Estudios farmacocinéticos y biofarmacéuticos del acamprosato en la rata.

El acamprosato o bis-acetilhomoaurinato cálcico es un fármaco que se emplea en la terapia de mantenimiento de la abstinencia en pacientes dependientes del alcohol. Sin embargo, uno de los problemas más importantes en su manejo clínico deriva de su reducida biodisponibilidad oral en magnitud (BD), que se sitúa en torno a un 11% en humanos. Por ello, mediante el empleo de diversos y sencillos diseños experimentales se ha abordado el estudio de dos de los procesos menos conocidos de su farmacocinética, la absorción y la eliminación. El estudio de la linealidad farmacocinética del acamprosato se ha realizado tras la administración intravenosa rápida de 2.8, 11 ó 22 mg del fármaco, así como tras…

Different brain oxidative and neuroinflammation status in rats during prolonged abstinence depending on their ethanol relapse-like drinking behavior: Effects of ethanol reintroduction

Rationale: Accumulating evidence suggests that chronic alcohol consumption is associated with excessive oxidative damage and neuroinflammatory processes and these events have been associated to early alcohol withdrawal. In the present research we wonder if brain oxidative stress and neuroinflammation remains altered during prolonged withdrawal situations and whether these alterations can be correlated with relapse behavior in alcohol consumption. The effects of alcohol reintroduction were also evaluated Methods: We have used a model based on the alcohol deprivation effect (ADE) within a cohort of wild-type male Wistar rats. Two subpopulations were identified according to the alcohol relapse…
