ABSTRACT

The aim of this study was to investigate the acute effects of atracurium besylate on cellular damage in corneal endothelium of chickens. Twenty healthy chicken eyes were assigned to the following groups: Group 1 (G1), experimental group (n=10); and Group 2 (G2), control (n=10). Excised corneoscleral buttons were immediately placed on glass microscopy slides with endothelial region faced up. Corneal endothelium of eyes in G1 were covered with AB (0.2mL, 10mg/mL) for 3 min and then rinsed with balanced salt solution (BSS), while the corneal endothelium of eyes in G2 were covered with BBS for 3 min. Corneas from both groups were stained with alizarin red/trypan blue and visualized by light microscopy. Ten random photographs were taken from each cornea. The area of cellular damage was measured by software in all samples and cell loss of each group was averaged and compared. Endothelial area of denudation and Descemet's membrane exposure were higher in G1 than G2. In conclusion, atracurium besylate induced an acute damage on corneal endothelium of chickens.(AU)'


Objetivou-se avaliar os efeitos agudos do besilato de atracúrio sobre o endotélio corneano de galinhas. Vinte olhos saudáveis de galinhas foram aleatoriamente separados em dois grupos com 10 olhos cada, sendo G1 o grupo controle e G2 o grupo tratamento. Imediatamente após a excisão dos botões corneoesclerais estes foram colocados em lâminas de microscopia de vidro com o lado endotelial voltado para cima. No Grupo 1, o endotélio corneano foi recoberto com 0,2ml de besilato de atracúrio (10mg/ml) durante 3 minutos e depois lavado com solução salina balanceada. No Grupo 2, o endotélio corneano foi recoberto apenas com solução salina balanceada durante 3 min. As córneas de ambos os grupos foram coradas com vermelho de alizarina e azul de tripano e visualizadas com microscópio óptico. Foram obtidas dez fotografias aleatórias de cada amostra. As imagens foram analisadas e com auxílio de um software as áreas com ausência de células endoteliais calculadas. A perda celular endotelial foi significativamente maior no grupo tratamento comparativamente ao grupo controle. Com base nos resultados apresentados foi possível concluir que o besilato de atracúrio induziu dano agudo nas células do endotélio da córnea de galinhas.(AU)

ABSTRACT

El presente trabajo de investigación tiene el objetivo de comparar la farmacodinámia tanto del Besilato de Atracurio Tracrium® (molécula original), con la del Besilato de Atracurio (Genérico), a través del monitoreo de la función neuromuscular con un estimulador neuromuscular periférico y de esta forma recoger la información necesaria para facilitar la toma de decisión en la elección del producto farmacéutico que reúna las mejores condiciones tanto de eficacia farmacológica como económica. Se realizó un estudio prospectivo en 35 pacientes ASA I, distribuidos aleatoriamente en dos grupos Grupo A (n=18) en los que se administró la droga genérica y el grupo B (n=17) en los que se administró la molécula original, con posterior monitoreo de la función neuromuscular con un neuroestimulador periférico. Concluyéndose que tanto el Besilato de Atracurio genérico como la molécula original Tracrium® tienen características farmacodinámicas muy similares y ambas son eficaces para producir un bloqueo neuromuscular adecuado, dándonos la posibilidad de poder decidir la mejor oferta económica sin el temor de adquirir una droga que no sea eficaz.


The present investigation have the objective to compare the pharmacodynamics characteristic of Besilatio of Atracurium (original molecule) and the Besilatio of Atracurium (Generic), trough the monitoring of the neuromuscular function with a neuromuscular peripheal stimulative; this will provide the enough information to make the rigth decision in the election o the farmaceutical product that gathers the best conditions among the pharmaceutical efectiveness and the economic part We made a prospective study with 35 patients ASA I, distributed in two groups: Group A (n=18), those to whom it was administraded the Generic drug, and Group B (n=17), those whom it was administraded the Original Molecule, with a later check through neuromuscular peripheal stimulous. We conduyed than the Besilatio of Atracurium like the original molecule have the same pharmacodynamics characteristic to produce an appropiate neuromuscular blockade, giving us the choice to choose the best economic ofert, without the fear of adquiring a drug that is not efective.
