Summary

Most analgesics require multiple oral administrations per day which frequently leads to poor compliance and often results in insufficient control over pharmacokinetic profiles. While sustained release injectable formulations offer improved compliance, they typically result in drug ‘burst’, followed by imprecise pharmacokinetics resulting in lack of tight control over the concentration of these drugs in the blood. Here, we explore the possibility of developing a safer, more effective extended pain reliever using Orbis Bioscience’s controlled release technology to reformulate a generic NSAID into a long-lasting injectable depot.
