Abstract
Patente de Invenção: <B>BASE EFERVESCENTE"<D>. A base efervescente para a preparação de comprimidos efervescentes e grânulos efervescentes consiste em pelo menos um componente de desenvolvimento de gás, cujo primeiro é formado por uma mistura de (predominantemente) tartarato de monossódio e (possivelmente) tartarato de dissódio, e opcionalmente ácido tartárico. A base efervescente é preparada por misturação de ácido tartárico com bicarbonato de sódio e carbonato de sódio contendo água de cristalização e reação lenta da mistura em uma temperatura que aumenta para cerca de 50°C, depois da qual mais carbonato de sódio contendo água de cristalização é misturado e é deixado reagir até uma temperatura de cerca de 60°C, e secagem é então realizada, de preferência em vácuo, a mistura é misturada com mais, agora carbonato de sódio anidro e o produto é opcionalmente prensado para dar comprimidos. A base pode adicionalmente compreender uma substância farmaceuticamente ativa sensível a álcali ou sensível a ácido.
