Chlortetracycline hydrochloride (CTC) has been reported as having low aqueous solubility, leading to a limitation in its administration in treatments. This study demonstrated a strategy to enhance the supersaturated solubility of CTC by amorphous solid dispersion (SD). CTC-SDs were prepared with hydrophilic polymers, polyvinylpyrrolidone (PVP) and copovidone using various preparation methods: water bath evaporation, speed vacuum evaporation, and spray drying. Physicochemical properties and...
