چکیده
Small molecule chemotherapeutics often have undesired physiochemical and pharmacological properties, such as low solubility, severe side effect and narrow therapeutic index. To address these challenges, polymeric nanomedicine drug delivery technology has been routinely employed, in particular with the use of biodegradable and biocompatible polyesters, such as poly(lactide) (PLA) and poly(lactide-co-glycolide) (PLGA). Here we review the development and use of PLA and PLGA for the delivery of chemotherapeutic agents in the forms of polymer-drug conjugates and nanoconjugates.

Encapsulation of Naja –Naja Oxiana Snake venom into Poly (lactide-co-glycolide) microspheres
One small-scale double emulsion technique for incorporation of Naja- Naja oxiana venom into Poly (lactide-co-glycolide) (PLGA) microspheres were developed and optimized. The effects of high speed homogenization on the double emulsion stability, microsphere size, entrapment efficiency and In vitro release of venom were studied. A stable double emulsion was verified by homogenization method. Slow...
متن کاملThermal properties and morphology changes in degradation process of poly(L-lactide-co-glycolide) matrices with risperidone.
Determining thermal properties and morphology seems to be useful in the analysis of release and degradation processes form polymeric materials. Risperidone is available in the formulation of a long-acting injection based on poly(D,L-lactide-co-glycolide). Currently, alternative solutions are also offered, i.e., nano- and microparticles or implants, including copolymers of lactide and glycolide....

Four monomethoxy poly(ethylene glycol)-poly(L-lactide-co-glycolide)(2) (mPEG-P( LA-co-GA)(2)) copolymers were synthesized by ring-opening polymerization of L-lactide and glycolide with double hydroxyl functionalized mPEG (mPEG-(OH)(2)) as macroinitiator and stannous octoate as catalyst. The copolymers self-assembled into nanoscale micellar/vesicular aggregations in phosphate buffer at pH 7.4. D...
