Efficacy and safety of triple therapy (fluvastatin-bezafibrate-cholestyramine) for severe familial hypercholesterolemia.

Familial hypercholesterolemia carries a markedly increased risk of coronary artery disease. Reduction of plasma low density lipoprotein cholesterol (LDL-C) levels to the normal range may prevent premature atherosclerosis and usually requires a combination of cholesterol-lowering drugs such as 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors plus resins or fibrates. The current, 60-week, open-label investigation involved 22 patients whose plasma LDL-C had not reached the target level for prevention of coronary artery disease in 3 previous studies using fluvastatin alone and in combination with other cholesterol-lowering medications. At the beginning of the current study, patients were stabilized on fluvastatin monotherapy at 40 mg/day. After 6 weeks, the daily treatment changed to a combination of fluvastatin 40 mg/day in the evening and bezafibrate 400 mg/day in the morning. After a further 6 weeks, a lunchtime dose of cholestyramine 8 g/day was added, to form triple cholesterol-lowering therapy. Efficacy was determined by plasma lipid/lipoprotein analysis. Baseline levels were assessed after 4 weeks of placebo treatment, prior to active treatment, in the first fluvastatin study. Safety analyses included liver and renal function tests, creatine phosphokinase levels and blood counts. Compliance was determined by counting the fluvastatin capsules, bezafibrate tablets, and cholestyramine sachets returned by the patients at each visit. The triple-drug combination used in this study was more effective than the double therapy and resulted in stabilization of the LDL-C:high density lipoprotein cholesterol (HDL-C) ratio, at a reduction from baseline ranging from -40.4 to -52.5%.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of atorvastatin and bezafibrate on plasma levels of C-reactive protein in combined (mixed) hyperlipidemia.

C-reactive protein (CRP) is a non-specific but sensitive marker of underlying systemic inflammation. High CRP plasma levels correlate with risk for future cardiovascular events. The present study evaluated the effects of atorvastatin (10-40 mg) and bezafibrate (400 mg) on CRP concentrations after 6 and 12 months of treatment in 103 patients with combined (mixed) hyperlipidemia. The number of cardiovascular risk factors present in a given patient was associated with baseline CRP levels. After 6 months and 1 year, atorvastatin treatment was associated with significant (P<0.001) decreases from baseline of CRP concentrations by 29 and 43%, respectively, while bezafibrate-treated patients showed non-significant reductions of 2.3 and 14.6%, respectively (P=0.056 and 0.005 for the respective differences between the two treatment arms at 6 months and 1 year). The magnitude of change in CRP after 1 year was directly related to baseline CRP levels. Covariance analysis showed that CRP decreases in the atorvastatin group were unrelated to total cholesterol and LDL cholesterol reductions; however, they were directly related to triglyceride changes (r=0.28, P=0.047) and inversely related to HDL cholesterol changes (r=-0.28, P=0.045). A model including baseline CRP values and treatment effect showed that atorvastatin use was a significant predictor of change in CRP levels over time (beta=0.82, P=0.023). These results suggest a potential anti-atherosclerotic additional benefit of atorvastatin in patients at a risk of cardiovascular disease.

Postprandial concentrations and distribution of apo C-III in type 2 diabetic patients. Effect Of bezafibrate treatment.

Apo C-III plays a key role in the metabolism of triglyceride-rich lipoproteins. It has recently been implicated as a potential determinant of the triglyceride (TG) lowering effect of fibrates, which down-regulate its expression. This hypothesis has been explored in ten moderately hypertriglyceridemic (TG 4.50+/-2.40 mmol/l) male type 2 diabetic patients tested with a lipid load before and after 4 weeks of treatment with 400 mg bezafibrate daily. Treatment lowered apo C-III concentrations by 20%, mainly in VLDL. Postprandially, apo C-III was transferred to chylomicrons in proportion to their TG content exclusively from HDL. VLDL retained their apo C-III and the apo C-III:TG ratio decreased as TG contents increased. At the end of the absorptive period (8 h) HDL did not recover the totality of their apo C-III (net loss 19 and 28% respectively before and after treatment, P<0.0001 for time effect). Bezafibrate lowered apo E by 33% (P<0.03). The apo C-III:apo E ratio did not vary significantly under treatment but underwent a postprandial decrease: 13% before and 18% (P=0.01) after treatment. These results indicate that repression of apo C-III expression and lowering of the apo C-III:E ratio are not likely mechanisms for the lipid-lowering effects of fibrates in type 2 diabetic patients. The potent effects on postprandial lipemia are suggestive of an apo C-III-independent stimulation of lipolysis.

Effect of bezafibrate on hypercoagulability assessed by fluorogenic prothrombin time in hyperlipidemic patients with non-insulin-dependent diabetes mellitus.

We investigated the usefulness of the fluorogenic prothrombin time (FPT) for detection of hypercoagulability and its association with hyperlipidemia in 19 patients with non-insulin-dependent diabetes mellitus (NIDDM) and 10 healthy control subjects, compared with plasma levels of fibrinogen, plasminogen activator inhibitor-1 (PAI-1) and D-dimer. We also evaluated the effect of bezafibrate on hypercoagulability in 10 hyperlipidemic NIDDM patients. The plasma levels of FPT and fibrinogen were significantly higher in hyperlipidemic NIDDM patients than in normolipidemic NIDDM patients and controls. Plasma levels of PAI-1 and D-dimer were significantly higher in normolipidemic and hyperlipidemic NIDDM patients compared with controls. The FPT was correlated with the HbA1c, the body mass index, and levels of total cholesterol, fibrinogen and PAI-1. Six-months therapy with bezafibrate reduced the levels of FPT, triglycerides and basal insulin, but did not alter levels of fibrinogen, PAI-1 and D-dimer. Our results showed that the FPT was useful for detection of hypercoagulability and evaluation of the effect of drugs. The increased FPT in patients with NIDDM suggested that hypercoagulability was present in association with hyperlipidemia.

Determination of bezafibrate, ciprofibrate and fenofibric acid in human plasma by high-performance liquid chromatography.

A selective high-performance liquid chromatographic method to assess either bezafibrate, ciprofibrate or fenofibric acid plasma levels is described. Drugs are extracted with diethyl ether, after acidification with HCL. An isocratic acetonitrile 0.02 M H3PO4 (55:45) mobile phase, a C18 microns) column and UV detection are used. The LOQ found was 0.25 microgram/ml for the three fibrates. Intra- and inter-assay accuracy ranges were 90-107% and 82-111%: 96-115% and 94-107%: 94-114% and 94-126% for bezafibrate, ciprofibrate and fenofibric acid, respectively. Intra- and inter-assay precision (C.V.% ranges) were 1.72-3.06% and 2.66-7.67%: 1.88-4.64% and 0.62-2.99%: 1.26-4.69% and 3.56-7.17% for the three fibrates studied. Its sensitivity, accuracy and precision make it a useful tool for monitoring plasma levels of these drugs in a clinical setting and for research purposes.

Spin equilibria in human methemoglobin: effects of bezafibrate and inositol hexaphosphate as measured by susceptometry and visible spectroscopy.

The effects of inositol hexaphosphate (IHP) and a second allosteric effector, bezafibrate, on the spin-state equilibria of the mixed-spin derivatives of ferric human hemoglobin A are examined. Changes in spin-state equilibrium are monitored by measuring absorption spectra in the visible region (460-700 nm) as well as by direct measurements of magnetic susceptibility by means of a superconducting fluxmeter. The addition of IHP at pH 6.5 results in a measurable shift in the spin equilibria of these derivatives toward higher spin. However, the addition of bezafibrate in the presence of IHP results in still larger shifts toward the high-spin form. The changes in the free energies of the spin-state equilibria resulting from the combination of these two effectors are similar in magnitude to that which results from the R-state to T-state transition in carp hemoglobin.

Physicochemical changes in HDL3 after bezafibrate treatment: influence on free cholesterol efflux from human fibroblasts.

The effects of bezafibrate, a well-used fibric acid hypolipidemic agent, were investigated in 10 moderately hypertriglyceridemic patients. The aim was to quantify the physico-chemical modifications to high-density lipoprotein subfraction 3 (HDL3) induced by treatment and to assess, in vitro, the alterations in its principal physiological function, the efflux of intracellular free cholesterol. Treatment (200 mg/thrice/d for 3 months) resulted in a 48% decrease in plasma triglycerides, with an increase in the HDL cholesterol, due mainly to an increase in the HDL3 (P < 0.01). Composition analysis of HDL3 indicated an increase in cholesterol esters (P < 0.01), free cholesterol (P < 0.01), and phospholipids (P < 0.01), coupled with a decrease in the protein content of the molecule compared with pretreatment values. Fluorescence anisotropy at 24 degrees C was significantly higher post-treatment than pretreatment (P < 0.01). The cholesterol effluxing capacity of pretreatment HDL3 was 28%, and post-treatment this increased to 50% (P < 0.01). Multivariate analyses indicated that the increased capacity of HDL3 to promote free cholesterol efflux was, in part, due to increased HDL3 phospholipid content and a more adequate fluidity of the molecule. These findings suggest that bezafibrate induces a lowering of plasma triglycerides and that the resultant physico-chemical alterations of the HDL3 molecule make it more efficient as an acceptor of intracellular free cholesterol.

Retardation of coronary atherosclerosis: the Bezafibrate Coronary Atherosclerosis Intervention Trial (BECAIT) and other angiographic trials.

A large number of both primary and secondary preventive trials suggest that treatment of elevated plasma lipids may reduce the frequency of coronary heart disease (CHD) events. Meta-analyses indicate that for every 10% reduction of cholesterol, CHD mortality is lowered by 13% and all-cause mortality by 10%. Experience from several angiographic trials also suggests that coronary atherosclerosis can be retarded, and in some instances limited regression induced, by low-density lipoprotein (LDL)-cholesterol reduction and/or high-density lipoprotein (HDL)-cholesterol elevation. Coronary angiographic studies have shown that although the effects on retardation/regression of altherogenic lesions have been small, with luminal diameter changes of around 0.10 mm, the effects on clinical events were more substantial, with reductions of the order of 50%. There is also evidence that it is the mild and moderate lesions that are of particular concern with respect to the occurrence of clinical coronary events. The progression of atherosclerosis and the occurrence of coronary events are probably not exclusively dependent on a lowering of LDL-cholesterol concentrations. Analyses from the Monitored Atherosclerosis Regression Study (MARS), the Cholesterol Lowering Atherosclerotic Study (CLAS), and the Programs on the Surgical Control of the Hyperlipidaemias (POSCH) indicate that triglyceride-rich lipoproteins may also be of importance for the progression of mild/moderate lesions in subjects treated with cholesterol-lowering regimens. Recently, the results of the 5-year Bezafibrate Coronary Atherosclerosis Intervention Trial (BECAIT) demonstrated that bezafibrate significantly retarded the progression of coronary atheroma and coronary events in young male survivors of myocardial infarction, as assessed by changes in minimum lumen diameter. This positive outcome is most likely due to the beneficial treatment effects on the levels of serum triglycerides (-31%), plasma fibrinogen (-12%), and HDL cholesterol (+9%). The results of the BECAIT on progression of coronary atherosclerosis are comparable with those of two recent angiographic trials with HMG-CoA reductase inhibitors, the Multicenter Anti-Atheroma Study (MAAS), and the Regression Growth Evaluation Statin Study (REGRESS), despite different lipid and metabolic effects. BECAIT is the first controlled angiographic study to show that a fibrate can significantly retard the progression of coronary atherosclerosis. The exact mechanisms by which this occurs remain to be elucidated. However, the results of BECAIT illustrate the importance of factors other than LDL cholesterol in the progression of coronary atherosclerosis.

Bezafibrate and simvastatin combination therapy for diabetic dyslipidaemia: efficacy and safety.

OBJECTIVE: To determine the efficacy and safety of a statin-fibrate combination in diabetes patients. DESIGN.: An open 21-month trial in which each patient first received the single drug for 6 months and then a combination of the two for 1 year. SETTING: Three lipid clinics in university-based tertiary care hospitals. PATIENTS: One hundred and forty-eight patients with type 2 (non-insulin-dependent, NIDDM) diabetes mellitus under stable control for 3 months by means of diet and oral hypoglycaemic medication. INTERVENTION: Patients from one clinic (n = 48) received bezafibrate slow release (400 mg day-1), and patients from the other two clinics (n = 100) received simvastatin 20 mg day-1. Six months later, all patients were switched to a daily combination of 400 mg bezafibrate slow release and 20 mg simvastatin for 1 year. RESULTS: The combination of statin and fibrate led to a 23% reduction in total cholesterol, 42% reduction in triglycerides, 29% reduction in LDL-c, 25% increase in HDL-c, 10% decrease in fibrinogen and 19% reduction of Lp(a) levels, and a decrease in the cholesterol/HDL-c ratio (from 8.9 to 5.4) in all 148 patients. Cardiovascular (CV) event rate was significantly reduced from 9.5% during the first 6 months of the study to less than 2% during the last year of the study (whilst on combination Rx). Side-effects with all treatments included only two patients who developed myopathy when on the combined regimen and one on the single statin regimen. However, plasma creatinine phosphokinase (CPK) levels doubled (but remained within the normal range) in most of the patients on combination therapy, compared with only a mild increase in patients receiving a single medication. CONCLUSIONS: The statin and fibrate combination was found to be more efficacious than a single medication for treatment of diabetic dyslipidaemia, as evidenced by improvement in the lipoprotein profile, reductions in Lp(a), fibrinogen and CV event rate, and almost no clinically significant side-effects.

The short term effects of bezafibrate on the hypertriglyceridaemia of moderate to severe uraemia.

Hypertriglyceridaemia, an atherogenic risk factor, is a well recognised complication of uraemia, and is present in the earliest stages of the disease. Bezafibrate is an effective hypolipidaemic agent, and its effect in moderate to severe uraemia is documented in this study. Significant reductions in serum triglyceride and cholesterol have been achieved after 1 month's therapy with a reduced dosage of bezafibrate. A reduction in the hyperinsulinaemia was also seen, but no change in the fractional removal rate of injected lipid emulsion (K2) was observed. An accelerated decline in some patients' renal function was observed, which was partially reversed on cessation of treatment. Reversible elevations in the serum creatinine phosphokinase were also seen, but no patient exhibited the myositis-like syndrome associated with clofibrate.

Bezafibrate therapy and biliary lipids: effects of short-term and long-term treatment in patients with various forms of hyperlipoproteinaemia.

Several hypolipidaemic drugs increase biliary cholesterol saturation and induce the formation of cholesterol gallstones. In order to determine the influence of bezafibrate, a clofibrate analogue with hypolipidaemic properties, on bile lipid composition, we studied twelve patients with various forms of hyperlipoproteinaemia (six type IIA, three type IIB and three type IV hyperlipoproteinaemia; six had a genetic diagnosis of familial hypercholesterolaemia and five familial combined hyperlipidaemia). After 4 weeks of therapy, when serum lipids were significantly reduced, the relative proportion of cholesterol in stimulated fasting duodenal bile was increased by 28% (P less than 0.001). Phospholipids were concomitantly increased and bile acids decreased, resulting in an increase in biliary cholesterol saturation from 89 +/- 4% to 105 +/- 8% (SEM, P less than 0.02). The changes induced were similar in patients with familial hypercholesterolaemia and familial combined hyperlipidaemia. After 1 year of continued treatment, serum lipid responses were unaltered. The changes in biliary lipids were also persistent as the relative cholesterol concentration remained increased by 33% (P less than 0.01) and cholesterol saturation averaged 106 +/- 8% (P less than 0.02). Although the effect on bile cholesterol appeared to be transient in some patients, the results of the present study suggest that the risk of cholesterol gallstone formation may be increased during bezafibrate therapy.

The effect of bezafibrate on hyperlipidaemia in experimental nephrotic syndrome in rats.

The effects of bezafibrate on hyperlipidaemia in experimental nephrotic syndrome in rats has been investigated. The treated group received bezafibrate 10 mg kg-1 p.o. daily. No significant differences in total serum cholesterol occurred, but a significant reduction in serum triglyceride (P less than 0.005) and elevation in HDL cholesterol (P less than 0.005) occurred. These findings may have implications for therapeutic intervention in severe hyperlipidaemia of the nephrotic syndrome in man.

Bezafibrate-induced myopathy: no evidence for defects in muscle metabolism.

A 58-year-old man with chronic renal failure developed severe muscle pain and tenderness 1 week after starting bezafibrate 400 mg daily. Serum creatine kinase was 32,280 U/l. Muscle biopsy revealed scattered necrotic fibers and mild type 2b atrophy. Muscle total and free carnitine were at the upper limits of the normal range. Biochemical investigations of muscle homogenate showed normal carnitine pelmityl transferase (CPT) as well as normal individual glycolytic and mitochondrial enzyme activities. Withdrawal of the drug was followed by rapid clinical improvement. Our study casts doubt on the hypothesis that bezafibrate is able to affect muscle metabolic pathways. It is likely that the drug acts on cholesterol constituents of the muscle membrane, producing discontinuities of the sarcolemma and initiating cell necrosis.

Sustained-release bezafibrate corrects lipid abnormalities in patients on continuous ambulatory peritoneal dialysis.

A study was undertaken in 24 Chinese patients on maintenance continuous ambulatory peritoneal dialysis, using bezafibrate in its sustained-release form to correct lipid abnormalities. Six patients who received 400 mg/day developed severe muscle weakness with grossly elevated creatine phosphokinase activities within 3 weeks. The drug was discontinued and the symptoms disappeared. The remaining 18 patients received 400 mg/week for 8 weeks. There was a significant decrease in serum triglyceride (2.74 +/- 0.33 to 1.86 +/- 0.17 mmol/l at the 4th week and 1.65 +/- 0.4 mmol/l at the 8th week). Concomitantly, serum total cholesterol decreased. Serum high-density lipoprotein cholesterol increased significantly (from 1.18 +/- 0.082 to 1.36 +/- 0.060 mmol/l at the 4th week and 1.40 +/- 0.103 mmol/l at the 8th week). Post-heparin lipoprotein and hepatic lipases were measured by a substrate-specific method. The former increased significantly (p = 0.000) after bezafibrate treatment while the latter did not change. All parameters of lipid metabolism returned towards baseline 4 weeks after discontinuation of therapy. The drug was well tolerated at 400 mg/week and there was no significant rise in serum creatine phosphokinase.

Soluble intercellular adhesion molecule-1 and risk of future ischemic stroke: a nested case-control study from the Bezafibrate Infarction Prevention (BIP) study cohort.

BACKGROUND AND PURPOSE: Inflammation is considered to be involved in the pathogenesis of ischemic stroke. Our purpose was to assess the role of soluble intercellular adhesion molecule-1 (sICAM-1) concentration, a marker of inflammation, in predicting future ischemic stroke among patients at risk because of chronic coronary heart disease. METHODS: We obtained baseline serum samples from patients with chronic coronary heart disease enrolled in the Bezafibrate Infarction Prevention trial (n=3090), which assessed the efficacy of bezafibrate in secondary prevention. Using a prospective nested case-control design, we measured baseline sICAM-1 concentration in sera of patients who developed ischemic stroke during a mean follow-up of 8.2 years (cases, n=134) and in age- and sex-matched controls without any subsequent cardiovascular events (n=134). RESULTS: Baseline serum concentrations of sICAM-1 were significantly higher in cases compared with controls (379 versus 350 ng/mL, P<0.05). sICAM-1 concentration at the highest quartile (>394 ng/mL) was associated with significantly higher relative odds of ischemic stroke compared with the lower concentrations after adjustment for potential confounding variables (relative odds, 2.1; 95% CI, 1.1 to 4.3). After fibrinogen and total white blood cell count were added to the multivariable model, the relative odds were 2.1 (95% CI, 1.1 to 4.2) and 2.2 (95% CI, 1.1 to 4.8), respectively. The risk associated with raised concentrations of sICAM-1 seemed to be highest for large disabling strokes of cardioembolic origin. CONCLUSIONS: Elevated concentrations of sICAM-1, a marker of inflammation, are associated with increased risk of ischemic stroke, independent of other traditional cerebrovascular risk factors and of plasma fibrinogen, among patients at increased risk because of manifest coronary heart disease.

Abnormalities in very low, low and high density lipoproteins in hypertriglyceridemia. Reversal toward normal with bezafibrate treatment.

The effects of triglyceridemia on plasma lipoproteins were investigated in 16 hypertriglyceridemic (HTG) subjects (222-2,500 mg/dl) before and after the initiation of bezafibrate therapy. Bezafibrate caused a mean reduction of 56% in plasma triglyceride and increased the levels of lipoprotein and hepatic triglyceride lipases by 260 and 213%, respectively. The natures of very low density lipoprotein (VLDL), isolated at plasma density and of low and high density lipoprotein (LDL and HDL), separated by zonal ultracentrifugation, were determined. HTG-LDL appears as multiple fractions whereas HTG-HDL is seen predominantly as HDL3. HTG-VLDL is relatively poor in apoproteins and triglycerides but enriched in free and esterified cholesterol. HTG-LDL (main fraction) is depleted of free and esterified cholesterol but enriched in apoprotein and triglyceride. It is also denser and smaller than normal. HTG-HDL3 is denser than N-HDL3 and demonstrates compositional abnormalities similar to those of HTG-LDL. With the reduction of the VLDL mass, all abnormalities revert towards normal. This is accompanied by an increase in LDL-apoprotein B and cholesterol levels, which indicates an increased conversion of VLDL to LDL. Significant correlations between plasma triglyceride and the degree of all abnormalities are shown. The data obtained during treatment corroborate these relationships. The observations support the concept that most abnormalities reflect the degree of triglyceridemia. We suggest that plasma core-lipid transfer protein(s) is an effector of the abnormal cholesteryl ester distribution. Its prolonged action on increasingly large and slowly metabolized VLDL populations would entail a correspondingly excessive transfer of cholesteryl ester to VLDL and of triglyceride to LDL and HDL. It is calculated that, in moderate HTG, LDL and HDL contain only 50% of the normal cholesterol load. It is suggested that cholesteryl ester redistribution in HTG might be important in regulating metabolic events.

Apolipoprotein A and B (Sf 100-400) metabolism during bezafibrate therapy in hypertriglyceridemic subjects.

This study describes the effects of bezafibrate, an analogue of clofibrate, on the plasma lipid and lipoprotein profiles of 11 hypertriglyceridemic subjects and on their metabolism of apolipoproteins A-I, A-II, and B. The major action of the drug was to lower plasma triglyceride (by 58%; P less than 0.01). This was accompanied by a reduction in the level of very low density lipoprotein apoprotein B (Svedberg units of flotation [Sf] 60-400), whose mean residence time in the plasma fell threefold (from 3.4 to 1.0 h). Synthesis of the B protein in this fraction was not significantly altered, so the drug acts to accelerate the transit of very low density lipoprotein particles down the delipidation cascade. The metabolism of very low density lipoprotein remnant apoprotein B (Sf 12-100) changed little in response to treatment, although we detected a 30% increment (P less than 0.05) in the plasma concentration of this fraction. The mean residence time of these remnant particles in the plasma did not correlate with that of Sf 100-400 very low density lipoprotein apoprotein B, nor was this parameter altered by the drug. The most consistent and significant perturbation seen in the Sf 0-12 fraction (low density lipoprotein) was a reduction in the fractional catabolism of its apoprotein B moiety (26%; P less than 0.05). In those subjects who were grossly hypertriglyceridemic and who responded well to treatment, the level of this protein rose substantially owing to a combined increase in its synthesis and a reduction in its catabolism. In the group as a whole, high density lipoprotein cholesterol rose 13% (P less than 0.02), and detailed examination showed that this was associated with a small but significant increment in the plasma concentration of the high density lipoprotein subfraction 2. High density lipoprotein subfraction 3 also rose on the average, but this was not a consistent feature in all patients. The plasma concentrations and turnovers of the A proteins (A-I and A-II) were not significantly altered by bezafibrate therapy.

Comparative pharmacokinetics of 400 mg bezafibrate after a single oral administration of a new slow-release preparation and the currently available commercial form.

Bezafibrate is a new lipid-lowering agent with a more pronounced pharmacological effect, a different metabolism and a much shorter apparent half-life than clofibrate. The serum concentration curves and the urinary excretion were determined in seventeen healthy volunteers after administration of 400 mg of a new slow-release preparation. The results were compared with those of a similar experiment in twenty healthy volunteers who received 400 mg as a single dose in the form of 2 tablets of Cedur, which is the currently marketed form in Germany (each tablet contains 200 mg bezafibrate). The areas under the serum concentration curves were not statistically significantly different (median of 31.3 mg . h/l for the slow-release and of 39.4 mg . h/l for the marketed preparation). Renal clearance differed only within the margin of biological variation. It can be assumed that the relative biological availability of both preparations is similar. In none of the volunteers were subjective or objective side-effects observed.
