Selain meningkatkan kemudahan, sediaan lepas lambat juga meningkatkan keamanan obat karena absorbsi dan pelepasan yang perlahan, sehingga kadar obat dalam tubuh berada pada rentang aman dan tidak mencapai puncak yang mendekati kadar toksik yang berbahaya.

The scientific rationale for the development of controlled drug delivery systems is always to decrease the dose and frequency of dosage, lowering the fluctuations of blood plasma ranges, affected person compliance and adverse consequences, and a reduction in the toxicity of your drug. The rate of availability of the drug in your body is maintained via the physiology of absorption inside the instant release system of your drug whereas, in the situation of the controlled drug delivery, the rate of administration is determined by the dosage with the drug. The key purpose with the controlled drug delivery is always to minimise the frequency of drug administration. To attain the required therapeutic concentration on the drug and to maintain the concentration from the drug for a specific time, the delivery agent is designed up of two pieces.

As sustained release delivery platforms keep on to evolve at today's swift speed of innovation, clinicians and individuals alike can look ahead to supplemental therapeutic selections that may be accessible to them in the future.
