PCL drug sustained-release carrier
Problem Phenomenon
PCL drug sustained-release carrier release rate and degradation matching, regulation difficulty.
Cause Analysis
PCL degradation rate and drug release; crystallinity influence; molecular weight; drug loading; release mechanism.；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Degradation rate regulation; ②Crystallinity management; ③Drug loading process; ④Release testing.；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability；Change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
Rate matching of PCL drug sustained release is the core; multi-factor regulation; tests verify the release curve.；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
