Novel Carriers for Coenzyme Q10 Delivery.

BACKGROUND

Coenzyme Q10, a natural yellow benzoquinone, is a vitamin-like substance commonly found in blood and inner mitochondrial and cellular membranes. It is a natural antioxidant principle which plays an essential role in maintaining several biochemical pathways of body. It has exhibited many pharmacological activities in chronic heart failure, cardiofaciocutaneous syndrome, diabetes mellitus, carcinomas, autoimmune disease, cataract, asthma, periodontal disease and thyroid disorders. Moreover, it has demonstrated efficacy as nutritional supplement, in addition to its relevance in cosmetics.

OBJECTIVE

Coenzyme Q10 is a potent molecule but its high molecular weight and low aqueous solubility hamper its use as a therapeutic agent. Therefore, various novel drug delivery systems have been explored and developed to overcome these limitations in literature. Hence, objective of this review is to summarize the recent works on design and development of novel drug delivery systems for CoQ10, which include liposomes, polymeric nanoparticles, polymeric micelles, solid lipid nanoparticles, nanostructured lipid carriers, self-emulsifying drug delivery systems, nanoemulsions, solid and aqueous dispersions. Further, an account of pharmaceutical studies has also been given.

RESULTS & CONCLUSION: The reported studies indicate the promise of nanotechnology in enhancing the therapeutic value of CoQ10, promoting its usage as first line therapeutic agent, thus, revolutionizing its role in current medical therapy. The application of CoQ10 in pharmaceutical industry has grown tremendously in the past decade, due to its versatile nature. The successful application of this molecule in medicine, cosmetics and nutraceuticals points the way for its future development.
