Abstract

The turmeric (Curcuma longa) plant, a perennial herb of the ginger family, is an agronomic crop in south and southeast tropical Asia. The rhizome is coined as the most useful part of the plant and a staple in all cooking and treatment of medicinal purposes include antioxidant, anti-viral, anti-bacterial, anti-fungal, anti-carcinogenic, anti-mutagenic and anti-inflammatory. It has a wide array of affinity to biological proteins and inhibits various kinases. Curcumin modulates the activity of several transcription factors, regulates the functioning of inflammatory enzymes, cytokines, adhesion molecules, and apoptic proteins. Recent preclinical and animal studies revealed the anti-proliferative, anti-invasive and antiangiogenic activity5,6. Clinically, Curcumin is proven to be safe while administering at larger doses, but due to poor aqueous solubility, quick systemic elimination, scanty tissue absorption and degradation at alkaline pH, which restrains its bioavailability, following strategies are used to enhance the bioavailability: (i) adjuvants like piperine which interferes with glucuronidation, (ii) liposomal curcumin, (iii) nanoparticles, (iv) Curcumin phospholipid complex and (v) structural analogues of curcumin. (VI) Micronisation and nanonisation (VII) self-microemulsifying drug delivery systems (SMEDDS), (vii) cyclodextrin inclusions, (IX) solid dispersions (X) Nanoemulsions, nanospheres, nanobeads, nanofibres7. The intention of this comprehension is to present a retrospective and prospective gist of applications of innovative delivery systems of Curcumin employed by the researchers to optimize Curcumin delivery using natural polymers with the objective of enhancing solubility and bioavailability, which might revolutionize the therapy of challenging chronic disorders of mankind.
