Mean health service costs between the period of randomisation and discharge for mother and infant were 1254.86 pound sterling in the IMN group and 1242.88 pound sterling in the placebo group, generating a mean cost difference of 11.98 pound sterling (bootstrap mean cost difference 12.86 pound sterling; 95%CI: -106.79 pound sterling, 129.39 pound sterling) that was not statistically significant (P = 0.842). The incremental cost per hour prevented from hospital admission to delivery was 7.53 pound sterling. At the notional willingness to pay threshold of 100 pound sterling per hour prevented from hospital admission to delivery, the probability that IMN is cost-effective was estimated at 0.67. This translated into a mean net monetary benefit of 98.13 pound sterling for each woman given IMN.

Nicorandil (SG-75) is a new organic nitrate with pronounced vasodilator properties. We studied whether nicorandil, in analogy to other nitrovasodilatators, exerted its relaxing effects on vascular smooth muscle by stimulating guanylate cyclase, and whether this effect was susceptible to tolerance development. Dose-response curves for the relaxing and cyclic guanosine monophosphate (cGMP) increasing effects of nicorandil were obtained in isolated strips of bovine coronary arteries and compared with those of other nitrovasodilatators. It was found that nicorandil dose-dependently relaxed the strips precontracted with 26.7 mM K+ and that this effect was closely associated with increases in cGMP levels (measured by RIA under various conditions). The correlation between relaxation and rises in cGMP was steeper than with other nitrovasodilatators, suggesting that nicorandil, in addition to its cGMP-mediated effect, also relaxed vascular smooth muscle by a cGMP independent mechanism. In contrast to nitroglycerin (NG), nicorandil caused little development of tolerance or cross-tolerance toward ISDN or IS-5-MN when tested after preincubation of the strips toward the respective substance. Pretreatment with N-acetylcysteine during the preincubation period prevented tolerance towards nicorandil. The results indicate that the relaxant effects of nicorandil consist of a larger cGMP-mediated component and a smaller one which is independent of this nucleotide.

This study was designed to assess the efficacy of oral nifedipine as compared to oral isosorbide-5-mononitrate in the prevention of spontaneous and induced vasospastic myocardial ischaemia. Twenty-one patients admitted to the Coronary Care Unit as a result of angina at rest underwent both Holter monitoring and an echo-ergonovine test during placebo and following either isosorbide-5-mononitrate or nifedipine according to a double-blind randomized trial. Both drugs caused a statistically significant reduction in spontaneous (87% and 95%, respectively) and induced ischaemic attacks (66% and 75%, respectively). No significant difference was found between the two drugs.

Isosorbide dinitrate inactivated E1 and E2 isozymes of human aldehyde dehydrogenase (EC 1.2.1.3), abolishing both dehydrogenase and esterase activities. NAD promoted, whereas chloral and NAD protected the enzyme from inactivation. The inactivation was irreversible upon dialysis and occurred without incorporation of the 14C-labeled isosorbide dinitrate. Inactivation was associated with formation of products, isosorbide-2-mononitrate and isosorbide-5-mononitrate. At 25 degrees C there were two pathways of product formation: a fast pathway, sensitive to aldehyde dehydrogenase inhibitors, and a slower pathway insensitive to inhibitors. The fast product formation and inactivation occurred simultaneously, and both were inhibited by chloral and by the irreversible active site-directed inhibitor bromoacetophenone. At 0 degree C the slow product formation was abolished, allowing study of the enzyme catalyzed reaction. The inactivation of the E1 isozyme at 0 degree C occurred in a single turnover that accounted for 80% of catalytic activity loss with isosorbide-2-mononitrate being the major product. No nitrate was ever detected; at 25 degrees C, nitrite was detected but in less than stoichiometric amounts. The mononitrates were also substrates and inactivators of aldehyde dehydrogenase. Isosorbide-2-mononitrate had the lowest K(i) and k3 values for the E1 isozyme when compared with that of the other two nitrate esters of isosorbide. Reversibility of inactivation by 2-mercaptoethanol suggested involvement of enzyme sulfhydryls. The inactivation appears to be mechanism-based and involves the esterase function of aldehyde dehydrogenase.

Fifty-eight males with chronic stable angina (NYHA class II-III) with evidence of provocable ischemia on treadmill exercise test received Terminalia arjuna (500 mg 8 hourly), isosorbide mononitrate (40 mg/daily) or a matching placebo for one week each, separated by a wash-out period of at least three days in a randomized, double-blind, crossover design. They underwent clinical, biochemical and treadmill exercise evaluation at the end of each therapy which were compared during the three therapy periods. Terminalia arjuna therapy was associated with significant decrease in the frequency of angina and need for isosorbide dinitrate (5.69+/-6.91 mg/week v. 18.22+/-9.29 mg/week during placebo therapy, p<0.005). The treadmill exercise test parameters improved significantly during therapy with Terminalia arjuna compared to those with placebo. The total duration of exercise increased (6.14+/-2.51 min v. 4.76+/-2.38 min, p<0.005), maximal ST depression during the longest equivalent stages of submaximal exercise decreased (1.41+/-0.55 mm v. 2.21+/-0.56 mm, p<0.005), time to recovery decreased (6.49+/-2.37 min v. 9.27+/-3.39 min, p<0.005) and higher double products were achieved (25.75+/-4.81x10(3) v. 23.11+/-4.83x10(3), p<0.005) during Terminalia arjuna therapy. Similar improvements in clinical and treadmill exercise test parameters were observed with isosorbide mononitrate compared to placebo therapy. No significant differences were observed in clinical or treadmill exercise test parameters when Terminalia arjuna and isosorbide mononitrate therapies were compared. No significant untoward effects were reported during Terminalia arjuna therapy.

Chronic therapy with either ISMN or TD-NTG is associated with development of vascular tolerance. Despite the induction of vascular tolerance, platelet responsiveness to NTG and SNP remains unaffected. Therefore, development of vascular tolerance is unlikely to compromise the anti-aggregatory effects of organic nitrates, or those of endogenous NO.

A total of 19 healthy volunteers were randomized in a double-blind fashion to therapy with IS-5-MN (120 mg once daily) or placebo. After 7 days of treatment, forearm blood flow responses to acetylcholine (Ach; 7.5, 15, and 30 microg/min) and N-monomethyl-L-arginine (L-NMMA; 1, 2, and 4 mumol/min) were measured. In a separate study, after 7 days of therapy with IS-5-MN 120 mg once daily, the responses to Ach were assessed during intra-arterial coinfusion of vitamin C (24 mg/min) or saline.

Isosorbide 5-mononitrate is an active metabolite of isosorbide dinitrate and possesses many theoretical advantages over its parent drug. However, the development of partial tolerance has been demonstrated when the drug is given 12 hourly or 8 hourly. We have therefore evaluated the acute and sustained (2 weeks) effects of isosorbide-5-mononitrate 40 mg given twice daily (08.00 h and 14.00 h, allowing an 18-h dose-free period) in 19 patients with stable chronic angina, using computerized exercise testing and a placebo-controlled, double-blind, randomized trial protocol. There were two phases of 2 weeks each in which patients received placebo or active isosorbide-5-mononitrate. Acute testing was performed 2 h after the first dose and chronic testing 2 h after the morning dose on Day 14. Acute testing showed an increase in exercise time from a mean (SD) of 6.7 (2.2) min to 10.1 (2.95) min (P less than 0.01) after a single dose of isosorbide-5-mononitrate 40 mg. The time to 1 mm of ST depression, and rest and peak exercise heart rates increased significantly during acute testing with isosorbide-5-mononitrate; resting and peak exercise systolic blood pressures fell significantly. Due to drop outs cross-over analysis was performed on 11 patients who completed both chronic phases and 13 patients were assessed for the comparison of acute isosorbide-5-mononitrate with chronic isosorbide-5-mononitrate. After 2 weeks of therapy exercise time did not show a sustained increase 8.01 (2.14) min chronic placebo to 8.58 (1.93) min chronic isosorbide-5-mononitrate.(ABSTRACT TRUNCATED AT 250 WORDS)

After infusion of isosorbide mononitrate there were significant reduction in mean right atrial pressure no mean pulmonary artery pressure (< 0.0001), left ventricular and diastolic pressure (p < 0.004), left ventricular systolic pressure (p < 0.002), maximum (p < 0.002) and mean (p < 0.008) aortic pressure, and left ventricular systolic volume (p < 0.004), as well as significant increase in the left ventricular ejection fraction (p < 0.001) and mean velocity of circunferential fibers shortening (p < 0.001). There was no significant modification of minimum aortic pressure, heart rate, cardiac output nor of left ventricular and diastolic volume. With respect of segmental motility of the left ventricle after medication, 38 kypokinetic segments normalized their motility, 4 akinetic segments remained intact, and of the 21 dyskinetic segments, 6 normalized, 8 became hypokinetic and 7 remained dyskinetic.

We tested whether the known cytochrome c oxidase (COX) inhibition by nitric oxide (NO) could be quantified by VO(2) kinetics during constant load supra-Anaerobic Threshold (AT) exercises in healthy trained or untrained subjects following aerobic training or nitrate administration. In cycle ergometer constant load exercises supra-AT, identified in previous incremental tests, VO(2) kinetics describe a double exponential curve, one rapid and one appreciably slower, allowing the area between them to be calculate in O(2) l. After training, with increased NO availability, this area decreases in inverse ratio to treatment efficacy. In fact, in 11 healthy subjects after aerobic training for 6-7 weeks, area was decreased on average by 51 %. In 11 untrained subjects, following the assumption of an NO donor, 20 mg isosorbide 5 mononitrate, area was decreased on average by 53 %. In conclusion, supra-AT VO(2) kinetics in constant load exercises permit the quantification of the inhibitory effect NO-dependent on COX after either physical training or nitrate assumption.

GSTM1 null individuals showed significantly lower systolic BP (SBP) and diastolic BP (DBP), and higher degree of decreases in SBP (ΔSBP) and DBP (ΔDBP) after IS-5-MN administration. GSTM1 null individuals showed significantly decreased IS-5-MN area under the plasma concentration-time curve than GSTM1 wild-type individuals (P<0.05). Plasma concentration of CGRP was increased significantly at 0.5 (P<0.01), 1 (P<0.05), and 2 h (P<0.05) after IS-5-MN administration in GSTM1 null individuals but not wild-type individuals. GSTM1 null individuals also showed significantly higher degree of percentage increase in the plasma concentration of CGRP than GSTM1 wild-type individuals at 1 h after IS-5-MN administration (P<0.05). IS-5-MN upregulated CGRP I and CGRP II mRNA expressions in cultured peripheral blood mononuclear cells, and the IS-5-MN-induced CGRP II mRNA expression was inhibited by GSTs inhibitor, ethacrynic acid. No difference in the IS-5-MN response was observed between ALDH2 genotypes.

In a group of 13 patients with severe heart failure, both forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) significantly improved after intensive medical therapy (FVC: from 77 +/- 17 to 92 +/- 20%, p < 0.001; FEV1: from 65 +/- 15 to 81 +/- 15%, p < 0.001) in the absence of change in M-mode echo cardiac dimension and left ventricular systolic function; on the other hand, a change of indices of left ventricular filling by Doppler transmitral flow was documented (E/A ratio: from 3.6 +/- 1.2 to 1.65 +/- 1.5, p < 0.01; early filling deceleration time: from 94 +/- 39 to 178 +/- 78 ms, p < 0.01), indicating a reduction of pulmonary capillary pressure; this probably positively affected pulmonary interstitial edema and bronchial wall congestion, thus enhancing pulmonary function.

After a median follow up of 23 months, recurrent upper gastrointestinal bleeding developed in 51% in the Medication group and 38% in the Combined group (P = 0.21). Recurrent bleeding from esophageal varices occurred in 26 patients (43%) in the Medication group and in 16 patients (26%) in the Combined group (P = 0.07). Recurrent bleeding from gastroesophageal varices occurred in 48% of Medication group and 28% of Combined group (P = 0.05). The frequency of adverse effects and mortality rates were similar between both groups (P = 0.28).

An endothelin urinary hyperexcretion, which is not counterbalanced by an adequate increase in cGMP biosynthesis, was previously detected in some patients with IgA Nephropathy (IgAN). Since this imbalance might potentiate local ET1-mediated hemodynamics effects, 9 IgAN patients with an increased (> or = 0.1) urinary ET1/cGMP ratio (group 1) and 5 IgAN patients with comparable renal function and reduced ET1/cGMP ratio (group 2) were given standard doses of isosorbide 5 mononitrate (as a nitric oxide source). Blood nitric oxide (NO) levels, as detected by electron paramagnetic resonance, significantly increased after isosorbide administration (p < 0.01) and decreased after drug discontinuation in both groups. Nitric oxide levels were significantly related with those of the effective renal plasma flow (p < 0.02), but not with the glomerular filtration rate. Proteinuria levels significantly decreased after drug administration (p < 0.009) in group 1 and returned to baseline levels thereafter, except two cases showing persisting low levels. Values of filtration fraction in the same group decreased after iso5M administration (p < 0.02 compared to basal levels). These results may possibly be related to the counterbalancing effects of nitric oxide on endothelin-mediated mesangial contraction.

Injection of large volumes of samples in solvents other than mobile phase composition has been proved for some less hydrophobic compounds. Thus, the retention behavior of several compounds of pharmaceutical interest (isosorbide-2-nitrate, isosorbide-5-nitrate, tropicamide, pentoxifylline, and methyl p-hydroxybenzoate) was studied by using different hydrophobic solvents (n-hexane, n-heptane, or i-octane) as sample solvents. Two types of stationary phases were used: octyl and octadecyl modified silica (both of Zorbax Eclipse type). The experiments showed a linear dependence between capacity factor of each solute and sample injection volume, up to maximum volume values of about 680 microL for C8 stationary phase and 580 microL for C18 stationary phase, when the solutes are no longer retained in stationary phase. Injection of large volumes of these hydrophobic solvents is thus possible in RP-LC with a gradual reduction of retention and peak efficiency. Two major conditions are however necessary in order to apply such an injection approach: the solutes must have a proper solubility in hydrophobic solvents and meanwhile they have to be less hydrophobic than the sample solvent in order to avoid competition with solvent molecules in partitioning between mobile and stationary phases.

Safety has been assessed in a total of 1680 subjects who were treated with nicorandil, with 458 patient years of exposure to treatment. Adverse events usually occurred early in the course of treatment. After 30 days of treatment, fewer than 10% of patients reported adverse events. At the recommended doses, the main side effects were limited to headaches. Nearly all episodes of headache were experienced during the first days of nicorandil treatment and were responsible for most of the study withdrawals because of clinical non-acceptability. The incidence can be diminished by a progressive titration. In comparative trials with anti-anginal agents, such as propranolol, diltiazem, nifedipine, ISDN and isosorbide 5 mononitrate, the overall incidence of adverse events was not significantly different between nicorandil and the reference drug. Side-effect distribution was comparable between nicorandil (32%) and diltiazem (30%). Nicorandil can be safely combined with other anti-anginal drugs. Furthermore, due to its favourable pharmacokinetics, nicorandil is less likely to have interactions when combined with another therapeutic agent. Nearly one-third of the patients enrolled in the nicorandil clinical programme were 65 years old or older. Age-specific side-effects were not identified, and overall, the incidence of the most frequent adverse events in the elderly was similar. There is no evidence that nicorandil induces proarrhythmia, exacerbation of myocardial ischaemia or abrupt withdrawal syndrome. With the progressive titration scheme, no symptomatic decrease in blood pressure was recorded when nicorandil was administered in the range of 10-80 mg.day-1. Heart rate was not significantly affected in the same dose range.(ABSTRACT TRUNCATED AT 250 WORDS)

The haemodynamic effects of 10 mg of isosorbide-5-mononitrate (IS-5-MN) and 10 mg of isosorbide dinitrate (ISDN), administered in intravenous injection, were compared in 16 patients with acute myocardial infarction. The study, using the balloon thermodilution catheter, took 4 hours to complete. Both drugs produced a decrease in pulmonary and peripheral arterial pressure, cardiac index, stroke and stroke work indexes; the effect was present immediately after administration to reach a maximum 3-15 minutes later, after which the values gradually returned to baseline levels. While IS-5-MN resulted in an increase in peripheral arterial resistance, heart rate rose briefly following the administration of ISDN. After buy imdur online IS-5-MN, pulmonary diastolic pressure decreased by 15% and peripheral arterial pressure by 5%, and stroke work index by 12%; the magnitude of decrease was double following the administration of ISDN (30%, 15% and 23%, respectively). The decrease in cardiac and stroke indexes was likewise less pronounced after IS-5-MN than after ISDN, the difference, however, was not statistically significant. Duration of the haemodynamic effect of both drugs was about the same--approximately 3 hours.

Dogs were buy imdur online subjected to various durations of ventricular tachypacing (VTP, 220 to 240 bpm) in the presence or absence of oral enalapril 2 mg. kg(-1). d(-1). VTP for 5 weeks induced CHF, local atrial conduction slowing, and interstitial fibrosis and prolonged atrial burst pacing-induced AF. Atrial angiotensin II concentrations and MAPK expression were increased by tachypacing, with substantial changes in phosphorylated forms of c-Jun N-terminal kinase (JNK), extracellular signal-regulated kinase (ERK), and p38-kinase. Enalapril significantly reduced tachypacing-induced changes in atrial angiotensin II concentrations and ERK expression. Enalapril also attenuated the effects of CHF on atrial conduction (conduction heterogeneity index reduced from 3.1+/-0.4 to 1.9+/-0.2 ms/mm, P<0.05), atrial fibrosis (from 11.9+/-1.1% to 7.5+/-0.4%, P<0.01), and mean AF duration (from 651+/-164 to 218+/-75 seconds, P<0.05). Vasodilator therapy of a separate group of VTP dogs with hydralazine and isosorbide mononitrate did not alter CHF-induced fibrosis or AF promotion.

The possibility of maintaining preload reduction and enhancement of exercise tolerance during an interval treatment with 100 mg/day of slow-release isosorbide-5-mononitrate (IS-5-MN) was investigated in 12 patients (aged 57 +/- 5.0 years) with angiographically confirmed coronary artery disease and chronic stable angina pectoris. The effects of a single dose (acute test) were compared with those following an 8-day (chronic) regimen of mononitrate administration. Two hours after administration of 100 mg sustained-release IS-5-MN, mean resting pulmonary artery pressure (PAP), measured with a Swan-Ganz catheter, was reduced by 32% (p less than 0.001) and at submaximal exercise level (50 W, 3 min) by 37% (p less than 0.001). At individually highest comparable work loads mean PAP was reduced by 37% (p less than 0.001), and at maximal work load the PAP reduction was 14% (p less than 0.05). At the end of 1 week of therapy with sustained-release IS-5-MN a slight, clinically irrelevant reduction of hemodynamic effect was recorded. Work capacity increased after 1 h by 79% (264 +/- 154 vs. 472 +/- 180 W x min, p less than 0.01), still significantly above base-line 10 h after nitrate administration. No difference from baseline was demonstrable 24 h after medication. During interval therapy the improved work capacity was fully maintained (chronic, 1 h: 280 +/- 119 vs. 532 +/- 160 W x min, p less than 0.001). There buy imdur online was no significant difference between the plasma IS-5-MN levels at acute and chronic therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

However, the levels of its metabolites, 5-isosorbide mononitrate (5-ISMN) and 2-isosorbide mononitrate (2-ISMN), were markedly lower in ES rats than in the control rats. On the other hand, urine ISDN and 2-ISMN excretion rates were lower in ES rats than in the control rats. These observations suggest that the pharmacokinetics of ISDN administered s.c. is influenced by emotional stress such as foot shock.

The influence of isosorbide mononitrate on skin blood flow in the pulp of finger by means of laser-Doppler flowmetry was evaluated in 19 women with Raynaud's syndrome. Skin blood flow changes were measured after cooling buy imdur online the hand. Isosorbide mononitrate decreased the influence of cooling on skin blood flow in the pulp of finger. This finding supports the theory that endothelial dysfunction is one of the reasons of Raynaud's syndrome. We suppose that application of isosorbide mononitrate should be useful in prevention and the treatment of Raynaud's phenomenon attacks.

Among 1023 patients in 12 trials comparing EBL with beta-blockers for primary prevention, there was no significant difference in gastrointestinal bleeding (RR 0.79 [95% CI 0.61 to 1.02]), all-cause deaths (RR 1.06 [95% CI 0.86 to 1.30]) or bleeding-related deaths (RR 0.66 [95% CI 0.38 to 1.16]). There was a reduced trend toward significance in variceal bleeding with EBL compared with betablockers (RR 0.72 [95% CI 0.54 to 0.96]). However, variceal bleeding was not significantly different between the two groups in high-quality trials (RR 0.84 [95% CI 0.60 to 1.17]). Among 687 patients from six trials comparing buy imdur online EBL with beta-blockers plus isosorbide mononitrate for secondary prevention, there was no effect on either gastrointestinal bleeding (RR 0.95 [95% CI 0.65 to 1.40]) or variceal bleeding (RR 0.89 [95% CI 0.53 to 1.49]). The risk for all-cause deaths in the EBL group was significantly higher than in the medical group (RR 1.25 [95% CI 1.01 to 1.55]); however, the rate of bleeding related deaths was unaffected (RR 1.16 [95% CI 0.68 to 1.97]).

Previous studies have shown that NCX 6550 (NCX), a nitric oxide (NO)-donating pravastatin, induces anti-inflammatory effects in murine macrophage cell lines. Here, we have studied its activity in human monocyte/macrophages, by investigating cytokine release, NF-κB translocation and peroxisome proliferator-activated receptor γ (PPARγ) expression and function. For comparison, pravastatin, isosorbide-5-mononitrate (ISMN), sodium nitroprusside (SNP) and the PPARγ ligand 15-deoxy-Δ(12,14)-prostaglandin J(2) (PGJ) were also tested. Monocytes and macrophages (MDM: monocyte-derived macrophages) were isolated from healthy donors; cytokine release was measured by ELISA, NF-κB by electrophoretic mobility shift assay and PPARγ by Western blot and Real-Time PCR. NCX (1 nM-50 μM) dose-dependently inhibited phorbol 12-myristate 13-acetate (PMA)-induced TNF-α release from monocytes (IC(50)=240 nM) and MDM (IC(50)=52 nM). At 50 μM, it was more effective than pravastatin, ISMN and SNP (P<0.05), but less efficient than PGJ. Similar results were obtained for IL-6. Likewise, NCX was more effective than pravastatin and the other NO donors in inhibiting PMA-induced NF-κB translocation in both cell types, and, at the highest concentration, significantly (P<0.05) enhanced PPARγ protein expression in monocytes. We conclude that NCX 6550 exerts a significant anti-inflammatory activity in human monocyte/macrophages, that is also contributed by its NO donating properties, as the effects exerted by NCX are significantly higher than those evoked by pravastatin in many experimental assays. These Amaryl 50 Mg data further indicate that the incorporation of a NO-donating moiety into a statin structure confers pharmacological properties which may translate into useful therapeutic benefits.

Addition of sodium nitroprusside (NaNTP), a nitric oxide (NO) donor to peritoneal solution could enlarge the effective peritoneal surface area and the peritoneal pore size. This would Anafranil 20 Mg be leading to increased clearance of all solutes. Generalized clinical usage of NaNTP in CAPD patients however is not practical because it has a very short half-life and needs a specific route of administration. Organic nitrate, another NO donor, has a longer half-life and could be more easily absorbed via many routes.

Two double-blind, placebo-controlled, randomized Bactrim Dosing , two-way crossover trials were undertaken. Sixteen male patients received oral ISMN (20 mg twice a day) for five to seven days before their dose of sildenafil or placebo and continued receiving ISMN daily until administration of the alternate drug seven days later. For the second study, 15 male patients received sublingual GTN (500 microg) 1 h after sildenafil or placebo on each of two study days, which were seven days apart. Sitting or standing BP was measured before and for 6 h after the administration of the study drug.

Nitroglycerin and isosorbide dinitrate (ISDN), the most commonly used nitrate vasodilators, have been shown to possess antiplatelet properties. It has also been shown, interestingly, that their inhibition of aggregation Glucotrol Xl Reviews (mostly upon ADP and adrenaline) occurs in vivo at concentrations 1-2 log orders lower than in vitro, and in the full therapeutic range. Many different hypotheses may explain such an in vivo/in vitro difference: 1) that nitrates induce prostacyclin synthesis; 2) that they synergize prostacyclin; 3) that they give rise to more active in vivo metabolites; 4) that some other requirement for their action, such as the availability of reducing thiols, may be a limiting factor in the in vitro setting. The discrimination among such hypotheses should contribute new insights into nitrate action at the platelet level. On the basis of experiments on cultured endothelial cells and vascular fragments, we had previously concluded against prostacyclin induction by nitrates. On the other hand, ISDN may decrease the IC50 for prostacyclin in aggregation by suprathreshold doses of various aggregating agents, and therefore, be synergistic with this endogenous antiplatelet substance. Compared to ISDN, the two longer-lived metabolites isosorbide-2- and isosorbide-5-mononitrates (IS-2-MN, IS-5-MN) appear remarkably different in terms of antiplatelet potency in vitro (minimum effective concentrations 10(-7)-10(-6)M for IS-2-MN, 10(-4)M for IS-5-MN, for ADP-and adrenaline-induced aggregation and thromboxane (TX) B2 production).(ABSTRACT TRUNCATED AT 250 WORDS)

In the prevention of variceal rebleeding, it is already established that hemodynamic response to drug treatment (decrease in hepatic venous pressure gradient [HVPG] to 12 mm Hg or by >20%) is predictive of clinical effectiveness. In primary prophylaxis very few clinical data are available. We assessed the role of the hemodynamic response to beta-blockers or beta-blockers plus nitrates in predicting clinical efficacy of prophylaxis. A total of 49 cirrhotic patients with varices at risk of bleeding, without prior variceal bleeding, were investigated by hepatic vein catheterization before and after 1 to 3 months of chronic treatment with nadolol or nadolol plus isosorbide mononitrate, and were followed during treatment for up to 5 years. A total of 30 patients (61%) were good hemodynamic responders, and among them in 12 (24%) HVPG was Lanoxin Tablet Composition reaching an HVPG of 12 mm Hg or less during treatment had variceal bleeding during follow-up. Cox's regression analysis showed that poor hemodynamic response was the main factor predicting bleeding (beta = 1.91; SE(beta) = 0.80; P =.01). During follow-up 11 patients died of hepatic causes. Survival was related to Child-Pugh class and to initial value of HVPG, according to Cox's analysis. In conclusion, the assessment of hemodynamic response to drugs in terms of HVPG is the best predictor of efficacy of prophylaxis of variceal bleeding in patients treated with beta-blockers or beta-blockers plus nitrates.

The effect of a controlled-release formulation of isosorbide-5-mononitrate (IS-5-MN) was studied in patients with coronary heart disease (CHD), with the aim of comparing the acute effect with that after chronic administration on parameters of ischemia. To determine whether any tolerance developed, several aspects of ischemia were observed: ECG signs, clinical parameters, and left ventricular function. Fifteen patients with angiographically proven CHD were examined with 12-lead exercise ECG before, 2 h and 4 h after the first dose and after 10 days of therapy with 60 mg IS-5-MN (Coleb-Duriles) once daily. After 7 days, three radionuclide ventriculographies were performed: control, 2 h after nitrate and 2 h after 75 mg gallopamil. Plasma concentrations of IS-5-MN were measured before every exercise test. The results showed a reduction of total ST-segment depression from 0.59 mV to 0.29 mV after 2 h (NS) and 4 h (P less than 0.05) on the 1st day and from 0.48 mV to 0.32 mV (P less than 0.05) and 0.31 mV (NS) after 10 days. The severity of angina pectoris was diminished by about 50%. The effect on exercise duration and time to ST-segment depression by more than 0.1 mV remained unchanged after 10 days, whereas the effect on blood pressure, heart rate and time to onset of angina was attenuated. The mean decrease in ejection fraction ( Cipro Dosage Forms EF) from rest to exercise was reduced from--5.9% to -1.9% (P less than 0.05) after nitrate, while an increase of +1.4% was seen after gallopamil (P less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
