ABSTRACT
Ferric hexacyanoferrate, Fe4 [Fe(CN)6]3 · xH2O, known as Prussian blue (PB), has proven its effectiveness as an antidote in cases of accidental poisoning or poisoning caused by radioactive materials such as cesium (Cs) and thallium (Tl); which due to their solubility in water, when absorbed by the human body, cause serious damage to vital organs. The local development of a drug with PB as an active ingredient arises as a response to the civil and military needs established within the Ministry's pharmacy request for national defense. This fact contemplates the circumstances related to public health protection in the nuclear, radiological, biological and chemical (NRBQ) of the emergency institutions in health and national security. In this paper and by using various analytical techniques, the characterization of the locally synthesized PB with pharmaceutical quality has been described, as a first step to predict its behavior in the preparation of a drug that contains it as an active ingredient. The research findings demonstrate that locally synthesized PB is suitable for use in oral dosage forms, enabling the local development of drug formulations incorporating PB, thus being able to potentially become a main resource in the treatment of Cs and Tl poisoning in any accidental or intended of the population. This development opens up the possibility of creating drug formulations that incorporate PB at a local level, making it a potentially significant resource in the treatment of Cs and Tl poisoning. The ability to locally produce and utilize PB in oral dosage forms could be crucial in addressing cases of accidental or intentional exposure within the population. This advancement not only contributes to the scientific understanding of PB but also holds promising implications for practical applications in public health and emergency situations.
ABSTRACT
El objetivo de este trabajo fue estudiar la influencia de la divisibilidad en comprimidos de prednisona 30 mg. La división de comprimidos se utiliza a menudo en la práctica farmacéutica para ajustar las dosis administradas. La prednisona es un corticoesteroide (glucocorticoide) utilizado en el tratamiento de sustitución en la insuficiencia adrenal incluyendo entre otras la enfermedad de Addison. Como medicamento de referencia se utilizó Dacortin 30 mg, el cual se comparó con dos medicamentos genéricos. Se estudiaron diferentes características farmacotécnicas para evaluar la calidad de los comprimidos estudiados, tales como la disgregación y la resistencia a la rotura. Atendiendo al estudio de fraccionamiento de comprimidos, se determinó la diferencia sobre el peso teórico esperado (pérdida de masa media tras el fraccionamiento de cada marca comercial). La liberación del principio activo se estudió mediante el ensayo de velocidad de disolución en fracciones de comprimidos. Los resultados de las tres presentaciones comerciales fueron estudiados y analizados estadísticamente con un nivel de confianza de un 95 %
The objective of this work was to study the influence of the division in prednisone tablets 30 mg. The division of tablets is often used in pharmaceutical practice to adjust the administered doses. Prednisone is a corticosteroid (glucocorticoid) used in the substitution treatment in adrenal insufficiency including, among others, Addison's disease. As a reference drug, Dacortin 30 mg was used, and compared with two generic drugs. Different pharmacotechnic characteristics were studied to evaluate the quality of the tablets studied, such as disintegration, and the resistance to crushing. Based on the study of tablet fractionation, the difference over the expected theoretical weight was determined (loss of average mass after the fractionation of each trademark). The release of the active substance was carried out with dissolution rate study in fractions of tablets. The results of the three commercial formulations were studied and statistically analyzed with a confidence level of 95 %

Las formas de dosificación bucodispersables son productos farmacéuticos que se disgregan y disuelven rápidamente en la saliva cuando se colocan en la boca. Hay distintos tipos de formulaciones y procesos de fabricación que pueden emplearse para su elaboración. En este trabajo, se estudia las diferencias entre los genéricos bucodispersables con 10 mg de olanzapina comercialmente disponibles en España y Zyprexa Velotab reconocido como innovación galénica. Se han analizado distintos aspectos, tales como forma y tamaño, formulación cualitativa, tiempo de disgregación in vitro en saliva artificial y material de acondicionamiento. Entre todos los productos analizados, Zyprexa Velotab fue el que tuvo una ultrarrápida disgregación en 3 segundos y el menor residuo de dispersión (AU)
Orally dispersable dosage forms are pharmaceutical products that disintegrate and dissolve rapidly in saliva when placed in the mouth. There are several types of formulations and manufacturing technologies, which may be used to produce orodispersibles. This work investigates different generic 10 mg olanzapine orodispersible products commercially available in Spain and the innovative Zyprexa Velotab manufactured by Eli Lilly & Co. Several aspects such as the shape and size, qualitative formulation, in vitro disintegration time in artificial saliva and packaging are analyzed. Among all the products tested Zyprexa Velotab showed an ultra fast disintegration in 3 seconds and the lowest dispersión (AU)
