Abstract
BACKGROUND A detailed summary and meta-analysis of the dose-related effect of pravastatin on lipids is not available. OBJECTIVES Primary objective To assess the pharmacology of pravastatin by characterizing the dose-related effect and variability of the effect of pravastatin on the surrogate marker: low-density lipoprotein (LDL cholesterol). The effect of pravastatin on morbidity and mortality is not the objective of this systematic review. Secondary objectives • To assess the dose-related effect and variability of effect of pravastatin on the following surrogate markers: total cholesterol; high-density lipoprotein (HDL cholesterol); and triglycerides. • To assess the effect of pravastatin on withdrawals due to adverse effects. SEARCH METHODS The Cochrane Hypertension Information Specialist searched the following databases for randomized controlled trials (RCTs) up to September 2021: CENTRAL (2021, Issue 8), Ovid MEDLINE, Ovid Embase, Bireme LILACS, the WHO International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also contacted authors of relevant papers regarding further published and unpublished work. The searches had no language restrictions. SELECTION CRITERIA Randomized placebo-controlled trials evaluating the dose response of different fixed doses of pravastatin on blood lipids over a duration of three to 12 weeks in participants of any age with and without evidence of cardiovascular disease. DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility criteria for studies to be included, and extracted data. We entered lipid data from placebo-controlled trials into Review Manager 5 as continuous data and withdrawal due to adverse effects (WDAEs) data as dichotomous data. We searched for WDAEs information from all trials. We assessed all trials using Cochrane's risk of bias tool under the categories of sequence generation, allocation concealment, blinding, incomplete outcome data, selective reporting, and other potential biases. MAIN RESULTS Sixty-four RCTs evaluated the dose-related efficacy of pravastatin in 9771 participants. The participants were of any age, with and without evidence of cardiovascular disease, and pravastatin effects were studied within a treatment period of three to 12 weeks. Log dose-response data over the doses of 5 mg to 160 mg revealed strong linear dose-related effects on blood total cholesterol and LDL cholesterol, and a weak linear dose-related effect on blood triglycerides. There was no dose-related effect of pravastatin on blood HDL cholesterol. Pravastatin 10 mg/day to 80 mg/day reduced LDL cholesterol by 21.7% to 31.9%, total cholesterol by 16.1% to 23.3%,and triglycerides by 5.8% to 20.0%. The certainty of evidence for these effects was judged to be moderate to high. For every two-fold dose increase there was a 3.4% (95% confidence interval (CI) 2.2 to 4.6) decrease in blood LDL cholesterol. This represented a dose-response slope that was less than the other studied statins: atorvastatin, rosuvastatin, fluvastatin, pitavastatin and cerivastatin. From other systematic reviews we conducted on statins for its effect to reduce LDL cholesterol, pravastatin is similar to fluvastatin, but has a decreased effect compared to atorvastatin, rosuvastatin, pitavastatin and cerivastatin. The effect of pravastatin compared to placebo on WADES has a risk ratio (RR) of 0.81 (95% CI 0.63 to 1.03). The certainty of evidence was judged to be very low. AUTHORS' CONCLUSIONS Pravastatin lowers blood total cholesterol, LDL cholesterol and triglyceride in a dose-dependent linear fashion. This review did not provide a good estimate of the incidence of harms associated with pravastatin because of the lack of reporting of adverse effects in 48.4% of the randomized placebo-controlled trials.

Abstract
As atherosclerosis begins in childhood, early diagnosis and treatment of familial hypercholesterolemia (FH) is considered necessary. The basic diagnosis of pediatric FH (under 15 years of age) is based on hyper-low-density lipoprotein (LDL) cholesterolemia and a family history of FH; however, in this guideline, to reduce overlooked cases, "probable FH" was established. Once diagnosed with FH or probable FH, efforts should be made to promptly provide lifestyle guidance, including diet. It is also important to conduct an intrafamilial survey, to identify family members with the same condition. If the level of LDL-C remains above 180 mg/dL, drug therapy should be considered at the age of 10. The first-line drug should be statin. Evaluation of atherosclerosis should be started using non-invasive techniques, such as ultrasound. The management target level is an LDL-C level of less than 140 mg/dL. If a homozygous FH is suspected, consult a specialist and determine the response to pharmacotherapy with evaluating atherosclerosis. If the response is inadequate, initiate lipoprotein apheresis as soon as possible.

Abstract
BACKGROUND Lipid abnormalities in people with diabetes are likely to play an important role in the development of atherogenesis. These lipid disorders include potentially atherogenic quantitative (increased triglyceride levels and decreased high-density lipoprotein-cholesterol [HDL-C] levels) and qualitative abnormalities of lipoproteins (changes in lipoprotein size, increase in triglyceride content of low-density lipoprotein (LDL) and HDL, glycation of apoproteins and increased susceptibility of LDL to oxidation). Guidelines from the two main diabetes organizations, the International Diabetes Federation and the American Diabetes Association, recommend the aggressive management of diabetic dyslipidaemia to reduce the risk of cardiovascular disease (CVD). Statins are the first choice pharmacological therapy to address diabetic dyslipidaemia due to their effectiveness at lowering LDL-C levels in patients with diabetes. Fibrates (peroxisome proliferator-activated receptor [PPAR]alpha ligands) target another aspect of dyslipidaemia by lower ing triglycerides (to a greater extent than statins) and raising HDL-C levels, especially when baseline levels are low. The PPARgamma agonist, pioglitazone appears to affect lipid metabolism by decreasing plasma triglycerides, increasing HDL-C and decreasing the number of small, dense atherogenic LDL particles. SCOPE This paper provides a review of the current literature (based on searches of MEDLINE and EMBASE from 1985 to 2005, inclusive) supporting the recommendations for the management of dyslipidaemia among patients with type 2 diabetes, including new strategies involving drug combinations that achieve good glycaemic and lipidaemic control that could potentially reduce the morbidity and mortality associated with type 2 diabetes.

Abstract
The HMG-CoA reductase inhibitors (statins) are effective in both the primary and secondary prevention of ischaemic heart disease. As a group, these drugs are well tolerated apart from two uncommon but potentially serious adverse effects: elevation of liver enzymes and skeletal muscle abnormalities, which range from benign myalgias to life-threatening rhabdomyolysis. Adverse effects with statins are frequently associated with drug interactions because of their long-term use in older patients who are likely to be exposed to polypharmacy. The recent withdrawal of cerivastatin as a result of deaths from rhabdomyolysis illustrates the clinical importance of such interactions. Drug interactions involving the statins may have either a pharmacodynamic or pharmacokinetic basis, or both. As these drugs are highly extracted by the liver, displacement interactions are of limited importance. The cytochrome P450 (CYP) enzyme system plays an important part in the metabolism of the statins, leading to clinically relevant interactions with other agents, particularly cyclosporin, erythromycin, itraconazole, ketoconazole and HIV protease inhibitors, that are also metabolised by this enzyme system. An additional complicating feature is that individual statins are metabolised to differing degrees, in some cases producing active metabolites. The CYP3A family metabolises lovastatin, simvastatin, atorvastatin and cerivastatin, whereas CYP2C9 metabolises fluvastatin. Cerivastatin is also metabolised by CYP2C8. Pravastatin is not significantly metabolised by the CYP system. In addition, the statins are substrates for P-glycoprotein, a drug transporter present in the small intestine that may influence their oral bioavailability. In clinical practice, the risk of a serious interaction causing myopathy is enhanced when statin metabolism is markedly inhibited. Thus, rhabdomyolysis has occurred following the coadministration of cyclosporin, a potent CYP3A4 and P-glycoprotein inhibitor, and lovastatin. Itraconazole has been shown to increase exposure to simvastatin and its active metabolite by at least 10-fold. Pharmacodynamically, there is an increased risk of myopathy when statins are coprescribed with fibrates or nicotinic acid. This occurs relatively infrequently, but is particularly associated with the combination of cerivastatin and gemfibrozil. Statins may also alter the concentrations of other drugs, such as warfarin or digoxin, leading to alterations in effect or a requirement for clinical monitoring. Knowledge of the pharmacokinetic properties of the statins should allow the avoidance of the majority of drug interactions. If concurrent therapy with known inhibitors of statin metabolism is necessary, the patient should be monitored for signs and symptoms of myopathy or rhabdomyolysis and the statin should be discontinued if necessary.

Abstract
OBJECTIVE To assess whether colesevelam hydrochloride is absorbed in healthy volunteers. METHODS A single-center, open-label, radiolabeled study was performed with 16 healthy volunteers. Subjects were administered non-radiolabeled colesevelam hydrochloride 1.9 g twice daily for 4 weeks, followed by a single dose of [14C]-colesevelam 2.4 g (480 pCi). These subjects continued to receive non-radioactive colesevelam 1.9 g twice daily for 4 days after administration of the radiolabeled dose. Blood, urine, and feces were collected immediately prior to administration of [14C]-colesevelam and at specified intervals after administration. The whole-blood equivalent concentration of colesevelam was calculated using data collected throughout the 96 hours following radiolabeled drug administration. The proportion of [14C]-colesevelam excreted through urine or feces was calculated based on the amount of radioactivity recovered up to 216 hours after the radiolabeled dose. RESULTS The mean cumulative total recovery of [14C]-colesevelam in urine and feces was 0.05% and 74%, respectively. Excluding 2 subjects for whom cumulative recovery was <25%, the mean cumulative fecal recovery was 82%. The mean maximum whole-blood equivalent concentration of colesevelam was 0.165+/-0.10 microg equiv/g 72 hours after administration of [14C]-colesevelam, which was estimated to be 0.04% of the administered dose. All blood samples contained <4 times the number of background counts (dpm). CONCLUSIONS The cumulative recovery data in urine and feces are consistent with the conclusion that colesevelam is not absorbed and is excreted entirely through the gastrointestinal system.

Abstract
Coronary heart disease is the most prevalent form of cardiovascular disease in the United States. Hyperlipidemia--specifically, increased total and low-density lipoprotein cholesterol levels--positively correlates with the development of coronary heart disease. Colesevelam, a nonabsorbed, water-insoluble polymer, is a new bile acid sequestrant that is effective in lowering total and low-density lipoprotein cholesterol levels. In several short-term, placebo-controlled studies, colesevelam has decreased total cholesterol levels by approximately 6 to 10% and low-density lipoprotein cholesterol levels by approximately 9 to 20%. When given in combination with atorvastatin, lovastatin, or simvastatin, low-density lipoprotein cholesterol levels were decreased more than with colesevelam alone. Its unique hydrogel formulation may also minimize the potential for gastrointestinal adverse effects, which are common with other bile acid sequestrants. There have been few published studies available concerning this drug; no long-term studies and few large-scale studies have been published.

Abstract
The 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors have become the drugs of choice for the treatment of patients with hypercholesterolemia. However, one of the major concerns with these drugs is cost. In an attempt to develop a cost-effective treatment strategy for patients referred to our lipid clinic, we conducted a meta-analysis to estimate the lipid-lowering efficacy of the various HMG-CoA reductase inhibitors alone or in combination with niacin or cholestyramine. Based on cholesterol-lowering efficacy estimates derived from a literature-based meta-analysis, we performed a population-based treat-to-target analysis. Fifty-six trials with 101 monotherapy cohorts and 20 trials with 31 combination-therapy cohorts (573 patients) were included in the meta-analysis. Based on reduction in low-density lipoprotein cholesterol (LDL-C), the most effective monotherapy was atorvastatin and the least effective monotherapy was fluvastatin. Combination therapy was more effective in reducing LDL-C than monotherapy with the respective HMG-CoA reductase inhibitor. However, on the basis of dollars spent per percentage of LDL-C reduction, combination therapy was frequently less cost-effective than monotherapy. In addition, combination therapy was associated with a higher rate of noncompliance and a greater risk of drug-drug interactions. As a result, we based our treat-to-target analysis on the use of monotherapy as first-line treatment, with combination therapy reserved for patients failing to achieve the target LDL-C levels of the US National Cholesterol Education Program Adult Treatment Panel II (NCEP ATP-II) with monotherapy. In the population-based treat-to-target analysis, atorvastatin was the most cost-effective drug for high-risk patients (those with coronary heart disease [CHD]), whereas fluvastatin was the most cost-effective agent for low-risk patients (<2 risk factors for CHD) and moderate-risk patients (> or =2 risk factors for CHD). If 1 drug is chosen to treat all patients (i.e., in cases of formulary restriction), atorvastatin would be the most cost-effective agent. In adapting the findings on cholesterol-lowering efficacy from this analysis to our lipid clinic, we concluded that the most cost-effective treatment approach is to individualize the selection of an HMG-CoA reductase inhibitor based on both coronary risk and the LDL-C reduction required to achieve NCEP ATP-II goals. Based on our results, 2 agents--atorvastatin and fluvastatin--should be available on the formulary.

Abstract
Recent studies have documented the long-term impact of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors on mortality and morbidity related to coronary heart disease, establishing the link between lowering cholesterol levels and reducing cardiac events. Our study was a comparative literature review and meta-analysis of the efficacy of four HMG-CoA reductase inhibitors-fluvastatin, lovastatin, pravastatin, and simvastatin-used in the treatment of patients with hypercholesterolemia. The data sources for our meta-analysis of the efficacy of these cholesterol-lowering agents were 52 randomized, double-masked clinical trials with at least 25 patients per treatment arm. The results showed all four agents to be effective in reducing blood cholesterol levels. We computed summary efficacy estimates for all published dose strengths for the four agents. Fluvastatin 20 mg/d reduced low-density lipoprotein cholesterol (LDL-C) levels by 21.0% and total cholesterol (total-C) levels by 16.4%; fluvastatin 40 mg/d reduced these levels by 23.1% and 17.7%, respectively. Lovastatin 20 mg/d reduced LDL-C levels by 24.9% and total-C levels by 17.7%; lovastatin 80 mg/d reduced these levels by 39.8% and 29.2%, respectively. Pravastatin 10 mg/d reduced LDL-C levels by 19.3% and total-C levels by 14.0%; pravastatin 80 mg/d reduced these levels by 37.7% and 28.7%, respectively. Simvastatin 2.5 mg/d reduced LDL-C levels by 22.9% and total-C levels by 15.7%; simvastatin 40 mg/d reduced these levels by 40.7% and 29.7%, respectively. The results of our meta-analysis can be used in conjunction with treatment objectives and comparative cost-effectiveness data for these agents to decide appropriate therapeutic alternatives for individual patients.

Abstract
A total of 96 patients with moderate elevations of low-density lipoprotein (LDL) cholesterol were randomly assigned to 4 different double-blind treatment regimens: placebo; colestipol 5 g and lovastatin 20 mg/day (C5 + L20); colestipol 10 g and lovastatin 20 mg/day (C10 + L20); and lovastatin 40 mg/day (L40). During 12 weeks of therapy, C10 + L20 achieved the greatest reduction in total cholesterol (-32%) and LDL cholesterol (-48%) levels from baseline. This combination also exhibited significantly greater reductions in LDL cholesterol levels than the C5 + L20 and L40 groups (p < 0.01). The differences in total and LDL cholesterol reduction between the C5 + L20 and L40 groups were not significant. Similar changes and differences between treatments were seen in apolipoprotein B levels. Whereas mean total apolipoprotein A-I levels increased with all treatments (p < 0.05), lipoprotein particles A-I were significantly increased in the C10 + L20 group (p < 0.01) only. Results demonstrate that the combination of low-dose lovastatin (20 mg/day) with low-dose colestipol (5 or 10 g/day) produces LDL cholesterol reductions equal to or greater than higher doses of lovastatin (40 mg/day). In addition, low-dose combinations are > 25% more cost-effective than high-dose monotherapy.

Abstract
In a comparative study, 158 patients with type IIa or IIb primary hypercholesterolemia received either placebo, nicotinic acid extended-release capsules (0.5 to 1.0 g twice daily), pravastatin (40 mg at bedtime), or the combination for a short-term, 8-week period. A long-term, 88-week phase followed in which the addition of other lipid-lowering agents was permitted. During the short-term phase, low-density lipoprotein cholesterol levels were lower, in relation to baseline, with nicotinic acid treatment (-21%) than with placebo (P < or = 0.05), with pravastatin (-33%) than with either placebo (p < or = 0.001) or nicotinic acid (p < or = 0.05) and with combination therapy (-49%) than with the other 3 treatments (p < or = 0.05) at all weeks measured. At week 8, high-density lipoprotein cholesterol levels were increased, in relation to placebo, by nicotinic acid treatment (12%; p < or = 0.05), pravastatin therapy (13%; p < or = 0.01) and combination therapy (16%; p < or = 0.01). Adverse events were less frequent in the pravastatin and placebo groups (p < or = 0.05). In comparison with placebo, treatment with nicotinic acid resulted in significant increases in aspartate and alanine aminotransferase. The placebo and pravastatin groups did not differ significantly regarding adverse events or laboratory parameters. Similar results were observed in the long-term phase. Therefore, pravastatin is very effective and well tolerated in the treatment of type IIa or IIb primary hypercholesterolemia, and is superior to nicotinic acid in both efficacy and adverse event profile.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This article has focused on the appropriate indications for lipid-lowering drugs in adult patients with different lipoprotein disorders, which we have divided into primary hypercholesterolemia, combined hyperlipidemia,and hypertriglyceridemia. The mechanism of action, efficacy, and safety profile of the major drugs have been reviewed, and based on this information, we have presented our views on the appropriate drugs of first choice and appropriate second-choice agents for treatment of adult patients with different dyslipidemias. The rationale for the use of hypolipidemic drugs is strongest in patients with hyperlipidemia who concurrently have evidence for coronary or peripheral vascular disease, in whom the goal of secondary prevention is to retard further progression of atherosclerosis and potentially induce some regression, whereas in selected high-risk patients without evidence of atherosclerosis, the goals of therapy are to prevent the premature development of CAD or, in patients with severe hypertriglyceridemia, prevent the adverse sequelae of hepatomegaly, splenomegaly, and potentially pancreatitis. We have focused on the use of hypolipidemic drugs in adult patients, and the guidelines discussed are not appropriate for use in children with hyperlipidemia, in whom drug therapy should be undertaken selectively and in consultation with a lipid specialist. Many areas of controversy in the use of lipid-lowering drugs remain to be addressed by future studies; these include the use of lipid-lowering drugs in patients with secondary causes of hyperlipidemia (e.g., the nephrotic syndrome), the use of lipid-lowering drugs in women, and recommendations for drug therapy in older patients.

Abstract
The goals of drug therapy in adult patients with heterozygous familial hypercholesterolemia (FH) are directed at reducing plasma concentrations of low density lipoproteins (LDL), with a secondary goal in selected patients to concurrently decrease elevated plasma concentrations of lipoprotein(a), triglycerides, and potentially exert favorable effects on the concentrations of high density lipoproteins (HDL). Desirable goals of therapy are to reduce concentrations of LDL cholesterol to < 130-160 mg/dL in patients without evidence of coronary artery disease, and, in my opinion, to < 100 mg/dL in patients with evidence of coronary artery disease. The bile acid sequestrants, cholestyramine and colestipol, reduce LDL concentrations by 23-36%, when given in doses of 4-6 scoops/day, but reduce LDL concentrations to desirable levels in only 10-15% of patients. Similarly, nicotinic acid, in doses of 3-6 g/day, is capable of reducing LDL concentrations by up to 30%, but the majority of patients still remain hypercholesterolemic. Inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, which include lovastatin, simvastatin, and pravastatin, are the most effective of the currently available drugs and show dose-dependent effects on the concentrations of LDL cholesterol, which decrease by 20-45% in response to these drugs when used over the full dosage range. However, even with these agents, concentrations of LDL cholesterol remain > 200 mg/dL in one-third of male and female patients with heterozygous FH and remain > 160 mg/dL in 75-80% of treated patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVES To compare the efficacy and safety of increasing doses (0, 10, 20 and 40 mg day-1, each dose for 6 weeks) of the inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase, simvastatin and pravastatin, in the treatment of primary hypercholesterolaemia. DESIGN Randomized, double-blind study with two parallel groups. SETTING Two specialist lipid clinics in the Netherlands. SUBJECTS Forty-eight patients aged 25-66 years with primary hypercholesterolaemia (mean serum cholesterol 10.2 mmol-1). MAIN OUTCOME MEASURES Total serum cholesterol, triglycerides, lipoproteins, apolipoproteins A-I and B, laboratory safety parameters and sleep questionnaires. RESULTS Both drugs induced a dose-dependent reduction in the mean total and low-density lipoprotein cholesterol concentration (P < 0.001); low-density lipoprotein cholesterol decreased from 32 to 43% by simvastatin and from 23 to 33% by pravastatin. There was an overall difference in the mean relative change from baseline in favour of simvastatin (total cholesterol, P < 0.01; LDL cholesterol P < 0.001). Both drugs reduced serum triglycerides by 10-15%. The changes in apolipoprotein B and the differences in efficacy between the two drugs paralleled those of total and low-density lipoprotein cholesterol. Adverse experiences were mild and did not differ between treatment groups; in each group, one subject discontinued medication because of complaints of dizziness. Sleep questionnaires revealed different degrees of sleep problems, unaffected by active treatment. CONCLUSIONS Simvastatin appeared to be more potent than pravastatin in lowering total cholesterol, low-density lipoprotein cholesterol and apolipoprotein B, whereas both drugs had the same short-term safety profile.

Abstract
We studied the effects of the 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase inhibitors simvastatin and pravastatin on the in vitro susceptibility of low-density lipoprotein (LDL) to oxidation. Twenty-three hypercholesterolaemic patients (mean serum cholesterol 9.7 mmol l-1) were treated with increasing doses of either simvastatin or pravastatin for 18 weeks. No significant differences in effect on lipid levels between the two drugs were found. Treatment resulted in lowering of total cholesterol and LDL-cholesterol by maximally 30% and 34%, respectively. Chemical composition analysis showed that LDL particles contained relatively more protein and less free cholesterol and cholesteryl-ester after treatment. The LDL cholesterol/protein ratio decreased from 1.24 +/- 0.21 to 0.97 +/- 0.23 (n = 20). By continuous monitoring of in vitro oxidation it appeared that LDL was less susceptible to oxidation after drug treatment. Maximal rate of diene production was significantly decreased from 19.7 +/- 3.1 to 18.5 +/- 3.3 nmol min-1 mg-1 LDL; total diene production decreased significantly from 420.3 +/- 67.6 to 380.5 +/- 49.1 nmol mg-1 LDL; the lag time was unchanged throughout the study. These studies show that HMG-CoA reductase inhibitors reduce the oxidizability of LDL by altering its composition.

Abstract
PURPOSE To compare the efficacy and safety of pravastatin, gemfibrozil, combined therapy, and placebo in the treatment of hypercholesterolemia. PATIENTS AND METHODS At 5 centers in Sweden and 2 in Finland, 290 ambulatory patients were randomized to active treatment or placebo for 12 weeks following a single-blind placebo lead-in period. The study was double-blind and placebo-controlled. Patients has plasma total cholesterol levels of at least 6.0 mmol/L or in the 90th percentile by age and sex and triglycerides less than 4.0 mmol/L. Concentrations of lipids, lipoproteins, and apolipoproteins were measured, and clinical laboratory tests included liver function and creatine kinase determinations. RESULTS Pravastatin reduced total cholesterol (26.3% versus 15.2%, p < or = 0.01), low-density lipoprotein cholesterol (LDL-C) (33.5% versus 16.8%, p < or = 0.01), and apolipoprotein B (28.8% versus 15.3%, p < or = 0.01) more than gemfibrozil. Gemfibrozil reduced very-low-density lipoprotein cholesterol (VLDL-C) (49.1% versus 21.9%, p < or = 0.01) and triglycerides (42.2% versus 14.2%, p < or = 0.01) and increased high-density lipoprotein cholesterol (HDL-C) (15.2% versus 5.9%, p < or = 0.01) more than pravastatin. Pravastatin and gemfibrozil increased apolipoprotein A-I comparably (3.3% versus 5.0%, p = NS). The combination significantly (p < or = 0.01) reduced total cholesterol (29.0%), LDL-C (37.1%), VLDL-C (49.4%), and apolipoprotein B (31.6%), and increased HDL-C (16.8%). The combination reduced the total cholesterol/HDL-C (39.3%) and LDL-C/HDL-C (45.8%) ratios significantly (p < 0.01). Adverse events and clinical laboratory abnormalities were generally mild and transient in all groups, although creatine kinase tended to be higher with combination therapy. Study drugs were withdrawn from two patients with asymptomatic creatine kinase elevations. Severe myopathy was not observed; however, the presence of subclinical musculoskeletal effects cannot be excluded. CONCLUSIONS Co-administration of pravastatin and gemfibrozil combined the specific effects of the two drugs on lipoprotein concentrations and ratios. The incidence of side effects was low; severe myopathy did not occur. The combination may be useful in selected cases of combined hyperlipidemia; however, since myopathy at a low incidence or after long-term therapy cannot be excluded, the routine use of combination therapy is not advisable.

Abstract
While the benefit of cholesterol-lowering in the elderly has yet to be proven in clinical trials, individuals at high risk of coronary events who otherwise enjoy a good quality of life, should not be denied cholesterol-lowering therapy on the basis of age alone. Moreover, hypolipidaemic drugs are already extensively used in the aged. The HMG-CoA reductase inhibitors lovastatin, simvastatin and pravastatin are potent well tolerated hypolipidaemic therapies in young subjects. Although there have been few studies on their use in elderly subjects, the available data suggest the efficacy and safety of HMG-CoA reductase inhibitors in similar to that established for younger age groups.

Abstract
The effects of the HMG CoA reductase inhibitors lovastatin and pravastatin on serum lipids, lipoproteins and apolipoproteins have been studied in 35 patients with primary hypercholesterolaemia. LDL cholesterol was lowered to the same extent by both agents compared on a mg basis of each drug per day. HDL cholesterol was increased by lovastatin but not by pravastatin. The reduction in serum triglycerides, VLDL triglycerides and VLDL cholesterol was more pronounced after lovastatin than pravastatin. After 1 year the effect of combined treatment with 40 mg pravastatin and 8 g cholestyramine on the reduction in LDL cholesterol (-39%) in 13 patients was comparable to that of 80 mg lovastatin plus 8 g cholestyramine (-40%) in 12 patients with identical baseline values. Differences were also found in the effects of the combination therapy with the two drugs on HDL cholesterol, serum triglycerides, VLDL triglycerides, VLDL cholesterol, and apolipoproteins.

Abstract
Hypercholesterolemia (HC) is one of the primary risk factors for atherosclerosis. Patients with familial hypercholesterolemia (FH) or combined hypercholesterolemia-hypertriglycerinemia (CHH) are at risk to develop premature atherosclerosis. Animal models have revealed that diet-induced HC in vivo leads to an increased adhesion of monocytes to the endothelium of the vessel wall. Changes in the monocytes, endothelial cells, or serum components may lead to the increased monocyte adhesion that results in atherosclerotic plaque formation. In the present study, we investigated the binding of the monocyte in an in vitro system. Incubation of freshly isolated monocytes from CHH patients with cultured human umbilical vein endothelial cells (HUVEC) gave a significant 60% increase in monocyte adhesion when compared with monocytes from healthy subjects. No such increase was observed using monocytes from nontreated FH patients. These data suggest that CHH results in in vivo alterations of the monocytes that lead to an increased in vitro adhesion to HUVEC, and that an increased level of plasma triglycerides is the major determinant, since HC alone does not induce this alteration.
