Por ello, es necesario analizar y establecer la relación riesgo/beneficio de políticas relacionadas con la salud mental, caso de la legalización del consumo de cannabis recreativo en adultos. El cannabis es la droga “ilícita” de mayor consumo en los países occidentales, en esencia por incrementar la sociabilidad y la euforia. En la última década, varios países han promulgado normas orientadas a legalizar la comercialización de cannabis recreativo en adultos. En este sentido, existe controversia del efecto de este tipo de iniciativas, en el porcentaje de personas que consumen esta sustancia y en la salud de los mismos. Sin embargo, se podría esperar que este tipo de iniciativas favorezca un aumento en el porcentaje de personas que consumen esta sustancia. El aumento del consumo de marihuana puede favorecer una mayor prevalencia de problemas de salud mental, incluyendo psicosis y esquizofrenia. Se acepta la existencia de una asociación entre consumo de cannabis y psicosis (incluyendo esquizofrenia). En este marco, reconociendo los beneficios de las políticas de legalización del consumo de cannabis recreativo en adultos, orientadas a superar el enfoque prohibicionista y a buscar la reducción del daño, es conveniente evaluar y definir el efecto de las mismas. Además, estas iniciativas se deben acompañar de programas informativos y educativos, orientados a sintetizar los riesgos del consumo, incluyendo, la dependencia y problemas de salud mentales.","PeriodicalId":54103,"journal":{"name":"Ars Pharmaceutica","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136061200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Aquasomal drug delivery system: A special emphasis on the formulation techniques and applications","authors":"Prakash Rajak, Rofiqul Islam, Arka Karmakar, Biman Bhuyan","doi":"10.30827/ars.v64i4.28264","DOIUrl":"https://doi.org/10.30827/ars.v64i4.28264","url":null,"abstract":"Introduction: Aquasome is a self-assembled nanoparticulate carrier system with three layers. The system is made up of a polyhydroxy oligomer-coated inner nanocrystalline solid core. Adsorbed on the coated layer are drug molecules or biochemically active compounds. Self-assembly in this sense refers to the independent formation of molecules into organised, long-lasting, and non-covalently bonded patterns.This paper gives an overview of aquasome formation, covering structural properties, formulation methodologies, and the benefits and drawbacks of this novel drug delivery technology. The article primarily addresses the formulation processes used to create self-assembled nanostructures and their various possible applications. Method: Several online databases, including Science Direct, Medline, Web of Science, Google Scholar and Scopus, were used in the literature search. The datasets were searched for entries of studies up to July, 2023. The review paper especially addresses many elements of aquasome formation by various researchers employing methods/modified techniques such as co-precipitation, self-precipitation, sputtering, and and so forth. It also illustrates a variety of fields of therapy in which aquasome has been recognised to have a major influence, such as oxygen and extract carrier. Results: The solid core is responsible for providing structural stability, while the oligomeric coating is crucial for safeguarding against dehydration and stabilising the bioactive molecules. This biodegradable drug delivery vehicle at the nanoscale level exhibits a tendency to accumulate in the liver and muscles. The non-modification of drug adsorption onto the aquasome surface facilitates prompt pharmacological response by allowing unobstructed receptor recognition at the action site. Conclusions: Aquasome, a three-layered self-assembled molecule, is a simple yet new drug delivery system with promising carrier potentials to increase the solubility and bioavailability of poorly soluble drugs. Despite a host of challenges, such as time consumption, sophisticated processes, safety, and expensive research costs, aquasome may emerge as an alternative vesicular carrier in the future.","PeriodicalId":54103,"journal":{"name":"Ars Pharmaceutica","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136061206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Su similitud a esteroides endógenos de mamíferos les otorga actividad biológica sobre el tejido muscular esquelético. Sin embargo, su mecanismo de acción está por definirse en su totalidad. Método: Se realizó una revisión narrativa utilizando la evidencia científica más relevante. Se consultaron de las bases de datos Medline, Google Scholar, Scielo y Wiley, incluyéndose y excluyéndose trabajos acordes a los criterios del autor. Resultados: La actividad de los ecdiesteroides, principalmente de la Ecdisterona (Ec), podría deberse a la interacción con Mas, receptor acoplado a proteína-G transmembrana (GPCR), y la posterior activación del receptor de estrógenos β (ER β) no nuclear. Dicho mecanismo de acción induce la activación de la ruta alternativa del Sistema Renina-Angiotensina-Aldosterona (RAA) aboliendo los mecanismos de degradación muscular y, mediante la activación indirecta de Erβ, se suprime la expresión del gen de la miostatina. Esta actividad biológica pudiera conferir a los ecdiesteroides propiedades farmacológicas óptimas para impedir la degradación proteico-muscular, tales como la regeneración y reparación del tejido. Conclusiones: Ec ha demostrado poseer propiedades farmacológicas interesantes para el abordaje alternativo de patologías musculodegenerativas por sus efectos anticatabólicos. Aunque prosigue la investigación para su implementación en la clínica, esta siendo utilizada en la industria deportiva y en ensayos para el tratamiento de diferentes patologías.","PeriodicalId":54103,"journal":{"name":"Ars Pharmaceutica","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136061202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Solubility data and solubility parameters of barnidipine in different pure solvents","authors":"Mª Ángeles Peña-Fernández, Gaia Spanò, Norma Sofía Torres Pabón, Fleming Martínez","doi":"10.30827/ars.v64i4.27728","DOIUrl":"https://doi.org/10.30827/ars.v64i4.27728","url":null,"abstract":"Introduction: Solubility studies and obtaining physicochemical data on drugs in pure solvents belonging to different chemical classes are key to developing new drug formulations. In this work, Hansen partial solubility parameters (HSP) were calculated to assess the miscibility and intermolecular interactions of barnidipine in seventeen pure solvents. The comparison of the results obtained with the theoretical values ​​calculated according to the structure of barnidipine, were valuable to analyse the influence of the solute-solute, solute-solvent relationships of the additive contribution groups, on the chemical and physical properties of this molecule with the solvents of different polarity tested, to provide relevant information highly useful in the pharmaceutical industry. Method: Equilibrium barnidipine solubilities in mono-solvents was determined using the classical shake-flask method, followed by UV-spectrophotometric analysis at 298.15 K. The partial solubility parameters were calculated by applying theoretical group contribution methods, proposed by Hoftyzer-Van Krevelen and Fedors. The KAT-LSER model was used to investigate the effect of solvent based on the concept of linear solvation energy relationships. The mole fraction was obtained from the densities of the solutions. Solid-phase analyses were made by calorimetry differential scanning. Results: The modification introduced in the extended Hansen method, that is, the use of lnX2 as the dependent variable, provided excellent results. The highest solubility values have been found in polar solvents. It is observed that solvent-solvent and solute-solvent intermolecular interactions through hydrogen bonds and van der Waals forces, significantly influence drug solubility. Conclusions: The affinity between barnidipine and each one of the selected solvent was evaluated by using HSP. Results showed that HSP could be well used to analyse drug solubility in particular solvents. Barnidipine is easier to dissolve in solvents with shorter carbon chains and higher polarity.","PeriodicalId":54103,"journal":{"name":"Ars Pharmaceutica","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136060068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pharmacy practice has been defined as “the scientific discipline that studies the different aspects of the practice of pharmacy and its impact on health care systems, medicine use, and patient care”. Thus, pharmacy practice studies embrace both clinical pharmacy and social pharmacy elements. Like any other scientific discipline, clinical and social pharmacy practice disseminates research findings using scientific journals. Clinical pharmacy and social pharmacy journal editors have a role in promoting the discipline by enhancing the quality of the articles published. As has occurred in other health care areas (i.e., medicine and nursing), a group of clinical and social pharmacy practice journal editors gathered in Granada, Spain to discuss how journals could contribute to strengthening pharmacy practice as a discipline. The result of that meeting was compiled in these Granada Statements, which comprise 18 recommendations gathered into six topics: the appropriate use of terminology, impactful abstracts, the required peer reviews, journal scattering, more effective and wiser use of journal and article performance metrics, and authors’ selection of the most appropriate pharmacy practice journal to submit their work.","PeriodicalId":54103,"journal":{"name":"Ars Pharmaceutica","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135135661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
