Aim To study the most stable pH value of endomorphin-1 solution and to estimate the shelf-life of EM-1 solution. Methods The content of EM-1 in its solution was determined by HPLC, and stability was studied by accelerated tests. Results The most stable pH value of EM-1 solution was observed. By the accelerated tests we obtained the Arrhenius relationship and the pharmacokinetic parameters. Conclusion The most stable pH value of EM-1 solution is 4.5 -4.8. The t1/2(25℃) is 45 d.
