    Metabolic effects of long-term therapy with muzolimine and chlorthalidone in hypertension (1987)

    Notes: Summary Previous short-term studies of muzolimine (a diuretic with frusemide-like activity) had shown that it did not induce a significant change in the serum potassium concentration. In the present study sodium and potassium handling and other metabolic variables have been compared during 16 weeks of therapy with muzolimine and chlorthalidone, a thiazide-like diuretic. During muzolimine treatment, plasma and red cell potassium concentrations remained unchanged, while a significant fall in potassium occured with chlorthalidone. Neither drug affected the activity of sodium-potassium cotransport or sodium-lithium countertransport in red cells in vitro. Muzolimine and chlorthalidone had similar effects on arterial pressure and on the other metabolic variables tested.

    Effect of oxprenolol and metoprolol on serum lipid concentration (1984)

    European journal of clinical pharmacology 26 (1984), S. 331-334

    Notes: Summary The aim of the present study was to evaluate whether a reduction in HDL-cholesterol is peculiar to non cardioselective beta blockers or whether it is also produced by cardioselective beta1-blockers. 16 patients with primary arterial hypertension on a balanced isocaloric diet were given oxprenolol 120 to 240 mg/day or metoprolol 100 to 200 mg/day in a random cross-over study. No significant change was observed after either treatment in fasting blood glucose, serum total cholesterol and triglycerides. HDL-cholesterol concentration was significantly decreased on metoprolol, from 41 to 36 mg/dl (p〈0.05), while oxprenolol did not affect it at all. The difference might depend on intrinsic sympathomimetic activity which is possessed by oxprenolol and which metoprolol lacks.

    Adrenergic system and carbohydrate metabolism. Effects of beta-receptor blockade on insulin secretion and peripheral insulin sensitivity in normoglycaemic patients (1987)
    Springer
    European journal of clinical pharmacology 33 (1987), S. 273-277 
    Details
    ISSN: 1432-1041
    Keywords: beta-adrenoreceptor blockers ; normoglycaemia ; glucose tolerance ; insulin secretion and -sensitivity ; hypertension ; propranolol
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The effects of 3 weeks of treatment with the beta-receptor blocking agent propranolol and a placebo on glucose tolerance, insulin secretion and peripheral insulin sensitivity have been evaluated in 7 normoglycaemic hypertensive patients by an oral glucose tolerance test and the insulin clamp technique. Significant changes in systolic and diastolic blood pressure and heart rate were observed at the end of propranolol treatment, but there were no associated changes in glucose tolerance, insulin secretion or peripheral insulin sensitivity. No difference was observed in glucagon, growth hormone and free fatty acids between propranolol and placebo treatment. The results support the view that the hypothetical pancreatic glucoreceptor, at least in non-acute studies, is not affected by beta blockade. In addition, there was no effect on tissue sensitivity to insulin.

    Effect of nicardipine on insulin secretion, glucose and lipid metabolism in hypertensive, non-insulin dependent diabetics (1989)
    Springer
    European journal of clinical pharmacology 36 (1989), S. 1-4 
    Details
    ISSN: 1432-1041
    Keywords: nicardipine ; insulin ; glucose ; diabetes ; hypertension ; metabolic effects
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Certain acute and chronic metabolic effects of nicardipine have been studied in 20 patients with non-insulin dependent diabetes (NIDD). An intravenous glucose tolerance test (i.v. GTT, glucose 0.33 g/kg as a bolus) and the corresponding insulin response were assessed at the end of a 4 week placebo period, after the first dose and on administration for 12 weeks of nicardipine 20 mg t.i.d. The glucose and insulin responses to the i.v. GTT, evaluated as incremental AUCs, did not change significantly (glucose 30.5 mg/dl·90 min on placebo, 33.1 mg/dl·90 min acutely and 31.4 mg/dl·90 min on chronic administration of nicardipine; insulin 2.08 µU/ml·90 min on placebo, 1.87 µU/ml·90 min acutely and 1.93 µU/ml·90 min after chronic nicardipine). Glucose removal rate (KG) following the i.v. GTT was 0.73%/min on placebo 0.75%/min on acute administration and 0.8%. min−1 with chronic nicardipine. Active treatment produced a significant reduction of blood pressure (from 187/96 mm Hg on placebo to 166/89 mm Hg acutely and 152/83 mm Hg after 12 weeks of nicardipine treatment). It is concluded that the calcium antagonist nicardipine was an effective antihypertensive drug, and that it did not cause deterioration of metabolic control in hypertensive patients with NIDD.
