Abstract:
Objective To study the physical-chemical parameters of antiviral drug GZ 914 and provide data for the preparation design .Methods The appearance , crystal structure and solubility of GZ 914 were investigated .An HPLC method was established to determine the content of GZ 914 in vitro before oil/water partition coefficient and solubility in different pH experiments were calculated .Results GZ914 was a straw yellow powder with a crystalline structure , low water-solubility and good lipotropy .The HPLC method had a good linear relationship within the range of 12-60 μg/ml (r=0.9998).The oil/water partition coefficient of GZ914 was 1.9.Conclusion This analytical method is accurate and reliable.The oil/water partition coefficient indicates that the drug could be formulated as an oral solid preparation.
