Many pharmaceuticals create drugs out of a uniform batch of chemically-tailored molecules that are aggregated into pills with a binder, or dissolved in saline. Currently, more innovative methods of drug delivery are being used. These designer drugs are composed of exotic bio-engineered compounds blended precisely together in various combinations, such as time-released, enteric resistant, or active and pro-drug mixes. A variety of these patented manufacturing and drug delivery methods are highlighted in our Mechanism of Action animations. From compounds assembling into microspheres, filtration through nanoscopic grids, to detailed chromatography and time-dependent drug release, we present a close up look at these microscopic methods in action.
