ABSTRACT

BACKGROUND AND OBJECTIVE: Drug dosing should ideally be based on the drug concentrations at the target site, which, for most drugs, corresponds to the tissue. The exact influence of growth and development on drug tissue distribution is unclear. This systematic review compiles the current knowledge on the tissue distribution of systemically applied drugs in children, with the aim to identify priorities in tissue pharmacokinetic (PK) research in this population. METHODS: A systematic literature search was performed in the MEDLINE and Embase databases. RESULTS: Forty-two relevant articles were identified, of which 71% investigated antibiotics, while drug classes from the other studies were anticancer drugs, antifungals, anthelmintics, sedatives, thyreostatics, immunomodulators, antiarrhythmics, and exon skipping therapy. The majority of studies (83%) applied tissue biopsy as the sampling technique. Tonsil and/or adenoid tissue was most frequently examined (70% of all included patients). The majority of studies had a small sample size (median 9, range 1-93), did not include the youngest age categories (neonates and infants), and were of low reporting quality. Due to the heterogeneous data from different study compounds, dosing schedules, populations, and target tissues, the possibility for comparison of PK data between studies was limited. CONCLUSION: The influence of growth and development on drug tissue distribution continues to be a knowledge gap, due to the paucity of tissue PK data in children, especially in the younger age categories. Future research in this field should be encouraged as techniques to safely investigate drug tissue disposition in children are available.

ABSTRACT

INTRODUCTION: Pharmacokinetic parameters assessment is a critical aspect of drug discovery and development, yet challenges persist due to limited training data. Despite advancements in machine learning and in-silico predictions, scarcity of data hampers accurate prediction of drug candidates' pharmacokinetic properties. AREAS COVERED: The study highlights current developments in human pharmacokinetic prediction, talks about attempts to apply synthetic approaches for molecular design, and searches several databases, including Scopus, PubMed, Web of Science, and Google Scholar. The article stresses importance of rigorous analysis of machine learning model performance in assessing progress and explores molecular modeling (MM) techniques, descriptors, and mathematical approaches. Transitioning to clinical drug development, article highlights AI (Artificial Intelligence) based computer models optimizing trial design, patient selection, dosing strategies, and biomarker identification. In-silico models, including molecular interactomes and virtual patients, predict drug performance across diverse profiles, underlining the need to align model results with clinical studies for reliability. Specialized training for human specialists in navigating predictive models is deemed critical. Pharmacogenomics, integral to personalized medicine, utilizes predictive modeling to anticipate patient responses, contributing to more efficient healthcare system. Challenges in realizing potential of predictive modeling, including ethical considerations and data privacy concerns, are acknowledged. EXPERT OPINION: AI models are crucial in drug development, optimizing trials, patient selection, dosing, and biomarker identification and hold promise for streamlining clinical investigations.

ABSTRACT

Most women use medication during pregnancy. The disposition of drugs may be altered due to changes in pregnant women's bodies. This may call for pregnancy-adjusted doses for certain medications. However, in the face of scarce evidence, such doses are generally lacking, potentially contributing to an increased risk of treatment failure or toxicity in pregnant women and their unborn children. By integrating physiological and/or population data, pharmacokinetic models can be used to determine appropriate medication dosages among pregnant women and their unborn children, as well as other patient groups for which evidence-based doses may be lacking such as children, elderly or obese patients. In order to translate model predictions into clinically usable doses, a number of conditions must be met, including careful model validation, an assessment of evidence from pharmacokinetic modelling alongside available clinical studies by multidisciplinary experts, as well as transparent communication towards end-users on the considerations for determining appropriate medication doses.

ABSTRACT

BACKGROUND: Hospitals can leverage their position between the ultimate buyers and sellers of drugs to retain a substantial share of insurer pharmaceutical expenditures. METHODS: In this study, we used 2020-2021 national Blue Cross Blue Shield claims data regarding patients in the United States who had drug-infusion visits for oncologic conditions, inflammatory conditions, or blood-cell deficiency disorders. Markups of the reimbursement prices were measured in terms of amounts paid by Blue Cross Blue Shield plans to hospitals and physician practices relative to the amounts paid by these providers to drug manufacturers. Acquisition-price reductions in hospital payments to drug manufacturers were measured in terms of discounts under the federal 340B Drug Pricing Program. We estimated the percentage of Blue Cross Blue Shield drug spending that was received by drug manufacturers and the percentage retained by provider organizations. RESULTS: The study included 404,443 patients in the United States who had 4,727,189 drug-infusion visits. The median price markup (defined as the ratio of the reimbursement price to the acquisition price) for hospitals eligible for 340B discounts was 3.08 (interquartile range, 1.87 to 6.38). After adjustment for drug, patient, and geographic factors, price markups at hospitals eligible for 340B discounts were 6.59 times (95% confidence interval [CI], 6.02 to 7.16) as high as those in independent physician practices, and price markups at noneligible hospitals were 4.34 times (95% CI, 3.77 to 4.90) as high as those in physician practices. Hospitals eligible for 340B discounts retained 64.3% of insurer drug expenditures, whereas hospitals not eligible for 340B discounts retained 44.8% and independent physician practices retained 19.1%. CONCLUSIONS: This study showed that hospitals imposed large price markups and retained a substantial share of total insurer spending on physician-administered drugs for patients with private insurance. The effects were especially large for hospitals eligible for discounts under the federal 340B Drug Pricing Program on acquisition costs paid to manufacturers.

ABSTRACT

OBJECTIVE: To assess whether reporting the dosing frequency into the prescription module of the Institut Català de la Salut (ICS) primary care electronic clinical workstation improves the dosing frequency's adequacy of the prescriptions. DESIGN: Before and after study with non-equivalent control of prescriptions without any change in the dosing frequency. The study periods includes from September 1st, 2019 to February 29th, 2020. LOCATION: Primary care setting. PARTICIPANTS: Prescriptions issued by ICS General Practitioner, during the study period of those medicines which indications have a single appropriate dosing frequency or mostly appropriate, are included. INTERVENTION: Recommendation of the appropriate dosing frequency in the prescription module. MAIN MEASUREMENTS: Adequacy defined as the coincidence between the prescribed dosing frequency and the appropriate dosing frequency. RESULTS: After the intervention there was a 22.75% increase in prescriptions with adequate dosing frequency. The largest increase occurred in the medicines for the genitourinary system and sex hormones. In absolute terms, the group of anti infective for systemic use is the one that obtained more prescriptions with an adequate dosing frequency between the two periods. CONCLUSIONS: The intervention increased the dosing frequency's adequacy leading to improvements in the safety and effectiveness of the treatments. It is evident that the design and implementation of improvements in electronic prescription systems contributes to increasing the quality of the prescription.

ABSTRACT

Older adults are the main users of medicine and due to common multimorbidity they are often confronted with a complex medication management. This review article provides a brief overview on aspects of medication management, i.e., maintaining a stock of the required medicine, understanding and following the instructions for use, coping with the primary and secondary packaging, as well as the preparation prior to use. However, the main focus is on the drug intake itself and the review provides an overview of the current understanding of real life dosing conditions in older adults and geriatric patients. It elaborates the acceptability of dosage forms, in particular solid oral dosage forms as they represent the majority of dosage forms taken by this patient population. An improved understanding of the needs of older adults and geriatric patients, their acceptability of various dosage forms, and the circumstances under which they manage their medications will allow for the design of more patient-centric drug products.

ABSTRACT

Solid oral medications are preferred over intravenous or liquid formulations; however, difficulty swallowing solid medication remains a common barrier to adherence. Previous reviews have demonstrated limited evidence on interventions to improve solid medication swallowing abilities. PubMed, Medline (OVID), CINAHL, Scopus, and Web of Science databases were searched for interventions to improve the pediatric population's ability to swallow solid medications. We included studies in English published after the latest review, from January 2014 through April 2022, with pediatric patients not having comorbid conditions affecting swallowing ability. The authors independently reviewed each study's sampling strategy, study design, and the strength of outcome measures and assigned a numerical rating representing "poor," "fair," or "good" for each category. Individual ratings were averaged per category and a final quality rating score given based on the average of all 3 categories. Our search identified 581 unique records; 10 were included in the final review. Interventions varied and included behavioral therapies and novel products or medication formulations. Three received a "good" quality rating, 5 were "fair," and 2 were "poor." All studies showed their intervention(s) to be successful in improving a child's ability to swallow solid oral medications. Despite the availability of several different effective interventions, pediatric providers do not routinely address patients' difficulty with swallowing solid oral medications. Patients would benefit from implementation of a universal screening process followed by a guideline for appropriate patient-centered interventions; the opportunity exists to use this process as a national quality benchmark reflecting institutional commitment to high-value care.

ABSTRACT

Many drugs are used off-label in neonates which leads to large variation in prescribed drugs and dosages in neonatal intensive care units (NICUs). The NeoDose project aimed to develop best evidence dosing recommendations (DRs) for term and preterm neonates using a three-step approach: 1) drug selection, 2) establishing consensus-based DRs, and 3) establishing best evidence DRs. METHODS: The selection of drugs was based on frequency of prescribing, availability of a neonatal DR in the Dutch Pediatric Formulary, and the labeling status. Clinical need, pharmacological diversity, and Working Group Neonatal Pharmacology (WGNP) preferences were also taken into account, using a consensus-based approach. For the second step, we requested local dosing protocols from all ten Dutch NICUs and established consensus-based DRs within the WGNP, consisting of neonatologists, clinical pharmacologists, hospital pharmacists, and researchers. In the third step, the consensus-based DRs were compared with the available literature, using standardized PubMed searches. RESULTS: Fourteen drugs were selected for which the local dosing protocols were collected. These protocols differed mostly in total daily dose, dosing frequency, and/or route of administration. Strikingly, almost none of the dosing protocols of these 14 drugs distinguished between preterm and term neonates. The working group established consensus-based DRs, which after literature review needed modification in 56%, mainly in terms of a dose increase. Finally, we established 37 best evidence DRs, 22 for preterm and 15 for term neonates, representing 19 indications. CONCLUSION: This project showed the successful three-step approach for the development of DRs for term and preterm neonates.

ABSTRACT

BACKGROUND: Trials evaluating drug discontinuation (drug discontinuation trials, DDTs) show a broad methodological spectrum. There are several specific methodological aspects in drug discontinuation trials (e.g., determination of research question; configuration of intervention; definition of outcomes). To verify this specifies, we did a scoping review about the study designs of drug discontinuation trials. METHODS: A systematic literature search in Medline (PubMed), The Cochrane Library, EMBASE, CINAHL, Web of Science, and PsycINFO was performed. In a two-step selection process, we identified DDTs, which evaluate the discontinuation of one or more long-term medication as the investigated intervention, by two independent reviewers. Besides bibliographic data, we extracted several parameters to describe the used study design of the included DDTs: motivation for DDT, initially treatment aim of the discontinued medication, study design, methods of discontinuation, follow-up times, number of study participants, and outcome parameter. RESULTS: Out of 12,132 records, we included 581 DDTs. The most common motivation for doing a DDT were expected side effects (48.8%), the motivation of proving the efficacy of medication (21.6%), or doubts on the expected benefit of the used medication (13.8%). The majority of the discontinued medication was initially prescribed to improve the prognosis of a chronic disease (60.4%) or to relieve symptoms (31%). The study designs of the trials showed a broad methodological spectrum. The minority of the drug discontinuation trials were randomized controlled trials (34%). CONCLUSION: The results of this scoping review illustrates the need for an evidence-based methodological standard for planning and conducting drug discontinuation trials.

ABSTRACT

Abstract Solubility of pharmaceutical drugs in organic solvents is one of the important parameters to understand the equilibrium concentration of solute-solvent, which helps optimize and design crystallization conditions to obtain the desired product crystals. In the present study, Chlorzoxazone (CHZ) is used as a model pharmaceutical compound to investigate the equilibrium solubility, the influence of solvent and the operating conditions on the shape, and the size distribution. The solubility of CHZ is determined in organic solvents like Isopropanol, Ethanol, and 2-Ethoxyethylacetate, Ethylacetate and Ethyllactate using shake flask method from -5ºC to 60ºC. The solubility of CHZ in these solvents shows an increasing trend as the temperature increases in the following order: ethyllactate + water (0.5+0.5) < ethylacetate < isopropanol < ethanol < 2-ethoxyethylacetate < ethyllactate + water (0.75+0.25). The solvents, isopropanol, ethanol, and ethyl lactate, produce needle-shaped crystals, while 2-ethoxyethylacetate and ethyl acetate tend to produce plate shaped crystals. CHZ crystals obtained from 2-ethoxyethylacetate tend to have plate shaped crystals with a lower aspect ratio and are selected for batch cooling crystallization experiments performed at different cooling rates, and agitation. It is found that the agitation at 300 rpm and the cooling rate 0.2ºC/min produce more uniform crystal size distribution

ABSTRACT

Abstract Propolis is a resinous hive product collected by bees from the buds or other parts of plants. It is known for having various biological properties, including antifungal activity. Among the substances present in propolis, flavonoids and phenolic acids and their esters are responsible for its antifungal properties. This means that propolis is ideal for use as an antifungal agent in alternative medicine to treat a number of both topical and systemic infections caused by Candida species and other yeast-like fungi, dermatophyte and nondermatophyte moulds, without the serious side effects typical of synthetic treatment. It is also active against strains of fungi that are resistant to polyenes and azoles, the classes of drugs most commonly used to treat fungal infections. In this article, we review current knowledge about the activity of propolis from different parts of the world and its components in vitro and in vivo against pathogenic fungi isolated from human infections. The article also indicates the possible mechanism of antifungal activity of propolis and its components.

ABSTRACT

Abstract The form of drug administration affects the success of treatment, since it can influence adherence of the patient to the therapy. The use of orodispersible films has emerged as a way to overcome some drawbacks of conventional methods of drug delivery, especially for patients experiencing difficulty in swallowing. These films are prepared using a matrix that incorporates the drug and contains other substances that confer the properties of the system. The present work describes the use of thermoplastic starch as a carrier for the model drug diclofenac, including film preparation and testing of its orodispersible potential. Preparation of the film employed a microwave oven to gelatinize and plasticize corn starch, with incorporation of the model drug, followed by solvent-casting. The samples were characterized using mechanical tests, analyses of water uptake and water content, and Fourier transform infrared spectroscopy. The results indicated that the film presented promising properties as an alternative system for oral drug administration, with good incorporation and distribution of the drug in the matrix. The material displayed satisfactory mechanical properties, which are crucial for this type of material, due to the need for oral administration and handling before use.

ABSTRACT

Abstract This work analyzed the pharmacotherapeutic problems identified by the clinical pharmacist in an intensive care unit (ICU) and the acceptance of pharmaceutical interventions in solving these problems. This is a descriptive cross-sectional retrospective study, carried out in the adult ICU of a public hospital. All patients hospitalized during the study period had their pharmacotherapy monitored and those whose stay at the ICU lasted less than 24 hours were excluded. The pharmacotherapeutic problems were classified according to type, cause, acceptability/implementation, mode of intervention, outcome and related pharmacotherapeutic group. 302 patients were followed up and 350 pharmacotherapeutic problems were identified. Most of them were classified as unnecessary drug-treatment (n=186; 53.1%). The most frequent causes were excessive drug administration (n=181; 97.3%), and antimicrobials was the main group of drugs associated to that type of problem. 350 pharmaceutical interventions were performed, highlighting "prescriber informed only" (n=178; 50.9%), with an average acceptability of 90.7%, with those carried out on site being more effective (93.4%). The number of pharmacotherapeutic problems that were totally solved was 282 (80.6%). Clinical pharmacy activities in the ICU identified, prevented and corrected pharmacotherapeutic problems, contributing to the optimization of pharmacotherapy in aspects related to the need, efficacy and safety of treatments.

ABSTRACT

Abstract For asthma treatment in children, caregivers need good knowledge and attitudes regarding the disease and its treatment. This study aimed to determine the impact of cultural factors, the level of health education provided to patients and their families, as well as the impact of stigmatization on the treatment awareness of children with asthma in southern Jordan. A validated questionnaire was used to collect data from a sample of ninety-seven caregivers selected from three hospitals in southern Jordan. Open ended questions were answered after demonstrating the inhaler technique in and evaluated according to the instructions of the National Asthma Education and Prevention Program (NAEPP, 2013). The result revealed moderate knowledge of asthma with a mean score of (22.36/32), as well as moderate knowledge of asthma treatment (24.26/40). A high mean was found for the impact of cultural and environmental factors (22.93/28), whereas low impact was found for stigma with a mean value of (4.73/12). Therefore, to improve future asthma management, additional efforts are required to educate caregivers and improve their asthma awareness and rectify any falsehoods regarding asthma medications by health care providers.
