9-OH-risperidone controlled release composition

This describes an implantable composition designed to release a drug slowly and consistently into the body. It's made from a biodegradable polymer, primarily polylactic acid, and contains either risperidone or 9-OH-risperidone. The drug makes up 10-20% of the implant's mass, ensuring a controlled release over time.

Why it matters: No specific technological shift is evident from the claims or classification that would make this particular drug-polymer combination uniquely viable now compared to 2018. The challenges of specialized manufacturing and regulatory approval for medical implants likely remain.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedPolymer extrusion, drug formulation, regulatory compliance
