Methods The content of EM-1 in its solution was determinedby HPLC, and stability was studied by accelerated tests. Results The most stable pH value of EM-1solution was observed. By the accelerated tests we obtained the Arrhe-nius relationship and thepharmacokinetic parameters. Conclusion The most stable pH value of EM-1 solution is 4.5 -4.8. Thet_(1/2)(25℃) is 45 d.展开更多
