[The Raman Spectroscopy (RS): A new tool for the analytical quality control of injectable in health settings. Comparison of RS technique versus HPLC and UV/Vis-FTIR, applied to anthracyclines as anticancer drugs]. / La Spectroscopie Raman (SR) : un nouvel outil adapté au contrôle de qualité analytique des préparations injectables en milieu de soins. Comparaison de la SR aux techniques CLHP et UV/visible-IRTF appliquée à la classe des anthracyclines en cancérologie.

The study compares the performances of three analytical methods devoted to Analytical Quality Control (AQC) of therapeutic solutions formed into care environment, we are talking about Therapeutics Objects(TN) (TOs(TN)). We explored the pharmacological model of two widely used anthracyclines i.e. adriamycin and epirubicin. We compared the performance of the HPLC versus two vibrational spectroscopic techniques: a tandem UV/Vis-FTIR on one hand and Raman Spectroscopy (RS) on the other. The three methods give good results for the key criteria of repeatability, of reproducibility and, of accuracy. A Spearman and a Kendall correlation test confirms the noninferiority of the vibrational techniques as an alternative to the reference method (HPLC). The selection of bands for characterization and quantification by RS is the results of a gradual process adjustment, at the intercept of matrix effects. From the perspective of a AQC associated to release of TOs, RS displays various advantages: (a) to decide quickly (~2min), simultaneously and without intrusion or withdrawal on both the nature of a packaging than on a solvant and this, regardless of the compound of interest; it is the founder asset of the method, (b) to explore qualitatively and quantitatively any kinds of TOs, (c) operator safety is guaranteed during production and in the laboratory, (d) the suppression of analytical releases or waste contribute to protects the environment, (e) the suppression.of consumables, (f) a negligible costs of maintenance, (g) a small budget of technicians training. These results already show that the SR technology is potentially a strong contributor to the safety of the medication cycle and fight against the iatrogenic effects of drugs.

Home intravenous antibiotherapy and the proper use of elastomeric pumps: Systematic review of the literature and proposals for improved use.

Over several decades, the economic situation and consideration of patient quality of life have been responsible for increased outpatient treatment. It is in this context that outpatient antimicrobial treatment (OPAT) has rapidly developed. The availability of elastomeric infusion pumps has permitted prolonged or continuous antibiotic administration by dint of a mechanical device necessitating neither gravity nor a source of electricity. In numerous situations, its utilization optimizes administration of time-dependent antibiotics while freeing the patient from the constraints associated with infusion by gravity, volumetric pump or electrical syringe pump and, more often than not, limiting the number of nurse interventions to one or two a day. That much said, the installation of these pumps, which is not systematically justified, entails markedly increased OPAT costs and is liable to expose the patient to a risk of therapeutic failure or adverse effects due to the instability of the molecules utilized in a non-controlled environment, instability that necessitates close monitoring of their use. More precisely, a prescriber must take into consideration the stability parameters of each molecule (infusion duration, concentration following dilution, nature of the diluent and pump temperature). The objective of this work is to evaluate the different means of utilization of elastomeric infusion pumps in intravenous antibiotic administration outside of hospital. Following a review of the literature, we will present a tool for optimized antibiotic prescription, in a town setting by means of an infusion device.

Preparing and administering injectable antibiotics: How to avoid playing God.

The emergence of bacterial resistance and the lack of new antibiotics in the pipeline represent a public health priority. Maximizing the quality of antibiotic prescriptions is therefore of major importance in terms of adequate preparation and administration modalities. Adequate preparation prevents the inactivation of antibiotics and is a prerequisite to maximizing their efficacy (taking into account the pharmacokinetic/pharmacodynamic relationship) and to minimizing their toxicity. Many antibiotic guidelines address the choice of drugs and treatment duration but none of them exclusively address preparation and administration modalities. These guidelines are based on the available literature and offer essential data for a proper antibiotic preparation and administration by physicians and nurses. They may lead to a better efficacy and to a reduced antibiotic resistance. Such guidelines also contribute to a proper use of drugs and improve the interaction between inpatient and outpatient care for a better overall management of patients.
