OCULAR IMPLANT MADE BY A DOUBLE EXTRUSION PROCES |
摘要 |
The invention provides biodegradable implants sized for implantation in an ocular region and methods for treating medical conditions of the eye. The implants are formed from a mixture of hydrophilic end and hydrophobic end PLGA, and deliver active agents into an ocular region without a high burst release. |

1. A bioerodible implant for treating an ocular condition comprising particles of an active agent dispersed within a biodegradable polymer matrix, wherein
at least 75% of the particles of the active agent have a diameter of less than 20 μm, the biodegradable polymer comprises poly(lactic-co-glycolic)acid (PLGA) copolymer, the ratio of lactic to glycolic acid monomers in the PLGA copolymer is 50/50 weight percentage, and the bioerodible implant is prepared by milling the biodegradable polymer and subjecting the active agent and the biodegradable polymer to a double extrusion process. |
