Abstract:
【Objective】To prepare rapamycin（RAPA）sustained-release film and to evaluate its dissolution.【Methods】RAPA sustained- release film was created by using polymer polyactioglyconic acid （PLGA），copolymer of polyactic acid（PLA）and polyglycolic acid（PGA）. Drug content of the sustained-release film was determined using specificity test，recovery，relative standard deviation（RSD）and stability test. Then，the dissolution of the sustained- release film was analyzed.【Results】The concentration of RAPA had a linear relationship with peak area，which ranged between 0.408 μg/mL and 40.8 μg/mL through the standard curve. The specificity test of the drug content determination indicated the excipient of the film and the solution with 0.3% sodium dodecyl sulfate（SDS）did not affect in determining the RAPA content. The recovery and RSD were excellent through drug content determination in blank films，which had three different levels of RAPA concentrations. The mean RAPA content of the sustained-release films was（112.6±10.1）μg（RSD 8.99%）through the drug content determination of the films，and the stability of RAPA with 0.3% SDS was good within 15 days. In addition，dissolution test of the sustained- release film indicated that the amount of drug release reached a high level and sustained up to 15 days.【Conclusion】 The RAPA sustained-release film with certain behavioral characteristic parameters had a stable drug content and favorable sustained-release property，and it may have certain application potential in anti-proliferation after glaucoma filtering surgery.
