Randomized trials suggest that statin treatment may lower blood pressure and influence cardiovascular autonomic function (CVAF), but the impact of duration of usage, discontinuation, and adherence to this therapy is unknown. We examined these issues with regard to blood pressure (BP)-related variables in a large, population-based study. Participants were 4942 adults (58% male; aged 50-84 years): 2179 on statin treatment and 2763 untreated. Days of utilization, adherence (proportion of days covered ≥0.8), and discontinuation (non-use for ≥30 days immediately prior to BP measurement) of three statins (atorvastatin, pravastatin, and simvastatin) over a period of up to 2 years was monitored retrospectively from electronic databases...

OBJECTIVES: Clinician utilization of the 2013 cholesterol lowering guidelines remains variable and unknown. We sought to examine statin prescribing patterns and compare rates among specialists who treat high-risk cardiovascular patients admitted to the hospital. METHODS: We retrospectively (via chart review) examined four specialty groups: (i) Cardiology, (ii) Cardiovascular or Vascular (CV) Surgery, (iii) Neurology, and (iv) Internal Medicine. Adult patients were included based on a discharge diagnosis of acute coronary syndrome, coronary artery bypass graft surgery, carotid endarterectomy, acute ischemic stroke, transient ischemic attack, or high-risk chest pain...

Sacubitril/valsartan (LCZ696) has been approved for the treatment of heart failure. Sacubitril is an in vitro inhibitor of OATPs. In clinical studies, LCZ696 increased atorvastatin Cmax by 1.7-fold and AUC by 1.3-fold, but had little or no effect on simvastatin or simvastatin acid exposure. A PBPK modelling approach was applied to explore the underlying mechanisms behind the statin-specific LCZ696 drug interaction observations. The model incorporated OATP-mediated clearance (CLint,T) for simvastatin and simvastatin acid to successfully describe the PK profiles of either analyte in the absence or presence of LCZ696...

CYP enzymes and hOATP1B1 are reported to be involved in the pharmacokinetics of lobeglitazone (LB), a new PPARγ agonist. Atorvastatin (ATV), a substrate for CYP3A and hOATP1B1, is likely to be co-administered with LB in patients with the metabolic syndrome. We report herein on a study of potential interactions between LB and ATV in rats. When LB was IV-administered with ATV, the systemic clearance (CL; 2.67 ± 0.63 mL/min/kg) and volume of distribution at steady-state (Vss; 289 ± 20 mL/kg) for LB remained unchanged, compared to those of LB without ATV (CL, 2...

Currently available antiepileptic drugs (AEDs) fail to control seizures in 30% of patients. Genomics-based drug repurposing (GBR) offers the potential of savings in the time and cost of developing new AEDs. In the current study, we used published data and software to identify the transcriptomic signature of chornic temporal lobe epilepsy and the drugs that reverse it. After filtering out compounds based on exclusion criteria, such as toxicity, 36 drugs were retained. 11 of the 36 drugs identified (>30%) have published evidence of antiepileptic efficacy (for example, curcumin) or antiepileptogenic affect (for example, atorvastatin) in recognised rodent models or patients...

Acute kidney injury (AKI) often occurs as a result of ischemia-reperfusion (IR). Previous studies have demonstrated that inflammation is an important contributor to AKI. Atorvastatin (ATO) possesses anti‑inflammatory properties and has been demonstrated to exert protective effects against renal IR injury (IRI). However, the underlying mechanism requires further study. In the present study, a rat model of renal IRI was successfully established. Consistent with the results of a previous study, ATO significantly attenuated IRI, which was supported by a decrease in serum creatinine and an increase in creatinine clearance rate, as well as alleviated pathological alterations in renal tubular cells...

Statins constitute a class of medications commonly used in the treatment of elevated cholesterol. However, in experimental studies statins also have other non-cholesterol mediated mechanisms of action, which may have neuroprotective effects. The purpose of this study was to determine if administration of atorvastatin for 7 days after injury would improve neurological recovery in patients with mild traumatic brain injury (mTBI). The hypothesis was that atorvastatin administration would reduce post-concussion symptoms and also that atorvastatin administration for one week post-injury would be safe...
