Pharmaceutical innovation and research are putting more and more emphasis on delivery methods that maximise therapeutic outcomes while minimising negative effects. One of the cutting-edge subfields of controlled medication administration is the oral drug delivery system. The most significant benefit of such a dose form is patient compliance. Sustained release dosage forms are designed to release a medicine at a set rate in order to keep the drug concentration constant for a set amount of time with the fewest side effects. By eliminating fluctuations in the therapeutic concentration of a medicine in the body, sustained release formulations are also offering a promising technique to reduce side effects of medication.
