Effect of dilazep dihydrochloride on serum cardiac troponin T levels in hemodialysis patients.[Pubmed:11834877]

Kidney Blood Press Res. 2002;25(1):50-4.

BACKGROUND/AIM: Cardiac troponin T is a highly sensitive marker for the detection of myocardial injury. We studied whether Dilazep dihydrochloride affects cardiac troponin T levels in hemodialysis patients. METHODS: Our study included 60 hemodialysis patients without symptoms of acute myocardial ischemia. We measured serum cardiac troponin T levels by the Elecsys troponin T assay and randomized 40 hemodialysis patients with left ventricular hypertrophy (LVH) into two treatment groups: a Dilazep dihydrochloride group (300 mg/day, n = 20) and a placebo group (n = 20). Treatment was continued for 12 months. RESULTS: There were no significant differences between pre- and postdialysis cardiac troponin T levels before treatment. LVH was noted in 40 patients out of 60 hemodialysis patients (67%). Cardiac troponin T levels were significantly higher in these patients (0.23 +/- 0.08 microg/l) than in hemodialysis patients without LVH (0.09 +/- 0.03 microg/l). Cardiac troponin T levels were reduced from 0.24 +/- 0.08 to 0.12 +/- 0.06 microg/l (p < 0.01) in patients treated with Dilazep dihydrochloride. There were no change in cardiac troponin T levels in patients receiving placebo (from 0.21 +/- 0.08 at baseline to 0.20 +/- 0.07 microg/l). CONCLUSION: Dilazep dihydrochloride may be effective in ameliorating myocardial damage in hemodialysis patients.

Silent cerebral infarction in patients with type 2 diabetic nephropathy. Effects of antiplatelet drug dilazep dihydrochloride.[Pubmed:15386824]

Diabetes Metab Res Rev. 2005 Jan-Feb;21(1):39-43.

BACKGROUND: To determine whether diabetic nephropathy is a risk factor for silent cerebral infarction and whether antiplatelet drug Dilazep dihydrochloride decreases the occurrence of silent cerebral infarction in type 2 diabetes patients with microalbuminuria. METHODS: Two hundred four type 2 diabetes patients (124 men, 80 women; age, median 56 years, range 42-74 years) and 60 healthy age-matched subjects (no diabetes, normal renal function) were recruited for brain magnetic resonance imaging. The diabetes patients included 40 without nephropathy (group A), 42 with microalbuminuria (20-200 microg/min) (group B), 44 with macroalbuminuria (>200 microg/min) and normal renal function (blood creatinine <132.7 micromol/L) (group C), 33 with chronic renal failure but not undergoing haemodialysis (blood creatinine >132.7 micromol/L; mean creatinine 335.9 micromol/L) (group D) and 45 undergoing haemodialysis (duration; median 4 years, range 3-6 years) (group E). RESULTS: Silent cerebral infarction was found in 20, 29, 34, 45, 53 and 8% of group A, B, C, D, E and control patients respectively. The incidence of silent cerebral infarction was increased with diabetic nephropathy. Thirty group B patients with no silent cerebral infarction were divided into two groups: (B1) 15 treated with Dilazep dihydrochloride and (B2) 15 not treated with Dilazep dihydrochloride. Treatment continued for 24 months. The incidence of silent cerebral infarction was significantly lower in the dilazep-treated patients (6.7%) than in the untreated patients (33.3%) (p < 0.01). CONCLUSIONS: These data suggest that diabetic renal dysfunction increases the risk of silent cerebral infarction and that Dilazep dihydrochloride prevents its onset in early type 2 diabetic nephropathy patients.

Combination AST-120 and dilazep dihydrochloride therapy reduced urinary protein excretion and serum creatinine levels in patients with chronic renal failure.[Pubmed:12380917]

Ren Fail. 2002 Sep;24(5):683-5.

The effect of AST-120 and Dilazep dihydrochloride on serum creatinine levels and urinary protein excretion was assessed in patients with chronic renal failure. We found that both drugs in combination provide an additive renoprotective effect over each drug in some chronic renal failure patients.

Dilazep dihydrochloride prolongs the infarct size-limiting effect of ischemic preconditioning in rabbits.[Pubmed:11560359]

Heart Vessels. 2000;15(5):227-32.

Recent studies have indicated the key role of adenosine receptor activation as a trigger for ischemic preconditioning (PC). Hence, the augmentation of endogenous adenosine may potentiate the cardioprotective effects of PC. In this study. we aimed to test the hypothesis that Dilazep dihydrochloride, an adenosine transport inhibitor, potentiates the PC effect. Protocol 1: Infarcts were produced in open-chest anesthetized rabbits by 30-min occlusion of a coronary artery and 2 days' reperfusion. PC was elicited by a preceding 5-min occlusion and either 5, 40, or 120 min of reperfusion. PC with the 5-min reperfusion markedly limited the infarct size after the 30-min ischemia (infarct size to area at risk (IS): 10%+/-3% vs 41%+/-3%, P < 0.05). PC was not protective when the reperfusion periods were 40 or 120 min (IS: 47%+/-5% and 44%+/-3%. P = not significant (NS) vs control, respectively). However, concomitant treatment with dilazep (0.2mg/kg) preserved the PC effect in the 40-min reperfusion group (18%+/-5%, P < 0.05 vs control) but not in the 120-min reperfusion group (43%+/-4%, P = NS vs control). Protocol 2: Infarct was produced in a similar rabbit model by either a 45- or 50-min occlusion of a coronary artery and 2 days of reperfusion. PC was elicited by a preceding 5-min occlusion and a 5-min reperfusion. PC was protective in the 45-min occlusion group (30%+/-7% vs 67%+/-3%, P < 0.05) but not in the 50-min occlusion group (74%+/-4% vs 79%+/-5%, P = NS). Treatment with dilazep (0.2mg/kg) failed to retrieve protection in this preconditioned group (77%+/-6%, P = NS vs 50-min occlusion group without PC). Thus, dilazep prolonged the infarct size-limiting effect of PC, but failed to retrieve protection in the group with a longer sustained ischemia.

Effect of dilazep dihydrochloride against ischemia and reperfusion-induced disruption of blood-brain barrier in rats: a quantitative study.[Pubmed:1620248]

Naunyn Schmiedebergs Arch Pharmacol. 1992 Apr;345(4):485-8.

The effect of Dilazep dihydrochloride (dilazep) against ischemia and reperfusion-induced disruption of blood-brain barrier (BBB) was quantitatively investigated in Slc:Wistar strain rats using Evans blue dye as a BBB destruction indicator. The forebrain of sham-operated animal had a small amount of the dye. A treatment of 3.5-h ischemia plus 2-h reflow extravasated the dye into the brain and markedly increased the dye content as compared with that of sham group (P less than 0.01 vs. sham group). Continuous infusion (i.v.) of dilazep during cerebral ischemia dose-dependently reduced the increase of the dye content, and a significant reduction was found at 3 mg/kg/h (P less than 0.05 vs. control group). Evans blue dye extravasation after ischemia was also greatly reduced in saline-perfused brains by the treatment with dilazep. Dilazep has been reported to inhibit edema formation in cerebral ischemia model of spontaneously hypertensive rats. These results suggest that dilazep prevents the ischemic damage of BBB, which may contribute to reduction of the brain edema.

Dilazep potentiation of adenosine-mediated superior mesenteric arterial vasodilation.[Pubmed:1890619]

J Pharmacol Exp Ther. 1991 Sep;258(3):767-71.

The present study investigated the effects of dilazep, an inhibitor of adenosine uptake, on adenosine-mediated vasodilation in vivo. Intravenous and intraportal venous infusions of exogenous adenosine (0.04-1.0 mg/kg/min) did not recirculate to cause increases in superior mesenteric arterial conductance (SMAC) or arterial plasma adenosine levels except at the higher doses tested (0.4-1.0 mg/kg/min). After administration of dilazep, however, even low doses (0.04-0.1 mg/kg/min) of exogenous adenosine significantly increased SMAC and elevated arterial plasma adenosine concentration. The increased adenosine levels were highly correlated with the increased percentage of change of SMAC and values for Rmax and EC50 were 193.4 +/- 27.3% change of SMAC and 2.8 +/- 1.3 microM, respectively. Administration of bolus doses of 8-phenyltheophylline abolished the ability of dilazep to potentiate vasodilation, but did not affect isoproterenol-induced relaxation. Together, these results suggest that potentiation of the vasodilating effect of exogenous adenosine by dilazep is mediated through inhibition of adenosine uptake in vivo which increases the availability of plasma adenosine to act on adenosine receptors.

Description

Dilazep dihydrochloride is an inhibitor of adenosine uptake. Dilazep dihydrochloride has cerebral and coronary vasodilating action through enhancement of effect of adenosine. Dilazep dihydrochloride also inhibits the ischemic damage, platelet aggregation, and membrane transport of nucleosides.
