Sustained release and controlled release
SpletIn this work, we present the development of a novel chest tube that can deliver a sustained release of high concentrations of the local anesthetic bupivacaine. The drug is loaded into the tube by filling the pores of a sintered plastic tube with a drug loaded, controlled release polymer. As the drug is loaded within the tube wall the overall ...

In fact, many countries have already banned certain single-use plastics.
SpletControlled release or time release usually refers to the ability to engineer the rate of dissolution or release of the active ingredient so as to maximise its half-life within the body, but note that this is also a function of the rate of removal e.g., by the kidneys. SpletTo develop a sustained controlled release system, PS/hpGHA NPs were prepared using an LbL technique. Briefly, the PLGA-SA was first made by nanoprecipitation. PLGA and SA were dissolved into the DMSO/acetone mixture at 50°C and stirred for 1 hour. Then, 0.3% PVA solution (100 mL/h) was injected to control the particle size.
