Abnormalities in sodium homeostasis and in atrial natriuretic peptide (ANP) behavior could play a role in determining and accelerating the development of glomerular hypertension, hypertension, and microalbuminuria in insulin-dependent diabetes. The aim of the present study was to investigate in 32 hypertensive insulin-dependent diabetic patients (HD) with an altered albumin excretion rate the natriuretic response and ANP release to saline load (2 mmol/kg 90 min, and the effects angiotensin converting enzyme inhibitor therapy 2.5 to 5.0 mg cilazapril, once daily), and calcium antagonists (sustained release verapamil: 120 to 240 mg Isoptin Press, once daily, and long acting nifedipine: 20 to 40 mg Adalat AR, twice daily) on sodium homeostasis and albumin excretion rate. Eight normal subjects matched for sex, age, and weight served as controls. The 32 HD patients showed a blunted response in ANP release and sodium excretion during saline infusion in comparison with controls. The cilazapril and verapamil treatments were tested in 16 of the 32 HD patients and were both effective in ameliorating natriuretic and ANP response to saline load and in decreasing albumin excretion rate. The combined cilazapril and verapamil treatment further improved both these parameters in these patients, although blood pressure levels were comparable. The other 16 HD patients underwent sequential verapamil and nifedipine treatment. Verapamil was more effective than nifedipine in improving natriuresis and ANP release to saline load and in lowering the albumin excretion rate. The results of the present study demonstrate that sodium homeostasis and ANP release are altered in hypertensive nephropathic patients, and both cilazapril and verapamil are more effective than nifedipine in ameliorating natriuresis, ANP release, and albumin excretion rate.

Trandolapril/verapamil sustained release (SR) [Tarka] is an oral, fixed-dose combination of the ACE inhibitor trandolapril and the SR formulation of the phenylalkylamine calcium channel antagonist verapamil. It is indicated for the treatment of hypertension in patients who require more than one agent to achieve blood pressure (BP) targets. In the large, randomised, multicentre INVEST (INternational VErapamil SR/trandolapril STudy), a verapamil SR-based treatment strategy that included trandolapril in most patients was as effective as an atenolol-based treatment strategy in reducing the risk of the primary outcome (first occurrence of death [all-cause], nonfatal myocardial infarction [MI] or nonfatal stroke) in patients with hypertension and coronary artery disease (CAD) and was as well tolerated. Trandolapril/verapamil SR is generally more effective at controlling hypertension than either component as monotherapy, and is as effective as a number of other fixed-dose combination therapies. The combination is as well tolerated as trandolapril monotherapy and is at least as well tolerated as verapamil SR monotherapy. In hypertensive patients with type 2 diabetes mellitus in the BENEDICT (BErgamo NEphrologic DIabetes Complications Trial), trandolapril/verapamil SR prolonged the time to the onset of persistent microalbuminuria compared with placebo, as did trandolapril monotherapy. Thus, trandolapril/verapamil SR is an effective option for the treatment of essential hypertension in patients requiring more than one agent to achieve BP targets, including those with compelling indications, such as CAD or type 2 diabetes.
