Abstract

The aim of this study was to prepare and evaluate tablets containing liquid choline alphoscerate, which is capable of being formulated as a solid dosage form by the adsorption of magnesium aluminum silicate. The tablets were prepared with various absorbent to choine alphoscerate ratios. The physical properties and the dissolution rate were investigated. Considering the tabletting and dissolution rate, the formula scontaining 50-75% absorbent were adequate in the tested formulations. The 62.5% absorbent formula showed superior results with the tests of hardness, friability, disintegration time, and the ratio of dissolution area under the curve. Overall, magnesium aluminum silicate can be an alternative additive to a liquid drug.

본 연구에서는 액상 형태인 콜린알포세레이트를 알루미늄마그네슘규산화합물에 흡착시켜 고형의 제형화가 가능한 콜린알포세레이트를 함유하는 정제의 제조하고 평가하였다. 정제는 콜린알포세레이트 대비 흡착제의 비율을 달리하여 제조하고, 물리적 특성 및 용출률을 조사하였다. 정제의 타정성과 용출률을 고려할 때 흡착제는 주성분 대비 50~75%가 적절하였다. 주성분 대비 62.5%의 흡착제를 사용한 제제에서 정제의 경도, 붕해, 마손도 시험, 용출곡선하면적 비율 결과가 가장 우수하였다. 알루미늄마스네슘규산화합물은 액상 약물의 고형화 설계 시 좋은 소재가 될 수 있을 것이다.
