  • Extended release bioabsorbable subcutaneous medicinal dosage delivery implant system
    Patent number: 11197819
    Abstract: An extended-release bio absorbable subcutaneous medicinal dosage delivery implant system includes an implant fabricated from a highly homogeneously mixed composition including a medicinal agent in combination with release controlling polymers which include poly (DL-lactide) and polycaprolactone. In one implementation for treating an opioid disease, the formulation composition includes naltrexone at 40 weight percent, poly (DL-lactide) in the range between 36 and 46.4 weight percent, and polycaprolactone in the range between 24 and 11.6 weight percent. In addition, in order to provide anti-biofouling quality and prevent foreign body adsorption/interaction with the material of the implant, polyethylene glycol is added in a preferred content of 2.0%. The manufacturing process includes hot melt extrusion and a mini jet based implant formation stage with the optimized process space were the temperature of the process ranges from 170° C.-180° C.
