| Abstract: | Objective To establish a method for determination of the entrapment efficiency of Nimodipine (NIM) nanoliposomes.Method The entrapment efficiency of NIM liposomes is determined by reverse dialysis method with HPLC for analyzing the amount of (NIM).Result The equilibrium time was 6 h. the average entrapment efficiency of NIM nanoliposomes was 85.69%±3.13%. The leaking percentage in 10 h was neglectable after reconstitution.Conclusion Reverse dialysis method was convenient and accurate. It was suitable for determining the entrapment efficiency of nanoliposomes of hydrophobic drugs such as nimodipine. |
