    Abstract Purpose: The Pharmacy Service of the Infanta Leonor University Hospital acquires, compounds, distributes and dispenses more than 3000 L of methadone oral solution to Drug Addiction Patients Centers per year. Our purpose is to develop and validate an improved high performance liquid chromatography (HPLC) method to quantify methadone hydrochloride in a new oral solution with methylhydroxybenzoate (methylparaben) and propylhydroxybenzoate (propylparaben) to be implemented in physicochemical stability studies that allow to provide more information and even to increase the beyond-use date.
    Methods: A HPLC-Agilent
    Results: Chromatographic conditions were: flow rate 1.6 mL/min; mobile phase 55% acetonitrile and 45% sodium phosphate 25 mM (pH = 10); injection volume was 5 µL. The column was a Waters-XTerra™ RP18, maintained at 40 °C. DAD was λ = 254 nm. Retention times for methadone, methylparaben and propylparaben were 4.34, 0.70 and 0.88 min respectively. The method was linear (y = 284.3x - 97.8, r = 0.996). Instrumental precision was 0.33% for standards (n = 10); intra-assay precision 0.53% (n = 6) and inter-assay precision 1.95% (n = 12). The relative standard deviation percentage for accuracy was 1.28%. The recovery percentage was 101.5 ± 1.5%. LQ and LD were 2.18 µg/mL and 2.0 µg/mL respectively. The most destabilizing conditions were oxidizing and alkaline. The chromatograms confirmed no interference with the methadone signal.
    Conclusions: The HPLC method has proved to be valid and reproducible for methadone quantification in a new oral solution with methylparaben and propylparaben. This assay is a rapid, simple and reliable technique that can be used in daily analysis and physicochemical stability studies.

    Abstract Background: Hereditary fructose intolerance (HFI) is a rare metabolic disease caused by aldolase B deficiency. The aim of our study was to analyse excipient tolerability in patients with HFI and other related diseases and to design mobile and website health applications to facilitate the search for drugs according to their tolerance.
    Results: A total of 555 excipients listed in the Spanish Medicines Agency database (July 2023) were classified as suitable for HFI patients, suitable with considerations ((glucose and glucose syrup, intravenous sucrose, oral mannitol, polydextrose, gums and carrageenans, ethanol, sulfite caramel and vanilla), not recommended (intravenous mannitol) and contraindicated (fructose, oral sucrose, invert sugar, sorbitol, maltitol, lactitol, isomaltitol, fruit syrups, honey, sucrose esters and sorbitol esters). Glucose and glucose syrup were classified as suitable with considerations due to its possible fructose content and their potential endogenous fructose production. For other related intolerances, wheat starch was contraindicated and oatmeal was not recommended in celiac disease; oral lactose and lactose-based coprocessed excipient (Cellactose®) were not recommended in lactose intolerance; and glucose, invert sugar and oral sucrose were not recommended in diabetes mellitus. The applications were named IntoMed®. Results are listed in order of tolerability (suitable drugs appear first and contraindicated drugs at the end), and they are accompanied by a note detailing their classified excipients. If a drug contains excipients within different categories, the overall classification will be the most restrictive. The apps are also able to classify substances with the same criteria if they act as active ingredients. The tools exhibited good usability (82.07 ± 13.46 points on the System Usability Scale [range: 0-100]) on a sample of HFI patients, their families and health care professionals.
    Conclusions: IntoMed® is a tool for finding information about the tolerability of drugs according to excipients for patients with HFI and other related intolerances, with good usability. It is a fast and reliable system that covers the current excipient legislation and expands on it with other specific information: HFI patients should be alert for excipients such as mannitol (especially in intravenous drugs), fruit syrups, honey, sulfite caramel or vanilla. Glucose might contain or produce fructose, and special precaution is needed because of potential errors in their composition.

    Abstract In this article, we studied physicochemical and microbiological stability and determined the beyond-use date of two oral solutions of methadone in three storage conditions. For this, two oral solutions of methadone (10 mg/mL) were prepared, with and without parabens, as preservatives. They were packed in amber glass vials kept unopened until the day of the test, and in a multi-dose umber glass bottle opened daily. They were stored at 5 ± 3 °C, 25 ± 2 °C and 40 ± 2 °C. pH, clarity, and organoleptic characteristics were obtained. A stability-indicating high-performance liquid chromatography method was used to determine methadone. Microbiological quality was studied and antimicrobial effectiveness testing was also determined following European Pharmacopoeia guidelines. Samples were analyzed at days 0, 7, 14, 21, 28, 42, 56, 70, and 91 in triplicate. After 91 days of storage, pH remained stable at about 6.5-7 in the two solutions, ensuring no risk of methadone precipitation. The organoleptic characteristics remained stable (colorless, odorless, and bitter taste). The absence of particles was confirmed. No differences were found with the use of preservatives. Methadone concentration remained within 95-105% in all samples. No microbial growth was observed. Hence, the two oral methadone solutions were physically and microbiologically stable at 5 ± 3 °C, 25 ± 2 °C, and 40 ± 2 °C for 91 days in closed and opened amber glass bottles.

    Abstract In February 2018, Resolution 189/2018 was published in the Autonomous Community of Madrid with the objective of centralizing the  procedure for the acquisition, preparation, distribution, and dispensing of methadone to Centres for the Comprehensive Care of Drug Addiction Patients  within the Madrid Health Service under the responsibility of a Hospital Pharmacy  Service. The Hospital Pharmacy Service began this activity in March 2018. This is the first time that the comprehensive management of a methadone  maintenance plan has been centralized in an Hospital Pharmacy Service for the care of drug-dependent patients in the Autonomous Community of Madrid. At the beginning of the Project, the previous workflow was analysed, the pharmaceutical laboratory was adapted, and the methadone acquisition procedure was designed. A communication channel with the Centres  for the Comprehensive Care of Drug Addiction Patients was implemented and application forms were designed. Corresponding control procedures were established given that the medication under consideration was a narcotic. Standard procedures for the acquisition of methadone, of containers for personalized dosing in Centres for the Comprehensive Care of Drug Addiction  Patients, and transport routes were designed and contracted out through public  tender in compliance with the Public Administration Contract Law. A tender has  also been awarded for the implementation of a computerized management  system and automated dispensing systems, which are currently undergoing  installation. The pharmacotherapeutic protocol of the Methadone Maintenance Plan of the Autonomous Community of Madrid is also being updated. Over 18  months, 5,300 L of methadone solution have been prepared and 2,844 individual prescriptions have been dispensed. High levels of perceived satisfaction were  reported via a questionnaire administered to the Centre for the Comprehensive  Care of Drug Addiction Patients staff. The response rate was 92%. Overall  satisfaction was very satisfied/quite satisfied (91%) and satisfied (9%). These  results highlight the high level of satisfaction (quite satisfied or very satisfied:  81.8%) with the effectiveness and speed of resolution of incidents by the  Hospital Pharmacy Service staff. This process incorporates the knowledge and  experience of hospital pharmacists into this healthcare field, as well as taking  advantage of existing resources, facilities, and procedures. All these aspects lead to an efficient, effective, and safe approach to this clinical-care activity and  enable a change in the pharmacotherapeutic health care model for opioid- dependent patients.

    Abstract This study aimed to build an easily applicable prognostic model based on routine clinical, radiological, and laboratory data available at admission, to predict mortality in coronavirus 19 disease (COVID-19) hospitalized patients.
    Methods: We retrospectively collected clinical information from 1968 patients admitted to a hospital. We built a predictive score based on a logistic regression model in which explicative variables were discretized using classification trees that facilitated the identification of the optimal sections in order to predict inpatient mortality in patients admitted with COVID-19. These sections were translated into a score indicating the probability of a patient's death, thus making the results easy to interpret.
    Results: Median age was 67 years, 1104 patients (56.4%) were male, and 325 (16.5%) died during hospitalization. Our final model identified nine key features: age, oxygen saturation, smoking, serum creatinine, lymphocytes, hemoglobin, platelets, C-reactive protein, and sodium at admission. The discrimination of the model was excellent in the training, validation, and test samples (AUC: 0.865, 0.808, and 0.883, respectively). We constructed a prognostic scale to determine the probability of death associated with each score.
    Conclusions: We designed an easily applicable predictive model for early identification of patients at high risk of death due to COVID-19 during hospitalization.
