmHg, respectively; both p<0.01) with no difference between the two treatments. Standing DBP was more markedly reduced by olmesartan/HCTZ (-19.5 mmHg; p<0.001) than by manidipine/delapril (-14.7 mmHg; p<0.05 vs. olmesartan/HCTZ). No changes in metabolic parameters were observed with manidipine/delapril, whereas an increase in HbA1c (+0.7%; p<0.05), uric acid (+0.4 mg/dL; p<0.05) and TG (+41.3 mg/dL; p<0.05), and a decrease in serum potassium (-0.3 mmol/L; p<0.05) and HDL-C (-3.4 mg/dL; p<0.05) were found in the olmesartan/HCTZ group. In conclusion, both combinations were similarly effective in reducing BP in elderly hypertensive diabetic patients. However, manidipine/delapril offered some advantages in terms of the less-pronounced BP orthostatic changes and absence of metabolic adverse effects.
