Abstract

fetched live from OpenAlex

A acetazolamida (ACZ) um potente inibidor da anidrase carbnica, utilizado no tratamento de epilepsia, edema cardaco, edema induzido por medicamentos e na aclimatao de alpinistas e indivduos susceptveis ao mal da montanha. Este frmaco pertence classe IV do Sistema de Classificao Biofarmacutica (SCB) portanto possui baixa solubilidade e baixa permeabilidade. Existem diversas abordagens promissoras para melhorar as condies desfavorveis da solubilidade de frmacos classe II e IV. Entre estas tcnicas temos a micronizao, uma das mais conhecidas e utilizadas na indstria farmacutica, cujo principal objetivo o aumento da solubilidade e da velocidade de dissoluo como decorrncia da reduo do tamanho de partcula do frmaco. Outra abordagem que visa esta melhora a formao de complexos binrios e ternrios a base de ciclodextrinas. Estudos de desenvolvimento de comprimidos orodispersveis (CODs), forma farmacutica slida de rpida desintegrao e dissoluo vem ganhando muito interesse pelos pesquisadores devido a que permitem um aumento significativo da biodisponibilidade do frmaco e aceitao do paciente. Nesse sentido, o presente trabalho teve como objetivo a preparao e a caracterizao fsico-qumica de micronizados de ACZ para posterior desenvolvimento de comprimido de liberao imediata. Os resultados demostraram que o processo de micronizao aumentou de forma significativa a solubilidade e velocidade de dissoluo da ACZ em tampo fosfato pH 6,8. Adicionalmente a produo de comprimidos utilizando estes

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
