Effect of chronic treatment with lacidipine or lisinopril on intracellular partitioning of glucose metabolism in type 2 diabetes mellitus.
Antihypertensive treatment is frequently needed in type 2 diabetes. In this study we measured the rates of total, oxidative, and nonoxidative glucose disposal, glycogen synthesis, glycolysis, endogenous glucose production, and lipid oxidation using a 4-h euglycemic (approximately 5 mmol/L) hyperinsulinemic (approximately 300 pmol/L) clamp in combination with a dual glucose tracer infusion ([3-(3)H]- and [U-14C] D-glucose) and indirect calorimetry in 40 nonobese subjects with type 2 diabetes. Subjects were studied twice: after a 4-week run-in period and after a 16-week period of double blind, randomized treatment with 4-6 mg/day lacidipine, a calcium channel blocker (n = 19), or 10-20 mg/day lisinopril, an angiotensin-converting enzyme inhibitor (n = 21). Antihypertensive treatment resulted in a significant increase in total glucose disposal during insulin clamp as well as in basal and insulin-stimulated nonoxidative glucose disposal rates. On the contrary, oxidative glucose disposal was significantly decreased by antihypertensive treatment, mainly in the basal state. The changes in glucose disposal rates were not significantly different in subjects treated with lacidipine and in those treated with lisinopril. The suppression of endogenous glucose production during insulin clamp was significantly greater after lacidipine than after lisinopril. These results suggest that treatment of subjects with type 2 diabetes with either lacidipine or lisinopril has no adverse effect on glucose metabolism. Conversely, both drugs seem to improve insulin sensitivity.

Subacute Toxicity Profile of Lacidipine Nanoformulation in Wistar Rats.
The present study was aimed at investigating the safety of Lacidipine (LCDP) loaded nanostructured lipid carriers (NLCs) in Wistar rats. NLCs were formulated using ultrasound dispersion technique. Animals were orally treated once daily with NLCs containing 0.140 mg, 0.350 mg, and 0.875 mg of LCDP as low, medium, and high dose per kg body weight, respectively, during 28 days along with blank formulation and pure LCDP. Control rats were fed with water. Animals were observed throughout experiment period and their body weight was recorded once weekly. Overnight fasted rats were sacrificed on the 29th day. Study revealed no signs or symptoms of toxicity or morbidity. No significant changes in the body weight were observed between treated and control group. Significant increase in left testis weight and liver weight was observed in male and female rats, respectively. Haematological estimation revealed significant decrease in haemoglobin count in male rats while female rats showed significant increase in granulocyte count. All the serum clinical parameters were within the normal range and no gross histopathological changes were observed. No delayed effect was noted in satellite group. The results indicate that developed LCDP loaded NLCs are safe when administered orally in rats.

Lacidipine prevents the hypertension and renal and cardiac changes induced by high-fructose diet in WKY rats.
Normotensive rats fed a high-fructose diet (HFD) develop hypertriglyceridemia, hyperinsulinemia, and hypertension. The glomerular changes observed in the kidneys of these animals are similar to those observed in diabetic rats. The aim of this study was to evaluate whether lacidipine, a calcium antagonist, could have a protective effect with this animal model. Forty male Wistar-Kyoto (WKY) rats were divided into four groups treated with HFD + placebo; HFD + lacidipine, 0.3 mg/kg/day; HFD + lacidipine, 3 mg/kg/day; or standard diet + placebo for 4 weeks. Urinary excretion of the stable metabolic products of nitric oxide (NO) was determined, because this vasoactive agent has been found to cause hemodynamic changes in the diabetic kidney. Glomerular size was determined by means of morphometric analysis. The results of this study show that lacidipine prevents (a) the HFD-induced increase in blood pressure in a dose-dependent manner; (b) the HFD-induced increase in glomerular size and fibronectin synthesis; and (c) the increase of collagen III synthesis in the heart. The drug had no effect on the increased urinary excretion of the stable metabolic products of NO. These data suggest that lacidipine might be useful in preventing the renal and cardiac damage caused by hypertension and non-insulin-dependent diabetes mellitus.

Therapeutic effects of a calcium antagonist, lacidipine, on stroke-prone spontaneously hypertensive rats with cerebrovascular lesions.
The aim of this study was to investigate the therapeutic effectiveness of lacidipine in stroke-prone spontaneously hypertensive rat (SHRSP) with cerebrovascular lesions in comparison with nicardipine. SHRSP were fed 1% saline as drinking water. After the onset of stroke, saline was replaced with water and each drug was administered orally once a day for 3 weeks. In the drug-untreated group, recurrence of stroke was repeated, deterioration and amelioration of neurological deficits (ND) were repeated, and histological examination and measurement of regional blood flow (rBF) using nonradioactive colored microspheres performed at the end of treatment revealed severe damages and significantly decreased rBF in brain and kidney, respectively. In kidney, not only lacidipine (1 mg/kg) but also nicardipine (30 mg/kg) decreased vascular lesions and ameliorated low-rBF significantly. Both drugs also inhibited the recurrence of stroke completely even at a low dose that did not ameliorate severe hypertension. Neuronal damages and ND in each lacidipine-treated group were ameliorated significantly, whereas those in each nicardipine-treated group were slightly improved. Lacidipine at 1 mg/kg alone ameliorated the cerebral low-rBF significantly even at 24 hr after administration. These results suggest that a long-lasting improvement of low-rBF after stroke may be useful in the treatment of SHRSP with cerebrovascular lesions.

Comparison of effects of ACE inhibition with calcium channel blockade on renal disease in a model combining genetic hypertension and diabetes.
The aim of this study was to compare the renal effects of angiotensin converting enzyme (ACE) inhibition with calcium channel blockade in a model combining genetic hypertension with diabetes. Streptozotocin diabetes was induced in spontaneously hypertensive rats (SHR). The animals were then randomized to receive no treatment, the ACE inhibitor, perindopril, or the dihydropyridine calcium antagonist lacidipine. Body weight, systolic blood pressure, glycemic control, renal function, and albumin excretion rate (AER) were assessed serially over the 32-week study period. At week 32 the animals were killed and glomerular volume was measured. Both antihypertensive regimens significantly reduced systolic blood pressure in diabetic SHR. There was no significant difference in glycemic control, serum creatinine, or glomerular filtration rate among the three groups at week 32. The ACE inhibitor perindopril significantly reduced AER and glomerular hypertrophy over the 32 weeks, whereas the calcium antagonist lacidipine failed to reduce AER or glomerular hypertrophy. Thus, in contrast to the effects of ACE inhibition, calcium channel blockade with lacidipine, despite significantly reducing blood pressure, failed to reduce renal injury in this model. These results support the hypothesis that antihypertensive regimens may differ in their capacity to protect the diabetic kidney, despite similar effects on systemic blood pressure.

Lacidipine: prevention of vascular damage induced by hypertension.
Lacidipine is a long-lasting 1,4-dihydropyridine calcium antagonist that has been reported to protect salt-loaded Dahl-S rats from vascular damage and accelerated mortality when it is administered prophylactically at 0.1 and 0.3 mg/kg p.o. once a day (equivalent to the recommended dose in humans). The aim of this study was to investigate the vasoprotective properties of lacidipine in Dahl-S rats that had already developed sustained hypertension after 4 weeks of a salt-rich diet. Although none of the dosages of lacidipine (0.3, 1, and 3 mg/kg) reduced the elevated values of blood pressure, an almost complete protection from mortality was obtained. Moreover, lacidipine dose-dependently inhibited the development of macroscopic and microscopic alterations in the distal branches of mesenteric arteries and in the brain. A clear regression of vascular damage and cardiac hypertrophy was observed at the highest dose tested (3 mg/kg). These findings further support the assumption that the protective properties of lacidipine are not restricted to a reduction in blood pressure.
