Lipid-lowering drug use in Italian primary care: effects of reimbursement criteria revision
2008
OBJECTIVE: To assess whether the prescribing pattern of lipid-lowering drugs (LLD) changed after reimbursement criteria revision in a general practice in southern Italy. METHODS: From the Caserta-1 Local Health Service database, 93 general practitioners (GPs) who had consistently sent data about their patients during the years 2003-2005 were recruited. Prevalence of use and incidence of new treatments were calculated for each year, stratified by three drug cohorts: statins, omega-3 fatty acids, and fibrates. Subanalyses by gender, age, and indication of use were performed. RESULTS: Overall, 1-year prevalence of LLD use increased from 2003 to 2004. After reimbursement criteria revision (Nove…
A focus on epidemiology of drug-induced liver injury: analysis of a prospective cohort
2017
OBJECTIVE: Drug-induced liver injury (DILI) is more often a challenge even for expert clinicians. Presently, there are limited data about the epidemiology, because the real incidence and prevalence of the disorder are underestimated, and further, sometimes the pharmacovigilance chain is unsuccessful as cases are largely underreported. We review available literature data and discuss our clinical experience regarding a prospective cohort of 185 patients with a diagnosis of DILI.MATERIALS AND METHODS: Significant papers were identified by literature search, and selected based on content including the epidemiology of DILI. By analyzing our prospective cohort, consecutively collected since Janua…
Interaction risk with proton pump inhibitors in general practice: significant disagreement between different drug-related information sources.
2006
Aims To compare information on drug–drug interactions (DDIs) reported on two standard drug-related information sources (Summary of Product Characteristics and Drugdex system by Micromedex), by assessing the prevalence and predictors of potential DDI with proton pump inhibitors (PPIs) in general practice. Methods From the ‘Caserta-1’ Local Health-Service database, 156 general practitioners (GPs) were recruited. From more than 180 000 individuals registered on their lists, we selected patients receiving co-prescription of PPI and medications at interaction risk, according to the Italian Summary of Product Characteristics (SPC) of PPI and Drugdex information, during the year 2003. Thereafter, …
Analysis of a possible association between oral lichen planus and drug intake. A controlled study
2010
Objectives: To investigate whether daily systemic and/or topical medication contributes to the development of oral lichen planus (OLP) lesions. Study Design: The study involved 110 OLP patients and 76 control subjects, matched by age, race and sex. The analyzed data included medical records, drug intake and topical medication. Criteria for analysis of drug intake included: (1) ATC-code drug classification; (2) number of different drugs used daily in the categories of monopharmacy (1 drug), minor polypharmacy (2 4 drugs), and major polypharmacy (> 5 drugs); and (3) drugs implicated in lichenoid reactions (DILRs). Results: Sixty (54.5%) of the 110 OLP patients reported daily medication (prior…
Prescription drug use during pregnancy in France: a study from the national health insurance permanent sample.
2017
International audience; PurposeTo provide an up-to-date account of drug prescription during pregnancy in France from 2011 to 2014 using the permanent sample of the French national computerized healthcare database and with a focus on recommended supplementations, fetotoxic drugs and teratogenic drugs.MethodsAll pregnancies identified by the International Classification of Diseases, 10th Revision codes list in the hospitalization database, lasting more than 9 weeks of amenorrhea and whose delivery occurred between 01/01/2011 and 12/31/2014, were included. Drugs delivered between the trimester before and until the end of the pregnancy were included. Drug exposure prevalence was calculated for …
Entrapment of an EGFR inhibitor into nanostructured lipid carriers (NLC) improves its antitumor activity against human hepatocarcinoma cells
2014
Background: In hepatocellular carcinoma (HCC), different signaling pathways are de-regulated, and among them, the expression of the epidermal growth factor receptor (EGFR). Tyrphostin AG-1478 is a lipophilic low molecular weight inhibitor of EGFR, preferentially acting on liver tumor cells. In order to overcome its poor drug solubility and thus improving its anticancer activity, it was entrapped into nanostructured lipid carriers (NLC) by using safe ingredients for parenteral delivery. Results: Nanostructured lipid carriers (NLC) carrying tyrphostin AG-1478 were prepared by using the nanoprecipitation method and different matrix compositions. The best system in terms of mean size, PDI, zeta…
Pharmacokinetic evaluation of oral fenofibrate nanosuspensions and SLN in comparison to conventional suspensions of micronized drug.
2007
An increasing number of newly developed drugs show bioavailability problems due to poor water solubility. Formulating the drugs as nanosuspensions may help to overcome these problems by increasing saturation solubility and dissolution velocity. In the present study the bioavailability of the poorly soluble fenofibrate following oral administration was investigated in rats. Four formulations were tested: a nanosuspension type DissoCube(R), one solid lipid nanoparticle (SLN) preparation and two suspensions of micronized fenofibrate as reference formulations, one suspension in sirupus simplex and a second in a solution of hydroxyethy-cellulose in physiological saline. Both colloidal drug deliv…
Polypharmacy and the risk of drug-drug interactions and potentially inappropriate medications in hospital psychiatry.
2021
PURPOSE The aim of this study was to analyze the epidemiology of polypharmacy in hospital psychiatry. Another aim was to investigate predictors of the number of drugs taken and the associated risks of drug-drug interactions and potentially inappropriate medications in the elderly. METHODS Daily prescription data were obtained from a pharmacovigilance project sponsored by the Innovations Funds of the German Federal Joint Committee. RESULTS The study included 47 071 inpatient hospital cases from eight different study centers. The mean number of different drugs during the entire stay was 6.1 (psychotropic drugs = 2.7; others = 3.4). The mean number of drugs per day was 3.8 (psychotropic drugs …
Hypolipidaemic effects of fenofibrate are not altered by mildronate-mediated normalization of carnitine concentration in rat liver.
1999
The five-fold higher carnitine content in the liver of fenofibrate-treated rats addresses the question about the possible role of this enhancement in the hypolipidaemic effect of the drug and the underlying mechanisms. When fenofibrate was administered with mildronate (a gamma-butyrobetaine hydroxylase inhibitor) in suitable amount, the content in carnitine was found to be normalized in liver. However, triglyceride contents of liver and serum were then at least as low as in rats treated by fenofibrate only. When carnitine concentration was lowered by mildronate to the third of the normal value, a marked increase in triglycerides occurred both in liver and serum, while the five-fold increase…
Gefitinib in lung cancer therapy. Clinical results, predictive markers of response and future perspectives.
2009
Over the past few years, epidermal growth factor receptor has emerged as one of the most important targets in tumorgenesis and several drugs targeting signal transduction pathways have been developed. The first among these agents to be approved for the treatment of NSCLC was gefitinib, a potent, selective and reversible inhibitor of HER1/EGFR tyrosine kinase activity. The review summarizes its clinical development and the new therapeutic options, with particular focus on predictive markers of susceptibility to this drug.
