    In order to avoid separate injections, admixtures of drugs are frequently used in palliative care settings. There are different factors that can influence the compatibility and stability of the mixture: drug type, concentration, solvent, container, temperature and light. There are some mixtures of drugs with proven stability, but there is lack of evidence about the stability and compatibility of the combination of hyoscine N-butyl bromide and furosemide.Universidad de Málaga,Campus de Excelencia Internacional Andalucía Tec

    With the aim of controlling various symptoms, possible to use mixtures of different drugs within infusion devices. This should take into account the compatibility of the mixture. Factors influence the compatibility and stability of the mixtures are: drug type, concentration, solvent, temperature and light. When evaluating the compatibility of the mixtures for infusion for subcutaneous via is important to consider infusion devices used and the conditions of light and temperature should simulate as far as possible the conditions in practice assistance. There are diverse studies that analyze the compatibility of drug mixtures, but there are still many possible combinations of drugs for which evidence is not available. The objective of this work is to study the compatibility and stability of several mixtures of haloperidol and morphine that can be used in solution for subcutaneous infusion

    Background: In order to avoid separate injections of different drugs, admixtures of opioids with other drugs used in palliative care are frequently used. There are different factors that can influence the compatibility and stability of the mixture: drug type, concentration, solvent, container, temperature and light. There are some mixtures of opioids with other drugs with proven stability, but there is lack of evidence about the stability and compatibility of the combination of morphine and furosemide. Purpose: To evaluate the compatibility and stability of the admixture morphine 1.0 mg/ml - furosemide 0.6 mg/ml in NaCl 0.9% stored at ambient room temperature under normal light for at least 30 days. Material and method: On study day 0, a mixture was prepared and diluted in NaCl 0.9% to obtain 1.0 mg/ml of morphine and 0.6 mg/ml of furosemide and stored at ambient room temperature under normal light. The concentration of each constituent drug was periodically determined using a HPLC-UV method. The drugs were chromatographed on a C18 reverse phase column; the mobile phase was acetonitrile-water 80:20 (v/v); flow rate 1.5 ml/min. Morphine and furosemide concentrations were determined at 235 nm by interpolation from the calibration curves prepared at (0, 1, 2, 5, 7, 9, 12, 15, 19, 23, 26, 30) days from the standards. Results and discussion: The admixture remained physically and chemically stable during study period, with no precipitation or colour change and non-significant loss of morphine or furosemide. Statgraphics centurion XVI program has been used to data treatment. Conclusion: Morphine and furosemide mixture diluted in NaCl 0.9% (concentration 1.0 and 0.6 mg/ml, respectively), is physically and chemically stable from at least 30 days.Universidad de Málaga, Campus de Excelencia Internacional Andalucía Tec

    Background and importance Different factors can influence the compatibility and stability of the mixture: drug type, concentration, solvent, container, temperature and light. There are some mixtures of drugs with proven stability, but there is a lack of evidence about the stability and compatibility of the combination of ondansetron and midazolam. The objective of this investigation was to study the compatibility and stability of a binary mixture of these drugs in solution for subcutaneous infusion in palliative care Aim and objectives To evaluate the compatibility and stability of two admixtures of ondansetron and midazolam at two different temperatures (25°C and 37°C). The concentrations of the admixtures were 0.1 g/L–0.1 g/L and 0.5 g/L–1.0 g/L in NaCl 0.9% stored in elastomeric infusors protected from light Material and methods Samples were prepared and diluted in NaCl 0.9% in elastomeric infusors in triplicate to obtain four different conditions of concentration and/or storage temperature (0.1 g/L–0.1 g/L; 0.5 g/L–1.0 g/L for ondansetron and midazolam, respectively, stored at temperatures of 25°C and 37°C). The concentration of each drug was periodically determined using HPLC-UV and UV-Vis spectrophotometry methods in the analytical chemistry laboratory between February and June 2019. Conditions: C18 column, mobile phase methanol: KH2PO40.05 M, adjusted to pH 3 with H3PO3 (60:40, v/v) delivered at a flow rate of 1.0 mL/min. The sample injection volume was 20 mL, and triplicate injections were performed for every sample. The signal was recorded over 14 min and the retention times were 4.1 min for ondansetron and 7.8 min for midazolam. Ondansetron and midazolam concentrations were determined at 254 nm. Results The stability of the admixtures diluted in NaCl 0.9% were as follow: ondansetron–midazolam (0.1 mg/mL–0.1 mg/mL and 0.5 mg/mL –1.0 mg/mL) were stable(retained >90% of their initial concentrations) for only 1 day at 25°C and 37°C, respectivelyUniversidad de Málaga.

    Optical techniques for chemical analysis are well established and sensors based on thesetechniques are now attracting considerable attention because of their importance in applications suchas environmental monitoring, biomedical sensing, and industrial process control. On the other hand,flow injection analysis (FIA) is advisable for the rapid analysis of microliter volume samples and canbe interfaced directly to the chemical process. The FIA has become a widespread automatic analyticalmethod for more reasons; mainly due to the simplicity and low cost of the setups, their versatility, andease of assembling. In this paper, an overview of flow injection determinations by using opticalchemical sensors is provided, and instrumentation, sensor design, and applications are discussed. Thiswork summarizes the most relevant manuscripts from 1980 to date referred to analysis using opticalchemical sensors in FIA

    Objective: To evaluate the stability of cabazitaxel diluted in 0.9% sodium chloride (NS) and stored in glass. Methods: A reverse-phase stability-indicating liquid chromatographic method was developed and validated before the study. The commercially available product was prepared according to the manufacturer’s instructions, and further diluted in NS to obtain concentrations of 0.120 mg/mL and 0.240 mg/mL cabazitaxel and stored in glass under refrigeration and at 25ºC, all of them protected from light. The concentration of cabazitaxel was evaluated over a period of 21 days. Results: Physical stability: The visual inspection of the stored samples to 25ºC (0.120 mg/mL and 0.240 mg/mL) indicated appearance of a white precipitate in both cases on the day 2 of study. In the case of the refrigerated samples, a similar precipitate appears on the day 6 of the study for the 0.240 mg/mL concentration and on the day 21 for 0.120 mg/mL concentration. Chemical stability: The samples that stay physically stable have been evaluated by HPLC method obtaining in all determinations a remaining percentage >95%. Solutions of cabazitaxel were subjected to a forced degradation analysis. Conclusion: Solutions of cabazitaxel 0.120 mg/mL prepared in NS and stored in glass retained more than 95% of the initial drug concentration when stored for one day at 25ºC and for twenty days at 4ºC. Solutions of cabazitaxel 0.240 mg/mL prepared in the same conditions retained more than 95% of the initial drug concentration when stored for one day at 25ºC and for two days at 4ºC.Junta de Andalucía.Ye
