Impacts of a multipurpose outpatient hospital pharmacy in the framework of 3P medicine.

Challenge in the framework of Predictive Preventive and Personalised Medicine: In recent years, we have been witnessing a change in the performance of hospital pharmacists, aimed at increasing their participation in the pharmacotherapeutic process of patients. The drug cycle, characterised as multidisciplinary, is very complex. It is essential for the multidisciplinary team to have a broad vision of the medication system in order to guarantee safety and quality.Considering the challenges of current healthcare systems and paradigm shift from reactive to predictive medicine, a new professional environment should be created to promote the implementation of Predictive, Preventive and Personalised Medicine in healthcare. Objectives and study design: To optimise care times in multipurpose outpatient hospital both in the preparation of ready-to-use medications and in the dispensing of medications for home treatment.To increase the confidence and value of hospital pharmacists in the process of patient and family care.The design of the study was carried out by the following:-Coordinating the schedules of the multi-pathology day hospital with the software and records of Medication Preparation in the pharmacy service.-Opening a Pharmacy Outpatient Clinic associated with the multi-pathology day hospital.-Planning and scheduling patient treatments. Achievements: With the implementation of this programme, the visibility of hospital pharmacists in the multidisciplinary team was increased.This Pharmacy Outpatient Clinic allowed the coordination of the pharmaceutical care process in the day hospital.This project increased the credibility of the Pharmacy Service in the improvement of the integral process of the medicine. Predictive approach: The presence of pharmacists in the multi-pathology day hospital has a predictive approach. A change is made in the workflow that allows to generate a speed of intervention by acting before prescribing, dispensing and administering the treatment to the patient. Targeted prevention: The presence of pharmacists in the multipurpose day hospital unit and their collaboration with other professionals and the patient bring about a selective prevention that decreases the possibility of medication errors occurring. Personalisation of medical services: With the individualised dispensing of treatments, a step forward is taken in the personalisation of medical services, which avoids medication errors in labelling and administration and improves safety in the overall medication circuit in the hospital.

Cognitive Function with PCSK9 Inhibitors: A 24-Month Follow-Up Observational Prospective Study in the Real World-MEMOGAL Study.

INTRODUCTION: The cognitive safety of monoclonal antibody proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) has been established in clinical trials, but not yet in real-world observational studies. We assessed the cognitive function in patients initiating PCSK9i, and differences in cognitive function domains, to analyze subgroups by the low-density lipoprotein cholesterol (LDL-C) achieved, and differences between alirocumab and evolocumab. METHODS: This has a multicenter, quasi-experimental design carried out in 12 Spanish hospitals from May 2020 to February 2023. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). RESULTS: Among 158 patients followed for a median of 99 weeks, 52% were taking evolocumab and 48% alirocumab; the mean change from baseline in MoCA score at follow-up was + 0.28 [95% CI (- 0.17 to 0.73; p = 0.216)]. There were no significant differences in the secondary endpoints-the visuospatial/executive domain + 0.04 (p = 0.651), naming domain - 0.01 (p = 0.671), attention/memory domain + 0.01 (p = 0.945); language domain - 0.10 (p = 0.145), abstraction domain + 0.03 (p = 0.624), and orientation domain - 0.05 (p = 0.224)-but for delayed recall memory the mean change was statistically significant (improvement) + 0.44 (p = 0.001). Neither were there any differences in the three stratified subgroups according to lowest attained LDL-C level-0-54 mg/dL, 55-69 mg/dL and ≥ 70 mg/dL; p = 0.454-or between alirocumab and evolocumab arms. CONCLUSION: We did not find effect of monoclonal antibody PCSK9i on neurocognitive function over 24 months of treatment, either in global MoCA score or different cognitive domains. An improvement in delayed recall memory was shown. The study showed no differences in the cognitive function between the prespecified subgroups, even among patients who achieved very low levels of LDL-C. There were no differences between alirocumab and evolocumab. REGISTRATION: ClinicalTtrials.gov Identifier number NCT04319081.

Development of a carbocysteine 10% + urea 5% cream for the topical treatment of congenital ichthyosis.

OBJECTIVE: Optimization of a topical formula of N-acetylcysteine and urea for  the topical treatment of ichthyosis. METHOD: We reviewed the chemical structure of the N-acetylcysteine molecule  and its metabolic processes. A search was conducted of possible alternative  molecules with a chemical structure similar to that of N-acetylcysteine that  could have improved organoleptic properties. The following databases were  used: PubChem®, Botplus®, the Drug Information Centre of the Spanish  Agency of Medicines and Medical Devices. The molecule selection criteria were  as follows: structural similarity, same therapeutic group, same mechanism of  action, same authorized indication, absence of unpleasant smell, and being  marketed as raw material in Spain. To complete the pharmaceutical  development and validation of the compound, several tests and controls were  conducted following the emulsion production procedure of the National  Formulary. In order to establish the validity period, we followed the  recommendations of the "Guide to Good Drug Preparation Practices in Hospital  Pharmacy Services". RESULTS: N-acetylcysteine has a free sulfhydryl group, which is responsible for  its smell, and undergoes deacetylation. Its main metabolites are cystine and  cysteamine. The following molecules were assessed: cystine, cysteamine,  carbocisteine, cysteine and methionine. Carbocisteine was selected because it met all the selection criteria. Carbocisteine is  ractically insoluble in water and soluble in mineral acids and alkaline hydroxides solutions. Unlike N-acetylcysteine, it does not have a fetid smell. It reaches its  maximum stability at pH 5.5 to 7.5. The composition of the compound (100 g)  was as follows: carbocisteine (10 g), urea (5 g), glycerine (15 g), water (44  mL), sodium hydroxide (1 g), and Neo PCL® Oil/Water (O/W) (25 g). It has an expiration period of 30 days. The organoleptic characteristics, emulsion type,  and pH remained stable within the established expiration period. The  arbocisteine compound has been incorporated into the group of topical  treatments available for the treatment of patients with ichthyosis in our  hospital. CONCLUSIONS: The carbocisteine molecule is a good therapeutic alternative that  lacks the unpleasant smell of N-acetylcysteine. The  arbocisteine compound developed has been included as topical treatment for  ichthyosis due to its tolerability, acceptability, and effectiveness in the  treatment of patients affected by this genodermatosis.

Statins most used were rosuvastatin (34.1%) and atorvastatin (20.5%). Baseline value of LDL-c was 148mg/dL and the follow-up value was 71mg/dL. The baseline value of patients treated with alirocumab (N=43) was 144mg/dL and 73mg/dL in the follow-up. With evolocumab (N=46) was 151mg/dL in basaline and 69mg/dL in follow-up. The LDLc- reduction was 51.21% with evolocumab and 51.05% with alirocumab. 43.1% of the patients showed values >70mg/dL in six month time; 19.4% between 69mg/dl and 55mg/dL and 37.5% <55mg/dL. 58.3% of the patients achieved a reduction >50% of LDL-c. The adverse events were: injection point reaction (N=2), myalgias (N=1), flu-like symptoms (N=1) and neurocognitive worsening (N=1). CONCLUSIONS: (1) Despite the number of prescriptions was reduced because of the pandemic, the lipid control was not affected. (2) Half of the patients treated with PSCK9i is due to statins intolerance and the 86% is for secondary prevention. (2) The reduction results were similar to pivotal clinical trials. Despite this, 39% of the total of the patients and 60% of patients with dual teraphy did not reach the goal of ESC/EAS guidelines (<55mg/dL and/or reduction>50%). There were not significant differences between evolocumab and alirocumab: 51.21% vs 51.05% (P=.972). (3) There were not any adverse events of special interest. The possible neurocognitive worsening will be studied as the primary endpoint once the MEMOGAL study has been completed.

Objective: Dimethyl fumarate is a medication approved for the treatmentof relapsing-remitting multiple sclerosis. The purpose of the study was toevaluate the safety and persistence of dimethyl fumarate in clinical practice and analyze the occurrence of lymphopenia is patients treated withdimethyl fumarate over a period of at least 6 months.Method: This is a retrospective longitudinal observational study carriedout between August 2015 and March 2019. The study cohort was madeup of patients who had been treated with dimethyl fumarate for at least6 months. Lymphocyte counts were recorded at different points of time(pre-treatment, at 3, 6, 12 months, and at the end of the study period). Theevolution of lymphopenia was evaluated by means of a logistic regressionstatistical model. An analysis was performed of the relationship betweena decreased lymphocyte count over the first 6 months of treatment andthe development, by the end of the study, of grade II-III lymphopenianecessitating discontinuation of dimethyl fumarate. Other safety indicatorswere also evaluated including adverse events and interruptions or discontinuations of treatment. Persistence was determined by measuring the timeto discontinuation of treatment.Results: The study included a total of 55 patients, of whom 80% werefemale. The most common adverse events were lymphopenia (27), rubefaction (16), digestive symptoms (11), fatigue (9), headache (3) and sleepdisturbances (2). Eleven subjects interrupted/discontinued their treatment during the study period; reasons were as follows: pregnancy (2), personal decision (2), John Cunningham virus infection (1), allergy to the drug(2), and lymphopenia (4). Median duration of treatment was 23 months(4-43 months). A statistically significant association was found betweena lower lymphocyte count over the first 6 months of treatment and thedevelopment of severe lymphopenia by the end of the study [OR = 1.34(1.27-11.41); 95% CI (p = 0.001)]. )(AU)

Effectiveness, Safety, and Adherence to Treatment of Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitors in Real Practice.

PURPOSE: To evaluate the effectiveness, adverse reactions, and adherence to treatment of hypolipidemic inhibitors of proprotein convertase subtilisin/kexin type 9 (PCSK9is) in a context of real clinical practice. METHODS: We present an observational, retrospective, descriptive, multicenter study of patients with hypercholesterolemia who began treatment with PCSK9is between January 2017 and December 2019, with a minimum treatment period of 3 months. The main variable we recorded was the frequency of cardiovascular events (cardiovascular death, myocardial infarction, stroke, coronary revascularization, and hospitalization for unstable angina) in patients treated with PCSK9is. We recorded patient demographic characteristics and cardiovascular risk factors at onset of treatment as well as LDL-C levels and their reductions at 3, 6, 12, and 24 months. We calculated adherence to treatment and recorded the adverse reactions during treatment. FINDINGS: A total of 154 patients were studied, 64 (41.6%) of whom were treated with alirocumab and 90 (58.4%) with evolocumab. The initial dose of alirocumab was 75 mg every 14 days in 48 patients (75%) and 150 mg eery 14 days in 16 (25%). All patients who in the evolocumab group received a dose of 140 mg every 14 days. The mean (SD) basal LDL-C level was 159.6 (50.1) mg/dL, the level at 3 months was 87.9 (49.9) mg/dL (mean [SD] decrease, 44.5% [28.2%]), the level at 6 months was 86.7 (49.2) mg/dL (mean [SD] decrease, 46.3% [25.6%]), and the level at 12 months was 80.5 (41.4) (mean [SD] decrease, 48.9% [23.0%]). These values were maintained at 24 months (mean [SD], 80.3 [41.8] mg/dL; mean [SD] decrease, 47.9% [27.8%]). The percentage decrease of LDL-C for both drugs was approximately 50%, which was maintained until 24 months after treatment. Six patients (3.9%) presented with some cardiovascular event: acute myocardial infarction (2 [1.3%]), stroke (1 [0.65%]), coronary revascularization (1 [0.65%]), and hospitalization for unstable angina (2 [1.3%]). We did not see any adverse reactions related to PCSK9i treatment in 76.5% of patients. In the first 6 months, adherence to treatment with PCSK9is, measured as the possession ratio, was a mean (SD) of 99.4% (3.9%). In the rest of the study period (6-24 months), the mean (SD) adherence to treatment was 99.2% (4.7%). IMPLICATIONS: The frequency of cardiovascular events in patients treated with PCSK9is was low and occurred despite adequate adherence to treatment (100% possession ratio) with PCSK9is and concomitant treatment with other hypolipidemics. The effectiveness of PCSK9is is similar to that referred to in other published studies with PCSK9is, and this was maintained in the long term (24 months) with few adverse events, all of which were mild.

Safety and persistence of dimethyl fumarate as a treatment for relapsing-remitting multiple-sclerosis.

OBJECTIVE: Dimethyl fumarate is a medication approved for the treatment of relapsing-remitting multiple sclerosis. The purpose of the  study was to evaluate the safety and persistence of dimethyl fumarate in  clinical practice and analyze the occurrence of lymphopenia is patients  treated with dimethyl fumarate over a period of at least 6 months. METHOD: This is a retrospective longitudinal observational study carried out between August 2015 and March 2019. The study cohort was  made up of patients who had been treated with dimethyl fumarate for at  least 6 months. Lymphocyte counts were recorded at different points of  time (pre-treatment, at 3, 6, 12 months, and at the end of the study  period). The evolution of lymphopenia was evaluated by means of a  logistic regression statistical model. An analysis was performed of the  relationship between a decreased lymphocyte count over the first 6  months of treatment and the development, by the end of the study, of  grade II-III lymphopenia necessitating discontinuation of dimethyl  fumarate. Other safety indicators were also evaluated including adverse  events and interruptions or discontinuations of treatment. Persistence was  determined by measuring the time to discontinuation of treatment. RESULTS: The study included a total of 55 patients, of whom 80% were female. The most common adverse events were lymphopenia (27),  rubefaction (16), digestive symptoms (11), fatigue (9), headache (3) and  sleep disturbances (2). Eleven subjects interrupted/discontinued their  treatment during the study period; reasons were as follows: pregnancy  (2), personal decision (2), John Cunningham virus infection (1), allergy to  the drug (2), and lymphopenia (4). Median duration of treatment was 23  months (4-43 months). A statistically significant association was found  between a lower lymphocyte count over the first 6 months of treatment  and the development of severe lymphopenia by the end of the study [OR  = 1.34 (0.35-2.60); 95% CI (p = 0.001)]. CONCLUSIONS: The adverse events observed in the present study are in line with those reported in previous analyses. Lymphopenia was the  most common adverse event. The persistence of the medication was  similar to that found in pivotal trials. The significant association found  between a decreased lymphocyte count over the first 6 months of  treatment and the development of severe lymphopenia by the end of the  study suggests a connection between both variables, which could be  instrumental in being able to predict and even prevent the occurrence of  such lymphopenias.

Objetivo: Dimetilfumarato es un fármaco autorizado en el tratamiento de  la esclerosis múltiple recurrente-remitente. El objetivo es evaluar la seguridad y persistencia del dimetilfumarato en la práctica clínica, y  analizar la evolución de las linfopenias en pacientes en tratamiento con  dimetilfumarato un mínimo de 6 meses.Método: Estudio observacional, longitudinal, retrospectivo entre agosto de 2015 y marzo de 2019. Se incluyeron todos los pacientes en tratamiento durante un periodo mínimo de 6 meses. Se recogieron los  datos de recuento linfocitario a diferentes tiempos: pretratamiento, a los  3, 6, 12 meses y al final del periodo de estudio. Como modelo estadístico  se utilizó la regresión logística para analizar la evolución de las linfopenias. Se estudió la relación entre el descenso del recuento  linfocitario los primeros 6 meses de tratamiento y el desarrollo a tiempo  final del estudio de linfopenias grado II/III que podrían ser motivo de  suspensión. Además, se evaluaron otros indicadores de seguridad:  reacciones adversas, suspensiones y abandonos de tratamiento. Para el  análisis de la persistencia se contabilizaron los meses transcurridos desde  el inicio hasta la suspensión del tratamiento.Resultados: Se incluyeron 55 pacientes. El 80% fueron mujeres. Las reacciones adversas más frecuentes fueron: linfopenia (27),  rubefacción (16), molestias digestivas (11), fatiga (9), cefalea (3) y  alteraciones del sueño (2). Durante el periodo considerado hubo 11  abandonos/suspensiones de tratamiento, las razones fueron: embarazo  (2), decisión propia (2), infección por virus John Cunningham (1), alergia  al fármaco (2) y linfopenia (4). La mediana de duración de tratamiento fue de 23 meses (4-43 meses). Se encontraron diferencias estadísticamente significativas en el análisis de la relación entre el descenso de linfocitos los primeros 6 meses de tratamiento y el desarrollo de linfopenias graves a  tiempo final del estudio, con una odds ratio de 1,34, un intervalo de  confianza del 95% de 0,35-2,60 y un valor de p de 0,001.Conclusiones: Las reacciones adversas observadas siguen la línea de ensayos y estudios previos. La linfopenia fue la reacción adversa más frecuente. Los resultados muestran una persistencia del tratamiento  similar a la de los ensayos pivotales. Las diferencias significativas  observadas entre la reducción de linfocitos los primeros 6 meses de  tratamiento y el desarrollo de linfopenias graves al final del estudio,  sugieren una relación entre ambas variables y la posibilidad de predecir y  evitar la aparición de dichas linfopenias.

Determinación del pH como criterio de calidad en la elaboración de fórmulas magistrales orales líquidas / pH determination as a quality standard for the elaboration of oral liquid compounding formula

Objetivo: El pH es un factor crítico para todos aquellos medicamentos que se encuentran en formas líquidas acuosas, ya que puede ejercer un efecto sobre la solubilidad del principio activo condicionando la estabilidad de los medicamentos, la tolerancia biológica de la forma farmacéutica y la actividad del principio activo. El objetivo de este trabajo es establecer el rango óptimo de pH de las fórmulas orales líquidas más frecuentemente elaboradas en el Servicio de Farmacia para estandarizar e incorporar dicho valor en los protocolos normalizados de trabajo como criterio de control de calidad. Método: El estudio se desarrolló en tres fases. En una primera fase se realizó un estudio retrospectivo de los registros de elaboración de las fórmulas orales líquidas elaboradas, al menos 5 veces, desde enero de 2015 a diciembre de 2016 en nuestro Servicio de Farmacia, y se calculó el valor medio y la desviación estándar de los valores de pH registrados para cada fórmula. En una segunda fase se realizó una búsqueda bibliográfica para conocer el pH de máxima estabilidad del principio activo y comprobar si esta característica se registra como requisito de control de calidad en los procedimientos descritos en los formularios de referencia. En una tercera fase se comprobó si los pH determinados se correspondían con el de máxima estabilidad descrito en la literatura y se establecieron rangos de aceptación. Resultados: Se revisaron un total de 31 fórmulas (14 soluciones/17 suspensiones). Se conocía el valor del pH de máxima estabilidad de 19 (61,3%) de los principios activos y/o fórmulas orales líquidas evaluadas, de las cuales 15 (78,9%) se encontraban dentro del mismo y las 4 restantes (21,1%) presentaron una desviación estándar de ± 0,5 con respecto al valor de pH referenciado en la bibliografía. El rango de pH para un mismo procedimiento normalizado de trabajo oscilaba entre 0,32 y 1,51. Se estableció como control de calidad un rango de aceptación de pH de ± 0,75

Objective: pH is a critical factor for all those medications prepared as aqueous liquid forms, because it has an impact on the solubility of the molecule, determining the stability of medications, the biological tolerability of the formulation, and the activity of the molecule. The objective of this study is to determine the optimum pH range for the oral liquid formulations more frequently prepared at the Pharmacy Unit, in order to standardize and incorporate said value into the standard protocols of action as a quality control criterion. Method: The study was conducted in three stages. The first stage consisted in a retrospective study of the records of preparation of those oral liquid formulations prepared at least 5 times since January, 2015 to December, 2016, in our Pharmacy Unit; the main value and standard deviation of the pH values recorded for each formulation were calculated. In a second stage, there was a bibliographic search in order to understand the pH for the maximum stability of the molecule, and to confirm if this characteristic was recorded as a requirement for quality control in the procedures described in the formulation guidelines. In the third stage, it was confirmed if the pH values determined coincided with the maximum stability pH described in literature, and acceptance ranges were established. Results: In total, 31 formulations were reviewed (14 solutions / 17 suspensions). The maximum stability pH value was known for 19 (61.3%) of the molecules and/or oral liquid formulations evaluated; 15 (78.9%) of these were within this range, and the remaining 4 (21.1%) presented a standard deviation of ± 0.5 regarding the pH value referenced in the bibliography. The pH range for the same standard work procedure ranged between 0.32 and 1.51. An acceptance pH range of ± 0.75 was determined as quality control

Utilización del recambio plasmático como herramienta terapéutica en la práctica clínica / Use of plasma exchange as therapeutic tool in clinical practice

Objetivo: Describir la utilización del recambio plasmático terapéutico (RPT) en distintas patologías y su ajuste a las guías internacionales de referencia. Método: Estudio observacional, descriptivo y retrospectivo en pacientes que recibieron plasmaféresis entre enero de 2014 y diciembre de 2015. Se analizó la adecuación de su indicación según la bibliografía consultada, así como la respuesta obtenida. El Servicio de Hematología estableció la indicación, el volumen plasmático a recambiar, el número de sesiones y la periodicidad según la enfermedad de base y su evolución clínica. Resultados: Diez pacientes (8 mujeres) entre 28 y 72 años de edad, recibieron RPT. Las patologías eran de origen neurológico (9 pacientes), enfermedad de Waldenström (1 paciente). La técnica utilizada fue centrifugación continua con albúmina 5% como líquido de reposición. Conclusiones: El RPT en los pacientes revisados se ajustó a las guías de referencia. No se observó correlación directa entre el grado de recomendación establecido por dichas guías y la respuesta obtenida. El número reducido de pacientes supone una limitación a la hora de extraer resultados concluyentes (AU)
