Powder dissolution test under sink conditions showed improved dissolution profiles of drug-TA co-amorphous formulations compared to the corresponding crystalline drugs and physical mixtures. Tannic acid also showed a superior stabilizing effect. CBZ-TA co-amorphous system was physically stable at dry conditions (up to 6 months at 40 °C), under 60% relative humidity (up to one month at 20 °C), and in solution (after 48 h of solubility measurements), as revealed by PXRD examination of the remaining solid after solubility me
