There are various drug-delivery approaches designed for effective colonic disease treatment, including stimulus-based formulations (enzyme-triggered systems, pH-sensitive systems) and magnetically driven drug-delivery systems. In addition, targeted drug delivery by means of overexpressed receptors also offers site specificity and reduces drug resistance.

Background: Folic Acid conjugated liposomes encapsulating Oxaliplatin (L-OHP) were entrapped in alginate beads and further coated with Eudragit-S-100 for effective delivery to colon tumors.
Methods: Liposomes were prepared by cast film method and folic acid was coupled on the surface of liposomes. They were further entrapped in alginate beads which were Eudragit coated for degradation in the colonic region.
One of the most significant characteristics of cancer cells is their rapid dividing ability and overexpression of LDL receptors, which offers an opportunity for the selective targeting of these cells. 5-Fluorouracil (5-FU)-encapsulated low density lipid nanoparticles (LDLN) were prepared by the emulsion congealing method which mimics the plasma-derived LDL by acquiring the apolipoprotein B-100 from the blood. The average particle size, transmission electron microscope (TEM), and drug content of the prepared LDLN dispersion were found to be 161±3.

The indispensable obligation behind the successful therapy of a disease is to deliver the effective drug/bioactive concentration with sustained release manner at the diseased organs without any exposure to the healthy tissues. Novel drug-delivery systems increase the concentration and persistence of drug at the vicinity of the target site and thereby minimize the undesired side effects of the drug to the normal tissues of body. With advances in nanotechnology, several new drug delivery approaches have become available that may fulfil the requirement of safe and effective drug therapy.
