Status of lipid control in Bangladeshi subjects with type 2 diabetes mellitus on lipid-lowering drugs: a multicenter, facility-based, cross-sectional study.

BACKGROUND: Achievement of lipid targets is crucial in patients with type 2 diabetes mellitus (T2DM) to mitigate the risk of cardiovascular diseases (CVD). Data on lipid-control status among patients with T2DM in Bangladesh are scarce. This study was conducted to determine the lipid-control status among patients with T2DM who were on lipid-lowering drugs in the country. METHODS: This cross-sectional study was conducted in the diabetes outpatient departments of several tertiary hospitals in Bangladesh from January 2022 to December 2022. Adults of both sexes diagnosed with T2DM for at least one year and were on the lipid-lowering drug(s) for a minimum of 3 months were included in the study by consecutive sampling. Patients' data were collected by face-to-face interviews, and blood samples were collected for fasting lipid profile. The lipid target was set at < 200 mg/dL for total cholesterol (TC), < 150 mg/dL for triglyceride (TG), < 100 mg/dL for low-density lipoprotein cholesterol (LDL-C), > 40 mg/dL for high-density lipoprotein cholesterol (HDL-C), and < 160 mg/dL for non-HDL cholesterol (non-HDL-C). RESULT: Three thousand sixty patients (age 44.7 ± 13.3 years, female 57%) with T2DM were evaluated. Overall, almost 81% of the study subjects achieved the LDL-C target. Besides, TC, TG, HDL-C, and non-HDL-C targets were achieved by 40.8, 21.6, 66.3, and 44.1% of patients, respectively. However, all the lipid parameters were under control in only 8.8% of patients. Almost 77.6% of the patients with ischemic heart disease, 81.5% of patients with stroke, and 65% of patients with CKD had LDL levels < 70 mg/dL. Only 10.03% achieved the HbA1c target of < 7%. 7.4% of patients achieved both HbA1c < 7% and LDL < 100 mg/dL and 5% achieved both HbA1c < 7% and LDL < 70 mg/dL. Advanced age (aOR 0.97, 95% CI 0.96, 0.98, p < 0.001), longstanding T2DM (aOR 0.53, 95% CI 0.39, 0.72, p < 0.001), and non-statin therapy (aOR 0.25, 95% CI 0.16, 0.37, p < 0.001) were negatively associated with lipid control (LDL < 100 mg/dL) while using oral hypoglycemic drugs or insulin (aOR 2.01, 95% CI 1.45, 2.77, p < 0.001) and having cardiovascular comorbidity (aOR 3.92, 95% CI 3.00, 5.12, p < 0.001) were positively associated with lipid control. CONCLUSION: Though most patients with T2DM achieved their target LDL level, the prevalence of both glycemic and overall lipid control was low in our study despite lipid-lowering therapy.

Association between statin use & risk of diffuse large B-cell lymphoma: A systematic review & meta-analysis.

Background & objectives: Statin use has been shown to be associated with a decreased risk of several types of cancer, however, the data on diffuse large B-cell lymphoma (DLBCL) are still inconclusive. This study aimed to systematically summarize all available data on this association and conduct a meta-analysis on the same. Methods: A systematic review was performed using EMBASE and MEDLINE databases from inception upto October 2019 with a search strategy that included terms such as 'statin' and 'DLBCL'. Eligible studies included either case-control or cohort studies that reported the association between statin use and the risk of DLBCL. Relative risk, odds ratio (OR), hazard: risk ratio or standardized incidence ratio of this association and standard error were extracted and combined for calculating the pooled effect estimate using random-effects, generic inverse variance method. Results: A total of 1139 articles were screened. Of these six studies satisfied the inclusion criteria and were included for the meta-analysis. Statin use was associated with a significantly reduced risk of DLBCL with the pooled OR of 0.70 (95% confidence interval, 0.56-0.88; I[2]=70%). The funnel plot (fairly symmetric) was not suggestive of the presence of a publication bias. Interpretation & conclusions: The present systematic review and meta-analysis found that statin use is associated with a 30 per cent reduced odds of DLBCL. However, the pooled analysis utilized data from observational studies so causation cannot be concluded upon. Hence, it suggested that randomized-controlled studies are still needed to confirm this potential benefit.

Association of aspirin and statin use with the risk of liver cancer in chronic hepatitis B: A nationwide population-based study.

BACKGROUND & AIMS: Aspirin and statins have been suggested to prevent hepatocellular carcinoma (HCC). However, the combined effects of aspirin and statins on HCC risk in patients with chronic hepatitis B (CHB) are not clear. METHODS: A nationwide nested case-control study was performed with data from the National Health Insurance Service gathered between 2005 and 2015 in Korea. In a cohort of 538,135 treatment-naïve, non-cirrhotic patients with CHB, 6,539 HCC cases were matched to 26,156 controls and were analysed by conditional logistic regression. Separate historical cohort studies for each drug were analysed by time-dependent Cox regression as a sensitivity analysis. RESULTS: In the nested case-control study, statins (OR 0.34; 95% CI 0.32-0.37) and aspirin (OR 0.92; 95% CI 0.85-0.99) were significantly associated with a HCC risk reduction. However, dose-dependent risk reduction was observed only with statins. By sensitivity analysis in the historical cohorts, statin users (n = 244,455; HR 0.67; 95% CI 0.66-0.68) and aspirin users (n = 288,777; HR 0.81; 95% CI 0.80-0.82) had significantly lower HCC risk. In the drug-stratified analyses, statins were associated with significantly reduced risk of HCC regardless of aspirin, whereas aspirin did not show such associations. CONCLUSIONS: In this nationwide population-based study of patients with CHB, statin use was consistently associated with a significant and dose-dependent reduction in HCC risk. In contrast, the association between aspirin use and HCC risk reduction was not dose-dependent and was suggested to be confounded by statins.

Opposite effects of statins on the risk of tuberculosis and herpes zoster in patients with diabetes: A population-based cohort study.

It remains uncertain whether statin use is associated with the risks of tuberculosis (TB) and herpes zoster in patients with type 2 diabetes. This study aims to assess the effects of statins vs nonstatin lipid-lowering agents on the risk of these infectious diseases in patients with diabetes. METHODS: Participants in the Taiwan National Health Insurance Research Database diagnosed with type 2 diabetes in 2001-2013 were classified as statin users, nonstatin users and lipid-lowering drug-free groups. Participants were observed for incident TB and herpes zoster from diabetes diagnosis until treatment crossover or December 2013. Statin user and nonstatin user were the time-dependent variables in Cox regression analysis. RESULTS: Over 240 782 person-years of observation, statin users (n = 17 696) were associated with a lower TB risk than nonstatin users (n = 5327) and the drug-free group (n = 22 316) (adjusted hazard ratio [aHR]: 0.66; 95% confidence interval [CI]: 0.44-0.99 and aHR: 0.57; 95% CI: 0.44-0.73). Compared with nonstatin users, statin users showed a dose-dependent association with TB risk (low-potency statin users, aHR: 0.692; 95% CI: 0.455-1.053; high-potency users, aHR: 0.491; 95% CI: 0.241-0.999). Statin users presented with a higher risk of herpes zoster than nonstatin users and the drug-free group (aHR: 1.23; 95% CI: 1.01-1.50 and aHR: 1.20; 95% CI: 1.09-1.33). The risks of TB and herpes zoster were not statistically different between nonstatin users and the drug-free group. CONCLUSION: Compared with nonstatin drugs, statin use was specifically associated with a decreased risk of TB but a moderately increased risk of herpes zoster in this cohort study.

23,24-Dihydrocucurbitacin B promotes lipid clearance by dual transcriptional regulation of LDLR and PCSK9.

23,24-Dihydrocucurbitacin B (designated as C95 in this article) is a cucurbitane triterpenoid that has been shown to possess a variety of pharmacological activities, such as anti-inflammatory and anti-HIV-1 activities etc. In this study, we investigated the effects of 23,24-dihydrocucurbitacin B on lipid regulation. We showed that 23,24-dihydrocucurbitacin B (1-5 µM) dose-dependently promoted DiI-LDL uptake in HepG2 cells by upregulating low-density lipoprotein receptor (LDLR) protein. In HepG2 cells, 23,24-dihydrocucurbitacin B (1-10 µM) dose-dependently enhanced LDLR promoter activity by elevating the mature form of SREBP2 (sterol regulatory element binding protein 2) protein levels on one hand, and inhibited PCSK9 (proprotein convertase subtilisin/kexin type 9) promoter activity by attenuating HNF1α (hepatocyte nuclear factor-1α) protein levels in nuclei on the other hand. Consequently, the expression of LDLR protein markedly increased, whereas the PCSK9-mediated LDLR protein degradation decreased. In a high-cholesterol LVG golden Syrian Hamster model, administration of 23,24-dihydrocucurbitacin B (30 mg · kg-1⋅ d-1, intragastric, for 3 weeks) significantly decreased the serum LDL-cholesterol (LDL-C) levels. PCSK9 protein levels in the serum and liver tissues were significantly decreased, whereas LDLR protein levels in liver tissues were significantly increased in the treated animals as compared with the control animals. In conclusion, our study demonstrates for the first time that 23,24-dihydrocucurbitacin B exhibits dual transcriptional regulation of LDLR and PCSK9 in HepG2 cells by increasing SREBP2 protein levels and decreasing HNF1α protein levels in the nuclei. These results propose a new strategy to simultaneously manage LDLR and PCSK9 protein expression and provide a promising lead compound for drug development.

Statin use is associated with a reduced risk of fibrosis progression in chronic hepatitis C.

BACKGROUND & AIMS: Therapies that slow fibrosis progression in chronic liver disease are needed. Animal models have demonstrated that statins prevent the progression of hepatic fibrosis, but human data is lacking so far. We evaluated the association between statins and fibrosis progression in the HALT-C trial cohort. METHODS: Subjects with chronic hepatitis C (CHC) and advanced hepatic fibrosis underwent serial liver biopsies over 3.5 years. The primary outcome was a ⩾ 2-point increase in the Ishak fibrosis score on at least one of two serial biopsies. We used complementary log-log regression analysis to assess the association between statins and fibrosis progression among subjects without baseline cirrhosis. RESULTS: Fibrosis progression occurred in 3/29 (10%) statin users and 145/514 (29%) non-users. The unadjusted hazard ratio (HR) for fibrosis progression among statin users compared to non-users was 0.32 (95% CI 0.10-0.99). This association remained significant after adjusting for established predictors of histological outcome, including body mass index, platelets and hepatic steatosis (adjusted HR 0.31; 95% CI 0.10-0.97). The mean change in Ishak fibrosis score over the 3.5 year study period was -0.34 (SE 0.18) for statin users compared to +0.42 (SE 0.07) for non-users (p = 0.006, after adjustment for baseline fibrosis score). CONCLUSIONS: Statin use is associated with a reduced risk of fibrosis progression in advanced CHC. Our findings suggest a potential role for statins in preventing liver disease progression.

KDOQI US commentary on the 2013 KDIGO Clinical Practice Guideline for Lipid Management in CKD.

The National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI) guideline for management of dyslipidemia in chronic kidney disease (CKD) was published in 2003. Since then, considerable evidence, including randomized controlled trials of statin therapy in adults with CKD, has helped better define medical treatments for dyslipidemia. In light of the new evidence, KDIGO (Kidney Disease: Improving Global Outcomes) formed a work group for the management of dyslipidemia in patients with CKD. This work group developed a new guideline that contains substantial changes from the prior KDOQI guideline. KDIGO recommends treatment of dyslipidemia in patients with CKD primarily based on risk for coronary heart disease, which is driven in large part by age. The KDIGO guideline does not recommend using low-density lipoprotein cholesterol level as a guide for identifying individuals with CKD to be treated or as treatment targets. Initiation of statin treatment is no longer recommended in dialysis patients. To assist US practitioners in interpreting and applying the KDIGO guideline, NKF-KDOQI convened a work group to write a commentary on this guideline. For the most part, our work group agreed with the recommendations of the KDIGO guideline, although we describe several areas in which we believe the guideline statements are either too strong or need to be more nuanced, areas of uncertainty and inconsistency, as well as additional research recommendations. The target audience for the KDIGO guideline includes nephrologists, primary care practitioners, and non-nephrology specialists such as cardiologists and endocrinologists. As such, we also put the current recommendations into the context of other clinical practice recommendations for cholesterol treatment.

Are statins onco- suppressive agents for every type of tumor? A systematic review of literature.

INTRODUCTION: Statins, in the role of anti-cancer agents, have been used in many types of cancers with results in some cases promising while, in others, disappointing. AREAS COVERED: The purpose of this review is to identify and highlight data from literature on the successes or failure of using statins as anti-cancer agents. We asked ourselves the following two questions:1. Could statins, which are taken mostly to reduce cardiovascular risk, guarantee a lower incidence or a better cancer disease prognosis, concerning local recurrence, metastasis or mortality?2. Does statins intake (before and/or after cancer diagnosis) improve the prognosis or increase the chemotherapeutic action when combined with other anticancer therapies? For the first question twenty-seven manuscripts have been selected, for the second one, twenty-eight. EXPERT OPINION: There are data which correlate statins with a possible tumor suppressive action among the following cancers: breast, lung, prostate and head and neck. Lastly, for gastric cancer and colorectal there is no evidence of a correlation. The onco-suppressive efficacy of statins is mainly related to the histopathological and/or molecular characteristics of the tumor cells, which have different characteristics.

A study on cholesterol-cholesteryl ester metabolic homeostasis and drug intervention in hyperlipidemic hamsters using UHPLC-MS/MS.

Hyperlipidemia is a global metabolic disorder characterized by dysregulation of lipid metabolism. This dysregulation is closely associated with the altered homeostasis of cholesterol-cholesteryl ester (CE) metabolism in systemic circulation, and some organs. Additionally, the relationship between oxidized cholesteryl ester (oxCE) and the disease has also gained attention. Currently, there is a lack of comprehensive research on the alterations in cholesterol-CE metabolism in the context of hyperlipidemia, as well as the characteristics of lipid-lowering agents in regulating this metabolic state. Therefore, 40 oxCEs were identified in the hamster liver sample, and novel ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) methods were established for simultaneous analysis of cholesterol, 57 CEs, and 40 oxCEs in the serum, liver, adipose tissue, and intestine of hyperlipidemic hamsters. This study investigated the metabolic alterations between cholesterol-CE/oxCE in hyperlipidemic hamsters and those treated with lipid-lowering agents, including the Niemann-Pick-C1 like-1 protein (NPC1L1) inhibitor ezetimibe and the acyl coenzyme A: cholesterol acyltransferase (ACAT) inhibitor avasimibe. The study findings demonstrate metabolic disorders in cholesterol-CE/oxCE homeostasis in hyperlipidemic hamsters. Lipid-lowering agent therapy can improve the metabolic dysregulation caused by hyperlipidemia, with distinct characteristics: ezetimibe is more effective in reducing cholesterol, while avasimibe is more effective in reducing CEs/oxCEs. Eight potential biomarkers indicating the dysregulation of cholesterol-CE metabolism caused by hyperlipidemia and its improvement by lipid-lowering agents have been identified in the serum. This study offers new insights into the hyperlipidemia pathophysiology and the mechanisms of lipid-lowering agents from a novel perspective on cholesterol-CE/oxCE metabolic homeostasis.

Under-utilization of statins among people with HIV who were aged 40 years or older.

From June 2022 to April 2023, 1629 HIV-positive participants were assessed for the risk of atherosclerotic cardiovascular disease (ASCVD). The 10-year ASCVD risk of <5 %, 5 % to <7.5 %, ≥7.5 % to <20 % and ≥20 % were 59.9 %, 14.4 %, 20.7 % and 5.0 %, respectively; 440 (27.0 %) participants met the criteria for statin therapy, but only 171 (38.8 %) were prescribed statins.

The Association between Statin Use and Reduced Migraine Likelihood: A Comprehensive Analysis of Migraine Subtypes and Statin Types in a Nationwide Korean Cohort.

Despite growing interest in the preventive effects of statins, as lipid-lowering agents, on migraine attacks, comprehensive nationwide studies comparing migraine likelihood between statin users and controls are lacking. Our nested case-control study within the Korean National Health Insurance Service-Health Screening Cohort (2002-2019) investigated this association using 38,957 migraine patients and 155,828 controls, considering migraine subtypes (with/without aura) and statin types (lipophilic vs. hydrophilic). Using propensity score matching and adjusting for confounders, statin use was linked to reduced migraine likelihood overall (odds ratio (OR) 0.93), particularly for migraines with aura (OR 0.75) and without aura (OR 0.94). Lipophilic statins were effective for both subtypes, while hydrophilic statins mainly reduced the likelihood of migraines without aura. Subgroup analyses showed consistent benefits across demographics, but varied effectiveness based on weight, smoking, alcohol use, hemoglobin levels, and dyslipidemia history. In summary, this nationwide cohort study suggests that statin use may reduce migraine likelihood among Korean adults across diverse demographics and clinical profiles, but varied effectiveness based on certain lifestyle and comorbidity factors underscores the importance of considering individual patient profiles when assessing the potential benefits of statin therapy for migraine prevention.

Association of lipid-lowering agent use and dry eye disease: A nationwide matched case-control study in Taiwan, 2002-2016.

PURPOSE: The purpose of this study is to evaluate the association between lipid-lowering agent use and the risks of diagnosed dry eye disease (DED). METHODS: This retrospective, case-control study included 780 786 patients who received lipid-lowering agents in 2002-2016, of which 17 409 were newly diagnosed with DED during a ≥2-year follow-up period. These patients were matched 1:4 with control participants for age, sex, and comorbidities. Separate odds ratios (OR) were calculated for DED and each of statin and fibrate use. RESULTS: Statin users had significantly higher odds of DED (adjusted OR = 1.12; 95% confidence interval (CI) = 1.08-1.16, p < 0.0001) than nonusers. Fibrate users did not show higher odds of DED than nonusers (adjusted OR = 1.04; 95% CI = 0.99-1.10, p = 0.125). The lipophilic statin users did not show higher odds of DED compared with the hydrophilic statin users (adjusted OR = 0.99, 95% CI = 0.93-1.06, p = 0.729). Among statin users, the odds of DED did not differ significantly between patients receiving statin therapy for >180 days vs. ≤90 days or patients receiving statin therapy for 91-180 days vs. ≤90 days (adjusted OR = 1.00, p = 0.922; adjusted OR = 0.94, p = 0.541, respectively). The odds of DED were not statistically different among patients receiving low-intensity, moderate-intensity, and high-intensity of statin therapy. CONCLUSIONS: Patients receiving statin therapy had a higher DED risk than patients not receiving statin therapy. The type of statin, the duration, and the intensity of statin use were not significantly associated with DED risks. Further studies are required to identify the relevant factors related to DED risks with statin.

Association between statin use and the prognosis of hepatocellular carcinoma after resection: a nationwide cohort study.

Background: The majority of patients with hepatocellular carcinoma (HCC) following hepatic resection experience tumor recurrence. Statin use is associated with a reduced risk of HCC development; however, the association between statin use and the prognosis of HCC after resection remains unclear. We aimed to investigate the effect of statin use on the prognosis after hepatic resection among patients with HCC. Methods: A nationwide cohort study was performed with data from the National Health Insurance Service Database in Korea. Among 65,101 HCC patients who underwent hepatic resection between January 2002 and December 2017, we included 21,470 patients. For validation, a hospital-based cohort of 3366 patients with very early or early-stage HCC who received curative-intent hepatic resection between January 2010 and December 2018 was analyzed. Recurrence-free survival (RFS) and overall survival (OS) was compared between statin users and non-users. Findings: Among the nationwide cohort of 21,470 patients, 2399 (11.2%) used statins and 19,071 (88.8%) did not. Among the hospital cohort of 3366 patients, 363 (10.8%) used statins and 3003 (89.2%) did not. In the propensity score-matched nationwide cohort, statin users had better RFS (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.56-0.64; P < 0.001) and OS (HR, 0.49; 95% CI, 0.45-0.53; P < 0.001), with a duration-response relationship. In the propensity score-matched validation hospital cohort, statin treatment was significantly associated with better RFS (HR, 0.73; 95% CI, 0.59-0.90; P = 0.003) and OS (HR, 0.48; 95% CI, 0.32-0.72; P < 0.001). The beneficial effects of statins were more prominent in non-cirrhotics, tumors sized ≥3 cm, tumors with microscopic vascular invasion, or early HCC recurrence (<2 years after resection). Interpretation: Statin use was associated with a better prognosis in a population-based cohort of patients with HCC after hepatic resection, which was further validated in a large hospital-based cohort.

Corrigendum: Effective management of atherosclerosis progress and hyperlipidemia with nattokinase: A clinical study with 1,062 participants.

[This corrects the article DOI: 10.3389/fcvm.2022.964977.].

Effective management of atherosclerosis progress and hyperlipidemia with nattokinase: A clinical study with 1,062 participants.

Nattokinase (NK), known as a potent fibrinolytic and antithrombotic agent, has been shown to have antiatherosclerotic and lipid-lowering effects. However, data on human clinical studies are limited. In this clinical study involving 1,062 participants, our objective was to examine the efficacy of NK in atherosclerosis and hyperlipidemia and safety at the dose of 10,800 FU/day after 12 months of oral administration. Various factors, including lower doses that influence NK pharmacological actions, were also investigated. We found that NK at a dose of 10,800 FU/day effectively managed the progression of atherosclerosis and hyperlipidemia with a significant improvement in the lipid profile. A significant reduction in the thickness of the carotid artery intima-media and the size of the carotid plaque was observed. The improvement rates ranged from 66.5 to 95.4%. NK was found to be ineffective in lowering lipids and suppressing atherosclerosis progression at a dose of 3,600 FU/day. The lipid-lowering effect of NK was more prominent in subjects who smoked, drank alcohol, and subjects with higher BMI. Regular exercise further improved the effects of NK. Co-administration of vitamin K2 and aspirin with NK produced a synergetic effect. No noticeable adverse effects associated with the use of NK were recorded. In conclusion, our data demonstrate that atherosclerosis progression and hyperlipidemia can be effectively managed with NK at a dose of 10,800 FU/day. The lower dose of 3,600 FU per day is ineffective. The dose of 10,800 FU/day is safe and well tolerated. Some lifestyle factors and the coadministration of vitamin K2 and aspirin lead to improved outcomes in the use of NK. Our findings provide clinical evidence on the effective dose of NK in the management of cardiovascular disease and challenge the recommended dose of 2,000 FU per day.

Hypoglycemic, lipid lowering and antioxidant activities in root extract of Anthocephalus indicus in alloxan induced diabetic rats.

The present study was carried out to evaluate the hypoglycemic, lipid lowering and antioxidant activities in root extract of Anthocephalus indicus (A indicus) in alloxan inducd diabetic rats. Oral administration of ethanol extract of root (500mg/ kg body weight) for 21 days resulted in significant decrease in the levels of blood glucose, triglycerides, total cholesterol, phospholipid and free fatty acids. Furthermore, the root extract (100-400µg) inhibited the generation of superoxide anions and hydroxyl radicals, in both enzymic and non-enzymic systems, in vitro. The result of the present study demonstrated hypoglycemic, lipid lowering and antioxidant activities in root extract of A indicus, which could help in prevention of diabetic dyslipidemia and related diseases.

Acute toxicological effects on the earthworm Eisenia fetida of 18 common pharmaceuticals in artificial soil.

Following soil applications of recycled water and biosolids, pharmaceutical residues can eventually enter the terrestrial environment. In vitro and in vivo assays have largely focused on the acute ecotoxicity of these compounds in aquatic systems. However, studies on the ecotoxicological effects of pharmaceuticals in soil biota are especially scarce. The aim of this study was to investigate the acute toxicity of 18 pharmaceuticals (4 NSAIDs, 5 blood lipid-lowering agents, 6 ß-blockers and 3 antibiotics) that are usually found in the environment by using an Eisenia fetida bioassay. In addition, the presence of these pharmaceuticals in artificial soil was verified at the end of the test. Our results indicate that seven of the studied drugs cause acute adverse effects in E. fetida, in particular, the NSAIDs and the blood lipid-lowering agents. Ibuprofen (LC50=64.80 mg/kg) caused the highest acute toxicity for all tested compounds, followed by diclofenac (LC50=90.49 mg/kg) and simvastatin (LC50=92.70 mg/kg). Other tested pharmaceuticals from NSAIDs and blood lipid-lowering families have toxicity effects, from a LC50=140.87 mg/kg for gemfibrozil to 795.07 mg/kg for lovastatin. Atorvastatin, bezafibrate, ß-blockers and antibiotics showed no detectable lethality in E. fetida. The four NSAIDs showed evidence of modification of their original chemical structure after 14 days so the detected toxicity may be due to the original product as well as their degradation products. The three blood lipid-lowering agents seem to be more stable in soil. From an environmental perspective, the lethal concentrations of the tested drugs are much greater than those reported in wastewater and biosolids, therefore acute toxic effects may be improbable. However, little is known about the accumulation of these substances in soils after regular applications, so accumulative and chronic effects cannot be excluded. Moreover, more studies are needed to determine the role of the degradation products of these pharmaceuticals on terrestrial toxicity.
